Hydrocephalus: Causes, Symptoms, Types, Treatment and Cost in India

Hydrocephalus, sometimes called "water on the brain", is a condition in which cerebrospinal fluid (CSF) builds up inside the brain, raising pressure and potentially damaging brain tissue. It can be present at birth, develop in childhood or appear in older adults. It is one of the most common conditions treated by paediatric neurosurgeons, and its burden is especially high in sub-Saharan Africa, where hydrocephalus after newborn infections and neural tube defects is common. The good news is that hydrocephalus is very treatable. Timely surgery with a shunt or an endoscopic procedure can relieve pressure, protect brain development and allow most children and adults to lead active lives. India's neurosurgery centres perform these procedures routinely at affordable costs.

What is Hydrocephalus?

The brain contains fluid-filled spaces called ventricles. CSF is constantly produced, flows through these ventricles, around the brain and spinal cord, and is absorbed into the bloodstream. Hydrocephalus occurs when this flow is blocked or absorption fails, causing the ventricles to enlarge.

Types of hydrocephalus

• Congenital hydrocephalus - present at birth, often linked to aqueductal stenosis, spina bifida (myelomeningocele) or other brain malformations.
• Acquired hydrocephalus - develops after birth due to infection, bleeding, tumour or injury.
• Obstructive (non-communicating) hydrocephalus - CSF flow is blocked within the ventricles, for example by narrowing of the aqueduct or a tumour.
• Communicating hydrocephalus - CSF flows through the ventricles but is not absorbed properly, often after meningitis or bleeding.
• Normal pressure hydrocephalus (NPH) - affects older adults, typically over 60, causing walking difficulty, memory problems and urinary incontinence. It is often mistaken for dementia or Parkinson's disease.

Causes and Risk Factors

• Neural tube defects such as spina bifida, which are more common where maternal folic acid intake is low.
• Infections - neonatal sepsis and bacterial meningitis are a leading cause of infant hydrocephalus in Africa; tuberculous meningitis is an important cause in South Asia and other regions where TB is common.
• Bleeding in the brain, particularly intraventricular haemorrhage in premature babies, and subarachnoid haemorrhage in adults.
• Brain tumours and cysts blocking CSF pathways, especially in the posterior fossa in children.
• Head injury and previous brain surgery.
• Genetic conditions, such as X-linked aqueductal stenosis, and infections during pregnancy like toxoplasmosis and cytomegalovirus.

Symptoms of Hydrocephalus

In babies

• Rapidly increasing head size.
• Bulging, tense soft spot (fontanelle) on the top of the head.
• Eyes fixed downwards ("sunsetting eyes").
• Vomiting, poor feeding, irritability and sleepiness.
• Prominent scalp veins and seizures.

In older children and adults

• Headache, often worse in the morning.
• Nausea and vomiting.
• Blurred or double vision.
• Drowsiness, poor balance and coordination.
• Decline in school performance, memory or personality changes.

In normal pressure hydrocephalus

• A slow, shuffling, wide-based "magnetic" walk.
• Forgetfulness and slowed thinking.
• Urinary urgency or incontinence.

Warning signs needing emergency care

Severe headache with repeated vomiting, extreme drowsiness, seizures, or difficulty waking up can indicate dangerously raised pressure or a blocked shunt. These need immediate hospital care.

Diagnosis

• Head circumference measurement and examination in infants.
• Cranial ultrasound through the fontanelle in babies, and antenatal ultrasound before birth.
• CT scan - quick and useful in emergencies.
• MRI brain - shows the cause, the site of obstruction and helps decide between shunt and endoscopic surgery.
• Eye examination for swelling of the optic disc (papilloedema).
• Lumbar tap test or external lumbar drainage in suspected NPH - improvement in walking after draining fluid predicts benefit from a shunt.

Treatment Options for Hydrocephalus

Hydrocephalus is treated surgically. Medicines may be used briefly but do not provide a long-term solution.

Ventriculoperitoneal (VP) shunt

The most common treatment. A thin tube is placed in a brain ventricle and tunnelled under the skin to the abdomen, where the fluid is absorbed. A valve controls the flow. Programmable valves, whose pressure setting can be adjusted from outside the body with a magnet, are widely available in India and are often preferred for NPH and complex cases. Shunts can also drain into the heart (VA shunt) or chest cavity when the abdomen is unsuitable.

