Due to clinical heterogeneity, variable age at presentation, and overlapping features with other disorders, dystonia is under-recognized. The presence of dystonic tremor is often a reason for misdiagnosis. We report an illustrative case of a patient with DYT1 dystonia who was originally misdiagnosed with Parkinson disease. Careful physical examination and history-taking can reveal dystonia and prompt appropriate diagnostic studies, which, in turn, can lead to potentially life-changing treatment. Our report illustrates typical challenges in the recognition and diagnosis of dystonia, and serves to increase clinicians' awareness of this disabling, but treatable, condition.
