5 Things to Know About Normal Pressure Hydrocephalus

According to the Alzheimer’s Association, normal pressure hydrocephalus (NPH) is “a brain disorder in which excess cerebrospinal fluid accumulates in the brain’s ventricle,” causing dementia and other symptoms.

It is a fairly rare condition, affecting approximately 700,000 people in the United States, most of whom are over the age of 60.
