Hydrocephalus

Hydrocephalus is a congenital neurological disorder characterized by abnormal accumulation of cerebrospinal fluid (CSF) in the brain, leading to increased intracranial pressure and neurological deficits.

Detailed Description

Chihuahuas are predisposed due to their domed skulls and open fontanelles. The condition can cause domed skull, persistent fontanelle, behavioral changes, seizures, and vision loss. Severity varies from subclinical to severe neurological impairment.

Common Symptoms

  • Domed skull
  • Persistent fontanelle
  • Ataxia
  • Seizures
  • Blindness
  • Circling
  • Behavioral changes

Management Options

  • Diuretics (acetazolamide)
  • Corticosteroids
  • Anti-seizure medications
  • Ventriculoperitoneal shunt (rare in small dogs)

Frequently Asked Questions

Is hydrocephalus always fatal?

Not always; mild cases can be managed, but severe cases have poor prognosis.

Can hydrocephalus be detected early?

Yes, via ultrasound in young puppies with open fontanelle.

Is the condition inherited?

There is a genetic predisposition, but inheritance is not fully understood.

Can affected dogs live normal lives?

Mildly affected dogs may live relatively normal lives with management.

Is surgery an option?

Rarely, due to size and risks, but shunting is possible in select cases.
