Can a horse fully recover from EPM?

The sooner treatment begins, the better the horse’s chances are for recovery. Sixty to 70 percent of EPM cases aggressively treated show significant or complete reversal of symptoms. Many horses are able to return to normal activity.

In fact, 80% to 90% recover completely. Over all 10% to 20% of horses will relapse. Horses that have mild cases tend to have a lower rate of relapse. If your horse has a severe case of EPM, the prognosis is not as good, but this can vary from case to case.

What are signs of EPM?

Learn to Recognize the Symptoms of EPM

  • Ataxia (incoordination), spasticity (stiff, stilted movements), abnormal gait or lameness.
  • Incoordination and weakness which worsens when going up or down slopes or when head is elevated.

Can you ride a horse that has EPM?

A Horses that recover completely can return to their original intended use. For horses that do recover, the improvement is based on the initial severity of the clinical signs (see box). However, not all horses that “improve” according to the clinical scale are able to be safely ridden again.

How do I know if my horse has EPM?

How is equine protozoal myeloencephalitis ( EPM ) diagnosed?

Therefore, EPM is diagnosed based on a combination of (1) a thorough neurologic examination, (2) evaluation of serum and/or cerebrospinal fluid (CSF) for the presence of antibodies to S. neurona and/or N. hughesi, and (3) the elimination of other neurological disorders.

What does the EPM society do for horses?

The EPM Society endeavors to contribute to a greater understanding of equine protozoal myeloencephalitis, encourage cooperative EPM research, promote awareness of current EPM research and new developments in the field, and evaluate and disseminate guidelines for the diagnosis, treatment, and prevention of EPM.

What does a positive blood test for EPM mean?

A positive blood test only means the horse has been exposed to the parasite, not that it has or will develop clinical disease. Prompt, accurate diagnosis is essential and treatment should begin immediately. The sooner treatment begins, the better the horse’s chances are for recovery.
