AIM: To compare physiological age-relatedness between dyskinesia (dystonia/choreoathetosis), dystonia and ataxia rating scale scores in healthy children. METHOD: Three movement disorders specialists quantified dyskinetic-like features in healthy children (n = 52; 4-16 years) using the Dyskinesia Impairment Scale (DIS = DIS-choreoathetosis (DIS-C) + DIS-dystonia (DIS-D)). We compared the age-related regression coefficients of the DIS with data processed from previous studies on dystonia and ataxia rating scales (Burke-Fahn-Marsden Movement and Disability Scales (BFMMS and BFMDS) and Scale for Assessment and Rating of Ataxia (SARA), International Cooperative Ataxia Rating Scale (ICARS) and Brief Ataxia Rating Scale (BARS))...

BACKGROUND: Deep brain stimulation (DBS) is an established treatment for generalized dystonia. However, the DBS device is sometimes removed owing to hardware complications. Here, we present four cases of generalized dystonia treated with radiofrequency lesioning through the DBS electrodes. CASE DESCRIPTION: The patients were three men and one woman (34 to 44 years old). They had undergone DBS for generalized dystonia. However, they subsequently developed complications, such as infection, and removal of the devices became necessary...

Runner’s dystonia (RD) is a task-specific focal dystonia of the lower limbs that occurs when running. In this retrospective case series, we present surface electromyography (EMG) and joint kinematic data from thirteen patients with RD who underwent instrumented gait analysis (IGA) at the Functional and Biomechanics Laboratory at the National Institutes of Health. Four cases of RD are described in greater detail to demonstrate the potential utility of EMG with kinematic studies to identify dystonic muscle groups in RD...

Heavy metal poisoning is a rare but important cause of encephalopathy. Manganese (Mn) toxicity is especially rare in the modern world, and clinicians’ lack of recognition of its neuropsychiatric manifestations can lead to misdiagnosis and mismanagement. We describe the case of a man who presented with recurrent episodes of confusion, psychosis, dystonic limb movement and cognitive impairment and was initially diagnosed with anti-voltage-gated potassium channel (VGKC) complex limbic encephalitis in view of previous positive autoantibodies...

OBJECTIVE: Untreated individuals with glutaric aciduria type 1 (GA1) commonly present with a complex, predominantly dystonic movement disorder (MD) following acute or insidious onset striatal damage. Implementation of GA1 into newborn screening (NBS) programmes has improved the short-term outcome. It remains unclear, however, whether NBS changes the long-term outcome and which variables are predictive. METHODS: This prospective, observational, multi-centre study includes 87 patients identified by NBS, four patients missed by NBS and three women with GA1 identified by positive NBS results of their unaffected children...

Dystonic storm or status dystonicus is a life-threatening hyperkinetic movement disorder with biochemical alterations due to the excessive muscle contractions. The medical management can require pediatric intensive care unit admission and a combination of medications while the underlying trigger is managed. Severe cases may require general anesthesia and paralytic agents with intubation and may relapse when these drugs are weaned. Deep brain stimulation of the globus pallidum has been reported to terminate dystonic storm in several pediatric cases...

Ataxias with oculomotor apraxia (AOA) belong to autosomal recessive ataxias. Their common feature is oculomotor apraxia: inability to coordinate eye movements not due to muscle weakness. Next-generation sequencing (NGS) gives unique opportunities of rare disorders diagnostics and discovering of new forms, including AOA. In 2015, AOA type 4 produced by PNKP mutations was delineated in a group of Portuguese patients. We diagnosed AOA4 in a 9-year-old boy from Byelorussian family. He presented with ataxia since 2 years and deterioration in 8 years, oculomotor apraxia, dystonic hyperkinesia, dysarthria, polyneuropathy, borderline/mildly impaired intelligence, cerebellar atrophy on MRI and moderate hypercholesterolemia...

BACKGROUND: The relationship between temporal lobe epilepsy and focal limb dystonia is a well-recognized phenomenon, yet its pathogenesis and anatomical foundation are not well understood. Here, we describe two patients with refractory focal epilepsy and contralateral focal limb dystonia whose seizures and dystonic symptoms simultaneously resolved after anterior temporal lobectomy and amygdalohippocampectomy (ATLAH). CASE DESCRIPTION: We identified two patients within the Mount Sinai Health system with improvement in dystonia after medial temporal lobectomy...

