Plain-English summary

In this case, a dog was diagnosed with a type of epilepsy that caused symptoms similar to a condition known as canine idiopathic head tremor syndrome (CIHTS), which involves uncontrolled head movements. The dog's brain activity showed a specific pattern that is also seen in a serious human condition called Lennox-Gastaut syndrome. Over two years, the dog was treated with a medication called phenobarbitone to help manage the seizures. The report suggests that this treatment was effective in controlling the dog's symptoms.

Abstract

Canine idiopathic head tremor syndrome (CIHTS) represents a benign condition characterized by episodic, uncontrolled movement of the head. Even though the condition might be an expression of a partial motor epilepsy, to date, there is a limited number of studies describing the electroencephalographic features. In this report, we describe the case of a dog diagnosed with partial motor epilepsy resembling CIHTS symptomatology, a new slow spike–wave complex pattern similar to that of Lennox–Gastaut syndrome in humans identified on electroencephalographic examination. We also studied the efficacy of phenobarbitone therapy over a period of two years.
