The clinical characteristics and related factors of tremor in patients with epilepsy

Tremor is defined as an involuntary, rhythmical, oscillatory movement of a body part produced by either synchronous or alternating contractions of antagonist muscles [1]. As one of the most common neurological symptoms, tremor was frequently seen in patients with epilepsy (PWE). According to the Epilepsy Comorbidities and Health (EPIC) Survey, 9.3% of the respondents with epilepsy reported perceived movement disorder/tremor, more than twice as prevalent as those without epilepsy [2].
