Normal Pressure Hydrocephalus Center
Understanding normal pressure hydrocephalus
Normal pressure hydrocephalus (NPH) is a mild, difficult-to-diagnose type of hydrocephalus, commonly referred to as "water on the brain." Symptoms of normal pressure hydrocephalus are caused by an increase of fluid in the brain known as cerebrospinal fluid (CSF). The increase in the cerebrospinal fluid above normal levels is so mild that NPH can be hard to detect and accurately diagnose. Individuals with normal pressure hydrocephalus often have a combination of three symptoms that can help establish the diagnosis: mental confusion, gait disturbance and urinary incontinence.
Because NPH symptoms are similar to those of Alzheimer's, Parkinson's and other movement disorders, NPH is often misdiagnosed or unrecognized which results in patients not receiving the appropriate treatment. Without treatment, symptoms may get worse over time, and early diagnosis and treatment may improve the chance of a good recovery.
Providing expert diagnosis
At the Normal Pressure Hydrocephalus Center at the Northwell Health Institute for Neurology and Neurosurgery, we use comprehensive techniques to make sure we make the right diagnosis (and therefore choose the right treatment) including:
- Detailed patient history and examination
- CT scan (Computerized Tomography) of the head
- MRI (Magnetic Resonance Imaging)
- Neuropsychological testing
- Gait testing
- Spinal tap or lumbar puncture (LP)
- Lumbar CSF drainage
- Intracranial pressure monitoring
We are members of the International Hydrocephalus Imaging Working Group (IHIWG), an organization that advances the study of hydrocephalus, using a wide range of imaging modalities. Our physicians have presented at IHIWG on cerebrospinal fluid physiology and modeling.
Our staff is dedicated to educating the next generation of medical professionals at our renowned medical school.
We’re empowering imagination and supporting pioneering discovery to transform our field and create a better tomorrow.
