OBJECTIVE: To evaluate whether early folic acid or multivitamin supplementation during pregnancy prevents diagnosis of hyperkinetic disorders (HKD), treatment for attention deficit hyperactivity disorder (ADHD), and ADHD-like behaviors reported by parents participating in the DNBC for children at age 7. METHODS: HKD diagnosis and ADHD medication use data were obtained from the Danish National Hospital, Central Psychiatric and Pharmaceutical registers. We estimated hazard ratios (HRs) for HKD diagnosis and ADHD medication use and risk ratios (RRs) for parent-reported ADHD behavior collected with the Strength and Difficulties Questionnaire (SDQ), comparing children whose mothers took folic acid or multivitamin supplements early in pregnancy defined as starting periconceptionally (4 weeks prior to their last menstrual period (LMP)) through 8 weeks after their LMP (4-8 weeks), to children whose mothers indicated no supplement use for the same entire period...

Adenylyl cyclases (ACs) generate the second messenger cAMP from ATP. Mammalian cells express nine transmembrane AC (mAC) isoforms (AC1-9) and a soluble AC (sAC, also referred to as AC10). This review will largely focus on mACs. mACs are activated by the G-protein Gαs and regulated by multiple mechanisms. mACs are differentially expressed in tissues and regulate numerous and diverse cell functions. mACs localize in distinct membrane compartments and form signaling complexes. sAC is activated by bicarbonate with physiologic roles first described in testis...

AIM: Although birth asphyxia is a major risk factor for neonatal and childhood morbidity and mortality, it has not been investigated much in relation to attention deficit hyperactivity disorder (ADHD). We examined if birth asphyxia measured by the pH of the blood in the umbilical artery cord was associated with childhood ADHD. METHOD: A population-based cohort of 295,687 children born in Finland between1991-2002 was followed until 31 December 2007. ADHD was identified by the International Classification of Diseases, tenth edition, as a diagnosis of hyperkinetic disorder...

REVIEW
Mark Lowrie, Laurent Garosi
Paroxysmal dyskinesias (PDs) are a group of hyperkinetic movement disorders characterised by circumscribed episodes of disturbed movement, superimposed on a background state in which such abnormality is absent. There is no loss of consciousness. Episodes can last seconds, minutes or hours, and the beginning and end of the movement disturbance are abrupt. Neurological examination is typically normal between episodes. PDs are associated with a broad spectrum of clinical presentations, encompassing various aetiologies...

Monitoring the fetal behavior does not only have implications for acute care but also for identifying developmental disturbances that burden the entire later life. The concept, of "fetal programming", also known as "developmental origins of adult disease hypothesis", e.g. applies for cardiovascular, metabolic, hyperkinetic, cognitive disorders. Since the autonomic nervous system is involved in all of those systems, cardiac autonomic control may provide relevant functional diagnostic and prognostic information...

REVIEW
Giovanni Cossu, Carlo Colosimo
A movement disorder emergency has been defined by Fahn and Frucht as "any neurological disorder evolving acutely or subacutely, in which the clinical presentation is dominated by a primary movement disorder, and in which failure to accurately diagnose and manage the patient may result in significant morbidity or even mortality." In this review, we discuss the most common situations in which hyperkinetic movement disorders, including chorea, ballism, dystonia, myoclonus, tics, as well as psychogenic disorders, can present as emergencies...

BACKGROUND: Cohort studies often report findings on children with Attention Deficit Hyperactivity Disorder (ADHD) but may be biased by self-selection. The representativeness of cohort studies needs to be investigated to determine whether their findings can be generalised to the general child population. The aim of the present study was to examine the representativeness of child ADHD in the Norwegian Mother and Child Cohort Study (MoBa). METHODS: The study population was children born between January 1, 2000 and December 31, 2008 registered with hyperkinetic disorders (hereafter ADHD) in the Norwegian Patient Registry during the years 2008-2013, and two groups of children with ADHD were identified in: 1...

