stroke patients

Time is one of the biggest factors in treating strokes — and a group of South Florida researchers say they’ve found a way to buy stroke patients more time.

If a person has a stroke, the sooner they get treatment, the better their odds are of surviving and of healing without permanent disability. Generally, the thinking has been that patients have a window of no more than six hours for a clot-removal surgery to be effective.

But people don’t always know when they’ve had a stroke — like if it happens while they’re sleeping. And that complicates treatment options.
