Document Summary
Study of prevalence of autism within a speci c cohort (born in 1989). Shows that prevalence increases from ages 6 right up to age 15. Autism by de nition must have symptoms manifest by the age of 34 months. However, 5 years later, we change our criteria for tall to. That would dramatically alter the prevalence rates of. Diagnosis substitution: less people are diagnosed as retarded, more people are diagnosed as autistic. I"ve never seen an autistic adult before. -->they just haven"t been diagnosed. The category of autism didn"t exist when they were kids. Haven"t been real extensive studies on adults with autism, diagnosed or otherwise. It"s been shown that regions where the cdc has better data collection apparatus, autism prevalence rates are consistently higher. e. g. new. Jersey has 2% prevalence and alabama has . 4%. Perhaps, new jersey just has better services for autistic people, so it attracts more autistic people and/or is better able to collect data on autistic people.
