Definition
By Mayo Clinic staffA transient ischemic attack (TIA) is like a stroke, producing similar symptoms, but usually lasting only a few minutes and causing no permanent damage. Often called a mini stroke, a transient ischemic attack may be a warning. About 1 in 3 people who have a transient ischemic attack eventually has a stroke, with about half occurring within a year after the transient ischemic attack.
A transient ischemic attack can serve as both a warning and an opportunity — a warning of an impending stroke and an opportunity to take steps to prevent it.
