PY - 2011 T2 - Atlas of Video-EEG Monitoring AB - Myoclonus is defined as sudden, brief, shocklike movements caused by muscle contractions (positive myoclonus) or inhibitions (negative myoclonus). It can be confusing to clinicians because of its varied clinical appearance and disparate etiologies. Patients will usually call their myoclonus “jerks,” “jolts,” “shakes,” or “spasms.” Myoclonic movements are now recognized as having many possible etiologies, anatomical sources, and pathophysiologic features, including an association with epilepsy.1 However, this relationship with epilepsy has not always been clear. This chapter discusses that relationship and distinguishes the two disorders based on differences in phenotype, physiology, and treatment.
