Safety of transcranial direct current stimulation in a patient with deep brain stimulation electrodes.

Arq Neuropsiquiatr 2019 Mar;77(3):174-178

Universidade de Brasília, Departamento de Ciências Fisiológicas, Instituto de Biologia, Brasília DF, Brasil.

Background: Transcranial direct current stimulation (tDCS) has been investigated in movement disorders, making it a therapeutic alternative in clinical settings. However, there is still no consensus on the most appropriate treatment protocols in most cases, and the presence of deep brain stimulation (DBS) electrodes has been regarded as a contraindication to the procedure. We recently studied the effects of cerebellar tDCS on a female patient already undergoing subthalamic nucleus deep brain stimulation (STN-DBS) for generalized dystonia. Read More

Clinical approach to tremor in children.

Parkinsonism Relat Disord 2019 Mar 23. Epub 2019 Mar 23.

Department of Neurological Sciences, University of Nebraska Medical Center, Omaha, NE, 68198, United States. Electronic address:

Pediatric Movement Disorders encompass a very large and complex group of diseases, among which Tremor is one of the least studied. Evaluation of tremors in kids carries significant challenges, in particular the fact that many tremor etiologies have other associated movement disorders that make tremor identification more difficult. Also, it is sometimes difficult to differentiate tremors from other shaking disorders. Read More

Current therapies and therapeutic decision making for childhood-onset movement disorders.

Mov Disord 2019 Mar 28. Epub 2019 Mar 28.

Kids Neuroscience Centre, The Kids Research Institute at the Children's Hospital at Westmead, Brain and Mind Centre, Faculty of Medicine and Health, University of Sydney, Westmead, NSW, Australia.

Movement disorders differ in children to adults. First, neurodevelopmental movement disorders such as tics and stereotypies are more prevalent than parkinsonism, and second, there is a genomic revolution which is now explaining many early-onset dystonic syndromes. We outline an approach to children with movement disorders starting with defining the movement phenomenology, determining the level of functional impairment due to abnormal movements, and screening for comorbid psychiatric conditions and cognitive impairments which often contribute more to disability than the movements themselves.

Unique finding in congenital muscular torticollis: Clinic screening on the neck of one day old neonate and ultrasonographic imaging from birth through 3 years of follow-up.

Medicine (Baltimore) 2019 Mar;98(11):e14794

Department of Pediatric Orthopaedics, Shenzhen Children's Hospital, Shenzhen.

Congenital muscular torticollis (CMT) is a common musculoskeletal abnormality in children, which has been characterized by unclarified pathological changes in the sternocleidomastoid muscle (SCM) and various hypothetical etiologies. There are 2 main hypothetical etiologies for CMT in the literature: 1 infers that CMT may represent the sequela of an intrauterine or perinatal compartment syndrome, and the other regard CMT as a maldevelopment of the fetal SCM.To better understand the etiopathogenesis of CMT, we screened the necks of 1-day-old newborns that may potentially have CMT for evidence of SCM trauma or tumor.

Probabilistic mapping of the antidystonic effect of pallidal neurostimulation: a multicentre imaging study.

Brain 2019 Mar 8. Epub 2019 Mar 8.

Julius-Maximilians-University Würzburg, Department of Neurology, Germany.

Deep brain stimulation of the internal globus pallidus is a highly effective and established therapy for primary generalized and cervical dystonia, but therapeutic success is compromised by a non-responder rate of up to 25%, even in carefully-selected groups. Variability in electrode placement and inappropriate stimulation settings may account for a large proportion of this outcome variability. Here, we present probabilistic mapping data on a large cohort of patients collected from several European centres to resolve the optimal stimulation volume within the pallidal region. Read More

The role of sensory information in the pathophysiology of focal dystonias.

Nat Rev Neurol 2019 Apr;15(4):224-233

IRCCS Neuromed, Pozzilli, Italy.

Over the past few decades, abnormalities in sensory functions, such as tactile, proprioceptive and nociceptive processing, have been increasingly recognized in patients with focal dystonias. In this Review, we ask whether sensory system abnormalities are specific to particular types of dystonia, whether a causal link exists between sensory alterations and dystonic motor activity and how mechanisms underlying the sensory abnormalities fit in with the proposed 'network model' of dystonia. We suggest that alterations in the various sensory modalities participate at three different levels in the pathophysiological cascade that leads to dystonia: a background level that predisposes individuals to dystonia, a disease-related level that is evident only when dystonia becomes manifest and a causative level that triggers dystonia.

Dystonic crises in dopa-responsive dystonia induced by energy drinks.

Pract Neurol 2019 Jan 30. Epub 2019 Jan 30.

Alfred Hospital, Melbourne, Victoria, Australia.

We present an interesting case of recurrent dystonic crises in dopa-responsive dystonia (DRD) likely induced by excessive consumption of aspartame-containing products, in particular sugar-free energy drinks. This has a strong practical value as acute presentations to the emergency department can be avoided in these susceptible individuals. Usual medical and dietary advice in the treatment of DRD would include the avoidance of high-dose phenylalanine-containing products, and to this we would advocate the avoidance of high-dose aspartame-containing products.

How Do I Evaluate and Inject for Writer's Cramp?

Authors:
Santiago Catania

Mov Disord Clin Pract 2018 Nov-Dec;5(6):663. Epub 2018 Nov 8.

Department of Clinical Neurophysiology The National Hospital for Neurology and Neurosurgery London United Kingdom.

