Syndromic autism refers to cases where ASD is one of the characteristics associated with a broader medical condition or syndrome, representing about 25% of ASD cases. The causes of syndromic autism are often known, and monogenic ...
A 2003 review of epidemiological studies of children found autism rates ranging from 0.03 to 4.84 per 1,000, with the ratio of autism to Asperger syndrome ranging from 1.5:1 to 16:1; [142] combining the geometric mean ratio of 5:1 with a conservative prevalence estimate for autism of 1.3 per 1,000 suggests indirectly that the prevalence of AS ...

The professorship is made even more remarkable because when Arday was 3 years old, doctors diagnosed him with autism spectrum disorder and developmental delays. He didn’t begin to read or write ...
The scientific study of the causes of developmental disorders involves many theories. Some of the major differences between these theories involves whether environment disrupts normal development, if abnormalities are pre-determined, or if they are products of human evolutionary history which become disorders in modern environments (see evolutionary psychiatry).

Autism diagnoses have increased in the past decade. But that has largely as a result of diagnostic criteria expanding throughout the 1980s and 1990s. In 2013, numerous types of diagnoses were ...
