Brain tissue damage resulting from impaired circulation of blood to the brain.
A sudden blocking of or bleeding from a blood vessel in the brain resulting in temporary or permanent paralysis or death.
Also referred to as a stroke; sudden circulatory impairment in the vasculature system of the brain.
Abnormal condition in which hemorrhage or blockage of the blood vessels of the brain leads to oxygen lack and resulting symptom sudden loss of ability to move a body part (as an arm or parts of the face) or to speak, paralysis, weakness, or, if severe, death. Usually only one side of the body is affected. Physical therapy and speech therapy can result in some degree of recovery.
Generalized term pertaining to all strokes without regard to the underlying pathology or mechanism.
Damage to the brain resulting from blockage or rupture of a cerebral artery, also called a stroke. A CVA may cause loss of consciousness, paralysis, or death, depending on its severity and location and the patient’s state of health.
The sudden rupture or blockage of a blood vessel within the brain, leading to acute neurological damage; commonly referred to as stroke. Cerebral infarctions, or thrombotic strokes, result from blockage caused by thrombosis (clot formation) or embolism (interruption of blood flow as a result of obstruction by a clot or plug of insoluble material carried in the bloodstream). An embolism usually results in a sudden onset of symptoms, while a thrombotic stroke usually begins more gradually. Hemorrhagic strokes are classified based on the pattern of bleeding. In a cerebral hemorrhage, bleeding occurs within the brain. In a subarachnoid hemorrhage, bleeding occurs around the brain. Despite their differences, hemorrhage, thrombosis, and embolism are also all commonly referred to as strokes when they occur in the brain.
The abrupt rupture or blockage of a blood vessel within the brain results in severe bleeding and/or the localized hindrance of blood flow. This condition, known as a stroke, occurs when the blood supply to a specific area of the brain is interrupted, leading to damage.
The blockage within blood vessels can occur due to either thrombosis, which is the formation of a clot, or embolism, which involves a fragment of a clot or an air bubble carried within the circulation. On the other hand, vessel rupture can result in distinct bleeding patterns, namely intracerebral hemorrhage, which refers to bleeding within the brain, or subarachnoid hemorrhage, which involves bleeding around the brain.
