Publisher's Synopsis
Transient ischemic attack, or TIA, is a potentially life-threatening condition caused by an obstruction to blood flow to the brain. TIA can affect anyone but is more common in older adults. The most common cause of TIA is a blood clot in an artery in the leg. TIA can also be caused by an irregular heart rhythm, a stroke, or a head injury.
Most TIA symptoms pass within a few hours, but occasionally they can last for a day or longer. If you experience any of the following symptoms, call your doctor right away: Fuzziness or difficulty speaking Seizures Memory problems Numbness or tingling in the arm or leg If you have a TIA, you should stay as still as possible and avoid any activity that might cause further injury to the brain. If you have a TIA, you may need to see a doctor to have a scan or an MRI to determine the cause and extent of the obstruction.
