Hydrocephalus: Symptoms, Diagnosis & Treatment
A clear, clinically structured guide to hydrocephalus, covering causes, diagnosis, and shunt surgery for fluid buildup in the brain.
Treatment usually begins with
Specialist Assessment
Diagnostic Imaging
Medical Management
Care Team Follow-up
Your neurology team will confirm the right diagnostic and treatment pathway based on your symptoms and imaging findings.
You may need this evaluated if...
A hydrocephalus evaluation is recommended if you or your child has:
- Persistent headache with vomiting
- Increasing head size in an infant
- New difficulty with balance, memory or vision
- Drowsiness or reduced alertness
Not every headache means hydrocephalus, but these combined symptoms deserve prompt evaluation.
What is Hydrocephalus?
Hydrocephalus is a buildup of cerebrospinal fluid within the brain's cavities, which increases pressure inside the skull and can affect brain function if untreated.
Fluid Buildup
Excess cerebrospinal fluid raises pressure inside the skull.
Any Age
Hydrocephalus can occur in infants, children or adults.
Imaging Confirms It
A CT or MRI scan shows the enlarged fluid spaces in the brain.
Manageable With Surgery
A shunt or endoscopic procedure usually drains the excess fluid effectively.
Common Symptoms
- Persistent headache, often worse in the morning
- Nausea or vomiting
- Blurred or double vision
- Difficulty with balance or walking
- In infants, a rapidly increasing head size
- Memory or concentration difficulty in adults
What Increases Your Risk
A combination of medical, lifestyle and hereditary factors can increase the likelihood of this condition.
How It Is Diagnosed
A structured assessment confirms the diagnosis and helps guide the right treatment plan.
1. Neurological examination
Checking for signs of raised pressure inside the skull.
2. Brain imaging (CT/MRI)
Imaging confirms the extent of fluid buildup and its likely cause.
3. Pressure monitoring, where needed
In select cases, direct pressure measurement guides treatment planning.
Treatment Approaches
Medical Care
- Close Monitoring for Mild Cases
- Medication to Reduce Fluid Production
- Regular Imaging Follow-up
- Management of the Underlying Cause
Surgical Care
Most cases benefit from a shunt to drain excess fluid, or an endoscopic procedure, to relieve pressure and prevent complications.
Treatment decisions are based on symptoms, imaging, timing and overall health, not a single test.
Know When to Act
Recognising these signs early and acting promptly is important for the best outcome.
Book an Assessment
Schedule a consultation for a routine evaluation or ongoing symptoms.
- Imaging shows a mild, stable amount of fluid
- You want a second opinion on an existing scan
- Symptoms are mild and not worsening
Seek Urgent Care
Call for emergency care immediately if you notice any of the following.
- Rapidly worsening headache with vomiting
- A fast-growing head size in an infant
- New confusion, drowsiness or vision loss
