How long do the signs and symptoms of a transient ischemic attack (TIA) typically last?

Transient ischemic attacks (TIAs), often referred to as "mini-strokes," are characterized by temporary disruptions in blood flow to the brain, leading to stroke-like symptoms. The key aspect of TIAs is their duration; they typically resolve within a short period, generally less than 24 hours. Most commonly, symptoms may last anywhere from a few minutes to a couple of hours, but crucially, they do not persist for a full day.

The correct response emphasizes that while TIAs can exhibit symptoms akin to a stroke, the defining feature is their transient nature, allowing them to last for less than a day. This understanding differentiates TIAs from actual strokes, where symptoms tend to be more permanent. Recognizing the typical duration of TIA symptoms is critical in emergency situations, as it can influence how quickly medical intervention is sought and how one perceives the severity of the signs they are experiencing.
