Transient ischemic attacks usually last a few minutes. Most signs and symptoms disappear within an hour. The signs and symptoms of TIA resemble those found early in a stroke and may include sudden onset of:
- Weakness, numbness or paralysis in your face, arm or leg, typically on one side of your body
- Slurred or garbled speech or difficulty understanding others
- Blindness in one or both eyes or double vision
- Dizziness or loss of balance or coordination
You may have more than one TIA, and the recurrent signs and symptoms may be similar or different depending on which area of the brain is involved.
When to see a doctor
Seek immediate medical attention if you suspect you've had a transient ischemic attack. Prompt evaluation and identification of potentially treatable conditions may help you prevent a stroke.
