Hydrocephalus: Causes, Symptoms, Diagnosis, and Treatment

Hydrocephalus is a serious neurological disorder that occurs when excess cerebrospinal fluid (CSF) accumulates within the ventricles or cavities of the brain. This buildup of fluid increases pressure inside the skull, potentially causing damage to brain tissues and affecting normal brain function.
The term “hydrocephalus” literally means “water on the brain,” but the “water” in this context refers to cerebrospinal fluid—a clear liquid that surrounds and cushions the brain and spinal cord.

Hydrocephalus can affect individuals of all ages, from newborns to older adults. However, it is most common in infants and the elderly. Early detection and treatment are crucial to prevent long-term neurological complications.

Understanding Hydrocephalus

Cerebrospinal fluid (CSF) serves several essential functions:

• It cushions the brain from injury.

• It removes waste products.

• It maintains proper pressure within the brain and spinal canal.

Normally, CSF flows continuously through the ventricles and around the brain and spinal cord before being absorbed into the bloodstream. In hydrocephalus, this balance is disrupted — either due to overproduction, blockage, or poor absorption of CSF — leading to fluid buildup and increased intracranial pressure.

Types of Hydrocephalus

Hydrocephalus is classified into different types depending on its cause and mechanism:

1. Communicating Hydrocephalus

In this type, CSF can still flow between the ventricles, but its absorption into the bloodstream is impaired. This can result from infections, bleeding, or inflammation of brain tissues.

2. Non-Communicating (Obstructive) Hydrocephalus

Here, a blockage within the ventricular system prevents CSF from flowing freely. Common causes include congenital malformations, tumors, or cysts.

3. Congenital Hydrocephalus

Present at birth, congenital hydrocephalus may be caused by genetic factors or developmental disorders such as spina bifida or aqueductal stenosis.

4. Acquired Hydrocephalus

This form develops after birth due to injury, infection (like meningitis), brain hemorrhage, or tumors.

5. Normal Pressure Hydrocephalus (NPH)

This type typically affects older adults. Despite normal CSF pressure levels, fluid accumulates, leading to symptoms such as walking difficulties, memory problems, and urinary incontinence.

Causes of Hydrocephalus

Hydrocephalus can occur due to various underlying conditions, including:

• Congenital defects: Developmental abnormalities of the brain or spinal cord.

• Infections: Meningitis, encephalitis, or other brain infections.

• Brain tumors or cysts: Obstruction of CSF pathways.

• Head injury: Trauma that disrupts normal fluid circulation.

• Subarachnoid hemorrhage: Bleeding in the space around the brain.

• Complications of premature birth: Intraventricular hemorrhage can interfere with CSF flow.

Symptoms of Hydrocephalus

The symptoms vary depending on age, type, and severity of the condition. The Sparsh Diagnostic Centre infographic highlights key signs to watch for.

In Infants:

• A rapid increase in head size

• A bulge on the soft spot (fontanel)

• Vomiting and poor feeding

• Downward deviation of eyes (“sunsetting” eyes)

• Irritability and sleepiness

• Seizures

In Older Children and Adults:

• Headaches (often worse in the morning)

• Nausea and vomiting

• Blurred or double vision

• Balance and coordination problems

• Memory and concentration issues

• Loss of bladder control or frequent urination

• Difficulty walking (especially in normal pressure hydrocephalus)

Complications of Hydrocephalus

If left untreated, hydrocephalus can lead to serious complications, including:

• Developmental delays or intellectual disability in children

• Vision problems

• Seizures

• Loss of mobility or motor coordination

• Permanent brain damage

• Coma or death (in severe, untreated cases)

Early medical evaluation is critical to prevent irreversible neurological damage.

Diagnosis of Hydrocephalus

At Sparsh Diagnostic Centre, modern neuroimaging and diagnostic technologies help in the early and accurate detection of hydrocephalus.

1. Physical and Neurological Examination

The doctor will assess symptoms, head size (in infants), reflexes, and eye movements.

2. Imaging Tests

• Ultrasound: Safe and effective for diagnosing hydrocephalus in infants before the fontanels close.

• CT Scan (Computed Tomography): Detects enlarged ventricles and helps identify the cause of obstruction.

• MRI (Magnetic Resonance Imaging): Provides detailed images of brain tissues and fluid pathways.

• Intracranial Pressure Monitoring: Measures the pressure inside the skull to confirm diagnosis.

Early imaging plays a crucial role in determining the underlying cause and appropriate treatment plan.

Treatment Options for Hydrocephalus

While hydrocephalus cannot always be cured, it can be effectively managed with medical and surgical interventions.

1. Shunt System

The most common treatment involves surgically inserting a shunt, a flexible tube that drains excess CSF from the brain to another part of the body (often the abdomen), where it can be absorbed naturally.
There are two main types:

• Ventriculoperitoneal (VP) shunt – drains fluid to the abdomen.

• Ventriculoatrial (VA) shunt – drains fluid to the heart.

Regular monitoring is necessary as shunts can malfunction or become infected.

2. Endoscopic Third Ventriculostomy (ETV)

In this minimally invasive procedure, a neurosurgeon creates a small opening in the floor of the third ventricle to allow CSF to bypass the obstruction and flow freely. This technique is especially effective for non-communicating hydrocephalus.

3. Medication

In certain cases, medications may temporarily reduce CSF production, though they are rarely a long-term solution.

Living with Hydrocephalus

With timely treatment, many individuals with hydrocephalus lead healthy lives. Regular follow-ups are crucial to monitor shunt function, neurological health, and developmental progress (especially in children).

Tips for Managing Hydrocephalus

• Schedule routine medical checkups and imaging tests.

• Watch for signs of shunt malfunction such as vomiting, headache, or drowsiness.

• Maintain good hygiene to prevent infections.

• Support physical and occupational therapy for developmental improvement.

• Seek prompt medical help if symptoms recur.

Prevention and Early Detection

While hydrocephalus cannot always be prevented, certain measures can help reduce the risk:

• Prenatal care: Regular ultrasounds can detect brain abnormalities early.

• Protect the head: Always use helmets and seat belts to prevent injuries.

• Prevent infections: Timely treatment of meningitis or encephalitis.

• Monitor premature infants: Early screening for intraventricular hemorrhage.

At Sparsh Diagnostic Centre, advanced diagnostic imaging and expert neurologists ensure comprehensive evaluation and care for patients with hydrocephalus and related neurological conditions.

Prognosis

The outcome for hydrocephalus depends on several factors — the cause, age at diagnosis, and timeliness of treatment.

Children treated early often develop normally with appropriate follow-up care. Adults with normal pressure hydrocephalus can also experience significant improvement in mobility and cognition after surgery.

However, untreated hydrocephalus can cause permanent brain injury and disability, highlighting the importance of early diagnosis and management.

When to See a Doctor

Seek immediate medical attention if you or your child experience:

• Unexplained rapid head growth (in infants)

• Severe or persistent headaches

• Nausea, vomiting, or blurred vision

• Problems with walking or balance

• Sudden changes in bladder control

• Confusion or memory loss

Prompt evaluation can prevent complications and improve long-term outcomes.
