Normal Pressure Hydrocephalus

Surgery for Normal Pressure Hydrocephalus continued...

A shunt operation is not a cure. It does not treat the underlying cause of NPH. It can, however, relieve the symptoms. The shunt remains in place indefinitely. If properly implanted, the shunt often is not obvious to other people.

Shunt operations do not work for everyone with NPH. Many people who undergo a shunt operation have substantial symptom relief. In some, the symptoms improve and then start to worsen again. Others benefit little, if at all. Even the experts are not able to predict perfectly who will benefit and who will not. Many surgeons perform a spinal tap before surgery to test whether the symptoms get better with removal of fluid. In some cases, the person is hospitalized for a few days while fluid is drained slowly through a small tube called a catheter. This is another way of checking whether removing extra fluid will help symptoms.

The earlier the NPH is diagnosed, the better the chances that the surgery will help. In general, people with milder symptoms have better outcomes with this surgery. Like any surgery, the shunt operation can cause complications. Such complications include infection of the shunt and blood clots around the brain. Your neurologist or neurosurgeon will discuss the pros and cons of this operation and whether it might work for you.

Another operation is sometimes used instead of shunt placement. In endoscopic third ventriculostomy, an endoscope (thin tube with a lighted camera on the end) is used to create a small hole in the floor of the ventricles. The hole provides another way for CSF to drain from the brain.

Follow-Up Care for NPH

If you have NPH, you should have regular visits with your neurologist or neurosurgeon. These visits allow the doctor to monitor your symptoms. Changes in symptoms may require adjustments in care.

Prevention of NPH

There is no known way to prevent NPH. A healthy lifestyle, including not smoking, maintaining a healthy weight, and regular exercise, may help avoid conditions such as high blood pressure, heart disease, diabetes, and stroke that might contribute to NPH. Wearing a seatbelt and safety helmet when indicated can help avoid head injury, another cause of NPH.

Outlook for NPH

NPH is a progressive condition, meaning that the symptoms gradually worsen if not treated. In general, the outlook depends on the cause of the hydrocephalus and whether you are a candidate for surgery. Some people improve dramatically after surgery, while others do not. Some are not candidates for surgery. Those who are not candidates for surgery have few treatment options available.

Support Groups and Counseling for NPH

Coping with the symptoms of NPH can be difficult for both you and your family members. The condition affects every aspect of your life, including family relationships, work, financial status, social life, and physical and mental health. You may feel overwhelmed, depressed, frustrated, angry, or resentful. These feelings do not help the situation and usually make it worse.
