Relating to the blood vessels of the brain and the blood flow through them.
From cerebro- (brain) and vascular (relating to blood vessels, from Latin vasculum meaning 'small vessel'). This medical term became standard as doctors studied strokes and brain blood flow in the 20th century.
Cerebrovascular disease is why strokes happen—when blood clots block the brain's blood vessels, brain cells starve of oxygen in minutes, and understanding this mechanism has been key to saving lives.
