Transient ischemic attack (TIA)

A transient ischemic attack (TIA) happens when blood flow to part of the brain is stopped for a short time. This can cause stroke symptoms that may last for at least a few minutes. But unlike a stroke, a TIA doesn't cause lasting brain damage.

A TIA is a warning that you may have a stroke in the future. Early treatment can help prevent a stroke.
