Movement disorders phenomenology in focal motor seizures.

Parkinsonism Relat Disord 2018 Oct 16. Epub 2018 Oct 16.

Department of Human Neurosciences, Sapienza University of Rome, Rome, Italy; IRCSS Neuromed, Pozzilli, IS, Italy.

Introduction: Although focal motor seizures may resemble one or more movement disorders their phenomenology and prevalence remain uncertain.

Methods: To examine the extent to which focal motor seizures can present with a phenomenology fulfilling diagnostic criteria for movement disorders, 100 consecutive patients with focal motor seizures were rated by movement disorders experts, epileptologists, and general neurologists.

Results: A focal motor seizure phenomenologically manifested as a defined movement disorder in 29% of the patients from a consecutive video-EEG documented cohort as per consensus among experts: myoclonus and dystonia (10 and 9 cases, respectively) were the most common movement disorders, followed by chorea (4), stereotypies (3) myoclonus-dystonia (2), and tremor (1).

Executive impairment is associated with unawareness of neuropsychiatric symptoms in premanifest and early Huntington's disease.

Neuropsychology 2018 Nov 13;32(8):958-965. Epub 2018 Sep 13.

Monash Institute of Cognitive and Clinical Neurosciences, School of Psychological Sciences, Monash University.

Objective: Unawareness of neuropsychiatric symptoms appears to be common in Huntington's disease (HD), but the clinical correlates of unawareness are unclear. Identifying predictors of unawareness is important for improving diagnosis of neuropsychiatric symptoms, and cognitive impairment, specifically executive impairment, may be a potential important predictor of unawareness. The authors examined whether unawareness of neuropsychiatric symptoms is more common in early HD compared to premanifest HD, and whether executive task performance was associated with awareness, independent of demographic, motor or mood variables.

Heterozygous point mutations or deletions of the NKX2-1 gene cause benign hereditary chorea (BHC) or a various combinations of primary hypothyroidism, respiratory distress and neurological disorders. Deletions proximal to, but not encompassing, NKX2-1 have been described in few subjects with brain-lung-thyroid syndrome. We report on a three-generation Italian family, with 6 subjects presenting BHC and harboring a genomic deletion adjacent to NKX2-1 and including the gene MBIP, recently proposed to be relevant for the pathogenesis of brain-lung-thyroid syndrome.

A Study of Triplet-Primed PCR for Identification of CAG Repeat Expansion in the HTT Gene in a Cohort of 503 Indian Cases with Huntington's Disease Symptoms.

Mol Diagn Ther 2018 06;22(3):353-359

Department of Molecular Pathology, Metropolis Healthcare Ltd, Commercial Building A, Unit No. 409 to 416, 4th Floor, Kohinoor City, Near Kohinoor Mall, Kirol Road, Kurla-W, Mumbai, 400 070, India.

Background: Huntington's disease (HD) is an autosomal-dominant neurodegenerative disorder with an average age at onset of 40 years. It is a polyglutamine (polyQ) disorder that is caused by an increase in the number of CAG repeats in the huntingtin (HTT) gene. Genetic tests that accurately determine the number of CAG repeats are performed for confirmation of diagnosis, predictive testing of persons at genetic risk for inheriting HD, and prenatal testing.

Principles and approaches to the treatment of immune-mediated movement disorders.

Eur J Paediatr Neurol 2018 Mar 19;22(2):292-300. Epub 2017 Dec 19.

The Children's Hospital at Westmead Clinical School, Children's Hospital at Westmead, Sydney Medical School, University of Sydney, Australia; Brain and Mind Centre Westmead, University of Sydney, Australia. Electronic address:

Immune mediated movement disorders include movement disorders in the context of autoimmune encephalitis such as anti-NMDAR encephalitis, post-infectious autoimmune movement disorders such as Sydenham chorea, paraneoplastic autoimmune movement disorders such as opsoclonus myoclonus ataxia syndrome, and infection triggered conditions such as paediatric acute neuropsychiatric syndrome. This review focuses on the approach to treatment of immune mediated movement disorders, which requires an understanding of the immunopathogenesis, whether the disease is destructive or 'altering', and the natural history of disease. Factors that can influence outcome include the severity of disease, the delay before starting therapy, use of multimodal therapy and whether the course is monophasic or relapsing. Read More

Corticosteroid treatment in Sydenham's chorea.

Authors:
C Fusco C Spagnoli

Eur J Paediatr Neurol 2018 Mar 16;22(2):327-331. Epub 2017 Dec 16.

Department of Pediatrics, Child Neurology and Psychiatry Unit, Arcispedale Santa Maria Nuova, IRCCS, Viale Risorgimento 80, 42123 Reggio Emilia, Italy.

Sydenham's chorea (SC) is an immune-mediated hyperkinetic movement disorder, developing after group A Beta-hemolytic streptococcal (GABHS) infection. Aside from conventional symptomatic treatment (carbamazepine, valproate, neuroleptics), the use of steroids has also been advocated, mainly in severe, drug-resistant cases or if clinically disabling side effects develop with first line therapies. Based on the description of 5 cases followed in the Child Neurology Unit of Santa Maria Nuova Hospital in Reggio Emilia and on the available medical literature on this topic, we propose considering the use of corticosteroids therapy in children with SC, with the administration of IV methyl-prednisolone followed by oral deflazacort in severe cases and of oral deflazacort alone in mild and moderate degrees of involvement.
