The amygdala, cerebellum, and many other brain regions have been implicated in autism. [15]Unlike some brain disorders which have clear molecular hallmarks that can be observed in every affected individual, such as Alzheimer's disease or Parkinson's disease, autism does not have a unifying mechanism at the molecular, cellular, or systems level.
Autism spectrum disorder [a] (ASD), or simply autism, is a neurodevelopmental disorder "characterized by persistent deficits in social communication and social interaction across multiple contexts" and "restricted, repetitive patterns of behavior, interests, or activities". [11] Sensory abnormalities are also included in the diagnostic manuals ...
The Autistic Brain: Thinking Across the Spectrum is a 2013 nonfiction popular science book written by Temple Grandin and Richard Panek and published by Houghton Mifflin Harcourt. It discusses Grandin's life experiences as a person with autism from the early days of scientific research on the topic and how advances in technology have ...
Iryna Spodarenko / GettyWe’ve come a long way in our understanding of autism since it was first used as a clinical description in 1943. Scientists have identified some of the genes that seem to ...
Autistic people appear to have a local bias for visual information processing, that is, a preference for processing local features (details, parts) rather than global features (the whole). [33] One explanation for this local bias is that people with autism do not have the normal global precedence when looking at objects and scenes ...
Vitamin B12: The researchers found that, overall, B12 levels in the brain tissue of autistic children were three times lower than those of the brain tissue of children not affected by ASD. This lower-than-normal B12 profile persisted throughout life in the brain tissues of patients with autism. These deficiencies are not visible by conventional ...
The extreme male brain theory (EMB), put forward by Baron-Cohen [4] suggests that autistic brains show an exaggeration of the features associated with male brains. These are mainly size and connectivity with males generally having a larger brain with more white matter , leading to increased connectivity in each hemisphere. [ 4 ]
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.
