There is currently no treatment for cerebellar abiotrophy, as brain cells lost by the disease cannot be regained. The condition does seem to stabilize as the horse gets older and it has been reported that some horses improve slightly over time.
A horse that suffers from cerebellar abiotrophy should not be ridden at all as their lack of coordination makes riding dangerous for both the rider and the horse. Many horses with this condition are euthanized because they do become a danger to themselves or others.
Unfortunately, there are currently no preventive measures for cerebellar abiotrophy.
