title: Frequency and significance of vocalizations in Sydenham's chorea.
abstract: Sydenham's chorea (SC) is a complication of Streptococcus infection characterized by a combination of motor and non-motor features. We have investigated the presence of vocalizations in 89 consecutive patients with SC evaluated during a one-year period in the UFMG Movement Disorders Clinic. Seven (4/3 M/F) of the 89 patients (29/60 M/F) presented with simple vocalizations not preceded by premonitory sensations but in association with facial chorea in five patients. These findings suggest that vocalizations are not a common feature in SC and their phenomenology is quite distinct from the characteristics of vocal tics in tic disorders.
