Brain valve to ease the pressure

Published May 31, 2011

NPH, or Normal Pressure Hydrocephalus gives severe problems for those affected. It gives Dementia-like symptoms and each year 2000 Swedes are affected. It is caused by an over-pressure in the brain fluid due to problems with the drainage. This has commonly been treated with an implanted overpressure valve, but there are often problems with clogging of the valve.

– it is about overpressure in the brain fluid. It gives dementia-like symptoms such as incontinence and balance problems. It affects 1–2 percent of those over 60 years of age, says Niclas Roxhed, researcher at the Microsystem technology Lab at KTH.

With a better functioning valve, the excess brain fluid can be drained to the belly.
