Treatment of Propriospinal Myoclonus at Sleep Onset
نویسندگان
چکیده
Dear Editor, Propriospinal myoclonus (PSM) is characterized by jerks arising in axial muscles that spread to more caudal and rostral segments along propriospinal pathways. PSM at sleep onset is a subtype of PSM that occurs during the sleep–awake transition and causes severe sleep-onset insomnia.1 Previous case reports have focused on the etiology and mechanism of PSM, but have not evaluated treatment responses objectively. Moreover, most treatments have only employed clonazepam.1 We present a patient with PSM at sleep onset who improved after treatment with clonazepam and add-on levetiracetam. The improvement was confirmed by serial video polysomnography (VPSG).

PROPRIOSPINAL MYOCLONUS (PSM) IS CHARACTERIZED BY FLEXION OR EXTENSION RHYTHMICARRHYTHMIC JERKS ARISING IN AXIAL MUSCLES AND SPREADING TO MORE CAUDAL AND ROSTRAL SEGMENTS. In PSM a spinal generator is believed to recruit axial and limb muscles via slowly conducting propriospinal pathways to produce the myoclonic jerks.1 Several cases of PSM have been reported and multiple sclerosis, cervical tr...

The clinical and electrophysiological features of segmental myoclonus affecting the right arm and upper trunk are described in a patient with multiple sclerosis. Electrophysiological studies suggested that the myoclonus was propagated from a generator site in the cervical cord, where lesions were found using MRI. The spread of electromyographic activity in each myoclonic jerk was slow and varia...
