Normal pressure hydrocephalus, or NPH, is a brain condition that occurs when fluid builds up inside or around the brain, disrupting certain brain-related functions.

Cerebrospinal fluid, which cushions the brain and spinal cord, is the type of fluid that builds up. Typically, your body makes just enough of this fluid each day and absorbs that same amount, , but sometimes too much fluid can build up, leading to NPH. 

"If that increases abnormally, it can build up in these chambers, called ventricles, in the brain," TheNews chief medical correspondent Dr. Jon LaPook explained. "And that can cause pressure on normal brain tissue."

As a result, he said, people with the condition may experience symptoms including "trouble thinking, trouble walking and trouble with urinary incontinence," though not every patient will have all the same symptoms.

"Usually, it just comes out of the blue. We really don't know why," LaPook said.

An MRI brain scan can detect the issue, and medical experts say it is usually treatable. The treatment typically involves a surgical procedure to implant a shunt in order to drain the fluid. LaPook said he recently had a patient who was treated this way, "and now he's feeling perfectly fine."

The condition is relatively uncommon, but is more likely to occur in older people. 

According to the , NPH affects bout 0.2% of people between the ages 70 and 80, and about 5.9% of those over 80.

"Getting prompt diagnosis and treatment helps improve your chances of a good outcome," Johns Hopkins notes on its website.
