Surgery for normal pressure hydrocephalus does not cure it, but the right patient can see a dramatic reversal of symptoms. A shunt drains excess cerebrospinal fluid off the brain, relieving the pressure behind the gait disturbance, cognitive decline and bladder dysfunction. Gait is usually the first to improve, sometimes within days. Memory and continence often follow, provided surgery comes before the condition has progressed too far.
According to Dr. Gurneet Singh Sawhney, a leading Neurosurgeon in Mumbai, I’m careful with the word cure, because the shunt manages the fluid, it doesn’t undo whatever started it. But when the right patient walks in stooped and shuffling and walks out steady a few weeks later, the difference is hard to call anything else.
Wondering if a shunt could help your relative?
What Does NPH Surgery Actually Do?
The operation drains the trapped fluid, it doesn’t repair the brain, and that distinction shapes the whole result.
Shunt: a soft tube runs from the ventricles down to the belly, quietly siphoning the excess fluid away day and night
Valve: a one-way valve controls the flow, and many are adjustable from outside so the drainage can be fine-tuned later
Relief: with the pressure off the brain, the squashed tissue starts working better and the symptoms loosen their grip
Not a repair: it manages the plumbing rather than reversing the cause, which is exactly why we say controlled, not cured
And the procedure itself is well-trodden, one of the more routine operations in the field. As brain surgery goes, the shunt is about as established as they come.
How Well Does the Surgery Work?
Results lean heavily on picking the right patient, and a tap test does most of that sorting beforehand.
Gait: the walk responds best and most reliably, often the first thing back and the most convincing sign it worked
Test first: drain a little fluid by lumbar puncture, watch for improvement, and that predicts who’ll gain from hydrocephalus treatment.
Mixed: memory and bladder improve less predictably, and a long-standing case recovers less than a fresh one
Honest odds: it isn’t guaranteed, some don’t respond, and the shunt carries its own small risks like blockage or over-drainage
So the win isn’t automatic, it’s earned through careful selection. And since the symptoms mimic Alzheimer’s, this piece on how NPH is mistaken for dementia is worth reading next to this one.
Why Choose Dr. Gurneet Singh Sawhney?
Dr. Gurneet Singh Sawhney trained in neurosurgery in Japan and has more than 18 years placing shunts and judging who’ll actually gain from one. With NPH, picking the right candidate is most of the result, and that’s where the experience earns its keep.
The best days in this work are the simple ones, an elderly patient walking out steadier than they came in. Not everyone gets that. The honest conversation happens before surgery, not after. But when it lands, few operations give back so much for so little.
Frequently Asked Questions
Does a shunt cure normal pressure hydrocephalus?
Not exactly, it controls the fluid and reverses many symptoms rather than curing it.
Which symptom improves most after surgery?
Walking usually improves first and most reliably after a shunt is placed.
How is the right patient chosen for surgery?
A lumbar tap test shows who’s likely to improve before any shunt.
Does early treatment work better?
Yes, the earlier NPH is shunted the more function tends to return.
