- Introduction: In a double-blind randomized crossover trial, we previously established that bilateral deep brain stimulation of the anteromedial globus pallidus internus (GPiam-DBS) is effective in significantly reducing tic severity in patients with refractory Tourette syndrome (TS). Here, we report the effects of bilateral GPiam-DBS on cognitive function in 11 of the 13 patients who had participated in our double-blind cross-over trial of GPi-DBS.Methods: Patients were assessed at baseline (4 weeks prior to surgery) and at the end of each of the three-month blinded periods, with stimulation either ON or OFF. The patients were evaluated on tests of memory (California Verbal Learning Test-II (CVLT-II); Corsi blocks; Short Recognition Memory for Faces), executive function (D-KEFS Stroop color-word interference, verbal fluency, Trail-making test, Hayling Sentence Completion test), and attention (Paced Auditory Serial Addition Test, Numbers and Letters Test).Results: GPiam-DBS did not produce any significant change in global cognition. Relative to pre-operative baseline assessment verbal episodic memory on the CVLT-II and set-shifting on the Trail-making Test were improved with DBS OFF. Performance on the cognitive tests were not different with DBS ON versus DBS OFF. GPiam-DBS did not alter aspects of cognition that are impaired in TS such as inhibition on the Stroop interference task or the Hayling Sentence Completion test.Conclusions: This study extends previous findings providing data showing that GPiam-DBS does not adversely affect cognitive domains such as memory, executive function, verbal fluency, attention, psychomotor speed, and information processing. These results indicate that GPiam-DBS does not produce any cognitive deficits in TS.

- Purpose: Deep brain stimulation (DBS) of the subthalamic nucleus (STN) has been the mainstream surgical procedure for advanced Parkinson’s disease (PD) during the last decade. Reports from a few individual centres have hinted that women who receive STN DBS are under-represented. We aimed to evaluate the gender distribution of patients with PD who had received STN DBS during the last ten years, and to discuss the findings in relation to studies on gender prevalence of PD.Methods: A search of the PubMed database of clinical papers in English language related to STN DBS between 2000 and 2009 was conducted. Care was taken to minimize redundancies in reporting of published patients. The proportion of men and women were expressed in total and according to pre-defined geographic regions.Results: One hundred and thirty five papers were eligible for review. The gender of the patients was specified in 119 papers on a total of 3880 patients, of which 63% were men. According to geographic origin of publications, the percentage of men with STN DBS was 68% in North America, 62% in Europe, 69% in Australia and 50% in Asia.Conclusions: The proportion of male patients who undergo STN DBS seems to exceed the reported male/female ratio of patients with PD.
