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.
In aging, degradation of white matter structure has emerged as an important general factor, further focusing attention on the critical white matter connections. [citation needed] Exercise affects many people young and old. [14] For the young, if exercise is introduced it can form a constructive habit that can be instilled throughout adulthood.
The white matter is substantially affected, with noticeable atrophy (tissue loss), in addition to calcification of the arteries. [2] [6] [17] Microinfarcts may also be present in the gray matter (cerebral cortex), sometimes in large numbers. [2]
Also known as “sundowner’s syndrome,” sundowning is a set of symptoms or behaviors that can be seen in some people with Alzheimer’s disease and dementia, according to the Alzheimer’s ...
Researchers analyzing the white matter of superagers over a 5-year period found that despite comparable overall white matter health with typical older adults, superagers exhibited superior ...
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
