Abstract
Among patients who show abnormal ventricular dilatation, those with normal pressure hydrocephalus (NPH) should be discriminated because they have a neurosurgically treatable disease (1). However, NPH is not so easily diagnosed because similar symptoms are presented by dementia caused by brain atrophy within the same age distribution. From the analysis of the pathophysiological mechanism of NPH, the authors have reported previously that the so-called sleep stage of NPH patients is frequently interrupted by arousal responses accompanied by pressure waves (8).