INTRODUCTION: The diagnosis aceruloplasminemia is usually made in patients with advanced neurological manifestations of the disease. In these patients prognosis is poor, disabilities are severe and patients often die young. The aim of our study was to facilitate recognition of aceruloplasminemia at a disease stage at which treatment can positively influence outcome. Currently, the neurological phenotype of aceruloplasminemia has been mainly described in Japanese patients. This 'classical' phenotype consists of cerebellar ataxia, hyperkinetic movement disorders and cognitive decline...

OBJECTIVE: Benign Essential Blepharospasm (BEB) and hemifacial spasm (HFS) are the most common hyperkinetic movement disorders of facial muscles. Although similar in clinical presentation different pathophysiological mechanisms are assumed. Botulinum Neurotoxin (BoNT) is a standard evidence-based treatment for both conditions. In this study we aimed to assess grey matter microstructural differences between these two groups of patients and compared them with healthy controls. In patients we furthermore tracked the longitudinal morphometric changes associated with BoNT therapy...

Cerebrovascular diseases are one of the most common causes of secondary movement disorders. Hypokinetic or hyperkinetic movement disorders may occur after an ischemic or hemorrhagic stroke, either immediately or thereafter. Such disorders are also known to be caused by diffuse leukoaraiosis, vascular malformations and dural fistulas in the basal ganglia or other brain regions. Area covered: The aim of this review was to describe movement disorders secondary to cerebrovascular diseases, and highlight their pivotal pathophysiological aspects, clinical features, diagnostic criteria and therapeutic options...

BACKGROUND: Chorein, a protein encoded by VPS13A (vacuolar protein sorting-associated protein 13A), is defective in chorea acanthocytosis, a rare disease characterized by acanthocytosis of red blood cells and neuronal cell death with progressive hyperkinetic movement disorder, cognitive dysfunction, behavioral abnormalities and chronic hyperkalemia. Chorein is highly expressed in ZF rhabdomyosarcoma cells and counteracts apoptosis of those cells. Chorein is effective in part by interacting with and fostering stimulation of phosphoinositide-3-kinase (PI3K)-p85-subunit...

BACKGROUND: Cervical dystonias have a variable presentation and underlying etiology, but collectively represent the most common form of focal dystonia. There are a number of known genetic forms of dystonia (DYT1-27); however the heterogeneity of disease presentation does not always make it easy to categorize the disease by phenotype-genotype comparison. CASE PRESENTATION: In this report, we describe a 53-year-old female who presented initially with hand tremor following a total hip arthroplasty...

BACKGROUND: Deutetrabenazine, an inhibitor of vesicular monoamine transporter type 2 (VMAT2) depletes presynaptic dopamine and is useful in the treatment of hyperkinetic movement disorders. This study explored the safety, tolerability, and preliminary efficacy of deutetrabenazine in adolescents with moderate-to-severe tics associated with Tourette syndrome (TS). METHODS: In this open-label study of 12-18-year-old patients with TS-related tics, deutetrabenazine was titrated up to 36 mg/day over 6 weeks to adequately suppress tics without bothersome adverse effects (AEs), followed by maintenance at optimal dose for 2 weeks...

OBJECTIVE: Functional or psychogenic movement disorders (FMD) present a diagnostic challenge. To diagnose FMD, clinicians must have experience with signs typical of FMD and distinguishing features from other hyperkinetic disorders. The aim of this study was to clarify the decision-making process of expert clinicians while diagnosing FMD, myoclonus, and tics. METHODS: Thirty-nine movement disorders experts rated 60 patients using a standardized web-based survey resembling clinical practice...

Hyperkinetic movement disorders such as tremors are not uncommon in patients with multiple sclerosis (MS). The classical feature is intention tremor, whereas rest tremors appear not to occur. Treatment is mainly invasive, with options of Gamma Knife surgery, thalamotomy or deep brain stimulation depending on individual circumstances. Deep brain stimulation is the only option for patients who require a bilateral intervention. All treatment recommendations have only low evidence. Tremors can also be cured spontaneously by a subsequent strategic MS lesion...

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...
