Brain shrinkage does accelerate when you’re older. Brain volume continues to decrease as we age—including the frontal lobe and hippocampus, the areas responsible for cognitive functions—with ...
Older adults can exhibit reduced activity in specific brain regions during cognitive tasks, particularly in medial temporal areas related to memory processing. On the other hand, overrecruitment of other brain areas, mainly in the prefrontal cortex, can be engaged in memory-related tasks. [10]
If older adults have fewer attentional resources than younger adults, we would expect that when two tasks must be carried out at the same time, older adults' performance will decline more than that of younger adults. However, a large review of studies on cognition and aging suggest that this hypothesis has not been wholly supported. [56]
A large study in China tracked middle-aged and older adults for 20 years, using regular brain scans, spinal taps and other tests. ... differences in brain shrinkage and cognitive test scores ...
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.

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. [43]
