A transient ischemic attack (TIA) is a temporary period of symptoms similar to those of a stroke. It occurs when there is a temporary decrease in blood flow to a part of the brain, often due to a blood clot. Symptoms can include sudden weakness, numbness, or difficulty speaking, but they typically resolve within a few minutes to hours. Although TIAs do not cause permanent damage, they are serious warning signs of a potential future stroke. Individuals experiencing a TIA should seek medical attention immediately, as prompt treatment can help prevent a more severe stroke later on.
