Question: My Thoroughbred gelding is 24-years-old and has Cushing's Disease and now we suspect EPM. He is being treated for both. What are the odds of a full recovery from EPM - I mean will I ever be able to ride him again?
Answer: According to current research information, around 70% of horses treated for EPM with appropriate medications and protocols will respond and return to their previous performance levels. Your horse is suffering from two separate diseases, however; so his return will depend on how readily each affected system (hormonal, or endocrine, and neurologic) is able to respond to treatments.
