The treatment approach to stroke is determined by localizing the problem (identifying the vascular territory involved) and subsequently by using the patient’s history, the stroke subtype, and investigational tools to discover the stroke mechanism. The medical treatment of stroke can be divided into acute (within 3-4.5 hours of stroke onset), subacute, and chronic phases.
