What happens during a transient ischemic attack?

During a transient ischemic attack (TIA), blood flow to the brain is temporarily reduced, leading to brief neurologic dysfunction. This disruption in blood flow often lasts only a few minutes, and while the symptoms may mimic those of a stroke, they do not result in permanent damage. The key aspect of a TIA is that it is a temporary condition, usually resolving within 24 hours without lasting effects. Recognizing a TIA is important because it serves as a warning sign of potential future strokes, prompting serious medical evaluation and intervention.
