Several non-epileptic disorders may cause episodic and paroxysmal symptoms that resemble epilepsy and they must be considered in the differential diagnosis. Some of these disorders are discussed in the present review: vasovagal, vasomotor and cardiac syncopes, breath holding spells. Among the sleep disorders, parasomnias, nightmares and the benign neonatal sleep myoclonus are mentioned. Migraine with aura, alternating hemiplegia and benign vertigo of childhood are probably related disorders. Benign myoclonus of early infancy, paroxysmal choreoathetoses and pseudoepileptic or hysterical seizures are further non-epileptic attack disorders to be considered in the differential diagnosis.

The muscular tinnitus due to an extrinsic auricular myoclonus is an extremely rare disorder which demonstrates a semirhythmic involuntary movement of the ear. We report a 33-year-old man with clicking tinnitus caused by focal myoclonic jerks of bilateral posterior auricularis muscle and bilateral temporalis muscle. This muscular tinnitus persisted except for when he was sleeping or breath holding. His symptom responded poorly to medical therapy but was controlled by botulinum toxin type A injection under electromyography monitoring with favorable outcome. Previous reports of this condition and possible therapeutic approaches are discussed.
