Abstract

The present paper aims to report cases of equine motor neuron disease in different breeds and ages. The main clinical signs were progressive weight loss, muscle atrophy, generalized weakness, muscle fasciculation and trembling, frequent shifting of support hindlimbs, feet under body, excessive recumbency and death. Clinical diagnosis was confirmed by histopathological studies of the spinal cord, which revealed degeneration and loss of neurons in the ventral horn, particularly cervical and lumbar intumescence. Muscle biopsy
revealed neuromuscular disorders with denervation atrophy. The progressive muscle atrophy, weakness and motor neuron degeneration are similar to those in amyotrophic lateral sclerosis, or Lou Gehrig’s disease, as described in human beings.