Writer's cramp is a disabling focal dystonia, often accompanied by tremor, for which botulinum toxin injections are now the therapy of choice. However, the success of this treatment relies on the correct clinical selection of muscles responsible for the dystonic movements and the subsequent accurate administration of botulinum toxin into what are often very small and difficult to palpate muscles. In order to obtain the best possible outcomes, and to minimize side effects, it is necessary to use guidance from ultrasound or electromyography (EMG). Read More

Central Effects of Botulinum Neurotoxin-Evidence from Human Studies.

Toxins (Basel) 2019 Jan 6;11(1). Epub 2019 Jan 6.

Department of Neurology and Clinical Neurophysiology, Augsburg University, Stenglinstrasse 2, D-86156 Augsburg, Germany.

For more than three decades, Botulinum neurotoxin (BoNT) has been used to treat a variety of clinical conditions such as spastic or dystonic disorders by inducing a temporary paralysis of the injected muscle as the desired clinical effect. BoNT is known to primarily act at the neuromuscular junction resulting in a biochemical denervation of the treated muscle. However, recent evidence suggests that BoNT's pharmacological properties may not only be limited to local muscular denervation at the injection site but may also include additional central effects.

"Spooning": A Subtle Sign of Limb Dystonia.

Tremor Other Hyperkinet Mov (N Y) 2018 3;8:607. Epub 2018 Dec 3.

Department of Neurology, Yale School of Medicine, Yale University, New Haven, CT, USA.

Background: The diagnosis of dystonia can be clinically challenging due to its heterogeneous presentation; essential tremor (ET) is a more common neurological disorder, but may be mimicked by other movement disorders, including dystonia, leading to misdiagnosis.

Phenomenology Shown: In three patients with hand tremor, two with prior diagnoses of ET, we present examples of "spooning" of the hands, characterized by wrist flexion and metacarpophalangeal hyperextension.

Educational Value: Subtle dystonic features such as "spooning" may be present during the evaluation of patients with tremor and aid in the diagnosis of dystonia. Read More

Distinct roles of brain activity and somatotopic representation in pathophysiology of focal dystonia.

Hum Brain Mapp 2019 Apr 20;40(6):1738-1749. Epub 2018 Dec 20.

Department of Advanced Neuroimaging, Integrative Brain Imaging Center (IBIC), National Center of Neurology and Psychiatry, Tokyo, Japan.

Two main neural mechanisms including loss of cortical inhibition and maladaptive plasticity have been thought to be involved in the pathophysiology of focal task-specific dystonia. Such loss of inhibition and maladaptive plasticity likely correspond to cortical overactivity and disorganized somatotopy, respectively. However, the most plausible mechanism of focal task-specific dystonia remains unclear. Read More

Stereotactic Lesioning of the Thalamic Vo Nucleus for the Treatment of Writer's Cramp (Focal Hand Dystonia).

Front Neurol 2018 26;9:1008. Epub 2018 Nov 26.

Department of Neurodegenerative Disorders Research, Graduate School of Medical Sciences, Institute of Biomedical Sciences, Tokushima University, Tokushima, Japan.

Writer's cramp (focal hand dystonia) is a sporadic focal dystonia that affects a specific part of the upper limb causing excessive co-contraction of antagonistic muscles. It usually presents as a task-specific dystonia, including, among others, writing of a character or playing a musical instrument. Although treatments for writer's cramp exist, medical therapy often results in unsatisfactory outcomes in patients with this type of dystonia. Read More

Reduced Frequency of Ipsilateral Express Saccades in Cervical Dystonia: Probing the Nigro-Tectal Pathway.

Tremor Other Hyperkinet Mov (N Y) 2018 16;8:592. Epub 2018 Nov 16.

School of Engineering, Trinity College Dublin, The University of Dublin, Dublin, IE.

Background: Cervical dystonia is a hyperkinetic movement disorder of unknown cause. Symptoms of cervical dystonia have been induced in animals in which the integrity of the nigro-tectal pathway is disrupted, resulting in reduced inhibition of the deep layers of the superior colliculus. This same pathway is believed to play a critical role in saccade generation, particularly visually guided, express saccades. Read More

The neurological phenotype of developmental motor patterns during early childhood.

Brain Behav 2019 Jan 28;9(1):e01153. Epub 2018 Nov 28.

Department of Pediatrics, Beatrix Children's Hospital, University Medical Center Groningen, Groningen, The Netherlands.

Introduction: During early childhood, typical human motor behavior reveals a gradual transition from automatic motor patterns to acquired motor skills, by the continuous interplay between nature and nurture. During the wiring and shaping of the underlying motor networks, insight into the neurological phenotype of developmental motor patterns is incomplete. In healthy, typically developing children (0-3 years of age), we therefore aimed to investigate the neurological phenotype of developmental motor patterns. Read More

Spatial Integration of Somatosensory Inputs during Sensory-Motor Plasticity Phenomena Is Normal in Focal Hand Dystonia.

Neural Plast 2018 10;2018:4135708. Epub 2018 Oct 10.

IRCCS Centro Neurolesi "Bonino Pulejo", Messina, Italy.

Background: Surround inhibition is a system that sharpens sensation by creating an inhibitory zone around the central core of activation. In the motor system, this mechanism probably contributes to the selection of voluntary movements, and it seems to be lost in dystonia To explore if sensory information is abnormally processed and integrated in focal hand dystonia (FHD) and if surround inhibition phenomena are operating during sensory-motor plasticity and somatosensory integration in normal humans and in patients with FHD We looked at the MEP facilitation obtained after 5 Hz repetitive paired associative stimulation of median (PAS M), ulnar (PAS U), and median + ulnar nerve (PAS MU) stimulation in 8 normal subjects and 8 FHD. We evaluated the ratio MU/(M + U) ∗ 100 and the spatial and temporal somatosensory integration recording the somatosensory evoked potentials (SEPs) evoked by a dual nerve input. Read More
