The Diagnosis of Neurological Disease in Horses
  by Robert N. Oglesby DVM

The nervous system is integrated with the normal function of every one of the horses body's organs. In turn proper function of the nervous system depends on the proper functioning of each of the body's organs. Diseases of the nervous system are usually first exhibited as a change in the horse's alertness, behavior, gait, and/or ability to sense the world around them. The horse may just have one of these changes or a combination of different symptoms. Primary neurologic disease in horses is a common problem and can be a diagnostic challenge because:

• The central nervous system is not easily observed and directly examined.
• Large number of similar diseases effecting the nervous system.
• No matter what the cause of the disease, the symptoms seen depend on the location of the disease. Different diseases will have similar symptoms if they effect the same location of the nervous system.

On the helpful side is that certain diseases tend to have a predilection for certain areas and certain signalment. Signalment is the circumstances, history, sex, age, breed, etc... under which the disease occurs. Localizing neurological diseases to certain areas requires a understanding of the functional regions of the nervous system.

This article will help equestrians accurately label the symptoms which is the first step to localizing the disease. Once the symptoms are accurately labeled links are provided to articles that will further help them differentiate the diseases that effect that area and ways to differentiate them. Once a list of differential diagnoses is generated an appropriate diagnostic and therapeutic regime can be planned.
