Transient ischemic attack (TIA)
Transient ischemic attack (TIA) refers to an interruption of blood flow to the brain; often an early warning sign of stroke.
Moreover, it is a temporary (transient) lack of oxygen (ischemia) to the brain, which may cause a time-limited set of neuropsychological deficits. TIAs are technically not considered a stroke, because neuronal death typically does not occur.
