Case Reports Multicenter StudyTremor in primary adult-onset dystonia: prevalence and associated clinical features.
To investigate the frequency and the main clinical features of tremor in primary adult-onset dystonia (PAOD). ⋯ Tremor is a relatively common feature occurring in about 17% of patients with primary late-onset dystonia. The association between tremor and dystonia spread suggests that this form of tremor may be a dystonic manifestation. Similarities in phenotypic features of DT and TAWD predominated over differences, suggesting that the two forms of tremor may be manifestations of the same disease. Differences in gender and body distribution of tremor between patients with dystonia and tremor and those of patients with essential tremor also suggest that tremor in dystonia and essential tremor are different entities.
