Final answer:
A transient ischemic attack (TIA) is characterized by brief episodes of neurological dysfunction.
Step-by-step explanation:

A TIA is a temporary loss of neurological function caused by a brief interruption in blood flow to the brain. The symptoms of a TIA typically resolve within 24 hours and do not cause permanent neurological deficits.
