Cerebrovascular disorder etiology was considered when there was a temporal relationship between an ischemic or hemorrhagic incident other than subarachnoid hemorrhage and development of NPH symptoms. * Meningioma (n = 1) and Recklinghausen's disease (n = 1). These are the same patients as reported in a previous paper [18]. | ||
