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 ...
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 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 folds of autistic human brains are found to experience slight shifts in location, early in brain development. Specifically, different patterns appear in the superior frontal sulcus, Sylvian fissure, inferior frontal gyrus, superior temporal gyrus, and olfactory sulci. [ 45 ]
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 ...
They've used genetic engineering to breed over a dozen macaque monkeys with a flawed gene that triggers a rare form of autism in humans. The hope is that researchers can not only study how brains ...
It has been found that there are significant differences in brain activation in self and other situations in autistic children when compared to children who do not have autism. In adults who do not have autism, during self-recognition tasks, the inferior frontal gyrus and the inferior parietal lobule in the right hemisphere are activated ...
