Apparently,as the article states,many of our horses have been exposed to EPM,but when their immunity is compromised due to stress or illness,as was the case with my horse,that is often when it manifests itself.(My horse had been dangerously sick with a bacterial infection prior to the EPM event.)In over 35 years of horse ownership,I never experienced something this devastating before and I hope and pray I never do again. Thankfully,after a lot of expensive medication and much hard work,my horse is back to his old,playful self. I credit a great deal to him and his courage and intelligence. He never once protested any of the medications,tests or exercises and even when he fell down,he never gave up. In fact,for several days prior to showing definitive symptoms,he would whinny to me each time he saw me,as though trying to tell me something was wrong. So,recovery takes a combination of factors,but there is always hope!
