[Prevention of ischemic stroke in old age].

Stroke is one of the main causes of permanent disability and death and the risk increases with age. Primary and secondary prevention therefore have a high priority. The treatment of risk factors, such as high blood pressure, diabetes mellitus and hyperlipidemia is just as important as anticoagulation in atrial fibrillation, in addition to optimization of lifestyle and diet. Platelet function inhibitors play a role in the prophylaxis of recurrence, carotid surgery and stenting are used in selected patients. There is little study evidence for old people, individualized treatment planning takes functional status and comorbidities into account.
