Understanding the condition

What Is Hydrocephalus?

Hydrocephalus is a condition caused by an abnormal build-up of cerebrospinal fluid within the brain. This fluid normally circulates around the brain and spinal cord before being reabsorbed into the bloodstream.

When cerebrospinal fluid cannot drain or be absorbed properly, it can accumulate within the ventricles of the brain. This may increase pressure on surrounding brain tissue and interfere with neurological function. Hydrocephalus can affect infants, children, and adults, and may develop gradually or suddenly.

When to Seek Urgent Care

Know the Warning Signs

Seek urgent medical attention if you experience:

  • Severe or worsening headaches
  • Repeated vomiting
  • Increasing drowsiness
  • Confusion or altered consciousness
  • Sudden deterioration in walking ability

These symptoms may indicate increasing pressure within the brain and require urgent assessment.

For emergencies, call 000 or attend your nearest Emergency Department.

Assessment & Imaging

How is it diagnosed?

Hydrocephalus is usually diagnosed using brain imaging, which demonstrates enlargement of the ventricles. Clinical assessment helps determine whether symptoms are related to the hydrocephalus and whether treatment is likely to be beneficial.

Neurological Assessment

Assessment of movement, strength, sensation and reflexes.

MRI or CT Scan

MRI or CT may help confirm the diagnosis or investigate significant symptoms.

Functional & Cognitive Assessment

Evaluates how thinking, memory, and executive skills affect a person's abilities.

Treatment

Treatment Options

Treatment is based on your symptoms, examination findings, imaging, and how the condition affects your day-to-day life.

Some patients may require observation and ongoing monitoring before treatment is recommended.

Management may include:

  • Repeat imaging
  • Specialist neurosurgical review

The aim of treatment is to restore normal cerebrospinal fluid circulation and reduce pressure on the brain.
