EXECUTIVE
SUMMARY
Ÿ
This
comprehensive review -
which has been put together by the parent of a child who became autistic
after immunisation -
sets out the concerns of parents whose children have degenerated into an
acquired-autistic state after MMR or other vaccines, and attempts to summarize
the debate over thimerosal (or thiomersal) preservative used in vaccines other
than MMR, and to highlight possible links between this mercury-based
preservative and autism. It is possible, and increasingly likely, that the MMR
and thimerosal factors overlap in the cause of late-onset degenerative autism.
Ÿ
These
are immense and complex subjects. This briefing does not attempt to cover every
single piece of the available scientific literature for or against an MMR/autism
or thimerosal/autism link, but it reviews about one hundred of the most recent,
most pivotal, or most frequently-quoted studies and papers.
Ÿ
Its
key finding is that there has not been a single credible study that can robustly
refute the claims of the parents that their children’s acquired autism has
been caused by MMR or related measles-containing vaccines, or thimerosal-containing
vaccines.
Ÿ
The
concept of vaccination is not the issue. No attempt is made here to criticize
the principle of vaccination. It has been argued that vaccines have saved
millions of lives, and continue to do so, particularly in the developing world.
Ÿ
The
issue here is, have a small minority of children been damaged by vaccines, in a
way that has yet to be fully understood? Specifically, is a subset of the autism
spectrum causally linked to certain types of vaccine, or vaccine ingredients?
These are the questions that are addressed.
Ÿ
This
document is in no way an “anti-vaccine” tirade. But if there is a problem,
even for a small sub-set of children, it must be investigated, and its
consequences faced up to. We do not shrug-off air travel fatalities, or deaths
of passengers traveling by rail. Yet possible vaccine damage seems to have been
largely ignored in the past, and the issue of safety treated as a taboo subject.
Vaccine safety monitoring, and even the wider issue of drug and pharmaceuticals
safety, has been in need of major reform, for many years.
Ÿ
Each
of the studies that seeks to “disprove” an MMR/autism link or a thimerosal/autism
link can be argued to be flawed in design or ambiguous in results. These flaws
are discussed in detail in the text.
Ÿ
It
also notes that all but one of the studies that seek to disprove an MMR/autism
or a thimerosal/autism link did not look at the actual children themselves, but
rather were based upon statistical analyses of the medical records of the wider
population. Such epidemiological studies are not appropriate to the
identification of relatively-rare adverse outcomes, and have indeed been
criticized by professional statisticians.
Ÿ
Such
studies also fail to address the problem -
what was it that damaged the specific children that became autistic after
MMR or thimerosal-containing vaccines?
Ÿ
The
one MMR study that has both claimed there is no MMR/autism link
and also actually looked at information extracted from the medical records of a
sub-set of UK damaged children was unable to prove or refute the suggested
association with MMR on the basis of the information available
- although it went on,
despite this, to insist that MMR was safe. And
- note
- this was still not a clinical study. No children were
actually clinically examined.
Ÿ
Parents
who have scrutinised the studies quoted by the Department of Health as
“proof” of there being no link between MMR or thiomersal and autism have
found that such studies crumble away easily when pressed. To give just one
example, the Finnish study by Patja, Peltola et al was very loudly heralded at
the start of 2001 by the UK Department of Health as convincing and conclusive
proof that MMR was safe. After intense critical scrutiny by parents and media,
by the end of 2001 the Medical Research Council was forced to admit that Patja,
Peltola et al’s original 1998 paper “did not examine the relationship of
MMR and autistic spectrum disorders.....and does not therefore provide useful
evidence on this point.” Of the subsequent paper by Patja, Peltola et al,
the MRC admitted: “The findings need to be interpreted with some caution,
as cases of autistic spectrum disorder or bowel disorders not considered at the
time attributable to MMR would not necessarily have been reported”. Quite
a retreat. Yet the study still continues to be regularly quoted by medical
commentators and professionals as “proof” that MMR is safe.
Ÿ
In
contrast, the parents find that there is a considerable, and growing, number of
studies that suggest that MMR and/or thimerosal preservative (routinely used in
very many vaccines until very recently, and still in widespread use in 2005)
could be causing acquired autism (or “autistic enterocolitis”) in
significant numbers of children.
Ÿ
Contrary
to the claims of the authorities, particularly in the UK, not all of these
studies originate from only one group of researchers (the former Wakefield team
at the Royal Free Hospital London, and then Dr. Wakefield since his departure),
as has sometimes been inaccurately asserted by those who defend MMR. The studies
that point to a link have involved a growing number of research teams, in
several countries. Other studies, whilst not specifically targeting MMR or
thimerosal-containing vaccines, offer further clues as to what may be happening,
and are consistent with an MMR and/or thimerosal involvement, implicating
vaccines.
Ÿ
Furthermore,
many of the studies that suggest that there is an MMR/autism or a thimerosal/autism
link are based upon the scientific analysis of data gathered from detailed
individual medical examination, and upon medical samples taken from the children
concerned. These are the studies that actually seek to address the two key
questions, “what is the damage sustained by this specific child, and
what exactly precipitated the damage to this specific child?”.
Ÿ
A
“house of cards” has thus been constructed by the UK Department of Health,
the US Government health system and by other authorities and commentators in the
medical establishment over the past five years, with repeated assurances being
given to the public, but with these being based upon a lop-sided, highly
partisan and culpably selective gathering and interpretation of the available
evidence.
Ÿ
This
briefing note also finds that there are other related concerns
- from the regulatory bodies
themselves -
about the risk of permanent developmental damage from thimerosal-containing
(or thiomersal-containing) vaccines, though it is not yet completely understood
as to how these problems are directly interlinked biologically to the MMR/autism
problems (we are told that MMR in itself does not contain thimerosal).
Class-action lawsuits are now under way in the US (see later sections) over
thimerosal/thiomersal and autism, just as they have been (or still are) in the
UK and Ireland over MMR and autism.
Ÿ
Although
complete and precise scientific proof of how the children have been damaged by
vaccines and become autistic is still emerging, there have been numerous vital
clues over the past six years and more -
clues that all too often have been ignored, or, worse still, have been
rejected out of hand by the authorities.
Ÿ
The
medical establishment has repeatedly asked itself the wrong question. It has
asked itself “Is MMR safe?”, and “is thimerosal safe?”, hoping for an
affirmative answer. In contrast, researchers and parents have asked two very
different questions: “What precisely is wrong with this child?”, and “Why
did this child change from being healthy to being autistic?”. It is
answering these latter two questions that should be the key issue.
Ÿ
The
safety trials of MMR were undoubtedly very poor. That is an established fact.
