Normal Pressure Hydrocephalus


Normal pressure hydrocephalus (NPH) is a neurological condition characterized by the abnormal accumulation of cerebrospinal fluid (CSF) in the brain's ventricles, leading to increased pressure within the skull. It is called 'normal pressure' because, despite the increased intracranial pressure, the CSF pressure measured via spinal tap often falls within the normal range. NPH can cause a range of symptoms, including cognitive impairment, gait disturbances, and urinary incontinence.
