What is the major complication associated with a TIA? In a transient ischemic attack, the blockage usually dissolves, and the symptoms clear within an hour. However, in an ischemic stroke the blockage remains long enough to cause significant damage to the brain, long-term disability and may possibly even be fatal.
What damage does a TIA cause? Like a stroke, a TIA occurs when a blockage in a blood vessel stops the flow of blood to part of the brain. Unlike a stroke, TIA symptoms do not persist and resolve within 24 hours – and often much faster. A TIA doesn’t leave any permanent brain damage or cause lasting neurologic problems.
What are the complications of ischemic stroke? Patients with acute ischemic stroke are at high risk of neurologic and medical complications, such as space-occupying edema formation, hemorrhagic transformation of the infarct, epileptic seizures, depression, and venous thromboembolism.
What happens during a transient ischemic attack? A transient ischemic attack (TIA) happens when blood flow to part of the brain is blocked or reduced, often by a blood clot. After a short time, blood flows again and the symptoms go away. With a stroke, the blood flow stays blocked, and the brain has permanent damage.