For the thimerosal issue, the picture is even more stark. The product appears to
have had no proper safety trials since its introduction about 75 years ago, and
its use appears to have lacked any appropriate back-checks on safety.
Ÿ
Much
of the debate within the medical community appears to have been based around the
simplistic assumption that, for example, if MMR caused autism, there should be
matching graphs showing the uptake of MMR and the uptake of autism. For example,
in Spring 2005, Dr. William Barbaresi of the Mayo Clinic, Rochester, Minnesota,
commented that children had been given MMR for almost twenty years before there
was a marked increase in US autism. The possibility that children had, for
example, been damaged in gradually-increasing numbers by the introduction of MMR
and then the later acceleration of the vaccination schedule using
increased total burdens of thimerosal for each child, in combination, in
combination, producing a delayed-action increase in autism numbers, does not
seem to occur to the medical establishment. It is rather like road accidents.
Accidents are caused by driver behaviour, vehicle design, vehicle speeds, road
design, road condition, weather and other factors, in combination. You do
not expect to find a precise historic straight-line linear relationship over
decades between (say) “numbers of drivers” and “numbers of deaths”. Life
is more complex than that.
Ÿ
The
children that have been damaged have had their lives ruined. They were
previously completely healthy. They now have seventy or eighty years of mental
handicap ahead. Whether their sacrifice is justified in the interests of wider
public health is not the point at issue. What is at issue is, what changed for
these children, through what processes, involving what susceptibility factors
and trigger factors. And how can further cases of damage be headed-off?
Ÿ
This
briefing note also poses a number of unanswered questions about MMR, about
thimerosal, and about the children
that are believed to have been severely damaged by vaccine administration. The
damage involved is not confined to regressive autism.
Ÿ
Finally,
it is emphasized that this note is the result of a search of the published (and
sometimes unpublished) studies and other information. It does not offer medical
advice. Parents considering vaccinating their children with MMR or with
thimerosal-containing vaccines must form their own conclusions as to whether to
proceed, and are urged to gather the maximum amount of hard information before
making their own choice. It is hoped that this Briefing Note offers a useful
start, and is useful for journalists.
PART
A
A
NOVEL SYNDROME
1: What Is Acquired Autism/Autistic
Enterocolitis?
Ÿ
Autism
is not an illness in itself, so much as a manifestation of a dysfunction in
certain parts of the central nervous system, particularly affecting language,
cognitive and intellectual development and the ability to relate to others. It
is an effect, and a consequence, not a cause in itself. Everything has a cause.
Autism is not some mysterious illness that comes out of the sky, to strike
children at random. It is a global term, all too loose, to describe a set of
characteristics.
Ÿ
The
“classic” form of autism was first described by Dr. Leo Kanner. These
children were different from normally-developing children from birth.
Ÿ
However,
a very different form of autism, formerly a minority variant, has now begun to
predominate. In this, children develop normally, passing all their developmental
milestones, and then later acquire an autistic-like condition. They lose their
previously-demonstrated speech, learned behaviour and social skills. In effect,
they dissolve into a state of mental impairment, of varying severity. Often the
damage is severe or very severe, and usually the damage appears to be permanent,
although some remedial treatments are claimed to be able to reverse some aspects
of damage to a modest degree.
Ÿ
This
late onset of autism typically follows the receipt of MMR vaccination, but also
appears to sometimes follow measles-containing vaccines such as monovalent
(so-called “single”) vaccine, or measles-rubella (MR) vaccine, and sometimes
other vaccines such as DPT (diptheria-pertussis-tetanus).
Ÿ
It
does not necessarily occur immediately after MMR - onset of
autism is not in any case an “acute” reaction
- and there are now grounds
for believing that onset following vaccination may be very gradual indeed,
spread over at least many weeks, more probably several or many months, or even
in some cases several years. The rate of deterioration seems to vary
considerably. It has been a consistent error of the medical authorities to view
autism as an alleged acute, immediate, reaction, although many parents have
certainly reported than some form of immediate or near-immediate (within 24
hours) adverse reactions, such as high-pitched screaming and high temperatures,
have occurred. Some parents have reported a rapid change in their child’s
behaviour, whereas others have seen a slower decline. Typically, the child’s
mood has changed, they have become quiet and withdrawn, speech has been lost and
skills have vanished. Sleep patterns have often disintegrated.
Ÿ
Crucially,
the onset of this acquired form of regressive autism is accompanied by other
visible and associated physical manifestations of problems. These include bright
red ears and dark rings under the eyes after certain foods, acute gluten and
casein intolerances, prolonged hyperactivity, night sweating and loss of
temperature control, and chronically poor sleep patterns.
Ÿ
The
arrival of these problems and the degeneration of the child into autism as a
“package” strongly suggests that they are interconnected
Ÿ
The
timing of onset following vaccination -
not just MMR -
is described by the UK Department of Health as a coincidence. Their
argument is that autism is “noticed” around this time, because this is a
time when child development is most rapid, and therefore any failure most
noticeable. The thinking behind this stance appears to be that either autism was
always there, all along, or that it is akin to some sort of delayed-action
genetic “bomb”, primed in certain individuals to detonate just after receipt
of MMR or thimerosal-containing vaccines, or around that time.
Ÿ
The
gross implausibility of this argument, that it is highly unlikely in the extreme
that previous problems would have been missed, and at a time where children
receive constant devoted attention and close scrutiny regarding their
development, is ignored. The concept that genetics alone could be responsible
for sudden devastating decline in a developing infant is equally implausible.
Ÿ
Photographic
and video evidence, together with child health and developmental records and the
accounts of relatives, friends and visitors, that contradicts the authorities’
arguments, is also routinely ignored, without even a superficial investigation
to verify their accuracy.
Ÿ
However,
very significantly, much older children have also degenerated into autism after
MMR or other vaccination. If degeneration in affected children always follows
immunisation with MMR or measles-containing vaccine, regardless of the age of
the child, then it implies that the link is not coincidental.
Ÿ
Also,
no cases are known, at least to campaigning parents, of any children who have
rapidly become autistic just before MMR or thimerosal-containing
vaccines. This clearly implies that such cases are much fewer in number.
Ÿ
Also,
it is not simply a failure to develop. The children have developed normally,
then inexplicably acquired their autistic state. This protracted event has been
directly observed by parents and relatives, and in many cases recorded on
photographs and video footage.
Ÿ
There
is also the issue of double-regression, where children have been normal, have
been vaccinated, have regressed, have made some remedial progress, have been
re-vaccinated (as a booster) and have severely regressed again. This principle
is known as challenge-rechallenge. The US Institute of Medicine has stated that
evidence of challenge-rechallenge would constitute powerful support for a causal
link between vaccines and regressive autism. There are many UK children (and
presumably US children, too) who offer such evidence, but the IoM has not yet accepted
that its self-declared criteria has been fulfilled.
