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.
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 ...
Clinically significant symptoms of these two conditions commonly co-occur, and children with both sets of symptoms may respond poorly to standard ADHD treatments. Individuals with autism spectrum disorder may benefit from additional types of medications. [13] [14] The term 'AuDHD' is sometimes used for those with both autism and ADHD.
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.
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 ...
This development section covers changes in brain structure over time. It includes both the normal development of the human brain from infant to adult and genetic and evolutionary changes over many generations. Neural development in humans; Neuroplasticity – changes in a brain due to behavior, environment, aging, injury etc.
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.
Both the mood symptoms and cognitive symptoms arise from the same underlying issue — a brain that isn’t in great health. And the mood symptoms and the cognitive symptoms seem to reinforce each ...
