A new study examines how age-related brain changes could be linked to stroke recovery. Researchers suggest areas of age-related damage to parts of the brain containing white matter may influence ...
Head CT showing periventricular white matter lesions. Leukoaraiosis is a particular abnormal change in appearance of white matter near the lateral ventricles. It is often seen in aged individuals, but sometimes in young adults. [1] [2] On MRI, leukoaraiosis changes appear as white matter hyperintensities (WMHs) in T2 FLAIR images.
The brain is very complex, and is composed of many different areas and types of tissue, or matter. The different functions of different tissues in the brain may be more or less susceptible to age-induced changes. [6] The brain matter can be broadly classified as either grey matter, or white matter.
Binswanger's disease, also known as subcortical leukoencephalopathy and subcortical arteriosclerotic encephalopathy, [1] is a form of small-vessel vascular dementia caused by damage to the white brain matter. [2] White matter atrophy can be caused by many circumstances including chronic hypertension as well as old age. [3]
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 ...
Silent strokes typically cause lesions which are detected via the use of neuroimaging such as MRI. [2] [3] The risk of silent stroke increases with age but may also affect younger adults. Women appear to be at increased risk for silent stroke, with hypertension and current cigarette smoking being amongst the predisposing factors. [2] [4]
Disconnection syndrome is a general term for a collection of neurological symptoms caused – via lesions to associational or commissural nerve fibres – by damage to the white matter axons of communication pathways in the cerebrum (not to be confused with the cerebellum), independent of any lesions to the cortex.

From the age of 60 years (10%) to the age of 80 years (60%), the proportion of people with senile plaques increases linearly. Women are slightly more likely to have plaques than are men. [ 45 ] [ 44 ] Both plaques and Alzheimer's disease also are more common in aging persons with trisomy -21 ( Down syndrome ).
