The reduced blood supply starves brain cells of nutrients and over time they become damaged and die. Symptoms of vascular dementia include loss of energy, lack of concentration and poor memory.

• Mini-strokes or transient ischemic attacks occur when the blood supply to the brain is briefly interrupted. Symptoms of a TIA last less than 24 hours and, generally, no permanent damage occurs.

When blood supply is reduced, they release a chemical signal to nearby nerve cells that raise blood pressure, restoring blood flow to the brain,” added Julian Paton, PhD, co-author of the paper ...
