Cerebellar Abiotrophy/Cerebellar Cortical Abiotrophy/Cerebellar Cortical Degeneration/Cerebellar Degeneration
Cerebellar abiotrophy results from a loss of vital substance for continued life of the neuron. Many of these diseases are associated with loss of purkinje cells.
Age of Onset:
Early-onset: 3weeks of age
Late onset: 4 years of age
Early-onset: 3weeks of age

Sex Predisposition: Any sex of animal can be affected
Clinical Course:
Clinical signs typically worsen over time
