Definition

A form of mostly compensated hydrocephalus characterized clinically by a slowly progressive gait disorder progressive intellectual decline, and URINARY INCONTINENCE; Spinal fluid pressure tends to be in the high normal range; This condition may result from processes which interfere with the absorption of CSF including SUBARACHNOID HEMORRHAGE, chronic MENINGITIS, and other conditions;------------------------ (From Adams et al, Principles of Neurology, 6th ed)-------------

Normal pressure hydrocephalus (NPH) is an abnormal increase of cerebrospinal fluid (CSF) in the brain"s ventricles; It occurs if the normal flow of CSF throughout the brain and spinal cord is blocked in some way; This causes the ventricles to enlarge, putting pressure on the brain; Normal pressure hydrocephalus can occur in people of any age, but it is most common in the elderly population; It may result from a subarachnoid hemorrhage, head trauma, infection, tumor, or complications of surgery; However, many people develop NPH even when none of these factors are present; In these cases the cause of the disorder is unknown; Symptoms of NPH include progressive mental impairment and dementia, problems with walking, and impaired bladder control leading to urinary frequency and/or incontinence; The person also may have a general slowing of movements or may complain that his or her feet feel "stuck"; Because these symptoms are similar to those of other disorders such as Alzheimer"s disease, Parkinson"s disease, and Creutzfeldt-Jakob disease, the disorder is often misdiagnosed; Many cases go unrecognized and are never properly treated; Doctors may use a variety of tests, including brain scans (CT and/or MRI), a spinal tap or lumbar catheter, intracranial pressure monitoring, and neuropsychological tests, to help them diagnose NPH and rule out other conditions; Treatment for NPH involves surgical placement of a shunt in the brain to drain excess CSF into the abdomen where it can be absorbed; This allows the brain ventricles to return to their normal size; Regular follow-up care by a physician is important in order to identify subtle changes that might indicate problems with the shunt; The symptoms of NPH usually get worse over time if the condition is not treated, although some people may experience temporary improvements; While the success of treatment with shunts varies from person to person, some people recover almost completely after treatment and have a good quality of life; Early diagnosis and treatment improves the chance of a good recovery------[NINDS NIH website 2006]---------------
