The condition in Kerry Blue Terriers is sometimes called progressive neuronal<unk> . Other terms used to describe the condition in dogs include<unk>  cortical atrophy and postnatal<unk>  cortical degeneration.<unk>  in horses was originally thought to be a form of<unk>  hypoplasia (CH) and was described as such in older research literature. However, it was discovered that in horses, the die-off of purkinje cells began after the animal was born, rather than occurring in utero.<unk>  hypoplasia is distinctly different in that it is a condition from a lack of these cells being formed during the development of the cerebellum. CH has been found in several species, including cats, dogs, cows and sheep. There are other diseases that lead to<unk>  degeneration, but the loss of Purkinje cells is a clear way to diagnose<unk> , and the combination of clinical signs is sufficiently unique that<unk>  can easily be distinguished from other conditions, even in a living animal.
