Gary Kubiak Had A "Mini-Stroke" Sunday Night The medical term for what happened to Gary Kubiak at halftime last night is a transient ischemic attack, or TIA. The difference between a TIA and an ischemic stroke is that the obstruction and symptoms are temporary (or transient) as opposed to a true stroke where an obstruction in a blood vessel to the brain causes permanent neurological and/or motor deficits. That's the only difference, though, and this is clearly a concern for Kubiak.

According to the American Heart Association, one third of those who suffer a TIA will go on to have a stroke within one year. TIA's are generally quick and since the obstruction is temporary the likelihood of permanent injury to the brain is very low and recovery can be very quick. But they do serve as a warning for the potentially more severe stroke in the future.

According to Ian Rapoport, the Texans remain optimistic Kubiak will make a full recovery.
