Service-based survey of dystonia in Munich

We performed a service-based epidemiological study of dystonia in
Munich, Germany. Due to favourable referral and treatment patterns
in the Munich area, we could provide confident data from dystonia
patients seeking botulinum toxin treatment. A total of 230 patients
were ascertained, of whom 188 had primary dystonia. Point
prevalence ratios were estimated to be 10.1 (95% confidence
interval 8.4-11.9) per 100,000 for focal and 0.3 (0.0-0.6) for
generalised primary dystonia. The most common focal primary
dystonias were cervical dystonia with 5.4 (4.2-6.7) and essential
blepharospasm with 3.1 (2.1-4.1) per 100,000 followed by laryngeal
dystonia (spasmodic dysphonia) with 1.0 (0.4-1.5) per 100,000.
