Overview

  • This section covers:

    What is a stroke? A stroke results when blood and oxygen flow to the brain is stopped or interrupted.

    Causes and types of stroke: There are two types of stroke: ischemic and hemorrhagic.

    Transient ischemic attacks (TIAs): 'Mini-strokes' - In some cases, strokes are preceded by transient ischemic attacks (TIAs) or "mini-strokes."

    Risk factors and prevention: Risk factors increase your chance of having a stroke. Your doctor can help you determine your risk factors -- what you can and cannot control.

    Stroke warning signs: Call 911 - Stroke symptoms may last a short time and disappear. They are often present when you wake up.

    A stroke involves the brain (cerebral) and the blood vessels (vascular).
