A brain stroke, also known as a cerebrovascular accident (CVA), is a medical emergency that occurs when the blood supply to the brain is disrupted. This can result in brain damage and a range of physical, cognitive, and emotional symptoms. In this article, we’ll explore the causes, symptoms, treatment, and prevention of brain stroke.
Causes of Brain Stroke
The most common cause of brain stroke is a blockage or rupture of a blood vessel in the brain. This can be caused by:
- Atherosclerosis (narrowing of the arteries)
- High blood pressure
- Blood clots
- Aneurysms (weakness in the blood vessel wall)
- Arteriovenous malformations (AVMs) – abnormal tangles of blood vessels
