NAS has a definition on their site:
I’m sure there must be differences, however subtle, but to me it just looks like high functioning autism/aspergers etc by another name.

There are five distinct types of Pervasive Developmental Disorders (PDD) that are considered to be related to Autism because of the neuro development portions that have been identified under the Autism Spectrum. They are Autism Disorder, Asperger’s Syndrome, Rett’s Disorder, Childhood Disintegrative Disorder, and Pervasive Developmental Disorder Not Otherwise Specified. PDD is the umbrella term for all autistic and autistic like conditions. Someone with autism will have PDD but someone with PDD will not necessarily have autism. (PDDNOS). Classic Autism, commonly called Autism, is also sometimes called Kanner’s Syndrome after the Psychiatrist Leo Kanner. He studied 11 children at John Hopkins University from 1932 to 1943. He wrote about the common elements found in these children including a lack of emotion, repetitive actions, and problems with their speech formation, their ability to manipulate various objects, learning difficulties, and their levels of intelligence. Asperger’s Syndrome is named after its founder, Hans Asperger. His studies took place in Vienna in 1944. He discovered many individuals had the problems with social skills and repetitive patterns but they did not have trouble with learning or their cognitive abilities. They also portrayed some very exceptional talents or abilities that were considered to be very remarkable. Albert Einstein is a very famous individual who had Asperger’s Syndrome.Childhood Disintegrative Disorder (CDD) is also called Heller’s Syndrome after the teacher Theodore Heller. He first described the disorder in 1908. The characteristics include the child having a normal pattern of development but then has a regression of skill as they get older. Rett syndrome is caused by a mutation in the sequence of a single gene. Loss of muscle control, resulting in problems in walking and eye movement, is the first visible sign of this disorder. Motor skills are severely hampered and interfere with every body movement, leading to the development of stereotyped and repetitive hand and leg movements. PDD/NOSAny type of neuro disability that doesn’t fall into the above categories is classified as PDDNOS. PDD/NOS this catogoriy is usally given when autistic traits are present but not enough to put a specific sectionThere is some confusion over the use of the diagnostic term PDD-NOS. This should only ever be applied where all other diagnostic terms have been discarded already.conditions covered by pervasive developmental disorder are autism,Rett's Disorder, Childhood Disintegrative Disorder, and Asperger's Disorder. An additional diagnosis, Pervasive Developmental Disorder, Not Otherwise Specified (NOS), is used to indicate PDDs of unknown origin. All of the pervasive developmental disorders are characterized by communication and social impairments. They are differentiated from one another on the basis of research suggesting different causes for the underlying impairments, and by different impairment profiles and intensities of impairment typical of each condition. Though autism spectrum disorders are synonymous with pervasive developmental disorders, a person can have a pervasive developmental disorder and not carry the diagnosis of autism in particular.all autistic spectrum disorders are PDDShttp://autismandaspergersinthefamily.freeforums.org/the-five-types-of-pdd-t900.html
