What does chronic micro vascular ischemic changes are demonstrated throughout bihemispheric white matter on a mri?

Microvascular change: This is very common in the older population. The blood vessels get narrower/ a bit clogged/clotted from the aging /diet/ lifestyle process-if very severe could be associated with dementia but it is common in older people . The white matter are the axons of the nerve cells ( the "legs" -relay /conduction part ) and connect to the grey matter- neurons (the " brain"). Dont worry.
