Warning Signs

Call 911 if you notice the sudden appearance of any of these symptoms:

• Numbness or weakness in the face, arms or legs, often on only one side of the body
• Trouble speaking or understanding what others are saying
• Vision: Problems seeing with one or both eyes, or sudden double vision
• Dizziness: Loss of balance or dizziness
• Trouble walking: Problems with movement or walking
• Severe headache that comes on suddenly with no known cause

Do not ignore any of the warning signs, even if they go away - take action immediately. Always consult your physician for a diagnosis.

Other symptoms of stroke:

• sudden nausea, vomiting, or fever not caused by a viral illness
• brief loss or change of consciousness such as fainting, confusion, seizures, or coma
• transient ischemic attack (TIA), or "mini-stroke"

A TIA can cause many of the same symptoms as a stroke, but TIA symptoms can last for a few minutes or up to 24 hours. Call for medical help immediately if you suspect a person is having a TIA, as it may be a warning sign that a stroke is about to occur. Not all strokes, however, are preceded by TIAs.
