Patients with cerebellar degeneration experience a progressive loss of nerve cells (Purkinje cells) throughout the cerebellum. As well as this, it is common to incur an elevated blood protein level and a high volume of lymph cells within the cerebrospinal fluid , resulting in swelling and enlargement of the brain.
Cerebral atrophy is a common feature of many of the diseases that affect the brain. [ 1] Atrophy of any tissue means a decrement in the size of the cell, which can be due to progressive loss of cytoplasmic proteins. In brain tissue, atrophy describes a loss of neurons and the connections between them. Brain atrophy can be classified into two ...
Anatomical terms of neuroanatomy. [ edit on Wikidata] The cerebellum ( pl.: cerebella or cerebellums; Latin for "little brain") is a major feature of the hindbrain of all vertebrates. Although usually smaller than the cerebrum, in some animals such as the mormyrid fishes it may be as large as it or even larger. [ 1]
Upper surface of cerebellum. The vermis is highlighted in red. Vermis (highlighted in red) on the cerebellum. The cerebellar vermis (from Latin vermis, "worm") is located in the medial, cortico-nuclear zone of the cerebellum, which is in the posterior fossa of the cranium. The primary fissure in the vermis curves ventrolaterally to the superior ...
Cerebellar hypoplasia is characterized by reduced cerebellar volume, even though cerebellar shape is (near) normal. It consists of a heterogeneous group of disorders of cerebellar maldevelopment presenting as early-onset non–progressive congenital ataxia, hypotonia and motor learning disability . Various causes have been identified, including ...
Age-related decrease in gray matter volume was the largest contribution to changes in brain volume. Moreover, neuronal density appears to decrease, white matter microstructure gets altered and energy metabolism in the cerebellum gets altered. [16] General cortical atrophy occurs in aging and e.g. the caudate nucleus volume appears to decrease.
Brain herniation is a potentially deadly side effect of very high pressure within the skull that occurs when a part of the brain is squeezed across structures within the skull. The brain can shift across such structures as the falx cerebri, the tentorium cerebelli, and even through the foramen magnum (the hole in the base of the skull through ...
Neurology. 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 ...
