Abstract

Writer's cramp (WC) is a form of focal task‐specific dystonia, which is brought on by writing. Although most cases are sporadic, a positive family history is present in 5% to 20% of cases. To date, WC has been reported in several families with primary torsion dystonia, including DYT7, a pure focal dystonia, and in the mixed dystonias, DYT1, DYT6, and DYT13. We describe a family of Bulgarian descent with three brothers presenting with a very‐late‐onset dystonic WC, compatible with linkage to chromosome 18p. © 2005 Movement Disorder Society
