Typically, microbleeds don't have short-term consequences on brain purpose, but after some time they can result in an increased chance of dementia and cognitive impairment. Massive hemorrhages, having said that, can come about When the Bodily stresses caused by really high blood pressure, speedy blood move prices, and vessel wall weak point are fantastic enough.
