Axial myoclonus after ischemic stroke
2015
Myoclonus is an unusual manifestation of stroke.1 We report a 67-year-old woman admitted with an acute ischemic stroke in the right thalamo-capsular and hippocampal areas (figure). Becoming upright produced marked postural instability, due to an apparent reduction in cervical and dorsal axial muscle tone. EMG disclosed negative myoclonus in left upper limb and right paraspinal muscles, and both negative and positive myoclonus in left paraspinal muscles (video on the Neurology ® Web site at [Neurology.org][1]). No epileptic activity was observed on EEG.
