Hydrocephalus Prevention: Reducing Risk Factors

Hydrocephalus (excess CSF in ventricles) cannot be fully prevented—many causes are congenital or idiopathic. But risk reduction is possible.

Modifiable Risk Factors

1. Prenatal care: Folate (prevents neural tube defects → hydrocephalus), infection screening/treatment (TORCH), avoid teratogens (alcohol, valproate).
2. Vaccination: MMR, varicella, pneumococcal, Hib — prevent meningitis/encephalitis → post-infectious hydrocephalus.
3. Head injury prevention: Helmets (bike, sports), seatbelts, fall-proofing elderly. Traumatic hemorrhage → communicating hydrocephalus.
4. Manage chronic conditions: Spina bifida (in utero repair reduces shunt need), brain tumors (early detection), premature birth (antenatal steroids, magnesium sulfate for neuroprotection).

Non-Modifiable

• Congenital aqueductal stenosis, Dandy-Walker, genetic mutations (L1CAM).
• Intraventricular hemorrhage (preemies) — reduced by NICU care advances.

Early Detection

• Prenatal ultrasound (ventriculomegaly >10 mm).
• Infant head circumference tracking (crossing percentiles).
• Symptoms: bulging fontanelle, rapid head growth, vomiting, sunset eyes, irritability.

Treatment (Not Prevention)

VP shunt, ETV (endoscopic third ventriculostomy), CPC (choroid plexus cauterization). Lifelong monitoring.

While not all cases are preventable, optimizing maternal/child health reduces incidence.
