Normal Pressure Hydrocephalus (NPH) is a condition that can cause walking problems and memory loss in adults. Unlike some other causes of memory loss, NPH is often treatable. Because of this, it is important to know the signs and seek help early. Many people with NPH notice changes in how they walk, think, or control their bladder. With the right treatment, many can improve their daily lives.
What is Normal Pressure Hydrocephalus?
Normal Pressure Hydrocephalus is a brain condition. It happens when extra fluid builds up in the brain’s spaces, called ventricles. Even though there is more fluid, the pressure inside the brain often stays normal. As a result, the brain can get squeezed, leading to symptoms. NPH mostly affects older adults. However, it can sometimes occur in younger people after a head injury or brain infection. Because NPH is treatable, early diagnosis is key.
Common Symptoms of NPH
People with NPH often have a group of symptoms. These symptoms can look like other problems, such as Alzheimer’s disease or Parkinson’s disease. Yet, NPH is different because it is one of the few treatable causes of walking and memory problems. The main symptoms include:
Because these symptoms can be mild at first, they are sometimes missed. However, noticing them early can help with diagnosis and treatment.
Causes and Risk Factors
Normal Pressure Hydrocephalus can happen for different reasons. Sometimes, doctors do not find a clear cause. This is called idiopathic NPH. Other times, NPH develops after an event that affects the brain. For example, it can follow:
Older age is the main risk factor. However, anyone with a history of brain injury or infection may also be at risk. Because NPH can look like other conditions, it is important to consider it when walking or memory problems appear.
How NPH is Diagnosed
Doctors use several steps to diagnose NPH. First, they ask about symptoms and do a physical exam. Next, they may order brain scans, such as MRI or CT scans. These scans show if there is extra fluid in the brain. Sometimes, doctors do special tests, like removing a small amount of spinal fluid. This is called a lumbar puncture or spinal tap. If symptoms improve after this test, it may suggest NPH. Because NPH diagnosis can be tricky, doctors often use a team approach. They may include neurologists, neurosurgeons, and other specialists.
Treatment Options for NPH
Normal Pressure Hydrocephalus is one of the few treatable causes of walking and memory problems. The main hydrocephalus treatment option is surgery. Doctors place a thin tube, called a shunt, into the brain. This shunt drains extra fluid to another part of the body, often the belly. As a result, pressure on the brain is reduced. Many people see improvement in walking, thinking, and bladder control after surgery. However, not everyone responds the same way. Doctors will discuss the risks and benefits before surgery. In some cases, physical therapy and memory exercises may help as well.
Living with NPH: Lifestyle Tips and Support
Even after treatment, some people need extra support. For example, using a cane or walker can help with balance. Memory aids, such as notes or reminders, can make daily life easier. Staying active and doing brain exercises may also help. Family and friends play a big role in support. Because NPH can affect mood, talking to a counselor or joining a support group can be helpful. Regular check-ups with your doctor are important to watch for changes or problems with the shunt.
Preventing Complications of NPH
After treatment, it is important to prevent problems. For example, watch for signs of shunt blockage, such as headaches or confusion. If you notice new symptoms, contact your doctor right away. Keeping up with follow-up visits helps catch issues early. Staying safe at home can also prevent falls. Remove loose rugs, use night lights, and keep walkways clear. Because infections can affect the shunt, practice good hygiene and report any fevers or redness near the shunt site. With the right care, many people with NPH can lead active lives.
