Chromosomal aberrations are rare but known causes of movement disorders, presenting with broad phenotypes in which dystonia may be predominant. During the investigation of such cases, chromosomal studies are not often considered as a first approach. In this article, the authors describe a family affected by a generalized form of dystonia, evolving from a focal phenotype, for which a new X chromosome large duplication was found to be the likely causative, therefore highlighting the role of such studies when facing complex movement disorders.

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.

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.
