 There also is some evidence that affected animals partially compensate for the condition by cognitively learning alternative methods for moving or to determine distance, and thus appear to improve because they become less accident-prone.Cerebellar abiotrophy is best known as a condition affecting Arabian horses.It has also been observed in the Curly horse, Miniature horse, the Gotland Pony, one Eriskay Pony, and possibly the Oldenburg.
