The first case describes a 13\u2010year\u2010old boy with a 2\u2010year history of nocturnal seizures, characterized by an asymmetrical brief tonic posture followed by bilateral rapid hand shaking, but without impaired awareness. Magnetic resonance imaging revealed no abnormalities. Video electroencephalogram indicated interictal focal spikes and ictal activity 2\u2009s before clinical onset in the frontal midline area. The patient stated that he purposely shook his hands to lessen the seizure\u2010induced upper limb stiffness. The second case describes a 43\u2010year\u2010old man with a 33\u2010year history of nocturnal seizures, characterized by an asymmetric brief tonic posture, with the right hand grabbing to hold this posture, but without impaired awareness. Video electroencephalogram indicated that he voluntarily moved his right hand during the latter part of the seizures; however, no clear ictal electroencephalogram change was noted. Magnetic resonance imaging revealed a mass lesion in the right medial superior frontal gyrus. Fluorodeoxyglucose\u2010positron emission tomography and ictal single\u2010photon emission computed tomography indicated ictal focus in the mesial frontal area, as confirmed by invasive electroencephalogram and seizure freedom after surgery. Both patients had typical supplementary motor area seizures, except they could perform voluntary movements in the body parts. The co\u2010occurrence of supplementary motor area seizures and voluntary movements is clinically useful, as it may help avoid the inaccurate and misleading diagnosis of non\u2010epileptic events such as psychogenic non\u2010epileptic seizures.<\/jats:p>","DOI":"10.1002\/epd2.20047","type":"journal-article","created":{"date-parts":[[2023,3,22]],"date-time":"2023-03-22T09:49:01Z","timestamp":1679478541000},"page":"416-421","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Focal
