The pathogenesis of normal-pressure hydrocephalus remains obscure, and no preventive measures are known. Risk factors for normal-pressure hydrocephalus have been identified, but we lack population-based epidemiological studies. The most common cause of secondary normal-pressure hydrocephalus is subarachnoid hemorrhage. Approximately 10% of patients with history of subarachnoid hemorrhage will develop normal-pressure hydrocephalus (Black 1990). An increased incidence of hypertension in idiopathic normal-pressure hydrocephalus has been reported (Graff-Radford and Godersky 1987).
