1. What is a stroke?

Strokes are generally divided into three types: ischemic stroke, hemorrhagic stroke, and transient ischemic stroke. An ischemic stroke occurs when a blood clot forms in an artery, obstructing blood flow, or when the blood vessel wall thickens, reducing blood flow. A hemorrhagic stroke occurs when bleeding within the brain or subarachnoid hemorrhage affects blood circulation to the brain. Transient ischemic stroke, commonly known as a "mini-stroke," typically lasts from a few minutes to a few hours and resolves within 24 hours.
