Stroke occurs when blood supply to brain is reduced or restricted. The brain cells die due to lack of oxygen, nutrients and a blood vessel within the brain bursts. Strokes need to be diagnosed and treated as quickly as possible to minimize brain damage. There are three main types of strokes.
1. Transient ischemic attacks (TIAs): caused by blood clots or other clots.
