BACKGROUND: Oromandibular dystonia is a movement disorder that is characterized by involuntary masticatory and/or lingual muscle contracture. Jaw closing dystonia, the most common subtype of this condition, can cause trismus and is frequently misdiagnosed as temporomandibular joint disorder or masticatory muscle tendon-aponeurosis hyperplasia. MATERIALS AND METHODS: This report describes the long-term results of 18 patients with limited mouth opening (mean maximal mouth opening: 12...

 A 70-year-old woman, residing in a nursing home, was admitted to our hospital because of cerebral hemorrhage. She had excessive sweating, a temperature above 37°C, and intermittent muscle spasm such as myoclonus, since the time of admission. We suspected that these symptoms were related to side effects caused by the milnacipran she was taking for depression, prior to hospitalization. After we discontinued milnacipran, the patient began exhibiting withdrawal symptoms such as excitement and insomnia. When we substituted milnacipran with mianserin, the withdrawal symptoms diminished and the excessive sweating and involuntary movement disappeared...

OBJECTIVE: Movement disorders are a rare manifestation of Moyamoya angiopathy (MMA). Data on prevalence and clinical presentation are warranted. Possible involuntary movements include focal motor seizures, tremor, limb-shaking transient ischemic attacks, choreiform and spastic or dystonic movement disorders. PATIENTS AND METHODS: We developed a questionnaire to systematically assess movement disorders in MMA. Patients' history of involuntary movements and their clinical presentation were assessed systematically by interview...

Cervical dystonia (CD) is a neurological disorder characterized by abnormal movements and postures of the head. The brain regions responsible for these abnormal movements are not well understood, because most imaging techniques for assessing regional brain activity cannot be used when the head is moving. Recently, we mapped brain activation in healthy individuals using functional magnetic resonance imaging during isometric head rotation, when muscle contractions occur without actual head movements. In the current study, we used the same methods to explore the neural substrates for head movements in subjects with CD who had predominantly rotational abnormalities (torticollis)...

OBJECTIVE: To evaluate the severity of wearing-off and dyskinesia in patients with complicated Parkinson disease (PD) after switching L-dopa oral therapy from a "pulsatile" administration, consisting in intermittent multiple daily small doses of the drug, to a "pulse" administration, consisting in standard oral doses given at specific interdose intervals. METHODS: Thirty-four PD patients with motor complications were monitored twice with standardized waking day motor status evaluations using the Unified Parkinson Disease Rating Scale-Motor Examination (UPDRS-ME) and the Abnormal Involuntary Movement Scale (AIMS) after switching L-dopa administration modality from "pulsatile" to "pulse...

The human body is in constant motion, from every breath that we take, to every visibly purposeful action that we perform. Remaining completely still on command is a major achievement as involuntary fluctuations in our motions are difficult to keep under control. Here we examine the noise-to-signal ratio of micro-movements present in time-series of head motions extracted from resting-state functional magnetic resonance imaging scans in 1048 participants. These included individuals with autism spectrum disorders (ASD) and healthy-controls in shared data from the Autism Brain Imaging Data Exchange (ABIDE) and the Attention-Deficit Hyperactivity Disorder (ADHD-200) databases...

OBJECTIVE: Stimulants are safe and effective medications for the treatment of ADHD. There are a number of case studies that report stimulant-induced dyskinesia. The aim of this study was to compare dyskinesia in a treated and a treatment-naive group of children with ADHD, and a healthy control group. METHOD: Children aged 6 to 18 years were involved in the study (n = 158). Diagnosis of ADHD was measured with the Mini International Neuropsychiatric Interview Kid (MINI Kid)...

Recurrent erythema multiforme (REM) is a chronic disease characterized by frequent episodes of target cutaneous lesions in an acral distribution. Conventional treatment includes systemic corticosteroids and antiviral therapy. The aim of this study was to evaluate dapsone as a potential steroid sparing-agent for the treatment of REM after a failed trial of at least one antiviral therapy (acyclovir, famciclovir, or valacyclovir). A retrospective chart review was conducted on thirteen patients with a diagnosis of REM who underwent treatment with dapsone after failing at least one antiviral therapy...

BACKGROUND: Myoclonus is a clinical sign characterized by sudden, brief jerky, shock-like involuntary movements of a muscle or group of muscles. Dystonia is defined as a syndrome of sustained muscle contractions, frequently causing twisting and repetitive movements or abnormal postures. Cases of myoclonus or dystonia secondary to a structural lesion in the cerebellum have been reported. However, there has never been a reported case of combined myoclonus and dystonia secondary to a cerebellar lesion...

