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.
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.
The striatum (pl.: striata) or corpus striatum [5] is a cluster of interconnected nuclei that make up the largest structure of the subcortical basal ganglia. [6] The striatum is a critical component of the motor and reward systems; receives glutamatergic and dopaminergic inputs from different sources; and serves as the primary input to the rest of the basal ganglia.
Adults and children with ADHD show reduced anticorrelation between the DMN and other brain networks. [ 55 ] [ 56 ] The cause may be a lag in brain maturation. [ 57 ] More generally, competing activation between the DMN and other networks during memory encoding may result in poor long-term memory consolidation, which is a symptom of not only ...
Amygdala is shown in purple. The amygdalofugal pathway (Latin for "fleeing from the amygdala" and commonly distinguished as the ventral amygdalofugal pathway) is one of the three principal pathways by which fibers leave the amygdala. The other main efferent pathways from the amygdala are the stria terminalis and anterior commissure.
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. [31]
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 ...
Symptoms of a mild brain injury include headaches, confusions, tinnitus, fatigue, changes in sleep patterns, mood or behavior. Other symptoms include trouble with memory, concentration, attention or thinking. [3] Mental fatigue is a common debilitating experience and may not be linked by the patient to the original (minor) incident.
