A transient ischemic attack is a serious condition of the brain that is often called a "small stoke" or TIA. A transient ischemic attack is a serious warning sign that a person is at a high risk for eventually having a stroke. About one third or more of all people who experience a transient ischemic attack have a stroke within five years of their first transient ischemic attack.
A transient ischemic attack is the result of a temporary blockage of an artery in the brain by a blood clot or plaque (fatty deposit) that breaks away from the wall of an artery somewhere else in the body and lodges in an artery of the brain. This blocks the flow of oxygen-rich blood to a portion of the brain resulting in symptoms that are similar to symptoms of a stroke. Symptoms include weakness, dizziness or headache. Symptoms of a transient ischemic attack generally go away by themselves in less than an hour as the blockage dissolves. In contrast, symptoms of a stroke do not go away rapidly without treatment and lead to death (necrosis) of the affected brain tissue. For more information on symptoms and complications, refer to symptoms of transient ischemic attack.
Risk factors for transient ischemic attack include having atherosclerosis, hypertension, heart disease, diabetes, high cholesterol and obesity. Other risk factors include being of African-American ancestry, male, drinking excessive amounts of alcohol, smoking and having a family history of heart disease or stroke.
Making a diagnosis of transient ischemic attack includes completing a complete medical evaluation and history and physical examination, including a neurological examination. A neurological exam evaluates the nerves and nervous system and such functions as reflexes, sensation, movement, balance, coordination, vision, and hearing.
Diagnostic testing includes imaging tests that create images of the brain or arteries, such as a CT, MRI and cerebral angiogram of the brain. A cerebral angiogram reveals obstructed or narrowed arteries in the brain and can show blood flow. Another test that is performed is a carotid ultrasonography. This test creates a picture of the carotid arteries in the neck using sound wave technology, which can show narrowing or obstruction of the carotid arteries. The carotid arteries are the main arteries that supply blood to the brain.
A battery of other tests are also performed to test for other conditions that commonly occur with or underlie transient ischemic attack, such as heart disease, atherosclerosis, diabetes, hypertension, and high cholesterol.
It is possible that a diagnosis of transient ischemic attack can be missed or delayed because the symptoms may be mild and can go away in a few minutes. Symptoms can also be similar to symptoms of other diseases and conditions. For more information on misdiagnosis, as well as diseases and conditions that can mimic transient ischemic attack, refer to misdiagnosis of transient ischemic attack.
If caught early, the underlying causes of a transient ischemic attack can often be treated to effectively lower the risk of stroke. For more information on treatment, refer to treatment of transient ischemic attack....more »
A diagnosis of transient ischemic attack may be overlooked or delayed because symptoms may be mild or vague and can go away on their own within minutes. Some people may not seek medical care because they believe that they have only had a mild "spell" and that it is simply a part of normal aging. However, immediate diagnosis and treatment of symptoms of ...more misdiagnosis »
