Among individuals with TS studied in clinics, between 2.9% and 20% had autism spectrum disorders, [59] but one study indicates that a high association of autism and TS may be partly due to difficulties distinguishing between tics and tic-like behaviors or OCD symptoms seen in people with autism. [60] Not all people with Tourette's have ADHD or ...
The pathophysiology of autism is the study of the physiological processes that cause or are otherwise associated with autism spectrum disorders . Autism's symptoms result from maturation-related changes in various systems of the brain. [1] How autism occurs is not yet well understood. Its mechanism can be divided into two areas: the ...
Autistic catatonia is a term used to describe the occurrence of catatonia in autistic people. [1] Catatonia occurs in roughly 10 percent of people diagnosed with an autism spectrum disorder.
