EPM is a serious neurological disease in horses caused by protozoan parasites that damage the brain and spinal cord, causing progressive loss of coordination and muscle function.
EPM causes progressive neurological deterioration that is frightening and physically debilitating for affected horses. Loss of coordination causes falls and injuries, while muscle weakness makes normal movement painful. The condition creates significant fear and confusion as horses lose control of their bodies. Early detection is critical to preventing severe neurological damage and the need for humane euthanasia.
