Abstract

Normal Pressure Hydrocephalus (NPH) is a neurological disorder characterized by the abnormal accumulation of cerebrospinal fluid (CSF) in the brain’s ventricles, leading to a triad of symptoms including gait disturbance, urinary incontinence, and cognitive decline. Despite its clinical importance, NPH remains underdiagnosed and often misdiagnosed due to its overlapping features with other neurodegenerative conditions such as Alzheimer’s disease and Parkinson’s disease. This comprehensive review aims to provide a thorough understanding of NPH, including its epidemiology, pathophysiology, clinical manifestations, diagnostic criteria, treatment options, and potential reversibility.
