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.
Brain fog is a constellation of symptoms that include reduced cognition, inability to concentrate and multitask, as well as loss of short-and long-term memory. Brain fog can be present in patients with autism spectrum disorder (ASD). Its prevalence, however, remains unknown. [28]

Autism, or autism spectrum disorder [a] (ASD), is a neurodevelopmental disorder characterized by repetitive, restricted, and inflexible patterns of behavior, interests, and activities, as well as deficits in social communication and social interaction, and the presence of high or low sensory sensitivity.
Human brain in the coronal orientation. Amygdalae are shown in dark red. The amygdala (/ ə ˈ m ɪ ɡ d ə l ə /; pl.: amygdalae / ə ˈ m ɪ ɡ d ə l i,-l aɪ / or amygdalas; also corpus amygdaloideum; Latin from Greek, ἀμυγδαλή, amygdalē, 'almond', 'tonsil' [1]) is a paired nuclear complex present in the cerebral hemispheres of vertebrates.
Brain sections and how autism relates to them. Many causes of autism, including environmental and genetic factors, have been recognized or proposed, but understanding of the theory of causation of autism is incomplete. [1] Attempts have been made to incorporate the known genetic and environmental causes into a comprehensive causative framework. [2]
High-functioning autism (HFA) was historically an autism classification to describe a person who exhibited no intellectual disability but otherwise showed autistic traits, such as difficulty in social interaction and communication, as well as repetitive, restricted patterns of behavior. The term is often applied to autistic people who are ...
Classic autism, also known as childhood autism, autistic disorder, (early) infantile autism, infantile psychosis, Kanner's autism, Kanner's syndrome, or (formerly) just autism, is a neurodevelopmental condition first described by Leo Kanner in 1943. It is characterized by atypical and impaired development in social interaction and communication ...
