In a TIA, the symptoms disappear completely within a few hours, leaving no adverse effects. A stroke, on the other hand, can cause lasting, debilitating damage. Melvin Wichter, M.D., a neurologist at Advocate's Christ Hospital and Medical Center in Oak Lawn, equates TIAs with angina, chest pains that may signal a coming heart attack. But that risk can be reduced by seeking medical help when a TIA strikes. A TIA offers an incredible opportunity to prevent a future life-threatening event.
Prevention requires working with doctors to improve blood supply to the brain.
Common treatment includes aspirin and anticoagulants, which reduce the blood's tendency to clot. In some cases, surgery to remove plaque from arteries may be necessary.
