Hydrocephalus is a condition in which excess cerebrospinal fluid (CSF) builds up inside the brain. This can increase pressure on the brain and may cause headaches, vomiting, difficulty walking, memory problems, vision changes, or other neurological symptoms. Hydrocephalus can affect babies, children, adults, and older people.

Treatment depends on the cause, severity, age, and overall health of the patient. In many cases, hydrocephalus surgery is required to help drain the excess fluid and reduce pressure on the brain.

This blog explains the symptoms, causes, diagnosis, treatment options, surgery, and recovery from hydrocephalus.

What Is Hydrocephalus?

Hydrocephalus occurs when CSF accumulates in the spaces (ventricles) inside the brain. Normally, CSF flows around the brain and spinal cord and is then absorbed into the bloodstream.

When this flow or absorption is disrupted, fluid can build up. This may cause the ventricles to enlarge and increase pressure inside the skull.

Hydrocephalus can develop suddenly or gradually and requires medical evaluation because untreated severe hydrocephalus can cause serious complications.

What Causes Hydrocephalus?

Hydrocephalus can have several causes, including:

Blockage of normal CSF flow
Brain tumors or other growths
Brain infections such as meningitis
Bleeding in or around the brain
Head injury
Congenital abnormalities present from birth
Certain developmental conditions
Problems with CSF absorption
Age-related changes in some older adults

Sometimes, the exact cause may not be immediately clear.

Symptoms of Hydrocephalus

Symptoms can vary depending on the patient’s age and how quickly fluid builds up.

Symptoms in Adults and Older Adults

Common symptoms may include:

Persistent or worsening headache
Nausea or vomiting
Difficulty walking or balance problems
Memory problems
Confusion
Difficulty concentrating
Vision problems
Excessive sleepiness
Urinary urgency or loss of bladder control
Changes in personality or behaviour

In some older adults with normal pressure hydrocephalus (NPH), a combination of walking difficulty, memory changes, and urinary problems can occur.

Symptoms in Babies and Young Children

Signs may include:

Rapid increase in head size
Bulging soft spot on the baby’s head
Poor feeding
Vomiting
Irritability
Excessive sleepiness
Developmental delays
Seizures in some cases
Eyes appearing directed downward

Parents should seek medical attention if they notice unusual or progressive symptoms.

When Is Hydrocephalus an Emergency?

Sudden or severe symptoms may indicate increased pressure inside the brain and require urgent medical assessment.

Seek emergency medical care if a person develops:

Severe or rapidly worsening headache
Repeated vomiting
Loss of consciousness
Seizures
Severe confusion
Sudden vision changes
Difficulty speaking or moving
Significant changes in alertness

Hydrocephalus should not be self-diagnosed because similar symptoms can occur with other neurological conditions.

How Is Hydrocephalus Diagnosed?

A doctor may use a combination of neurological examination, medical history, and imaging tests.

CT Scan

A CT scan can show enlarged brain ventricles and may help identify bleeding, tumors, or other causes of fluid buildup.

MRI Scan

MRI provides detailed images of the brain and can help doctors understand the CSF pathways and identify possible blockages or other abnormalities.

Neurological Examination

Doctors may assess:

Walking and balance
Memory
Eye movements
Muscle strength
Reflexes
Coordination

Additional tests may be recommended depending on the suspected type of hydrocephalus.

Does Hydrocephalus Always Require Surgery?

Not every patient is treated in exactly the same way. Treatment depends on the type and cause of hydrocephalus.

Some patients may require close monitoring and treatment of the underlying condition. However, when excess CSF is causing significant pressure or symptoms, a procedure to improve fluid drainage may be necessary.

The neurosurgeon decides the most appropriate treatment after evaluating the patient’s symptoms and brain imaging.

Hydrocephalus Surgery

The main goal of hydrocephalus surgery is to allow excess CSF to drain properly and reduce pressure on the brain.

Two commonly used surgical approaches are shunt surgery and endoscopic third ventriculostomy (ETV).