Ÿ
No
credible alternative explanation for why a previously-healthy child should
become severely autistic has been put forward. The unheralded acquisition of a
state of severe disability, in a substantial number of hitherto-healthy
children, has to have a significant causal trigger. A growing number of
scientists, as well as parents, believe that the trigger is either MMR, or
thimerosal, or both acting in synergy.
Ÿ
Undoubtedly
there are other factors involved, pointing to a predisposition of certain
children to be vulnerable to damage, of varying severity. Research should be
trying to pinpoint those factors, but patently is not. Research is being held up
by the refusal of the medical establishment in the UK and US to recognise the
problem, or even to recognise the reality of a steep increase in autism.
Ÿ
Also
coinciding with the late onset of autism in many of the children (or other
severe damage -
autism is not the only manifestation of there being a problem), has come
gastrointestinal problems such as alternating bouts of diarrhoea and
constipation, chronic abdominal pains and bloating.
Ÿ
Examination
of children, initially but not exclusively at the Royal Free Hospital, London,
has identified a novel form of inflammatory bowel disease, ileal-lymphoid
nodular hyperplasia. This has emerged after ileocolonoscopy of affected children
and analysis of samples. The pioneer research the Royal Free has now been
confirmed by researchers at other centres in Ireland and the US.
Ÿ
The
simultaneous onset of these problems after a normal early development suggests
that it is highly likely that these other elements are linked into the
biological explanatory sequence of autism, notably through the pathway of gut
damage and either the penetration of the blood-brain barrier or the triggering
of some other process, such as serious myelin damage (in basic terms, the myelin
sheath is the “insulation” around the neurons or “wires” of the brain).
Ÿ
Research
reported by Dr. Jeff Bradstreet to the US Institute of Medicine on 9th February
2004 found that, when the cerebrospinal fluid of 28 regressive-autistic children
was analysed, measles virus was found in 19 of the 28 cases. When 37
non-autistic control-group children were analysed, only one child was found to
have measles virus. All 65 of these children had received MMR, and none had any
recorded history of wild measles infection. This more recent research is
powerful statistical evidence of a measles virus complicity in the pathogenesis
of regressive autism. This research therefore strongly endorses the anecdotal
evidence of the parents, that their children became autistic after MMR. For many
children, MMR thus remains the prime suspect.
2: The New Syndrome
This
is a very brief summary of the new syndromes of autistic enterocolitis and/or
mercury damage:
Ÿ
In
a 200-strong cohort of children examined through ileocolonoscopy at the Royal
Free Hospital, London, an almost 100% incidence of ileal-lymphoid nodular
hyperplasia has been found. This condition manifests itself as swollen lumps
throughout the intestinal tissue of autistic children. The condition is very
rare in non-autistic children.
Ÿ
The
condition is believed to have developed in each case in the period following MMR
immunisation
Ÿ
Because
of the swollen and hyperplasic condition of the intestinal wall, undigested
toxins , having not been stopped by either the intestine or the liver (which can
also be damaged) may then be able to attack the central nervous system. The
evidence for the complete pathway of damage is uncertain at present, due to lack
of research.
Ÿ
An
alternative pathway of damage may be that the virus(es) in the vaccine, or other
constituents of the vaccine, may be inflicting the actual damage, or interfering
with the brain’s further development by damaging myelinisation. Comprehensive
studies to determine this have also yet to be undertaken.
Ÿ
It
is also possible that thimerosal, a mercury-based preservative that has been
routinely used in a number of vaccines, may have played a role. The resultant
damage closely resembles that of mercury poisoning. Again, adequate research has
not yet been done.
Ÿ
Damage
may in the event be via either, or a combination, of these pathways.
PART
B
THE
SCALE OF THE AUTISM PROBLEM
3: The Financial Costs
- Autism Is Costing The
Taxpayer £$Billions
Quite
apart from the immense social costs of autism for individual families, there are
the huge financial costs. Autism effects every UK and US taxpayer, not just the
families with the children. In the UK, the costs comprise:
Ÿ
Health
costs - specialist hospital visits, GP visits, prescriptions,
exclusion diet costs - passed on to the taxpayer
Ÿ
Major
education costs -
special schools, extra teachers, extra teaching assistants, extra
training, management - passed on to
the taxpayer
Ÿ
Transport
costs for schooling and respite -
taxis plus drivers and escorts, plus local authority management costs,
plus environmental/congestion costs of extra traffic
- passed on to the taxpayer
Ÿ
Significant
childhood social services costs -
respite care staff costs, management, inspection, reviews
- passed on to the taxpayer
Ÿ
Later
special transport costs in adult life (during lifelong care)
- funded by the taxpayer, as
the person with autism will almost certainly have no income
Ÿ
The
immense costs of sheltered accommodation during adult life (lifelong costs),
again including social services, management, inspection, and also including
furniture and other allowances, all passed on to the taxpayer
Ÿ
The
immense loss of earnings of the affected person (lifelong)
Ÿ
The
loss to the Government of their national tax revenues (lifelong)
Ÿ
The
loss to local government of their Council Tax revenues (lifelong)
Ÿ
Loss
of earnings of parents whilst acting as carers
Ÿ
Loss
of the parents’ tax revenues whilst caring
Ÿ
Carers
allowances (paid to parents when they are acting as carers), the costs of which
are passed on to the taxpayer
Ÿ
Disability
living allowances, often at the higher rate (lifelong), including care and
mobility components, passed on to the taxpayer
Ÿ
Incapacity
benefit (lifelong beyond age 16), passed on to the taxpayer
Ÿ
Wider
economic costs -
other losses of gross domestic product and other non-financial
contributions to the national economy
It
would be interesting to know if the UK (or US) Treasury had a view on these
costs, and whether sufficient resources were being devoted to investigating
acquired autism and other forms of autism, as they represent a massive loss to
the local and national taxpayer and the national economy.
These
costs will grow as more and more children become autistic and as more of the
existing children reach adulthood and leave home. The affected people almost
certainly won’t be paying these costs as children, nor even as adults, as they
almost certainly won’t have any income. And once the children reach adulthood,
the parents won’t be paying them, either.
As
these costs soar, the question becomes, “is autism too important to be left to
the Department of Health, a Department that has done virtually nothing to
investigate its causes”? - or to its counterparts in the US and elsewhere? Is this just
a private matter for the medical community, or a matter for a wider audience?
And, for the medical safety regulators, “who guards the guards”? Does a
Minister control his/her advisers, or do his/her advisers control the Minister?
