Neurology

California researchers found that "sidewinder" syndrome is associated with a variety of equine conditions and injuries.

The horse, who is currently quarantined, is experiencing ataxia, hind-end weakness and an inability to urinate. All of these are common neurologic signs associated with EHV-1.

Most EPM cases respond to treatment but a return of signs months or even years later may signal relapse, and a new round of treatment may be needed.
