Warning Strokes: symptoms before they happen

ONTARIO (NBC) -- Many people who suffer a stroke may have had one before, but never knew they did.

Warning strokes, also known as TIA, are stroke symptoms that last for less than 24 hours and resolve on their own.

Researchers at the University of Western Ontario studided over 16,000 stroke cases.  They found 12 percent of patients had a warning stroke before suffering a stroke that landed them in the hospital.

They also found people who did not have a warning stroke were more likely to die at the hospital, or have a heart attack.

Diabetics and people with high blood pressure were more likely to suffer warning strokes. Experts say their already damaged blood vessels may have protected them from the full effects of stroke.
