Hydrocephalus before (A) and after (B) CSF diversion
Normal pressure hydrocephalus (NPH) is caused by excessive accumulation of cerebrospinal fluid (CSF) and enlargement of the brain’s ventricular system, putting increased pressure on surrounding brain tissue, and leading to a distinctive gait disturbance, urinary incontinence and dementia.
NPH can be effectively treated by a surgical procedure to divert the CSF from the ventricles into the peritoneal cavity via a ventriculoperitoneal shunt.
Early diagnosis and treatment are important for this surgical treatment to be effective.
However NPH is frequently unrecognized or misdiagnosed as arthritis, Parkinson’s disease, Alzheimer’s disease, or “senility”, leading to other ineffective treatments and nursing home confinement.
However, many patients with dementia or gait problems and large ventricles on a brain imaging study will not improve after shunting. Performing surgery on all such patients, without further selection, can result in ineffective surgery, and more importantly other potential complications like bleeding around the brain (a subdural hematoma).
Therefore selecting the patients with suspected NPH who are most likely to benefit from surgery is of the utmost importance. Studies have shown that careful evaluation of patients using objective measures during prolonged CSF drainage via a lumbar drain is the most sensitive and specific way to predict which patients will improve with surgery.
The neurologists and neurosurgeons at the Monmouth Neuroscience Center have developed a multidisciplinary hydrocephalus assessment program to evaluate patients with suspected NPH and determine who is most likely to benefit from a shunting procedure.