BACKGROUND: Although pallidal deep brain stimulation (GPi-DBS) is an effective treatment for dystonia, it may cause important stimulation-induced side-effects such as hypokinetic dysarthria or stuttering. However, the reasons behind the occurrence of these side-effects remain unknown. OBJECTIVE: To objectively investigate the impact of GPi-DBS on patients with dystonia on speech fluency, intelligibility, and key aspects of hyperkinetic and hypokinetic dysarthria...

Complex regional pain syndrome (CRPS) type I in stroke patients is usually known to affect the hemiplegic upper limb. We report a case of CRPS presented in an ipsilesional arm of a 72-year-old female patient after an ischemic stroke at the left middle cerebral artery territory. Clinical signs such as painful range of motion and hyperalgesia of her left upper extremity, swollen left hand, and dystonic posture were suggestive of CRPS. A three-phase bone scintigraphy showed increased uptake in all phases in the ipsilesional arm...

STUDY OBJECTIVE: Acute behavioral disturbance is a common problem for emergency medical services. We aimed to investigate the safety and effectiveness of droperidol compared to midazolam in the prehospital setting. METHODS: This was a prospective before and after study comparing droperidol to midazolam for prehospital acute behavioral disturbance, when the state ambulance service changed medications. The primary outcome was the proportion of adverse effects (airway intervention, oxygen saturation < 90%, respiratory rate < 12, systolic blood pressure < 90 mmHg, sedation assessment tool score -3 and dystonic reactions) in patients receiving sedation...

This report describes a rare case presenting with dystonic seizures due to anti-N-methyl-D-aspartate (NMDA) receptor encephalitis. The patient was an 18-year-old woman with repeated right-dominant dystonic seizures even under sedation. Single-photon emission computed tomography (SPECT) showed intense hyperperfusion of the caudate nuclei, putamen, globus pallidus, thalamus, and insula on the left side, suggesting encephalitis. Antibodies against NMDA receptors were detected in the sera and cerebrospinal fluids...

The aim of this study was to analyze the detailed characteristics of the psychiatric symptoms in patients with anti-LGI1 encephalitis. Of 16 patients, ten showed psychiatric symptoms as the initial manifestations. All 10 patients experienced mood-related symptoms. The time to immune therapy was longer in those with initial psychiatric symptoms compared to those without them. Initial manifestation of psychiatric symptoms in patients with anti-LGI1 encephalitis may be a poor prognostic factor, at least in the short term, in that it misleads both the patients and the clinicians to neglect the typically accompanied symptoms of the disease such as faciobrachial dystonic seizure, delaying the timing of immune therapy...

Oculogyric crisis (OGC) is an acute dystonic reaction, commonly seen with the administration of typical antipsychotics, and rarely reported with atypical antipsychotics. Here, we report five cases of oculogyric crisis, developed after administration of atypical antipsychotics. The first case developed OGC on quetiapine 800 mg/day and the second case on olanzapine 20 mg/day. Both the patients did not improve on adding anticholinergic agents and finally stabilized by switching to clozapine. The third case developed OGC on amisulpride 400 mg and lurasidone 40 mg/day and improved by reducing amisulpride dose to 200 mg and stopping lurasidone...

REVIEW
M Angela Cenci, Alan R Crossman
Understanding the biological mechanisms of l-dopa-induced motor complications is dependent on our ability to investigate these phenomena in animal models of Parkinson's disease. The most common motor complications consist in wearing-off fluctuations and abnormal involuntary movements appearing when plasma levels of l-dopa are high, commonly referred to as peak-dose l-dopa-induced dyskinesia. Parkinsonian models exhibiting these features have been well-characterized in both rodent and nonhuman primate species...

For the healthy motor control system, an essential regulatory role is maintaining the equilibrium between keeping unwanted motor variability in check whilst allowing informative elements of motor variability. Kinematic studies in children with generalised dystonia (due to mixed aetiologies) show that movements are characterised by increased motor variability. In this study, the mechanisms by which high motor variability may influence movement generation in dystonia were investigated. Reaching movements in the symptomatic arm of 10 patients with DYT1 dystonia and 12 age-matched controls were captured using a robotic manipulandum and features of motor variability were extracted...
