Clinical methods for diagnostic confirmation of stroke subtypes.
Clinicians faced with a patient having a sudden-onset, focal neurological deficit must answer three fundamental questions: is it a stroke?, is it ischemia or hemorrhage? and what kind of ischemic stroke is it? Clinical information (that is, history and examination) is immediately available to every physician, and its role in answering these questions is extremely important, even though a 100% certainty can only be obtained with instrumental diagnostic tools. In fact, when diagnosis is based on properly designed clinical criteria, the percentage of diagnostic mistakes is quite low. Clinical methods are still the best way of orientating topographic and etiologic diagnosis, as well as prognosis. In addition, time might be saved if randomization in clinical trials could be done using clinical methods before complex investigations are applied.
