A nationwide-data linkage study of idiopathic dystonia epidemiology in Wales


  • The prevalence of idiopathic dystonia was 1.2%, with incidence increasing over time as a result of improved clinical identification and understanding of genetic risk factors.  

Why this matters

  • Dystonia is a hyperkinetic movement disorder that results in repetitive movements and abnormal posture, subsequently affecting physical and social functioning.

  • Accurate epidemiological data is crucial to further understand this condition, for which the true prevalence remains largely unknown and varies widely between studies.
