Stroke.
The annual incidence of stroke in the elderly approaches 2 per cent. The major tasks of the physician are to attempt to prevent recurrence and to supervise rehabilitation. Prevention of recurrence involves a careful consideration of differential diagnosis, treatment of contributory disease, and the initiation of therapy specific to large vessel infarction (atherothrombotic or cardiogenic embolic), lacunar infarction, or intracerebral hemorrhage. The high prevalence of lacunar infarction and the focal nature of posterior circulation transient ischemic attacks and strokes are not generally appreciated. Cardiogenic embolism due to atrial fibrillation and intracerebral hemorrhage due to congophilic angiopathy are of particular importance in the elderly. Treatment of stroke or transient ischemic attacks should be initiated quickly as the risk of recurrence is highest immediately following the signal event. History, neurologic and neurobehavioral examinations are important adjuncts in compensating for the inadequacy of CT and MRI in enabling the stroke classification necessary for proper treatment. Supportive care and rehabilitation can have a major impact on stroke morbidity and mortality and the management of risk factors can significantly reduce stroke incidence.
