A Retrospective Survey-based Multicenter Study to Delineate the Molecular and Phenotypic Spectrum of Epilepsy-dyskinesia Syndromes
Source: ClinicalTrials.gov · Last updated 18 Mar 2026
Brief summary (registry, in English)
The Epilepsy-Dyskinesia Study aims to advance the understanding of the clinical and molecular spectrum of epilepsy-dyskinesia syndromes, monogenic diseases that cause both movement disorders and epilepsy. Addressing challenges in rare disease research -such as small, geographically dispersed patient populations and a lack of standardized protocols- the study employs a multinational retrospective survey endorsed by the International Parkinson and Movement Disorder Society. This survey seeks to collect comprehensive data on clinical features, disease progression, age of onset, genetic variants, and concurrent neurological conditions, standardizing data collection across countries to provide a unified understanding of these conditions. Through retrospective review and molecular data analysis, the study aims to identify patterns and correlations between movement and seizure disorders, uncovering genotype-phenotype relationships. The initiative\'s goals are to enhance understanding of epilepsy-dyskinesia syndromes, inform precision medicine approaches, and foster international collaboration.
