Surgery for Normal Pressure Hydrocephalus
Normal pressure hydrocephalus (NPH) is a treatable cause of memory loss, difficulty walking and incontinence in elderly individuals. Treatment usually involves placement of a ventriculoperitoneal or a lumbar-peritoneal shunt to divert excess spinal fluid from the brain. Careful diagnostic work-up is essential for patients suspected of having NPH since other degenerative conditions may mimic NPH, but do not respond to treatment with a CSF shunt. Recent technological advances, including the development of programmable shunt valves, have made surgery for NPH safer and have decreased the need for re-operation.
