What is the neurologic problem that arises from a disruption of blood flow?

A stroke, also known as a cerebrovascular accident (CVA), occurs when there is a disruption of blood flow to the brain, leading to cell death and subsequent neurological deficits. This interruption can result from a blockage in a blood vessel supplying the brain (ischemic stroke) or a rupture of a blood vessel causing bleeding (hemorrhagic stroke). The loss of blood flow means that brain cells do not receive the oxygen and nutrients they need, leading to dysfunction.

In contrast, while hemorrhage can refer to bleeding that may accompany a stroke, it does not specifically denote the neurological consequences of disrupted blood flow as clearly as stroke does. A concussion is a type of traumatic brain injury caused by impact or shaking, not by blood flow disruption. Syncope, or fainting, involves a temporary loss of consciousness often due to reduced blood flow to the brain, but it is not classified as a neurologic problem stemming from a blood flow disruption in the same way stroke is recognized.
