What causes equine degenerative myeloencephalopathy?
Equine neuroaxonal dystrophy (eNAD) and equine degenerative myeloencephalopathy (EDM) result from abnormalities of specific neurons in the brainstem and spinal cord. Research suggests that eNAD is the underlying basis for EDM, which is the more advanced form of the disease.
What is Myeloencephalopathy?
Equine herpesvirus myeloencephalopathy (EHM) is another name for the neurologic disease associated with equine herpesvirus (EHV) infec- tions. Neurological signs appear as a result of damage to blood vessels in the brain and spinal cord associated with EHV infection.
What can cause neurological problems in horses?
Many diseases can affect horses’ central nervous systems, but four of the most common disorders are cervical vertebral stenotic myelopathy (CSM), equine protozoal myeloencephalitis (EPM), equine degenerative myeloencephalopathy (EDM), and equine herpesvirus-1 myeloencephalopathy (EHM).
What are the symptoms of EMS in horses?
One of the most common signs of EMS is the development of abnormal fat deposits (pockets/bulges/pads), usually seen around the crest, behind the shoulder, the rump (especially at the tail head) and above the eyes. Difficulty losing weight. Recurring episodes of acute laminitis. Increased drinking and urination.
Can horses recover from EDM?
Animals predisposed to EDM or with a clinical diagnosis of EDM should receive oral alpha-tocopherol acetate supplementation. Improvement in clinical signs may be seen following long-term treatment, but in general, the prognosis for complete recovery is poor.
Can a horse recover from EHV?
In most cases, horses exposed to EHV-1 will develop a fever and possibly nasal discharge and then go on to recover. However, the neurologic EHM strain has a high mortality rate of 30-50%. Recovery time can vary from several days to more than a year.
Can ataxia be cured in horses?
RECOVERY CHANCES. THE prognosis for ataxia is variable, depending on the diagnosis. Stinging nettle-induced ataxia can resolve quickly and fully once the horse is removed from the nettles, sedated and provided with appropriate anti-inflammatories.
Why is my horse staggering?
“The most common neurologic problem equine veterinarians see in the United States is an abnormal gait,” Dr. Sellon says. “Affected horses are usually ataxic and weak, meaning that they walk with a staggering or drunken type of gait. They may drag their toes, stumble frequently or sway back and forth when they walk.”

What is degenerative myelopathy (DM)?
Degenerative Myelopathy – Disease Basics. Another key feature of DM is that it is not a painful disease. Degenerative myelopathy is a devastating disease causing progressive paralysis in a large number of dog breeds. New research has identified a gene that is associated with a major increase in risk of the disease.
