Transient ischemic attack (TIA):

A transient ischemic attack (TIA) — sometimes known as a ministroke — is a temporary period of symptoms similar to that of had a stroke. A temporary decrease in blood supply to part of our brain causes TIAs, which may last as little as five minutes.

Like an ischemic stroke, a TIA occurs when a clot or debris blocks blood flow to part of your nervous system — but there is no permanent tissue damage and no lasting symptoms.

Seek emergency care even if the symptoms seem to clear up. Having a TIA puts anyone at greater risk of having a full-blown stroke, causing permanent damage later. If had a TIA, it means there's likely a partially blocked or narrowed artery leading to your brain or a clot source in the heart.

It's not possible to tell whether you are having a stroke or a TIA based only on your symptoms. Even when symptoms last for under an hour, there is still a risk of permanent tissue damage.
