Warning Sign & Diagnosis

Your physician may identify certain signs that indicate you are at risk for stroke. Or, your body may warn you by the appearance of one or more of the symptoms listed on the following page. Familiarize yourself with the following important warnings. 

1.  Sudden weakness, numbness or paralysis of the face, arm or leg (especially on one side of the body)  Loss of speech or trouble talking or understanding language 

 2.Sudden loss of vision, particularly in only one eye 

3. Sudden, severe headache with no apparent cause 

 4.Unexplained dizziness, loss of balance or coordination (especially if associated with any of the above symptoms)

Transient Ischemic Attacks (TIAs)

About one-third of all strokes are preceded by one or more "mini-strokes," known as transient ischemic attacks (TIAs). TIAs can occur days, weeks or even months before a stroke.

TIAs are caused by temporary interruptions in the blood supply to the brain. The symptoms occur rapidly and last a relatively short time, usually from a few minutes to several hours, always with complete recovery within 24 hours. For instance, if you experience a sudden loss of vision, or weakness in an arm or leg that disappears, you might be having a TIA.

Because TIAs are temporary and the body soon returns to normal, it is easy to ignore them or to believe that the problem has disappeared. However, it is dangerous to ignore TIAs, because the underlying problem that caused the TIA continues to exist. TIAs are often early warning signs of more serious and debilitating stroke in the future.