4: Overall Cost Estimates
In
June 2000 a study for the UK Mental Health Foundation found that
Ÿ
the
annual costs of autistic disorder in the UK were at least £1 billion
Ÿ
individual
lifetime costs per child affected could run to £2.94 million each.
The
full costs, taking into account wider economic costs, are probably considerably
higher still.
If
one reduces the £2.94m per child by an arbitrary 33%, to allow for the fact
that many children are less severely damaged than the maximum, and will thus
cost less to care for, one is still facing a bill of £2m for lifelong care, not
counting other wider costs such as loss of tax revenues from the autistic person
an (when their parents care for them) their carers, plus other costs such as
carers’ allowances (a UK scheme). The degree of severity and precise costings
could be debated at length, but are clearly extremely large for severe cases.
Another
way of looking at it is to compare the UK with the US, which has hard
State-collected data. According to the Individuals With Disabilities Education
Act data, the US autism numbers (with four times the population) stood at
120,000 in early 2003 (amongst 6-21 year olds in full time education).
If
UK cases currently run to around a quarter of this figure, 30,000 to 35,000,
then total economic costs for the UK could be immense. A reasonable estimate
would be that 35,000 cases would cost the UK taxpayer somewhere between £35
billion and £100 billion spread over perhaps seven decades, or between £500m
and £1.4 billion per annum. A mid-range answer probably lies in the £20
billion to £40 billion-plus range, spread over five to six decades, and even
that latter figure works out at £700 million per year. And that is only for the
UK.
Even
if these costs are being seriously overestimated here, they are still immense.
And they could represent an underestimate, especially if there is economic
damage from the milder cases that are probably not included in the statistics.
There is also the prospect of cases being added to the total, all the time, now.
Any annual increase in cases of, say, ten per cent would lead to all these
estimates having to be re-doubled a decade on.
And
this is wholly irrespective of any MMR-autism or thimerosal-autism link
being proved, because the children already exist, even if the cause of
their illness remains disputed. The children are out there, now, and these bills
are being passed to the taxpayer, now, today. The costs meter is already
running, but the immense scale of the bill is partly obscured by it being spread
amongst many central and local government (or Federal and State) budget
headings, and amongst numerous lesser authorities.
5. Failure To Monitor Increases In UK Autism
Numbers
Ÿ
There
has been a consistent argument on the part of the authorities, and those seeking
to defend MMR, that the apparent rise in autism may be largely a matter of
better recognition. This has received some backing from autism researchers. But
where hard UK or US data is available, increases are far too steep, and in far
too short a timescale, to be credibly ascribed to better recognition alone..
Ÿ
For
this to be “better recognition” or “improved diagnosis”, this would have
required these children to have been missed, simultaneously, by their parents,
their relatives, their doctors and their teachers in the past This is simply not
credible. For example, the increase in autism 1992-99 in Wakefield, West
Yorkshire, UK, local education authority was from 5 cases to 111 cases. If
increased autism is down to better recognition, it would mean that, back in
1992, there really were 111 cases, but only 5 were recognised, and the
remaining 106 were missed, and by all the parties
- parents, doctors, health
visitors, teachers - concerned.
This is completely implausible.
Ÿ
Undoubtedly
there has been some degree of better recognition and reclassification, following
introduction of ICD-10 (international classification of diseases/disorders)
criteria in 1992, and DSM-IV (diagnostic statistics manual) criteria in 1995.
But this will account for only a minority of the growth.
Ÿ
The
UK Department of Health has failed to monitor autism, and is still failing to
(despite a specific 1997 recommendation of the House of Commons Health Committee
to do so). Is it now afraid of what it might find? If it does decide to monitor
autism, will it find that numbers are high and then claim it has always
historically been so?
Ÿ
UK
Health Boards/Authorities are also failing to monitor autism locally. Health
Boards/Authorities have little data and no consistent approach. At the health
authority level, official figures vary wildly, by factor of 300-fold, i.e. 300-times
(not 300%). The data is an extraordinary mess.
Ÿ
In
fact, most UK data is actually non-existent. In the year 2000, only 1 in 6 UK
Boards/Authorities had any credible figures at all. Most used estimates
from textbooks.
Ÿ
The
Scottish schools census now includes autism. The census commenced in 1998. The
1998 figure was around 750, but by year 2000 this had climbed steeply to about
1,250, and by 2002 it stood at approaching 2,200.
Ÿ
There
are other indications of the level of increases: Kaye et al paper (see later)
found a sevenfold increase 1988-99 in UK. An unpublished 1999 paper by Dr. Fiona
Scott, Autism Research Unit, Cambridge, indicated autism at eleven times the
expected level (1 in 174) -
see later.
Ÿ
The
2001 Medical Research Council review found autism to be at 1 in 166, many times
higher than hitherto thought. Sixteen studies published between 1966 and 1991
found rates of between 1 in 3030 and 1 in 625. A rate of 1 in 166 is nearly four
times higher than 1 in 625, itself the highest of these sixteen, and only from a
relatively-recent study in 1983. If you take a rate of 1 in 1830 as being the
mid-point of these historic rates, then a rate of 1 in 166 is eleven times
higher.
The
repeated official line that the apparent increase is down to better recognition
is little more than a counsel of complacency.
In
December 2002, a Parliamentary Written Question (84502) confirmed that there is
now in place a “Good Practice Guidance on Autistic Spectrum Disorders”, in
the UK, published by the Government’s Departments of Education & Skills
and of Health. This is intended to raise awareness amongst schools and local
education authorities. However, it is probably just one of many thousands of
such well-intentioned documents, is non-statutory, and is probably lost in the
stream of paper raining down on local government from central government.
UK
schools and local education authorities have a duty to identify, assess and make
suitable provision for children with special educational needs. However, there
seems to have been no duty upon either the health authorities at the local level
or the Department of Health at Government level to improve the data position
over autism -
doubtless to the latter’s relief. Perhaps centrally-collated figures
showing steep increases would beg uncomfortable questions as to the causes. The
UK Department of Health seems to regard autism as a problem for local education
authorities - not for the Department.
It
is understood that from January 2004, a first survey in England will be
undertaken of disabilities amongst children receiving special needs education.
This will be the UK (England-only) Pupil Level Annual Schools Census (PLASC).
English local education authorities and the schools in their areas have to
supply data about the numbers of pupils with different types of special
educational need, including autistic-spectrum disorders.
However,
it may be some time before data is available, and obviously it will be several
years before any clear trend emerges. Any past steep rise during the 1988-2004
period will therefore of course have been missed, although some idea of
increases may be available if data is stratified by age (this is not known at
time of writing).
