[question name="Lori"]  I was wondering if, in addition to the various topics that you discussed as possible causes of equine seizures ("AAEP Answerline: Seizures" in the November 1999 issue of The Horse, online at  TheHorse.com/10386), Cushing’s syndrome is a contributing factor. My gelding has the start of it, and exhibited an episode of shaking, colic, then a seizure. Is this part of Cushing’s?