Endoscopic third ventriculostomy (ETV)

Used mainly for obstructive hydrocephalus. Through a small hole in the skull, the surgeon uses an endoscope to make an opening in the floor of the third ventricle, creating a natural bypass for CSF. ETV avoids an implanted device. In infants, it may be combined with choroid plexus cauterisation (ETV/CPC), a technique developed and widely used in Africa, to reduce shunt dependence.

Other treatments

• Removal of the cause - for example, removing a tumour or cyst may restore normal CSF flow.
• Temporary external drains in emergencies or during infection.
• Shunt revision - shunts can block, break or become infected over time and may need replacing.
• Treatment of associated spina bifida with closure surgery in newborns.

Possible complications of shunt surgery

Shunts are life-saving, but families should understand the possible problems so they can act quickly:

• Blockage (obstruction) - the most common problem, causing symptoms of raised pressure to return.
• Infection - usually in the first few months after surgery, with fever, redness along the tubing, abdominal pain or irritability.
• Over-drainage - too much fluid drains, causing headaches that are worse on standing, or in some cases fluid or blood collections around the brain. Programmable or anti-siphon valves help reduce this risk.
• Under-drainage - not enough fluid drains, so symptoms persist; programmable valves can be adjusted without further surgery.
• Disconnection or migration of the tubing as a child grows.

ETV avoids most device-related problems, but the new opening can close over time in a minority of patients, so follow-up remains important whichever procedure is chosen.

Final cost depends on the patient's age, cause of hydrocephalus, type of valve, need for intensive care and hospital chosen. Contact Satyug Healthcare at +91-8860606766 / +91-9910655125 (WhatsApp) for a free medical opinion and cost estimate.

Recovery and Living with Hydrocephalus

Most patients go home within a week of surgery. Babies often show reduced head growth and a softer fontanelle within days. Adults with NPH may notice better walking within weeks, while memory and bladder symptoms improve more slowly. International patients usually stay in India for 2 to 3 weeks for surgery and follow-up scans.

• Learn the signs of shunt malfunction - headache, vomiting, sleepiness, irritability or swelling along the shunt - and seek help immediately.
• Keep a copy of the operation note and valve details (especially for programmable valves) and bring them to every hospital visit.
• Inform doctors before MRI scans if a programmable valve is in place, as settings may need checking afterwards.
• Attend regular neurosurgery and developmental follow-up; children may benefit from therapy and educational support.
• Most children and adults can go to school, work and play normally; contact sports should be discussed with the surgeon.

Prevention

Some forms can be prevented: folic acid before and during early pregnancy reduces neural tube defects; good antenatal and newborn care, prompt treatment of neonatal infections, vaccination against meningitis-causing bacteria, and wearing helmets reduce acquired hydrocephalus.

Frequently Asked Questions

Can hydrocephalus be cured?

Hydrocephalus is usually controlled rather than cured. A shunt or ETV can manage it long term. In some cases, such as when a tumour is removed, the problem may resolve completely.

Which is better, VP shunt or ETV?

It depends on the cause and age. ETV is often preferred for obstructive hydrocephalus in older children and adults because it avoids an implant. Shunts work for most types, including communicating hydrocephalus and NPH. The neurosurgeon decides based on MRI findings.

How long does a shunt last?

Some shunts work for many years, but a significant number of patients, especially children, need at least one revision during their lifetime due to blockage, infection or growth.

Will my child develop normally after treatment?

Many children develop well, especially when treated early. Outcomes depend on the cause and any associated brain conditions. Regular developmental follow-up is important.

Is normal pressure hydrocephalus reversible?

Yes, in many patients. Walking often improves noticeably after shunting, which is why NPH should be considered in older adults with gait, memory and bladder problems.

Can a person with a shunt travel by air?

Yes. Air travel is generally safe with a shunt. Carry your medical records and valve details while travelling.

How long do I need to stay in India?

Usually about 2 to 3 weeks, including tests, surgery and a post-operative check before flying home.
