Cerebral atrophy is a common feature of many of the diseases that affect the brain. [1] ... (amygdala, hippocampus, thalamus), the cerebellum, ...
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 ]
This is caused by progressive degeneration of neurons in several parts of the brain including the basal ganglia, inferior olivary nucleus, and cerebellum. MSA was first described in 1960 by Milton Shy and Glen Drager and was then known as Shy–Drager syndrome. [2]
Pontocerebellar hypoplasia (PCH) is a heterogeneous group of rare neurodegenerative disorders caused by genetic mutations and characterised by progressive atrophy of various parts of the brain such as the cerebellum or brainstem (particularly the pons). [1] Where known, these disorders are inherited in an autosomal recessive fashion. There is ...
Infantile cerebral and cerebellar atrophy with postnatal progressive microcephaly is a rare hereditary autosomal recessive malformation syndrome of the central nervous system characterized by profound motor delays and intellectual disabilities, progressive microcephaly, hypertonia, spasticity, clonus and epilepsy. MRI findings include severe ...
(Spinocerebellar degeneration is a rare inherited neurological disorder of the central nervous system characterized by the slow degeneration of certain areas of the brain. There are three forms of spinocerebellar degeneration: Types 1, 2, 3. Symptoms begin during adulthood.) [citation needed]
In those with cerebral atrophy, Purkinje cells, or the cerebellar output neurons, in the vermis are reduced in number by 43%. [8] This large reduction in Purkinje cells causes a decrease in high order cerebral cortex organization. The cerebellum is also responsible for refining crude motor output from the primary motor cortex.
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.