There
has been a similar failure to monitor numbers closely in the US, although the
data position is considerably better, as will be explained later. The data
position elsewhere is not known, but is almost certainly either very poor or
non-existent.
6. “Now Almost Everyone Knows Someone
Who’s Autistic”
Autism
was a very rare condition, but is now almost regarded as commonplace. Very many
cases are now of late-onset autism, whereas almost all used to be cases from
birth. We have to ask why this is.
Some
UK research noted the sharp increases in autism in the 1990s. A paper by Powell
et al, Department of Public Health and Epidemiology, University of Birmingham,
UK, Changes in the Incidence of Childhood Autism and Other Autistic Spectrum
Disorders in Pre-School Children from Two Areas of the West Midlands, UK,
was published in Developments in Medicine and Child Neurology, September 2000.
This looked at the incidence of childhood autism and ASD in pre-school children
between 1991 and 1996.
The
study found that there were year-on-year increases in classical autism during
this period of 18%, but for “other ASDs” the annual increase was no less
than 55%. But the study then concluded that this was due to clinicians being
increasingly able or willing to make a diagnosis. The possibility of an
underlying genuine increase, and any follow-on question as to causes, does not
appear to have occurred to the study team.
But
parents of children believe to have been damaged by MMR strongly believe that
part of the increase is down to a new phenomena, autistic enterocolitis.
It
is not the autism of the past. Such a severe acquired regressive syndrome
after a normal early childhood would have been noticed at once in the past by
parents, and recognised medically, and also reflected in much higher historic
rates of prevalence/incidence. Regressive autism used to be a minority variant:
Now it is clearly the predominant form, by a very wide margin.
Dr.
Bernard Rimland, President of the US Autism Research Institute, has concluded,
after a thorough analysis of the ARI database: “Late onset autism (starting
in the second year) was almost unheard of in the 1950s, 1960s and 1970s. Today,
such cases outnumber early onset cases by five to one, with the increase
paralleling the increase in required vaccines”.
In
the parents’ view, there is clear evidence of recent dramatic rates/increases
in autism:
Ÿ
Some
UK examples - an East Surrey 1/69 rate amongst three year old boys, 1/139
rate amongst three year old boys+girls combined (source: personal communication
of 10/6/99 from Caroline Clark, Commissioning Manager, Learning Disability
Services, East Surrey Health Authority). The letter from East Surrey stated: “In
the remaining half of the District, it is estimated that there are at least 50
children on the autistic spectrum under the age of five. A special needs audit
has been undertaken of children aged three by the community paediatrician. This
is the age where the paediatrician expects to identify children at the more
severe end of the autistic spectrum. Thirty-six children have been identified
during the last two years as presenting with autism, of which twenty-nine were
between the ages of two and three, with seven children slightly older. The
general population is around 2,500 children (born) per year in this part of the
District. The prevalence of autism indicated by the audit is 0.72% (1 in 139)
but with 1.44% (1 in 69) for young boys.”
Ÿ
Bromley
Autistic Trust figures show a 1990-94 increase of 280% over 1980-84 figures
(source: personal communication of 16/9/99 from Miss C. M. Povey,
Services Director, Bromley Autistic Trust)
A local
survey carried out in the Inverness area in 2003 found that 1 in 49 children was
on the autistic spectrum.
Ÿ
Wakefield
LEA autism pupils rose from 5 to 111 in seven years (source: survey by David
Brown, a specially-seconded headmaster from the Park School, Wakefield, on
behalf of Wakefield Local Education Authority, 1999)
Ÿ
Telford
health data up from 4 new cases per year in 1990 to 17 per year 1998 and again
1999 (source: personal communication of 20/11/00 by Dr F. R. J.
Hinde, Consultant Paediatrician, Princess Royal Hospital, Telford)
Ÿ
As
noted, Scottish schools census, repeatedly up year-on-year, and by a large
margin each year; from around 750 in 1998 to well over 2000 in 2002 (source:
Scottish Annual School Censuses, available from Scottish Education Office, tel
0131 556 8400)
The
problem isn’t confined to autism. On December 22nd 2002, the (UK) Observer
newspaper carried a report on the apparent epidemic of behavioural problems
amongst UK schoolchildren. Whilst not autism (the report cited hyperactivity and
attention-deficit disorder), the Observer’s report suggested a steep rise in
the incidence of problems. Figures obtained by the newspaper suggested that
numbers of schoolchildren with attention-deficit disorder (ADD) or
attention-deficit hyperactivity disorder (ADHD) had reached 345,000, and that
one child in twenty between the ages of 6 and 16 years had one or other
condition. The Observer also found out that prescriptions for Ritalin, to
counter these disorders, had increased markedly, from 91,100 in 1997 to 208,500
in 2001.
In
the US, the Brown University Child & Adolescent Behavioural Letter (18(3):
1: 304, 2002) carried the following details:
Ÿ
A
study into attention deficit hyperactivity disorder (ADHD) was undertaken, based
on parent and teacher reports concerning 6,099 children in 17 public elementary
schools. The study was undertaken by researchers working for the National
Institute of Environmental Health Sciences in North Carolina
Ÿ
When
the researchers surveyed parents in a typical county of rural and suburban
communities - Johnston
County, North Carolina - the parents reported that more than 15% of boys in grades 1st
through 5th had a diagnosis of ADHD, with about 10& (i.e. two-thirds of
those diagnosed) receiving medication.
Although
ADHD is not autism, it may share some common causal pathways, particularly
multiple food allergies and gut permeability. The finding is thus of interest to
the MMR/autism debate.
7. Is Autism Increasing Due To Changes In
Criteria?
This
has become a hotly-contested topic, as it is central to the vaccine/autism
controversy. But gradually, sheer numbers are silencing, or at least weakening,
the position of those who doubt that autism has greatly increased in a very
short space of time.
It
has frequently been asserted by Governments, some researchers and elements of
the medical establishment that the apparent increases in numbers of children
with autism can be ascribed to “looser” criteria for inclusion. This latter
point is demonstrably not the case. The criteria have in fact tightened-up.
Kanner’s
original concept of autism included five diagnostic features:
·
A
profound lack of affective contact.
·
obsessive
desire for the preservation of sameness
·
Fascination
for objects
·
mutism
or language that does not seem suited to interpersonal communication
·
feats
of memory, or skills in performance tests
Kanner
and Eisenberg, in 1956, emphasized two diagnostic criteria:
·
profound
lack of affective contact.
·
repetitive
ritualistic elaborate behaviour
They
considered that if these two key features were present, the other typical
features would also be found.
In
1980, the DSM-III (Diagnostic and Statistical Manual III) criteria were
introduced. These included:
·
“pervasive
developmental disorder” for the general category of autism.
