Acute cerebrovascular disease (CBVD) has an annual incidence of 100–300 per 100,000 inhabitants in the industrialized countries (1,2). CBVD occurs mainly in the elderly. Acute mortality is around 15%. Disablement and decreased quality of life are common consequences. Institutionalized care will be needed after the acute phase for around one-third of the patients (3). Considering the volume of patients and the growing proportion of elderly persons in most countries, stroke poses a major problem for health care. An effective diagnostic work-up as the base for therapy to improve the situation is, therefore, a matter of great public concern, for humanitarian as well as economic reasons.
