A transient ischemic attack (TIA), also known as a minor ischemic stroke, is a brief episode of neurological dysfunction caused by focal brain, spinal cord, or retinal ischemia without acute infarction. TIAs are caused by transient blockages in the blood vessels that supply the brain, usually from atherosclerotic plaques or blood clots. Symptoms of TIAs, which typically last less than 5 minutes, can include unilateral weakness or numbness, speech impairment, or vision issues.