·
“infantile
autism”
the category of infantile autism was defined as:
· lack of responsiveness to others.
· language absence or abnormalities.
· resistance to change and/or attachment to objects.
· the absence of schizophrenic features.
·
onset before age 30 months
In
1994, DSM-IV criteria were introduced. These criteria are more restrictive than
DSM-III, and so an increase in numbers between the DSM-III era and the DSM-IV
era cannot be explained by looser criteria, as the very opposite is the case.
For example, in Washington State, autism numbers actually fell when DSM-IV was
introduced.
It
is worth setting out in detail the criteria for autism and relating
autistic-spectrum disorder (ASD) conditions:
8. Autistic Disorder
For
DSM-IV, a total of six or more items from the following lists of (1), (2) and
(3) is necessary, with at least two items having to come from (1), and one each
from (2) and (3):
(at
least two from)
(1) Qualitative impairment in social
interaction as manifested by:
* marked
impairment in the use of multiple non-verbal behaviours, such as eye-to-eye
gaze, facial expression, body postures and gestures to regulate social
interaction.
* failure to develop peer relationships
appropriate to developmental level.
* a lack of spontaneous seeking to share
enjoyment, interests or achievements with others (eg by a lack of showing,
bringing or pointing-out objects of interest.
*
lack of social or emotional reciprocity
(at
least one from)
(2) Qualitative impairments in communication,
as manifested by at least one of the following:
* delay in, or total lack of, the development
of spoken language (not accompanied by an attempt to compensate through
alternative modes of communication such as gesture or mime)
* in individuals with adequate speech, marked
impairment in the ability to initiate or sustain a conversation with others
* stereotyped and repetitive use of language
or idiosyncratic language
* lack of varied, spontaneous make-believe
play or social imitative play appropriate to developmental level
(at
least one from)
(3) Restricted, repetitive and stereotyped
patterns of behaviour, interests and activities as manifested by at least one of
the following:
* encompassing preoccupation with one or more
stereotyped and restricted patterns of interest that is abnormal either in
intensity or focus
* apparent inflexible adherence to specific
non-functional routines or rituals
* stereotyped and repetitive motor mannerisms
(eg had or finger-flapping or twisting or complex whole-body movements)
* persistent preoccupation with parts of
objects
9. Pervasive Development Disorder - Not Otherwise
Specified (PDD-NOS)
The
DSM-IV criteria also included criteria for “pervasive development disorder-not
otherwise specified”, or PDD-NOS. This category applies to cases where there
is a severe and pervasive impairment in the development of reciprocal social
interaction or verbal and non-verbal communications skills, or when stereotyped
behaviour, interests and activities are present, but the criteria are not met
for a specific pervasive developmental disorder, or schizophrenia, or
schizotypal personality disorder, or avoidant personality disorder.
For
example, PDD-NOS includes “atypical autism”, presentations that do not meet
the criteria for autistic disorder because of late age of onset, atypical
symptomatology, or sub-threshold symptomatology, or all of these.
10. Asperger’s
The
DSM-IV criteria for Asperger’s Disorder (or syndrome) are as follows:
Qualitative
impairment in social interaction as manifested by at least two of the following:
* marked impairment in the use of multiple
non-verbal behaviours such as eye-to-eye gaze, facial expression, body postures
and gestures to regulate social interaction.
* failure to develop peer relationships
appropriate to developmental level
* lack of spontaneous seeking to share
enjoyment, interests or achievements with other people
* lack of social or emotional reciprocity
Restricted,
repetitive and stereotyped patters of behaviour, interests and activities as
manifested by at least one of the following:
* encompassing preoccupation with one or more
stereotyped and restricted patterns of interest that is abnormal in intensity or
focus
* apparently inflexible adherence to specific
nonfunctional routines or rituals
* stereotyped and repetitive motor mannerisms such as had or finger-flapping or twisting, or
complex whole-body movements
* persistent preoccupation with parts of
objects
The
disturbance causes clinically-significant impairment in social, occupational or
other important areas of functioning. There is no clinically-significant general
delay in language, eg single words are used by age two years, communicative
phrases used by age three years). There is no clinically-significant delay in
cognitive development or in the development of age-appropriate self-help skills,
in adaptive behaviour (other than in social interaction) and in curiosity about
the environment in childhood. Criteria are not met for another specific
pervasive developmental disorder, or schizophrenia.
11. Paper by Mark Blaxill, June 2001
The
issue of diagnostic criteria was also considered in a long and detailed paper,
“The Rising Incidence of Autism”, by a parent, Mark Blaxill, in June 2001.
This paper covered a number of aspects of the vaccine/autism controversy, and is
reported in several sections of this document. Coverage of diagnostic criteria
- and whether changes in
criteria have produced a “false impression” of an epidemic, were summarised
in the paper.
The
five most influential criteria groups that have formed a backdrop to the work of
epidemiologists have been:
* Kanner’s original work. Kanner’s
criteria were abandoned in the 1970s.
* Rutter’s attempt to modify and refine
Kanner’s work with the introduction of a categorical approach
* the codification of Rutter’s approach
within the Diagnostic Statistical Manual (DSM) series, termed DSM-III
* the modification of DSM-III into DSM-IIIR
(“r” for revised)
* attempts at producing an international
standard, with the use of DSM-IV and ICD-10 (International Disease
Classification-10)
From
Rutter onwards, all the criteria have attempted a categorical approach. A child
must exhibit specific significant impairments. Of the above four categorical
methods, differences can be compared as follows:
(Social
category)
* Rutter 1978, “impaired social development which has a
number of special characteristics (that are) out of keeping with the child’s
(normal expected) intellectual level”
* DSM-III 1980, “lack of responsiveness to others”
* DSM-IIIR 1987, “qualitative impairment in reciprocal
social interaction”, defined more specifically by the fulfillment of at least
two out of five criteria from a checklist
* DSM-IV 1994 “qualitative impairments in social
interaction” which are now defined by meeting two out of four criteria from a
checklist. These criteria include lack of eye contact, inability to form
friendships, lack of awareness of the feelings of others, and lack of
spontaneous play
(Language/communication
category)
* Rutter 1978, “delayed and deviant language
development that also has certain defined features and is out of keeping with
the child’s intellectual level”
* DSM-III 1980, “language absence or abnormalities”
* DSM-IIIR 1987, “qualitative impairment in verbal and
non-verbal communication, and in imaginative activity”, which was defined as
including at least one item from a list of six abnormalities. This included lack
of language, abnormal speech patterns, lack of eye contact, abnormal play
skills, abnormal conversation patterns and echolalia
* DSM-IV 1994, “qualitative impairments in
communication” which are now defined as any of four areas, including language
absence or delay, abnormal conversation skills, echolalia or abnormal pretend
play
(Behaviour
category)
* Rutter 1978, “insistence on sameness as shown by
stereotyped play patterns, abnormal preoccupation or resistance to change
* DSM-III 1980, “resistance to change or attachment to
objects”
* DSM-IIIR 1987, “markedly restrictive repertoire of
activities and interests”, which require meeting one of five conditions,
including self-stimulatory body movements, unreasonable insistence upon
routines, distress over small changes in the environment, preoccupation with
parts of objects and unusual preoccupation with narrow subject areas”
* DSM-IV 1994,”restricted repetitive and stereotyped
patterns of behaviour interests and activities” which requires meeting one of
four criteria, including self-stimulatory body movements, unreasonable
insistence on routines, preoccupations with parts of objects or unreasonable
preoccupation with narrow patterns of interest
Blaxill
notes that all four of these approaches share a great deal in common and reflect
relatively few differences. He concludes that it is very difficult to make the
case that a discontinuity in diagnostic concepts between 1978 (when Rutter’s
criteria replaced Kanner’s) and the present time (then 2001) could produce
increases of the magnitude recently reported. In other words, the major rises in
autism numbers cannot be solely explained by changes in the diagnostic criteria,
as is so often asserted by the medical establishment and by the US and UK
Governments.
