Transient ischemic attack (TIA)

Blood flow blocked to an area of the brain for a short time.

During a transient ischemic attack (TIA), blood flow to part of the brain is temporarily blocked or reduced, often by a blood clot. This causes the same symptoms as a stroke, but after a few minutes or more, blood flow is restored and the symptoms go away.
