Overview
Proventricular Dilation Disease (PDD) is a critical neurological disorder primarily affecting birds, particularly parrots. It's characterized by gastrointestinal and neurological symptoms and can lead to severe health issues if not addressed promptly.
Causes
PDD is primarily caused by Avian Bornavirus (ABV), which affects the nervous system of birds. The exact mechanism of disease progression is not entirely understood, but it involves inflammation of the nerves supplying the gastrointestinal tract.

Managing PDD at home involves ensuring comfort and reducing stress. Offer a quiet environment and monitor for any changes in symptoms.
Prevention
- Quarantining new birds
- Regular health checks
Prognosis & Recovery
The prognosis for PDD is generally poor, but early intervention can improve quality of life. Recovery depends on the severity and response to treatment.
When to See a Vet
