Hydrocephalus: Symptoms, Diagnosis & Advanced Treatment
Hydrocephalus is a neurological condition characterized by an abnormal accumulation of cerebrospinal fluid (CSF) within the brain’s ventricles.
This buildup increases pressure inside the skull and may interfere with normal brain function. Without timely diagnosis and treatment, hydrocephalus can lead to permanent neurological damage, affecting movement, memory, vision, balance, and overall quality of life.
Although hydrocephalus is often associated with infants, it can occur at any age, including children, adults, and older adults. Thanks to significant advances in neurosurgery and neuroimaging, most patients can now receive effective treatment that relieves pressure on the brain and restores normal cerebrospinal fluid circulation.
What Is Hydrocephalus?
Hydrocephalus occurs when cerebrospinal fluid, which normally circulates around the brain and spinal cord, cannot flow or drain properly. As fluid accumulates inside the brain’s ventricles, they enlarge, placing pressure on surrounding brain tissue.
Vital Roles of Cerebrospinal Fluid:
- Protecting the brain from injury
- Delivering nutrients to brain tissue
- Removing waste products
- Maintaining normal pressure within the brain
Classifications
Types of Hydrocephalus
Hydrocephalus can be classified into several types depending on its cause and the patient’s age.
Congenital Hydrocephalus
Present at birth and may result from abnormal brain development, genetic conditions, or infections during pregnancy.
Acquired Hydrocephalus
Develops after birth due to conditions such as brain tumors, head injuries, brain hemorrhage, stroke, or meningitis.
Normal Pressure Hydrocephalus (NPH)
Mainly affects older adults. Characterized by the classic triad: difficulty walking, memory impairment, and urinary incontinence. Often overlooked as it resembles Alzheimer's or Parkinson's.
Communicating vs. Non-Communicating
Communicating: CSF flows but isn't absorbed properly. Non-Communicating (Obstructive): A blockage prevents CSF circulation (often due to tumors or cysts).
What Causes Epilepsy?
Epilepsy has many possible causes, and in some patients, the exact cause cannot be identified. Identifying the underlying cause is one of the most important steps in selecting effective treatment.
Brain tumors
Traumatic brain injury
Intraventricular hemorrhage
Stroke
Meningitis / Infections
Congenital abnormalities
Arachnoid cysts

Symptoms of Hydrocephalus
Symptoms vary according to the patient’s age and the severity of pressure on the brain
- Persistent headaches
- Nausea and vomiting
- Blurred or double vision
- Difficulty walking
- Poor balance
- Memory problems
- Difficulty concentrating
- Personality changes
- Excessive sleepiness
- Urinary incontinence
How is Hydrocephalus Diagnosed?
A thorough evaluation is essential to determine both the cause and the most appropriate treatment.
Neurological Exam
Evaluation of walking ability, balance, muscle strength, reflexes, memory, cognitive function, and vision.
CT Scan
Provides rapid assessment, particularly in emergency situations involving acute hydrocephalus.
Brain MRI
The most accurate study. Determines ventricular enlargement, cause of obstruction, and associated conditions.
Lumbar Tap Test
For suspected NPH. Removing a small amount of CSF helps predict whether surgery will improve symptoms.
Surgical Solutions
Hydrocephalus Treatment
Treatment aims to restore normal cerebrospinal fluid circulation and relieve pressure on the brain.
Ventriculoperitoneal (VP) Shunt Surgery
The most common treatment for hydrocephalus is the placement of a ventriculoperitoneal (VP) shunt. The shunt continuously diverts excess cerebrospinal fluid away from the brain to the abdominal cavity, where it is safely absorbed.
Modern programmable shunt systems allow pressure adjustments externally without requiring additional surgery in many patients.
- Ventricular catheter
- Pressure-regulating valve
- Distal catheter
Endoscopic Third Ventriculostomy (ETV)
For selected patients with obstructive hydrocephalus, ETV provides an effective alternative to shunt placement. During this minimally invasive procedure, a tiny opening is created in the floor of the third ventricle, allowing CSF to bypass the obstruction and flow naturally. Advantages of ETV: .
- No permanent implanted shunt
- Lower long-term shunt-related complications
- Faster recovery in selected patients
Not every patient is a candidate for ETV, making careful evaluation essential.
Treating the Underlying Cause
When hydrocephalus results from another condition, treatment may also involve addressing the root problem to improve long-term outcomes. This may include:
- Brain tumor removal
- Treatment of brain infections
- Management of hemorrhage
- Treatment of cysts

Patient Guide
Frequently Asked Questions
Many patients experience significant improvement after appropriate treatment. The long-term outcome depends on the underlying cause, how early treatment begins, and the patient’s overall neurological condition.
In many patients, the VP shunt remains in place for many years. However, periodic follow-up is essential because shunts may occasionally require adjustment or replacement.
A VP shunt diverts excess cerebrospinal fluid through an implanted drainage system, while Endoscopic Third Ventriculostomy (ETV) creates a new internal pathway for cerebrospinal fluid circulation without implanting a permanent shunt. The most suitable option depends on the patient’s condition.
Yes. Hydrocephalus can occur at any age. In older adults, Normal Pressure Hydrocephalus is an important and potentially treatable cause of walking difficulties, memory problems, and urinary incontinence.
Hydrocephalus surgery is routinely performed by experienced neurosurgeons and has a high success rate. Modern surgical techniques and advanced technologies have significantly improved safety and long-term outcomes.
