Although dyskinesia is a frequent and important problem in Parkinson's disease (PD), a reliable assessment measure has not been thoroughly developed and tested. We modified the Obeso dyskinesia scale to create an objective rating scale for dyskinesia assessment during activities of daily living. Thirteen physicians and 15 study coordinators involved in a(More)
We studied families to clarify the mode of inheritance of idiopathic torsion dystonia among the Ashkenazim. Probands had symptoms before 28 years of age, had at least one Ashkenazi grandparent, and were ascertained independently of family history and not referred by another relative. All available first- and second-degree relatives were examined, and(More)
We used a rotation-sensitive movement monitor (RoMM) to quantify and characterize dyskinesia in Parkinson's disease (PD). Both upper limbs of 22 patients with dyskinetic PD were recorded and videotaped simultaneously. Three neurologists reviewed the video segments and rated severity of dyskinesia on a four-point scale; they also assessed any asymmetry of(More)
Idiopathic torsion dystonia (ITD) is a neurological disorder characterized by sustained muscle contractions that appear as twisting movements of the limbs, trunk, and/or neck, which can progress to abnormal postures. Most familial forms of ITD follow autosomal dominant transmission with reduced penetrance. The frequency of ITD in the Ashkenazi Jewish(More)
We reviewed the treatment outcomes of 81 patients with multifocal tic disorders followed in our movement disorders clinic. From the three drugs used, rank orders of effectiveness were haloperidol, clonazepam, and clonidine. Because of the risk of tardive dyskinesia, we suggest first a trial with clonazepam, later combined with clonidine if clonazepam alone(More)
The mechanism(s) of inheritance of primary dystonia are unclear. An autosomal recessive form among Ashkenazi Jews and an autosomal dominant form among non-Jews have been proposed. However, the patterns of inheritance, particularly among Ashkenazim, are controversial. In this report we have reviewed the literature particularly as it pertains to the mode of(More)
