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.
Different underlying brain dysfunctions have been hypothesized to result in the common symptoms of autism, just as completely different brain types result in intellectual disability. [1] [5] In recent years, the prevalence and number of people diagnosed with the disorder have increased dramatically. There are many potential reasons for this ...
The theory argues that characteristics and experiences of autistic and non-autistic people are so different that it is hard for one to understand how the other thinks and empathize with each other; for example, non-autistic people may not understand when an autistic person is overwhelmed. [142]
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]
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 revolutionized the understanding of autism and its connection to the brain. Different releases of the book came with alternative subtitles, including Exploring the Strength of a Different ...
Another goal of the use of rodent models to study autism is to identify the mechanism by which autism develops in humans. [1] Other researchers have developed an autism severity score to measure the degree of severity of the mice's autism, as well as the use of scent marking behavior [21] and vocalization distress [14] as models for communication.