PURPOSE: Nitrous oxide (N2O) is neurotoxic by interfering with vitamin B12 bioavailability. The clinical picture is indistinguishable to that of subacute combined degeneration (SCD). A movement disorder might occur though it is not a characteristic feature. We report a patient with N2O-induced SCD, exhibiting a combination of different involuntary movements. CASE REPORT: A 20-year-old woman presented with one month of progressive unsteady gait, involuntary movements and tingling sensation in a stocking-glove distribution...

Drug-induced parkinsonism (DIP) is classically described as acute/subacute, bilateral symmetric syndrome in which tremor is infrequent compared to Parkinson's disease. Most DIP cases are caused by classic (CN) and second-generation neuroleptics (SN), and calcium channel blockers (CCB). We evaluated potentially distinctive demographic and clinical features in DIP among different drug classes. This was a prospective study of reversible DIP related to single selected drugs on each class. Baseline assessment included demographic, clinical data, and scales for staging, severity of motor signs of parkinsonism, tremor, and other involuntary movements...

REVIEW
Mohammad Obadah Nakawah, Eugene C Lai
Strokes, whether ischemic or hemorrhagic, are among the most common causes of secondary movement disorders in elderly patients. Stroke-related (vascular) movement disorders, however, are uncommon complications of this relatively common disease. The spectrum of post-stroke movement disorders is broad and includes both hypo- and hyperkinetic syndromes. Post-stroke dyskinesias are involuntary hyperkinetic movements arising from cerebrovascular insults and often present with mixed phenotypes of hyperkinesia which can sometimes be difficult to classify...

Heavy drinking contributes to involuntary body movements such as akathisia. Quetiapine has been shown to alleviate symptoms of akathisia; however, its efficacy in the alcohol dependent population is not well established. Thus, we aimed to identify efficacy of Quetiapine in treating akathisia in very heavy drinking alcohol dependent patients. 108 male and female heavy alcohol consuming study participants received 13 weeks of Quetiapine XR. Drinking history (Timeline Followback, TLFB), depression (Montgomery-Asberg Depression Rating Scale, MADRS), and movement (Barnes Akathisia Scale, BARS) measures were collected at baseline (0 W), week 6 (6 W), and week 12 (12 W)...

BACKGROUND: Dystonia is characterised by involuntary movements (twisting, writhing and jerking) and postures. Secondary dystonias are described as a heterogeneous group of disorders with both exogenous and endogenous causes. There is a growing body of literature on the effects of deep brain stimulation (DBS) surgery on the motor function in childhood secondary dystonias, however research on cognitive function after DBS is scarce. METHODS: Cognitive function was measured in a cohort of 40 children with secondary dystonia following DBS surgery using a retrospective repeated measures design...

Optokinetic nystagmus (OKN) is an involuntary eye movement responsible for stabilizing retinal images in the presence of relative motion between an observer and the environment. Fully understanding the development of OKN requires a neurally plausible computational model that accounts for the neural development and the behavior. To date, work in this area has been limited. We propose a neurally plausible framework for the joint development of disparity and motion tuning in the visual cortex and of optokinetic and vergence eye-movement behavior...

BACKGROUND: Autosomal dominant congenital mirror movements (CMM) is a neurodevelopmental disorder characterized by early onset involuntary movements of one side of the body that mirror intentional movements on the contralateral side; these persist throughout life in the absence of other neurological symptoms. The main culprit genes responsible for this condition are RAD51 and DCC. This condition has only been reported in a few families, and the molecular mechanisms linking RAD51 mutations and mirror movements (MM) are poorly understood...

Mitochondrial oxidative phosphorylation (OXPHOS) disorders accounts for a variety of neuromuscular disorders in children. In this study mitochondrial respiratory chain enzymes were assayed in muscle tissue in a large cohort of children with varied neuromuscular presentations from June 2011 to December 2013. The biochemical enzyme deficiencies were correlated with the phenotypes, magnetic resonance imaging, histopathology and genetic findings to reach a final diagnosis. There were 85 children (mean age: 6.9±4...

BACKGROUND: Compulsive movements, complex tics and stereotypies are frequent, especially among patients with autism or psychomotor retardation. These movements can be difficult to characterize and can mimic other conditions like epileptic seizures or paroxysmal dystonia, particularly when abnormal breathing and cerebral hypoxia are induced.

Abnormal involuntary movements often improve in response to anti-dopaminergic drugs. In contrast to classic neuroleptics that block dopamine receptors, drugs that deplete presynaptic dopamine by blocking vesicular monoamine transporter type 2 (VMAT2) seem to be safer and have little or no risk of tardive dyskinesia. This is one reason why there has been a recent emergence of novel VMAT2 inhibitors. Areas Covered: Since the approval of tetrabenazine, the classic VMAT2 inhibitor, in the treatment of chorea associated with Huntington disease (HD), other VMAT2 inhibitors (e...
