One of our soapboxes! We find many horses misdiagnosed with EPM that are being treated with compounded drugs and end up having a non diagnosed neck injury, ear ticks , THO, a primary orthopedic lesion, or, even more commonly, poor hoof balance. A blood test alone in Texas is meaningless. It must be paired with a CSF sample (fluid around the brain) to determine whether or not there is actual presence of disease. None of the compounded drugs actually work to treat EPM, although horses often look better because of rest and increased feed efficiency from the type of drugs used.
