Paranoid psychosis presentation in normal pressure hydrocephalus

Abstract

Normal pressure hydrocephalus (NPH) is caused by aqueductal stenosis, where excessive cerebrospinal fluid (CSF) accumulates in the ventricles of the brain. It is characterized by the triad of gait disturbance, cognitive impairment, and urinary incontinence. Late-onset psychosis should be evaluated thoroughly to rule out any organic cause. We present the case of a male patient presenting with delusions, hallucinations, gait disturbances, and urinary incontinence in his late 60s.
