A stroke occurs when the blood supply to a part of the brain is cut off and the brain cells in that part cannot function. The affected person may have:
1. Weakness or paralysis, usually on one side of the body, often with loss of feeling in the affected areas.
2. Difficulty in speaking or understanding
3. Difficulty in swallowing
4. Loss of concentration and memory
5. Loss of control of passing urine or passing motion
6. Behavior changes such as laughing or crying at the wrong time, feeling depressed or showing bad temper.
If the blood supply is cut off only for a very short time in a small part of the brain, the effects will be mild and temporary. If it is cut off for a long period, the effects will be more severe and longer lasting. In a few cases, a stroke can result in death.
