Word: Cerebrovascular Accident (CVA)
Definition: A cerebrovascular accident, commonly known as a stroke, is a sudden medical condition that occurs when the blood supply to part of the brain is interrupted or reduced. This can happen because a blood vessel is blocked (ischemic stroke) or because a blood vessel bursts (hemorrhagic stroke). This lack of blood flow can lead to the loss of consciousness or other serious health problems.
A cerebrovascular accident is a serious medical event that requires immediate attention. Being aware of the signs of a stroke (like sudden numbness or confusion) can be lifesaving.
