Stroke

A stroke occurs when blood flow to the brain is interrupted (ischemic stroke) or when a blood vessel in the brain ruptures (hemorrhagic stroke). Both can cause the death of brain cells in the affected areas. Stroke is also considered a neurological disorder because of the many complications it causes. Other forms of cardiovascular disease, such as high blood pressure, increase your risk of stroke.

Symptoms of stroke

* Sudden numbness or weakness of the face, arm or leg (especially on one side of the body)
* Sudden confusion, trouble speaking or understanding speech
* Sudden trouble seeing in one or both eyes
* Sudden trouble walking, dizziness, loss of balance or coordination
* Sudden severe headache with no known cause

If you have any of these symptoms, you must get to a hospital quickly to begin treatment.
