A retrospective study of nineteen ataxic horses.

This paper presents a retrospective study of 19 horses that showed ataxic conditions and were admitted to the College of Veterinary Medicine of the University of Montreal between January 1985 and December 1988.

Research Context

• The research is based on a retrospective analysis of 19 horses that were displaying ataxic symptoms, admitted to the Veterinary Medicine College at the University of Montreal from January 1985 to December 1988.
• Ataxia, in general, is a condition of lack of voluntary coordination of muscle movements. This can manifest in various ways in horses, leading to a variety of health problems requiring medical attention.

Findings of the Study

• The study found that out of the 19 horses, 11 were diagnosed with cervical vertebral malformation. This condition is often hereditary and results in an abnormal formation of the cervical vertebrae, leading to neurological issues.
• Four horses were found to be suffering from equine degenerative myeloencephalopathy, a progressive neurological disorder that affects the horse’s spinal cord and brain.
• Two cases of equine protozoal myeloencephalitis were identified, which is a serious neurological disease that can cause severe disability in horses. It is typically caused by a protozoan parasite.
• One case each of vertebral osteomyelitis and intervertebral disc protrusion were diagnosed. Vertebral osteomyelitis is an infection of the spinal bones, while intervertebral disc protrusion is a condition where the spinal disc protrudes beyond its normal position, potentially causing nerve compression.

Diagnostic Methods

• The diagnosis of ataxia in horses, as per this study, requires comprehensive medical assessments. These often include neurological examinations to identify potential issues with the horse’s nervous system.
• Radiographic examinations were also part of the diagnostic process. These provide images of the horse’s internal structures and can help detect abnormalities in the spinal cord or brain.
• Myelographic examinations were used to create detailed images of the spinal cord and surrounding structures.
• Laboratory examinations provided further insight into the horse’s overall health and helped detect any underlying issues that could be contributing to the ataxic behaviour.
