The pathophysiology of dystonia in Wilson disease (WD) is complex and poorly understood. Copper accumulation in the basal ganglia, disrupts dopaminergic pathways, contributing to dystonia's development via neurotransmitter imbalance. Despite advances in diagnosis and management, WD with dystonia remains a challenging condition to treat.

Aim: This study aimed to explore the comparative risks for dystonia among different second-generation antipsychotics (SGAs), the influence of sex, and the relationship between the time-to-onset of dystonia and its outcomes.

Methods: We analyzed data from the Japanese Adverse Drug Event Report database from April 2004 to November 2023. Cases involving oral SGAs, excluding clozapine, were extracted.

Objective: Pathogenic variants in B-cell receptor-associated protein (BCAP31) are associated with X-linked, deafness, dystonia and cerebral hypomyelination (DDCH) syndrome. DDCH is congenital and non-progressive, featuring severe intellectual disability (ID), variable dysmorphism, and sometimes associated with shortened survival. BCAP31 encodes one of the most abundant chaperones, with several functions including acting as a negative regulator of endoplasmic reticulum (ER) calcium ion (Ca) concentration.

Movement disorders such as Parkinson's disease (PD) and cervical dystonia (CD) are associated with abnormal neuronal activity in the globus pallidus internus (GPi). Reduced firing rate and presence of spiking bursts are typical for CD, whereas PD is characterized by high frequency tonic activity. This research aims to identify the most important pallidal spiking parameters to classify these conditions.

Background: Despite efforts to visualize all the movements of tongue and oropharynx in individuals with focal movement disorders (specifically tardive dyskinesia (TD)), clinicians can miss the complete picture and additional tools may be required to reach an accurate diagnosis.

Cases: We present three cases with TD where ultrasound assisted in diagnoses. These individuals had difficulty swallowing and abnormal sensations in the tongue, which remained undiagnosed until we performed ultrasound of oropharynx which allowed for characterization of these movements.

Diagnosing Huntington's disease on the medical ward.

BMJ Case Rep

January 2025

Internal Medicine, Yale School of Medicine, New Haven, Connecticut, USA

An African American man in his early 40s with progressive gait impairment and chronic cognitive impairment initially presented to the emergency department after statements of self-harm and was hospitalised. Examination revealed notable neurological abnormalities including impaired memory recall, oral dyskinesia/choreiform movements, dystonia of the right upper extremity with drift, hyper-reflexia and spastic gait. On further evaluation, including neurology and genetics consultation and workup, a clinical diagnosis of the neurodegenerative disorder Huntington's disease (HD) was made.

Mitochondrial complex I transfers electrons from NADH (nicotinamide adenine dinucleotide) to ubiquinone, facilitating ATP synthesis via a proton gradient. Complex I defects are common among the mitochondrial diseases, especially in childhood. , located in complex I's transmembrane domain, is not directly involved in catalytic activity, but the mutations are associated with Leigh syndrome and complex I defects.

Background And Objectives: Antibody-negative autoimmune encephalitis (AE) is a form of encephalitis characterized by the absence of detectable autoimmune antibodies, despite immunological evidence. However, data on management of patients with antibody-negative AE in the intensive care unit (ICU) are limited. This study aimed to explore the characteristics and subtypes of antibody-negative AE, assess the effects of immunotherapy, and identify factors independently associated with poor functional outcomes in patients requiring intensive care.

Background: -related disorders are autosomal recessive genetic disorders characterized by movement disorders primarily including ataxia and spasticity, mainly accompanying developmental delay, seizures, and neuroimaging abnormalities. -related spectrum disorder (VSD) may better reflect the characteristics of the disease. So far, the relationship of genotype and phenotype of VSD has not been established.

Department of Neuroscience and Behavioural Sciences, School of Medicine at Ribeirão Preto, University of São Paulo, Bandeirantes Av. 3900, Ribeirão Preto, São Paulo, 14040-900, Brazil.

Neuronal Ceroid Lipofuscinosis 11 (CLN11) is an ultra-rare subtype of adult-onset Neuronal Ceroid Lipofuscinosis. Its phenotype is variable and not fully known. A 21-year-old man was evaluated in our neurogenetic outpatient clinic for early onset complex phenotype, including learning difficulties, cerebellar ataxia, cone-rod dystrophy, epilepsy, and dystonia.

The sharing of multimodal magnetic resonance imaging (MRI) data is of utmost importance in the field, as it enables a deeper understanding of facial nerve-related pathologies. However, there is a significant lack of multi-modal neuroimaging databases specifically focused on these conditions, which hampers our comprehensive knowledge of the neural foundations of facial paralysis. To address this critical gap and propel advancements in this area, we have released the Multimodal Neuroimaging Dataset of Meige Syndrome, Facial Paralysis, and Healthy Controls (MND-MFHC).

Background: Variants in the gene, encoding guanosine triphosphate cyclohydrolase, are associated with dopa-responsive dystonia (DRD) and are considered risk factors for parkinson's disease.

Methods: Comprehensive neurological assessments documented motor and non-motor symptoms in a Chinese family affected by DRD. Whole-exome sequencing (WES) was employed to identify potential mutations, with key variants confirmed by Sanger sequencing and analyzed for familial co-segregation.

Genomic characterization of Huntington's disease genetic modifiers informs drug target tractability.

Brain Commun

January 2025

Department of Pharmacology and Therapeutics, Max Rady College of Medicine, Rady Faculty of Health Sciences, University of Manitoba, Winnipeg, MB, CanadaR3E 0T6.

Huntington's disease is caused by a CAG repeat in the gene. Repeat length correlates inversely with the age of onset but only explains part of the observed clinical variability. Genome-wide association studies highlight DNA repair genes in modifying disease onset, but further research is required to identify causal genes and evaluate their tractability as drug targets.

Disgust and Other Negative Emotions in the Relationship between Mental Contamination and Post-Traumatic Stress Disorder: A Systematic Review.

Background: Mental contamination (MC) refers to feelings of internal filthiness associated with contamination obsessions. Ego-dystonic memories and thoughts can trigger MC, although it can also be activated by trauma, which is associated with the onset of post-traumatic stress disorder (PTSD). Research shows that MC, negative emotions and PTSD can occur simultaneously.

Article Synopsis
  • The globus pallidus internus (GPi) is the primary target for deep brain stimulation (DBS) in dystonia treatment, but some patients show low response rates.
  • A survey of DBS clinicians revealed that over 85% frequently use alternative targets, like the subthalamic nucleus, especially for patients who do not respond well to GPi-DBS.
  • There is a need for more research on the effectiveness of these alternative targets and better criteria for identifying nonresponding dystonia patients.

Background: Laryngeal respiratory dystonia (LRD) is diagnosed based on clinical presentation, patient history, and physical examination. Key indicators include dyspnea, desynchronized breathing patterns, and laryngoscopic findings that reveal vocal fold adduction during inspiration. Treatment for LRD remains controversial and often yields limited effectiveness.
