A mini-stroke is a transient ischemic attack, and the most common cause is a blood clot that temporarily blocks the blood supply to a part of the brain, according to WebMD. About one in three people with a mini-stroke eventually experience a real stroke, and immediate medical attention is an important part of intervention.
A variety of imaging tests are available that look at the brain and blood supply and help doctors determine the cause of a mini-stroke, notes WebMD. These include a Doppler ultrasound, angiogram, computerized tomography, magnetic resonance imaging and magnetic resonance angiogram. Tests that examine the heart include the echocardiogram and electrocardiogram.
The goal of transient ischemic attack therapy is stroke prevention and involves the use of anti-platelet therapy, anticoagulants, surgery and angioplasty, according to Mayo Clinic. Anti-platelet drugs include clopidogrel and Aggrenox, and anticoagulant medications include heparin, Coumadin and dabigatran. Patients with severe narrowing of the carotid arteries may undergo surgery during which fatty deposits are removed from the arteries. Another option is a carotid angioplasty, which involves the placement of a stent into a carotid artery.Learn more about Conditions & Diseases