12. University of Cambridge Research
On
18/2/01, the UK Sunday Telegraph reported on research undertaken by Dr.
Fiona Scott at the Autism Research Centre at the UK University of Cambridge. The
research, Prevalence of Autism Spectrum Conditions in Children Aged 5-11
Years in Cambridgeshire UK, by Scott, Baron-Cohen et al, which is due to be
published shortly, was undertaken across schools in Cambridgeshire.
The
study aimed to establish prevalence of the broader autistic spectrum, including
Asperger syndrome in 5-11 year olds in Cambridgeshire, UK. Cases of diagnosed
autism spectrum condition in children who were in Cambridgeshire schools and
aged 5-11 on 31st December 1999 were sought out using public records, screening
instruments, educational psychology and special educational needs coordinator
records.
It
found that:
Ÿ
One
in 175 (58/10,000) children was autistic, whereas previous studies had pointed
to a rate of 1 in 2000 (5/10,000)
Ÿ
This
was 11 times higher than the rate of classic autism, but in line with other
recent national and international rates for the broader spectrum.
Ÿ
In
responding mainstream schools, the prevalence was 1 in 300. In the responding
special schools, the prevalence was 1 in 8.
Ÿ
Extrapolated
across the UK, that would imply 30,000 primary school (age 5-11) children with
autism
Ÿ
The
overall sex ratio of the children was 4 to 1 male to female, but in mainstream
schools it as 8 to 1.
Ÿ
Linking
these rates to estimated costs of education and care for sufferers would give a
figure of as high as £5 billion per year, year after year. The Cambridge
autism figures were described as “if anything an under-estimate”.
They included only children with a definite clinical diagnosis. Any child who
had only been “statemented” (= educational needs-assessed) as autistic, but
not yet clinically diagnosed, was not counted
Ÿ
One
in eight children with special educational needs was suffering from some form of
autistic spectrum disorder. The increase of actual numbers over
previously-assumed numbers would have enormous cost implications for central and
local Government
Ÿ
A
year-2000 report for the UK Mental Health Foundation by Professor Martin Knapp
for the UK Institute of Psychiatry used the earlier “textbook” rate of
autism of 5/10,000 to put the total UK economic cost of autism at £1bn. The
Knapp report estimated the lifetime cost of a severely-affected child at £3m,
for a high-functioning autism child at £0.8m, and for an Asperger’s syndrome
child at £0.5m. The revised £5bn per year estimate is based upon these costs.
13. University of Sunderland Research
An
unpublished study by the UK University of Sunderland found a tenfold increase in
diagnosis of autism, during the years 1989-93. Further details are awaited.
14. UK National Autistic Society Estimates
The
NAS issued a factsheet in early 1997 which gave the following prevalence rates:
Ÿ
People
with Kanner syndrome (IQ less than 70)
5/10,000, or 1 in 2,000
Ÿ
Other
spectrum disorders (IQ less than 70)
15/10,000, or 1 in 666
Ÿ
Asperger’s
(IQ 70 or above)
36/10,000, or 1 in 278
Ÿ
Other
spectrum disorders (IQ 70 or above)
35/10,000, or 1 in 286
Combined
total of above four groups
91/10,000, or 1 in 110
The
above implies a very high level of autism in the UK, and the
previously-described studies seem to bear this out.
The
NAS reach its 91 in 10,000 or 1 in 110 rate by taking the Wing & Gould study
(Camberwell, London) of 1979, which looked at children with an IQ of under 70
and found a rate of 20 per 10,000, and adding this to the study by Ehlers &
Gillberg (Sweden) of 1993 which looked at autistic children with an IQ of over
70 and found a rate of 71 per 10,000 (1 in 141).
The
91/10,000 rate is thus “merged data”, collected in two different countries
and some years apart, and thus needs to be treated with caution, particularly if
rates have since been rising further. The Wing & Gould study is now over two
decades out of date, and also pre-dates MMR introduction into the UK.
15. Report by Fiona Loynes, UK All-Party
Parliamentary Group on Autism, Dec. 2001
The
purposes of this report included:
Ÿ
To
establish numbers of children with autistic spectrum disorders
Ÿ
To
learn whether UK local education authorities believed there had been a recent
increase in the last five years
Ÿ
To
ascertain whether LEAs routinely collected data
The
findings included the following:
Ÿ
100
out of 115 LEAs reported an increase in autism in the past five years. Some
reported small increases, others reported far higher increases, in one case by
77%.
Ÿ
The
study compared the expected prevalence rate of all autistic spectrum disorders
in each LEA (91 in 10,000 or 1 in 110) with the actual recorded number of
children with ASD and a Statement of Educational Needs (21 in 10,000 or 1 in
476). If the estimated numbers are correct, then the implication is that 75% of
children with autism do not become included in the Statement data, because they
have no Statement.
Ÿ
Only
44 out of the 100 LEAs reporting an increase had actual data. Some of these
reported dramatic increases, up to 400% in four years.
16. Report, “Autism In Schools
- Crisis or Challenge”,
National Autistic Society UK, May 2002
This
report was complied from the findings of a survey carried out in seven local
education authorities across England, Wales and Scotland, although the Scottish
findings were reported separately. The England and Wales survey involved 373
individual surveys, with a response rate of over 30%, covering a pupil
population of 133,000. The study found that:
Ÿ
1
in 86 children in mainstream schools had special educational needs that were
related to ASD.
