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.
Posterior reversible encephalopathy syndrome (PRES), also known as reversible posterior leukoencephalopathy syndrome (RPLS), is a rare condition in which parts of the brain are affected by swelling, usually as a result of an underlying cause.
Atrophy is the partial or complete wasting away of a part of the body. Causes of atrophy include mutations (which can destroy the gene to build up the organ), poor nourishment, poor circulation, loss of hormonal support, loss of nerve supply to the target organ, excessive amount of apoptosis of cells, and disuse or lack of exercise or disease intrinsic to the tissue itself.
General paresis, also known as general paralysis of the insane (GPI), paralytic dementia, or syphilitic paresis is a severe neuropsychiatric disorder, classified as an organic mental disorder, and is caused by late-stage syphilis and the chronic meningoencephalitis and cerebral atrophy that are associated with this late stage of the disease when left untreated.
In multiple system atrophy, autonomic dysfunction appears earlier and is more severe, [39] and is accompanied by uncoordinated movements, while visual hallucinations and fluctuating cognition are less common than in DLB. [153] Urinary difficulty is one of the earliest symptoms with multiple system atrophy, and is often severe. [70]
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]
The Brain Aneurysm Foundation reports that 1 in 50 people in the U.S. has an unruptured or intact aneurysm (an aneurysm in the brain that is not bleeding). However, the annual rate of an aneurysm ...
Korsakoff syndrome (KS) [1] is a disorder of the central nervous system characterized by amnesia, deficits in explicit memory, and confabulation.This neurological disorder is caused by a deficiency of thiamine (vitamin B 1) in the brain, and it is typically associated with and exacerbated by the prolonged, excessive ingestion of alcohol.
