TRANSIENT ISCHEMIC ATTACKS

Similar symptoms to those of a stroke are produced by transient ischemic attacks (TIAs), which typically persist for a few minutes and do not result in permanent damage.
A transient ischemic attack, often referred to as a ministroke, could be an alert. A stroke will eventually occur in around 1 in 3 persons who experience transient ischemic attacks, with about half of those strokes happening within a year after the transient ischemic attack.
A transient ischemic attack can alert one to the possibility of an approaching stroke and present a chance to take preventative action.
Symptoms
Attacks of transient ischemia often last a few minutes. The majority of symptoms and indicators go away after an hour. Similar to the initial stages of a stroke, transient ischemic attacks (TIAs) can cause sudden start of:
feeling weak, numb, or paralyzed in your arm, leg, or face; usually on one side of the body
speech that is slurred or garbled, or trouble comprehending others
double vision or blindness in one or both eyes
feeling lightheaded or uncoordinated
Depending on which part of the brain is affected, you may experience repeated signs and symptoms from many TIAs.
