Hydrocephalus: Understanding This Rare but Dangerous Brain Condition

Hydrocephalus, a rare but dangerous brain condition, causes increased intracranial pressure due to fluid accumulation in the brain. If this condition is left untreated and treatment is delayed, it can lead to severe neurological damage or even be fatal. The following is an in-depth introduction to hydrocephalus.

Causes

Hydrocephalus mainly forms for the following reasons:

1. Obstructed cerebrospinal fluid circulation: cerebrospinal fluid circulation in the brain is obstructed, such as by narrowing or blockage of the cerebrospinal fluid pathways, causing fluid to accumulate.
2. Excess cerebrospinal fluid production: when cerebrospinal fluid is produced in excess and cannot be properly processed by the brain, it leads to fluid accumulation.
3. Insufficient cerebrospinal fluid absorption: cerebrospinal fluid cannot be properly absorbed, which may be due to brain disease or impaired absorption function of the meninges.
4. Brain trauma or disease: head trauma, meningitis, brain tumors, and other diseases may also trigger hydrocephalus.

Symptoms

The symptoms of hydrocephalus are diverse and vary as the condition progresses. Common symptoms include:

• Headache: common in the morning and worsening as the condition deteriorates.
• Nausea and vomiting: caused by increased intracranial pressure.
• Blurred vision: vision is affected, and double vision or reduced vision may occur.
• Difficulty walking: unsteady gait or difficulty walking.
• Declining memory: especially in adults, cognitive function may decline.
• Symptoms specific to infants and young children: such as an enlarged head circumference, visible veins under the scalp, and a bulging anterior fontanelle.

Treatment Methods

Treatment approaches for hydrocephalus include:

1. Ventriculoperitoneal shunt (VP Shunt): drains excess cerebrospinal fluid from the ventricles into the abdominal cavity to reduce fluid accumulation in the brain.
2. Endoscopic third ventriculostomy (ETV): uses an endoscope to create an opening in the third ventricle, allowing cerebrospinal fluid to flow again.
3. Medication: uses drugs such as diuretics to reduce the production of cerebrospinal fluid.
4. Supportive care: includes monitoring and managing intracranial pressure and providing comprehensive medical care.

Preventive Measures

Although hydrocephalus cannot be completely prevented, the following measures can reduce the risk:

• Prevent and promptly treat meningitis: actively prevent infection and treat it promptly when it occurs.
• Protect the head: avoid head injuries and use safety equipment such as seat belts and helmets.
• Regular health checkups: especially for those with a family history, regular health checkups should be conducted to detect potential problems early.
• Healthy lifestyle: maintain a balanced diet, moderate exercise, and adequate sleep to strengthen the body’s resistance.
