Research Insights on Theiler’s Disease and Equine Motor Neuron Disease with Dr Tom Divers

In the first episode of a three-part series on equine neurology, Dr. Bart Barber and Rood & Riddle neurologist Dr. Steve Reed welcome Dr. Tom Divers from Cornell University to discuss Theiler’s disease, or equine serum hepatitis, and equine motor neuron disease (EMND).
Dr. Divers, a leading expert in equine internal medicine and neurology, shares insights into the research on both conditions. Theiler’s disease is a viral infection that can cause acute hepatitis in adult horses, while EMND is a neurodegenerative disorder characterized by weakness and muscle atrophy, often linked to limited pasture access or inadequate vitamin E intake.
The discussion highlights the ongoing efforts to uncover the underlying mechanisms of these diseases and how research has improved early detection and treatment options. This episode underscores the vital role of research in equine health and sets the stage for further exploration of other neurological conditions in the series.
