BACKGROUND:: Focal hand dystonia may be task specific, as is the case with writerʼs cramp. In early stages, task specificity can be so specific that it may be mistaken for a psychogenic movement disorder. METHODS:: We describe 4 patients who showed extreme task specificity in writerʼs cramp. They initially only had problems writing either a single letter or number. Although they were largely thought to be psychogenic, they progressed to typical writerʼs cramp. CONCLUSIONS:: Early recognition of this condition may provide an opportunity for early initiation of treatment. © 2011 Movement Disorder Society
