Cerebellar Abiotrophy

Cerebellar abiotrophy (CA) is a rare neurological disease characterized by intrinsic spontaneous degeneration of premature neuronal cells. CA most commonly affects Arabians and Arabian crossbreds but has also been reported in the Oldenburg horse breed and Gotland and Eriskay ponies. Most foals with CA appear normal at birth.
