Treatment

Equine Degenerative Myeloencephalopathy (EDM) currently has no specific treatment to reverse the neurological damage caused by the disease. Management primarily focuses on supportive care and minimizing progression of symptoms. This includes providing a safe environment to prevent injuries, ensuring proper nutrition and hydration, and managing any secondary complications such as infections. Regular veterinary monitoring and consultation with specialists may help optimize the horse’s quality of life and provide supportive therapies tailored to individual needs.

Prevention

Preventing Equine Degenerative Myeloencephalopathy (EDM) involves genetic testing of breeding stock to identify carriers of the mutation associated with the disease. Breeders should avoid mating carriers to reduce the risk of producing affected offspring.
