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.
Subdural hygromas require two conditions in order to occur. First, there must be a separation in the layers of the Meninges of the brain. Second, the resulting subdural space that occurs from the separation of layers must remain uncompressed in order for CSF to accumulate in the subdural space, resulting in the hygroma. [1]
Alcohol-related brain damage [1] [2] alters both the structure and function of the brain as a result of the direct neurotoxic effects of alcohol intoxication or acute alcohol withdrawal. Increased alcohol intake is associated with damage to brain regions including the frontal lobe , [ 3 ] limbic system , and cerebellum , [ 4 ] with widespread ...
"Studies have shown that in adults who exercise regularly, there was a significantly reduced rate of brain tissue atrophy as well as signs of vascular tissue injury and silent stroke based on MRI ...
The most severe brain atrophy appears to be associated with behavioral variant FTD, and corticobasal degeneration. [42] With regard to the genetic defects that have been found, repeat expansion in the C9orf72 gene is considered a major contribution to FTLD, although defects in the GRN and MAPT genes are also associated with it.

“Alcohol can negatively impact the brain’s memory center known as the hippocampus by causing cell atrophy and by inhibiting the growth of new neurons via a process called neurogenesis.
People with high blood pressure who slept for shorter durations were more likely to show poor cognitive function and increased levels of markers of brain aging and injury, a new study has found.
A normal centenarian brain, cut in the coronal plane (top left) is compared to a brain with LATE-NC (top right). The hippocampi on both sides are atrophic (shrunken) in the brain with LATE-NC. The bottom 3 panels show photomicrographs of a hippocampus with LATE-NC, stained for phosphorylated TDP-43 protein (TDP-43).
