Cerebellar cognitive affective syndrome (CCAS), also called Schmahmann's syndrome [1] is a condition that follows from lesions (damage) to the cerebellum of the brain. It refers to a constellation of deficits in the cognitive domains of executive function, spatial cognition, language, and affect resulting from damage to the cerebellum.
These disorders prevail when T-cells (also known as white blood cells) begin to harm familiar cells in the central nervous system rather than the cancerous cells, [2] resulting in degeneration of neurons in the cerebellum. Other signs and symptoms that commonly result from the incursion of a paraneoplastic disorder include an impaired ability ...
Common signs of dyschronometria are often generic to cerebellar ataxia, including a lack of spatial awareness, poor short term memory, and inability to keep track of time. [citation needed] [5] The defining symptoms, while not completely understood, involve time perception. For example, when asked to wait for thirty seconds, or tap every second ...
They show that either the development of the cerebellum is tightly linked to that of the rest of the brain or that neural activities taking place in the cerebellum were important during Hominidae evolution. Due to the cerebellum's role in cognitive functions, the increase in its size may have played a role in cognitive expansion. [85]
The development of memory is a lifelong process that continues through adulthood. Development etymologically refers to a progressive unfolding. Memory development tends to focus on periods of infancy, toddlers, children, and adolescents, yet the developmental progression of memory in adults and older adults is also circumscribed under the umbrella of memory development.
The cerebellum is the brain's main control center for planning, adjusting, and executing movements of the body, the limbs and the eyes. It plays a major role in several forms of motor learning, including balance and posture. [3] In the past, the evidence for a role for the cerebellum in cognitive functions was rather weak. [4]
Dystonia is a multifaceted disorder that stems from cerebellar dysfunction, and it is marked by the development of uncontrollable muscle contractions. [30] The capacity to restore functional cerebellar processing after impairments suggests NICS as a potential treatment to aid in the control of these symptoms within certain patients. [30]
The scientific study of the causes of developmental disorders involves many theories. Some of the major differences between these theories involves whether environment disrupts normal development, if abnormalities are pre-determined, or if they are products of human evolutionary history which become disorders in modern environments (see evolutionary psychiatry).