1. Ventriculoperitoneal (VP) Shunt Surgery

A VP shunt is one of the most commonly used treatments for hydrocephalus.

During the procedure, a small tube is placed into one of the brain’s ventricles. The tube is connected to a valve and another catheter, which carries excess CSF to the abdomen.

The fluid can then be absorbed naturally by the body.

How Does a VP Shunt Work?

The system generally consists of:

A catheter placed inside the brain
A valve that regulates CSF flow
A second tube that carries fluid to the abdominal cavity

The valve helps control the amount of fluid drained.

2. Endoscopic Third Ventriculostomy (ETV)

ETV is another surgical option for selected patients.

In this minimally invasive procedure, the neurosurgeon uses an endoscope to create a small opening in the floor of the third ventricle. This allows CSF to bypass a blockage and flow through another pathway.

ETV may be appropriate for certain types of obstructive hydrocephalus, but it is not suitable for every patient.

The choice between ETV and shunt surgery depends on factors such as the cause of hydrocephalus, age, imaging findings, and previous treatments.

What Happens During Hydrocephalus Surgery?

The exact procedure varies according to the treatment selected.

Generally, the process may include:

Pre-operative examination and brain imaging
Administration of anesthesia
Placement of the shunt or performance of the endoscopic procedure
Testing the system or confirming appropriate CSF flow
Closing the surgical openings
Monitoring the patient after surgery

The medical team will explain the specific procedure and possible risks before surgery.

Risks of Hydrocephalus Surgery

Like any surgical procedure, hydrocephalus surgery has potential risks.

These may include:

Infection
Bleeding
Shunt blockage
Shunt malfunction
Over-drainage or under-drainage of CSF
Seizures
Need for additional surgery
Anesthesia-related complications

A shunt may require monitoring throughout a patient’s life, and some patients may eventually need revision surgery if the system stops functioning properly.

Recovery After Hydrocephalus Surgery

Recovery depends on the patient’s age, type of hydrocephalus, cause, surgical procedure, and overall health.

After surgery, doctors may monitor:

Consciousness and neurological function
Headache and vomiting
Vision
Walking and balance
Signs of infection
Shunt function, when applicable

Some patients may return home after a short hospital stay, while others may need longer observation or rehabilitation.

Recovery at Home

Patients and caregivers should follow the neurosurgeon’s instructions regarding:

Wound care
Medicines
Physical activity
Follow-up appointments
Warning signs
Returning to work, school, or normal activities

Follow-up imaging may be recommended to monitor the condition.

Warning Signs After Shunt Surgery

Patients with a shunt should contact their medical team urgently if they develop symptoms such as:

Severe or persistent headache
Repeated vomiting
Fever
Redness or swelling around the surgical site
Increasing sleepiness
Confusion
New seizures
Changes in vision
Difficulty walking or new neurological symptoms

These symptoms do not always mean the shunt has failed, but they require medical evaluation.

Can Hydrocephalus Be Prevented?

Not all cases of hydrocephalus can be prevented because some are related to congenital conditions or unavoidable medical problems.

However, certain measures can reduce the risk of conditions that may contribute to hydrocephalus:

Prevent head injuries by using helmets and seat belts.
Seek prompt treatment for serious infections.
Manage conditions that increase the risk of brain bleeding.
Attend regular follow-up appointments when advised.
Seek medical attention for persistent neurological symptoms.

Conclusion

Hydrocephalus occurs when cerebrospinal fluid builds up and can increase pressure on the brain. Symptoms may include headaches, vomiting, walking difficulties, memory problems, vision changes, and changes in bladder control.

Diagnosis commonly involves neurological assessment and brain imaging such as CT or MRI. Depending on the cause and severity, treatment may include monitoring, treatment of the underlying cause, VP shunt surgery, or endoscopic third ventriculostomy (ETV).

Early medical evaluation is important because timely treatment can help manage symptoms and reduce the risk of serious complications. If you or a family member has symptoms suggestive of hydrocephalus, consult a qualified doctor or neurosurgeon for proper evaluation and treatment planning.
