How long do symptoms of a TIA typically last?

Transient Ischemic Attacks (TIAs) are characterized by temporary episodes that mimic the symptoms of a stroke but resolve within a short period. The hallmark of a TIA is that symptoms, such as weakness, numbness, or difficulty speaking, are typically brief, lasting only a few minutes up to 24 hours. However, they usually do not last more than a few minutes to an hour.

The duration of symptoms being a few minutes aligns with the definition of a TIA as a temporary interruption of blood flow to the brain, which does not result in ongoing damage. Identifying TIA symptoms can be critical, as they often serve as a warning sign for potential future strokes.

In contrast, symptoms lasting an hour, for example, would suggest something more akin to a full-blown stroke rather than a TIA. Similarly, symptoms persisting for 24 hours would also indicate a significant event requiring immediate medical intervention, rather than a transient episode. Finally, symptoms persisting for a few days would suggest a different type of neurological condition altogether rather than a transient ischemic attack.
