How long do symptoms of a transient ischemic attack (TIA) last?

Symptoms of a transient ischemic attack (TIA) typically last for a short duration, commonly resolving completely within 24 hours. A TIA is often characterized by temporary neurological deficits that result from a brief interruption of blood flow to the brain. The defining feature of a TIA is that these symptoms are transient, meaning they do not persist long enough to cause permanent damage to brain tissue. In most cases, the symptoms can last just a few minutes to a few hours, with full recovery occurring within 24 hours after onset. This rapid resolution is a critical distinction between a TIA and a stroke, where symptoms last longer and may lead to lasting disability or damage.
