Other Terms Used
The condition in Kerry Blue Terriers is sometimes called progressive neuronal abiotrophy (PNA). Other terms used to describe the condition in dogs include cerebellar cortical atrophy and postnatal cerebellar cortical degeneration.
Cerebellar abiotrophy in horses was originally thought to be a form of cerebellar hypoplasia 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. Cerebellar hypoplasia is particularly common in cats and has similar symptoms.
There are other diseases that lead to cerebellar degeneration, but the loss of Purkinje cells is a clear way to diagnose CA, and the combination of symptoms is sufficiently unique that CA can easily be distinguished from other conditions, even in a living animal.

Famous quotes containing the word terms:
“The mystic purchases a moment of exhilaration with a lifetime of confusion; and the confusion is infectious and destructive. It is confusing and destructive to try and explain anything in terms of anything else, poetry in terms of psychology.”
—Basil Bunting (1900–1985)