Ÿ
The
rate of ASD is three times higher in primary than in secondary schools. In
primary it is 1 in 80, in secondary it is 1 in 268.
Ÿ
This
is in addition to children with ASD in special schools. In special schools, 1 in
3 children has ASD-related needs.
17. Autism In Scottish Schools
Although
there is no proper UK database on autism, comparable to the US’s Individuals
With Disabilities Education Act (IDEA) database, and the Department for
Education and Employment does not have any breakdown of its total numbers of
children in England with special educational needs, the position is rather
better in Scotland. There, a Scottish Schools Census was implemented by the
Scottish Executive in 1998, and this annual survey gives a picture of rising
numbers within Scottish schools. The census covers both junior and senior
schools, and identifies (by sex) scholars with special educational needs,
counting those with a primary diagnosis of autism as “autistic” (they may
also have other disabilities). The data available is (totals):
|
year |
Number
of cases counted primarily as autism |
|
1998 |
820 |
|
1999 |
959 |
|
2000 |
1,245 |
|
2001 |
1,515 |
|
2002 |
2,204 |
|
2003 |
2,663 |
This
gives a rise over five successive years after 1998 of 225%. The criteria for
inclusion have not been changed during that time, and although greater awareness
and improved diagnosis may have made a minority contribution to the increase, it
seems inconceivable that there isn’t an underlying real increase in these
figures, matching the similar rises reported in the US by the IDEA database.
18. Is Autism Increasing?
- Some UK Pronouncements
These
are some recent, and sometimes self-contradicting, statements:
Ÿ
“There
is no good evidence that the frequency of autism has increased since the
introduction of MMR”
- Tessa Jowell, then Minister for Public Health, October 1997 (personal
communication to David Thrower)
Ÿ
“The
true incidence of autism is uncertain”
- Sir Kenneth Calman, then Chief Medical Officer, March 1998
Ÿ
The
apparent rise in autism in the UK began more than ten years before the
introduction of MMR”
- Tessa Jowell, in June 1998
Ÿ
“Rates
of autism are rising, but not because of MMR”
(Committee on Safety of Medicines, June 1999)
Ÿ
“There
is no robust data on the prevalence of autism before and after MMR’s
introduction”
- Brent Taylor, in a June 1999 study heavily quoted by the Department of Health
Ÿ
“Numbers
of cases of autism are rising, but the reason for this is unclear”
- John Hutton, Minister for Public Health, December 2000
Ÿ
“Methodological
differences between studies, changes in diagnostic practice and public and
professional awareness are likely causes of increases in prevalence. Whether
these factors are sufficient to account for increased numbers of identified
individuals, or whether there has been a rise in actual numbers, is as yet
unclear” - Medical Research Council 2001 review, quoted by the Scottish
Parliament Expert Group May 2002.
Ÿ
“Two
thirds of (surveyed) teachers felt that there were more children with ASD now
than five years ago. This (is) consistent across age groups and in all types of
education provision, special and mainstream”
(Report of the National Autistic Society, May 2002)
Ÿ
“The
vast majority of the increase is due to the fact that we’re much better at
detecting autism now (and) we include many more things in the spectrum for
autistic spectrum disorders.....There’s a far wider spectrum, so that’s one
of the factors.”
- Dr. Stephen Ladyman, Health Minister for England, in Epolitix, 14th October
2003
But
then Dr. Ladyman hedged his bets a little.....
Ÿ
“And
underlying that, I think there may well be some sort of underlying increase in
the number as well.....But what I am as certain of as I can be is that it has
nothing to do with MMR and there is no reliable piece of science that links MMR
and autism.”
and
Ÿ
“In my view, it is clear from the
literature available that more people with autism have bowel disorders compared
to the rest of the population” (extract from All Party Parliamentary Group On
Autism minutes, address by the Minister).
19. Autism
In The USA
The
UK Department of Health is fond of saying how MMR is safely used in 32
countries, including the USA, as though its use elsewhere is proof, in itself,
that it is safe. Recent claims have even referred to 100 countries. A similar
attitude prevails over thimerosal.
But
the USA, at least, has clear evidence of an autism epidemic. Other countries may
also be becoming aware of increases, for example Finland, where a 400% increase
in cases has been alleged since was MMR introduced.
The
US has IDEA (Individuals with Disabilities Education Act). The Act was passed in
1975 to ensure equal educational opportunities for children with disabilities.
The US Department of Education is mandated to report annually to Congress.
Initially, autism cases were few, but in 1991 it was decided to specifically
list autism separately. Numbers were (US-wide) 5,415 in 1991-92.
This
system therefore picks up numbers of schoolchildren with developmental problems,
and illustrates a huge increase in autism numbers in a very short space of time.
Autistic pupils ages 6-21 have now increased from 5,415 in 1991-92 to 140,920 in
2003-2004 (Source: US IDEA State data). Thus for every case there was in the
IDEA system in 1991-92, there were 26 cases by 2004.
Since
the introduction of the more restrictive DSM-IV criteria from 1994 onwards, the
rise in US numbers has continued unabated:

140,920 |
(source:
Individuals With Disabilities Education Act)
Ÿ
To
the above total also has to be added the further cases of autism amongst
children aged 3-5 years. As at year 2000, this was 15,581 (this number will have
since increased further).
Ÿ
There
were huge increases in some States between 1992-1993 and 2002-2003
- up 968% in Connecticut,
779% in Florida, 1,131% (repeat: one thousand one hundred and thirty-one per
cent) in Idaho, 1,086% in Kansas, 1,291% in Minnesota, all in just ten years
(Source: US State data, Individuals with Disabilities Education Act). The rises
have continued into 2004.
Ÿ
Many
of the increases in individual States can only be described as alarming.

It
is also interesting that individual towns such as Round Rock, Texas, are
reported to be up from 6 cases to 115 cases in eight years
- very much like Wakefield
Local Education Authority in West Yorkshire UK (up from 5 to 111 in seven
years). This suggests that UK increases may very closely match those in the USA.
Ÿ
It
has been alleged that Brick Township (New Jersey) has manifested an “autism
cluster”. Some 40 of Brick Township’s 6,000 3-10 year olds have autistic
spectrum disorder. It has made Brick Township the “autism capital of the
USA” (but note, East Surrey rates in the UK are higher still). In Brick
Township, Federal investigators collected data on surface and ground water,
sites of industrial spillages and waste dumping, and also ensured that there had
been correct diagnosis of the actual children. They have found nothing untoward.
Their findings were reported in April 2000.
