Approach to canine paroxysmal dyskinesias

The term ‘paroxysmal dyskinesia’ (PD) describes a manifestation of involuntary movement or muscle tone, which by definition is episodic in nature and self-limiting. The PDs remain poorly understood and frequently under-recognised conditions in veterinary patients. The purpose of this article is to review the basic classification and principles of recognition and diagnosis of PDs. This article introduces some of the breed-specific PDs, as well as the treatment/management options available and expected outcomes.
