How long do the symptoms of a transient ischemic attack typically last?

The symptoms of a transient ischemic attack (TIA) are described as temporary episodes of neurological dysfunction caused by a lack of blood flow to the brain. The defining characteristic of a TIA is that its symptoms typically resolve within a short period, generally no longer than one hour. This brief duration distinguishes a TIA from a stroke, which leads to prolonged symptoms and potentially permanent damage. The understanding of TIAs is crucial in emergency medicine, as they serve as a warning sign for potential future strokes, allowing for timely medical intervention.

The other options present durations that exceed the typical one-hour mark. While some symptoms can last longer in individual cases, they don't align with the medical definition of a TIA, where the symptoms specifically resolve quickly and the event is temporary.
