Randomized Controlled TrialSubthalamic nucleus deep brain stimulation in early stage Parkinson's disease.
Deep brain stimulation (DBS) is an effective and approved therapy for advanced Parkinson's disease (PD), and a recent study suggests efficacy in mid-stage disease. This manuscript reports the results of a pilot trial investigating preliminary safety and tolerability of DBS in early PD. ⋯ This study demonstrates that subjects with early stage PD will enroll in and complete trials testing invasive therapies and provides preliminary evidence that DBS is well tolerated in early PD. The results of this trial provide the data necessary to design a large, phase III, double-blind, multicenter trial investigating the safety and efficacy of DBS in early PD.

To evaluate the clinical characteristics, associated features, and treatment response of a large orthostatic tremor series seen over a 26-year period. ⋯ In our population of orthostatic tremor patients, mild postural hand tremor was a frequent finding. Over half of our patients had a family history of tremor, but a family history of orthostatic tremor was uncommon. Additional neurological features were seen in the minority of patients and we report possibly the first case of dementia with Lewy bodies associated with orthostatic tremor. Our series is the largest series of orthostatic tremor reported in the literature and contributes to understanding the clinical characteristics of this rare disease.
