Cerebellar degeneration is a condition in which cerebellar cells, otherwise known as neurons, become damaged and progressively weaken in the cerebellum. [1] There are two types of cerebellar degeneration; paraneoplastic cerebellar degeneration , and alcoholic or nutritional cerebellar degeneration. [ 2 ]
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.
Lobes in this cortex are more closely associated with memory and in particular autobiographical memory. [15] The temporal lobes are also concerned with recognition memory. This is the capacity to identify an item as one that was recently encountered. [16] Recognition memory is widely viewed as consisting of two components, a familiarity ...
Dyschronometria, also called dyschronia, is a condition of cerebellar dysfunction in which an individual cannot accurately estimate the amount of time that has passed (i.e., distorted time perception). It is associated with cerebellar ataxia, [1] [2] when the cerebellum
The inherited neurological disorders Machado–Joseph disease, ataxia telangiectasia, and Friedreich's ataxia cause progressive neurodegeneration linked to cerebellar loss. [57] [65] Congenital brain malformations outside the cerebellum can, in turn, cause herniation of cerebellar tissue, as seen in some forms of Arnold–Chiari malformation. [73]
Calcium triggering in the cerebellum is a critical mechanism involved in long-term depression. Parallel fibre terminals and climbing fibres work together in a positive feedback loop for invoking high calcium release. [16] LTD is involved in predictive control exerted by cerebellar circuitry and cerebellar reserve. [17]
