The prognosis for an ischemic stroke is generally better than that of a hemorrhagic stroke, reports the University of Maryland Medical Center. However, the prognosis varies widely depending on which part of the brain is affected, how quickly treatment is received and what kind of ischemic attack occurs.
Strokes are the fourth most common cause of death in the United States, according to the University of Maryland Medical Center. However, approximately 75 percent of people who experience a stroke survive the first year, and half of those people survive more than five years. However, long-lasting physical symptoms, such as weakness on one side of the body, and mental symptoms, such as confusion, are common. Ischemic strokes make up approximately 90 percent of all strokes.
The most dangerous type of ischemic stroke is an embolic stroke, according to the University of Maryland Medical Center. This occurs when a blood clot gets dislodged from another part of the body, typically the heart, and gets stuck in an artery. Thrombotic strokes, which occur when a clot develops in the brain, and lacunar strokes, which affect a cluster of small arteries, are usually less severe. The type of stroke with the best prognosis is known as a transient ischemic attack, which typically causes symptoms for only a few days at most and does not usually cause lasting damage. However, since it indicates an increased risk of a more severe stroke later, it requires serious consideration and care.
