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 ...

[310] [311] [48] Wing summarised Asperger's autism syndrome, and made two challenges to points he had made. She also provided six case studies of her own, and much additional ...
Asperger's 1940 work, Autistic psychopathy in childhood, [9] found that four of the 200 children studied [10] had difficulty with integrating themselves socially. Although their intelligence levels appeared normal, the children lacked nonverbal communication skills, failed to demonstrate empathy with their peers, and were physically clumsy.
The term "high-functioning autism" was used in a manner similar to Asperger syndrome, another outdated classification.The defining characteristic recognized by psychologists was a significant delay in the development of early speech and language skills, before the age of three years. [12]

Sex and gender differences in autism exist regarding prevalence, presentation, and diagnosis.. Men and boys are more frequently diagnosed with autism than women and girls. It is debated whether this is due to a sex difference in rates of autism spectrum disorders (ASD) or whether females are underdiagnosed.
Classic autism, also known as childhood autism, autistic disorder, or Kanner's syndrome, is a formerly diagnosed neurodevelopmental disorder first described by Leo Kanner in 1943. It is characterized by atypical and impaired development in social interaction and communication as well as restricted, repetitive behaviors, activities, and interests.
