Abstract
Hypertensive encephalopathy is a dramatic syndrome characterized by severe elevation of blood pressure, headache, visual disturbances, altered mental status, and convulsions. Although the syndrome is uncommon, to recognize and treat it promptly is important or the condition may prove to be fatal. Hypertensive encephalopathy should be distinguished from other cerebral complications of severe hypertension by obtaining careful history and performing thorough physical examination. The only definitive criterion for the diagnosis of this syndrome is its prompt response to therapy. If the patient's condition does not improve with hypotensive therapy, the physician should immediately search for alternate diagnoses. Potent drugs are available for prompt reduction of blood pressure. There are few medical emergencies in which the objective response to therapy is so strikingly apparent as in hypertensive encephalopathy. (Arch Intern Med 138:1851-1853, 1978)
