Idiopathic normal pressure hydrocephalus. Retrospective review of pathogenesis and modern theories
Abstract
Idiopathic normal pressure hydrocephalus is a chronic, progressive degenerative brain disease characterized by ventricular enlargement disproportionate to other cerebrospinal fluid (CSF) spaces with normal CSF pressure. This disease presents with gait disturbance, cognitive impairment, and incontinence. The pathophysiology and morphogenesis of this condition are not well studied. Since the first description by S. Hakim in 1964, a number of experimental and morphological studies have focused on investigation of the disease mechanisms. This review retrospectively analyzed and summarized principal ideas about the pathogenesis of idiopathic normal pressure hydrocephalus.
