Some people have mild strokes or “mini-strokes.” This is when there is a temporary blockage to a blood vessel in a person’s brain. If the symptoms go away after a few hours, it is called a transient ischemic attack (TIA). The symptoms are similar to a regular stroke, but tend to be more minor and temporary. This is still a serious condition and may be an indication that a person is at risk for a more serious stroke. If you or someone you are with is experiencing symptoms of a stroke (loss of muscle tone or paralysis on one side, slurred or confused speech, sudden blindness, confusion, and/or severe headache), call 911 (or the emergency number in your area).
