A transient ischemic attack (spelled ischaemic in British English) (abbreviated as TIA, often colloquially referred to as “mini stroke”) is caused by the changes in the blood supply to a particular area of the brain, resulting in brief neurologic dysfunction that persists, by definition, for less than 24 hours; if symptoms persist longer, then it is categorized as a stroke.

A transient ischemic attack (spelled ischaemic in British English) (abbreviated as TIA, often colloquially referred to as “mini stroke”) is caused by the changes in the blood supply to a particular area of the brain, resulting in brief neurologic dysfunction that persists, by definition, for less than 24 hours; if symptoms persist longer, then it is categorized as a stroke.
A cerebral infarct that lasts longer than 24 hours, but less than 72 hours is termed a reversible ischemic neurologic deficit or RIND.
Symptoms vary widely from person to person, depending on the area of the brain involved. The most frequent symptoms include temporary loss of vision (typically amaurosis fugax); difficulty speaking (aphasia); weakness on one side of the body (hemiparesis); and numbness or tingling (paresthesia), usually on one side of the body. Impairment of consciousness is very uncommon. There have been cases where there has been a temporary paralysis of a part of the face and the tongue.
