Abstract

In Iceland, the crude prevalence for all types of primary dystonia was 37.1/10⁵ (confidence interval, 30.4-44.9). Focal dystonia had the highest prevalence (31.2/10⁵), followed by segmental (3.1/10⁵), multifocal (2.4/10⁵) and generalized dystonia (0.3/10⁵). Cervical dystonia was the most common focal dystonia (11.5/10⁵), followed by limb dystonia (8.0/10⁵), laryngeal dystonia (5.9/10⁵), blepharospasm (3.1/10⁵), and oromandibular dystonia (2.8/10⁵). The male:female ratio for all patients was 1:1.9 (P = 0.0007), and females outnumbered males in all subtypes except oromandibular dystonia. Mean age of onset for all patients was 42.7 years (range, 3-82 years). This prevalence of primary dystonia is higher than in most reported studies, possibly because of more complete ascertainment but the relative frequencies of dystonia subtypes is similar.
