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.
Autistic people, including those with Asperger's, have more sparse (or inactive) wiring in some of the areas where neurotypicals are heavily wired, and more intense (or more active)—sometimes much more intense—wiring in different areas. If the "activity" of the circuits in some areas of neurotypical brains are temporarily reduced, they ...
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 ...
Autistic people struggle to understand the social context and subtext of neurotypical conversational or printed situations, and form different conclusions about the content. [110] Autistic people may not control the volume of their voice in different social settings. [111] At least half of autistic children have atypical prosody. [111]
The physical underpinnings of the cause for differences in the memory of autistic people has been studied. Bachevalier suggests a major dysfunction in the brain of an autistic individual resides in the neural mechanisms of the structures in the medial temporal lobe (MTL) and perhaps, more specifically the amygdaloid complex. [46]
The following chapters investigate the biological background of autism and how historically it was claimed to be either the result of direct brain damage or poor parenting and how the practice of diagnostic classification, or nosology, negatively impacted the understanding of children with autism and others on the spectrum.
A young boy with autism who has arranged his toys in a row. Several researchers have suggested a clinical link between difficulties in neural binding and autism spectrum disorders. [32] It has been postulated that there is a level of underconnectivity between certain areas of the autistic brain, specifically those areas that involve social ...
Mind-blindness is defined as a state where the ToM has not been developed in an individual. [1] According to the theory, neurotypical people can make automatic interpretations of events taking into consideration the mental states of people, their desires, and beliefs.
