- To evaluate the posterior subthalamic area (PSA) as a target for deep brain stimulation (DBS) in the treatment of essential tremor (ET). The ventral intermediate nucleus of the thalamus is the traditional target for DBS in the treatment of ET. Recent studies have presented beneficial effects of DBS in the PSA in the treatment of tremor. Twenty-one patients with ET were included in this study. All patients were evaluated before and 1 year after surgery, on and off stimulation, using the essential tremor rating scale (ETRS). A marked microlesional effect was noticed in 83%, in some cases obviating the need for electrical stimulation for many months. The total ETRS was reduced from 46.2 at baseline to 18.7 (60%). Item 5/6 (tremor of the upper extremity) was improved from 6.2 to 0.3 (95%), and items 11 to 14 (hand function) from 9.7 to 1.3 (87%) concerning the contralateral hand. Activities of daily living were improved by 66%. No severe complication occurred. Eight patients presented a postoperative mild dysphasia that regressed within days to weeks. DBS in the PSA resulted in a marked reduction of tremor.

- Background: There are no data available concerning whether patients with cervical dystonia who have recurrent or new symptoms after peripheral denervation surgery benefit similarly from pallidal deep brain stimulation compared with patients who receive primarily pallidal stimulation. Methods: Data on 7 cervical dystonia patients with recurrent or progressive dystonia after peripheral denervation who underwent pallidal stimulation were prospectively collected. Deep brain stimulation was performed in Mannheim/ Hannover, Germany, or in Umea, Sweden. To the subgroup from Mannheim/Hannover, a second group of patients without previous peripheral surgery was matched. Assessments included the Toronto Western Spasmodic Torticollis Rating Scale and the Burke-FahnMarsden dystonia rating scale, as well as the Tsui scale in the Swedish patients. Results: The 4 patients from Mannheim/Hannover experienced sustained improvement from pallidal stimulation by a mean of 57.5% according to the Toronto Western Spasmodic Torticollis Rating Scale (P <.05) and by a mean of 69.5% according to the Burke-FahnMarsden dystonia rating scale (P <.05) at long-term follow-up of 40.5 months. The patients from Umea had a mean Tsui score of 7 prior to surgery and a mean score of 3 at the mean follow-up of 8 months (62.5%). In the matched group the Toronto Western Spasmodic Torticollis Rating Scale improved by 58.8% and the Burke-Fahn-Marsden dystonia rating scale by 67% (P <.05) at long-term follow-up (mean, 41.5 months). Conclusions: Patients who had prior peripheral surgery for cervical dystonia experience improvement from subsequent pallidal stimulation that is comparable to that of de novo patients.

- Objectives: To determine whether alpha-synuclein dinucleotide repeat (REP1) genotypes are associated with survival in Parkinson's disease (PD). Methods: Investigators from the Genetic Epidemiology of Parkinson's Disease Consortium provided REP1 genotypes and baseline and follow-up clinical data for cases. The primary outcome was time to death. Cox proportional hazards regression models were used to assess the association of REP1 genotypes with survival. Results: Twenty-one sites contributed data for 6,154 cases. There was no significant association between alpha-synuclein REP1 genotypes and survival in PD. However, there was a significant association between REP1 genotypes and age at onset of PD (hazard ratio: 1.06; 95% confidence interval: 1.01-1.10; P value = 0.01). Conclusions: In our large consortium study, alpha-synuclein REP1 genotypes were not associated with survival in PD. Further studies of alpha-synuclein's role in disease progression and long-term outcomes are needed. (C) 2014 International Parkinson and Movement Disorder Society
