AbstractAbstract PDF
Functional movement disorder (FMD) is a type of functional neurological disorder that is common but often difficult to diagnose or manage. FMD can present as various phenotypes, including tremor, dystonia, myoclonus, gait disorders, and parkinsonism. Conducting a clinical examination appropriate for assessing a patient with suspected FMD is important, and various diagnostic testing maneuvers may also be helpful. Treatment involving a multidisciplinary team, either outpatient or inpatient, has been found to be most effective. Examples of such treatment protocols are also discussed in this review. While recognition and understanding of the disorder has improved over the past few decades, as well as the development of treatments, it is not uncommon for patients and physicians to continue to experience various difficulties when dealing with this disorder. In this review, I provide a practical overview of FMD and discuss how the clinical encounter itself can play a role in patients’ acceptance of the diagnosis. Recent neuroimaging studies that aid in understanding the pathophysiology are also discussed.

AbstractAbstract PDFSupplementary Material
Hydroxychloroquine (HCQ) has been used as an investigational drug for patients with moderate to severe coronavirus disease 2019 (COVID-19). There have been concerns of potential harms from side effects of the drug. We present a case of a 38-year-old male who was started on HCQ for COVID-19 pneumonia. He was referred for evaluation of myoclonus of all extremities, which resolved after discontinuation of HCQ. The involuntary movements were first reported after the initiation of HCQ, persisted despite improvement in inflammatory and radiologic parameters and eventually resolved after HCQ discontinuation. This supports a possible causality related to adverse drug reactions from HCQ that have not been commonly reported.

AbstractAbstract PDF

Radicular myoclonus (RM) is a kind of peripheral myoclonus exclusively related with traumatic spinal root lesion. Here we describe a case with involuntary scapular movements as a possible manifestation of RM. A 37-year-old woman without any underlying disease developedinvoluntary movements of left shoulder two days after cervical trauma. On needle electromyographic recordings, the myoclonic jerky movements were found in left serratus anterior and rhomboid major muscles, and the duration of bursts ranged from 100 to 300 ms with the irregular frequency of 1–2 Hz. Electromyography studies showed accompanying left C5 radiculopathy. Treatment with clonazepm markedly improved involuntary scapular movements.
