Autism is associated with several genetic disorders, [4] perhaps due to an overlap in genetic causes. [5] About 10–15% of autism cases have an identifiable Mendelian (single-gene) condition, chromosome abnormality, or other genetic syndrome, [6] a category referred to as syndromic autism.
The term "high-functioning autism" was used in a manner similar to Asperger syndrome, another outdated classification.The defining characteristic recognized by psychologists was a significant delay in the development of early speech and language skills, before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]
More specifically, prevalence estimates of catatonia among people with neurodevelopmental disorders (of which autism is one) have ranged from 6-20.2%, with the mean estimate falling at 9%; [1] similarly, in a recent meta-analysis of 12 studies of autistic catatonia, Vaquerizo-Serrano et al. suggest that catatonia is found in 10.4% of autistic ...
The Aspie world, as it is sometimes called, contains people with Asperger syndrome (AS) and high functioning autism (HFA), and can be linked to three historical trends: the emergence of AS and HFA as labels, the emergence of the disability rights movement, and the rise of the Internet. Autistic communities exist both online and offline; many ...
These variabilities have led to the exploration of the clinical and molecular convergence between Rett syndrome and autism. [60] Sleeping and language impairments, seizures, and developmental timing are common in both autism and Rett syndrome (RTT). Because of these phenotypic similarities, there has been research into the specific genetic ...
Mind-blindness is defined as a state where the ToM has not been developed in an individual. [1] According to the theory, non-autistic people can make automatic interpretations of events taking into consideration the mental states of people, their desires, and beliefs.
Autism cases spiked 175% among U.S. residents from 2011 to 2022. The rates climbed at a faster rate among young adults.

It is characterized by atypical and impaired development in social interaction and communication as well as restricted, repetitive behaviors, activities, and interests.
