Normal Pressure Hydrocephalus: A Treatable Cause of Walking & Memory Problems
Normal pressure hydrocephalus is a build-up of spinal fluid in the brain’s ventricles in older adults. It produces a classic triad: a wide-based, shuffling, “magnetic” walk; slowed thinking and memory; and urinary urgency. Because these symptoms overlap with Parkinson’s disease and Alzheimer’s, NPH is frequently missed — yet it is one of the few forms of dementia that can be reversed.
We confirm the diagnosis with a large-volume spinal tap or lumbar drain trial and objective gait testing before and after. Patients who improve are candidates for a shunt, which drains excess fluid continuously.
Symptoms
- Difficulty walking: short steps, feet feel stuck to the floor, frequent falls
- Memory and thinking slowed
- Urinary urgency or incontinence
- Symptoms progress over months
How it is diagnosed
MRI or CT showing enlarged ventricles; a lumbar puncture or 3-day lumbar drain trial with timed walking tests.
Treatment options
Without surgery
None reverse the condition; physical therapy supports safety.

Common questions
How much improvement can be expected from a shunt?
Walking improves most reliably and often dramatically in patients who responded to the spinal tap test. Bladder symptoms usually improve; memory improves in many but not all. Early treatment gives the best chance of recovery.
