Normal pressure hydrocephalus NPH is a brain disorder in which excess cerebrospinal fluid CSF accumulates in the brain's ventricles, causing thinking and reasoning problems, difficulty walking, and loss of bladder control. Normal pressure hydrocephalus is called "normal pressure" because despite the excess fluid, CSF pressure as measured during a spinal tap is often normal. As brain ventricles enlarge with the excess CSF, they can disrupt and damage nearby brain tissue, leading to difficulty walking, problems with thinking and reasoning, and loss of bladder control.
Normal pressure hydrocephalus can sometimes be treated with surgical insertion of a shunt, a long, thin tube that drains excess CSF from the brain to the abdomen. Surgery is most likely to help correct difficulties walking, but thinking changes and loss of bladder control are less likely to improve. Normal pressure hydrocephalus primarily affects people in their 60s and 70s.
In fact, less than 20 percent of people with the disease are properly diagnosed. Learn more: Key Types of Dementia. In some cases, normal pressure hydrocephalus is caused by other brain disorders such as a tumor, head injury, hemorrhage, infection or inflammation. But in most cases, the cause of the fluid buildup remains unknown.
Normal pressure hydrocephalus is one of the few causes of dementia that can be controlled or reversed with treatment.
If symptoms and from an evaluation and MRI point to normal pressure hydrocephalus, a high-volume spinal tap may be used to identify if an individual has the potential to benefit from surgical insertion of a shunt. In this procedure, doctors remove a large amount of spinal fluid and observe the individual for 30 to 60 minutes, looking for any improvements in walking or thinking and reasoning.
Most people originally suspected of having normal pressure hydrocephalus do not improve following a cerebrospinal fluid removal test. Researchers have not found effective nonsurgical treatments for normal pressure hydrocephalus. More research is needed to:.

In a Mayo Clinic study, among 41 older adults with suspected normal pressure hydrocephalus, all had difficulty walking, 30 experienced cognitive decline, and 14 reported loss of bladder control. Only 12 of the 41 had all three symptoms. To confirm a diagnosis of normal pressure hydrocephalus, one or more of the following tests are done:.
Few studies have explored the benefits of shunt insertion. Most of these studies were small and followed participants for a limited time. The SINPHONI-2 trialpublished in the June issue of Lancetfound that people with normal pressure hydrocephalus might benefit from lumboperitoneal shunt surgery but further studies need to be done to confirm the findings. Available data suggests that difficulty walking is the symptom most likely to improve. Several studies found a ificant rate of postsurgical complications and also showed that the short-term benefits of shunt insertion tend to decline over time.
