A third kind of stroke is known as transient ischemic attacks, TIAs or mini-strokes. TIAs are harder to spot than full-on strokes, but the damage they cause can accumulate. They are also a warning sign. People who have them are at higher risk of having a stroke. A TIA should not be ignored; seek medical care.

Howe's family hasn't said which type of stroke he had.

But the window in which the treatment works is small -- three hours for most patients, 4.5 hours for some others. So getting to hospital quickly is critical.
