Transient Ischemic Attack (Mini-Stroke) - eMedicineHealth

Stroke vs. Transient Ischemic Attack (TIA) Symptoms and Signs. Stroke or "brain attack" is similar to a heart attack, except that it only occurs in the brain. A transient ischemic attack (TIA, mini-stroke) is a type of stroke, but in a mini-stroke, the blood supply to the brain usually is restored, and sign and symptoms go away within minutes.
