Parkinson’s disease (PD) is a neurodegenerative condition, which compromises the motor functions and causes the alteration of some executive brain functions. The presence of changes in cognitive symptoms in PD could be due to the procedure of deep brain stimulation (DBS). We searched in several databases for studies that compared performance in executive function tests before and after the DBS procedure in PE and then performed a meta-analysis. After the initial search, there were 15 articles that specifically evaluated the functions of verbal fluency, working memory, cognitive flexibility, abstract thinking, and inhibition. It was found that there were differences in the evaluation of the cognitive functions in terms of the protocols, which generated heterogeneity in the results of the meta-analysis. Likewise, a tendency to diminish functions like verbal fluency and inhibition was found, being this consistent with similar studies. In the other functions evaluated, no difference was found between pre- and postsurgery scores. Monitoring of this type of function is recommended after the procedure.

<p><strong>Introduction:</strong> Deep brain stimulation (DBS) is effective in advanced Parkinson’s disease (PD), improving motor symptoms, fluctuations and quality of life. However, adverse psychiatric outcomes have been reported, albeit variably and in an unstandardized fashion. We aimed to summarize the published evidence on the outcomes of anxiety and depressive symptoms in Parkinson’s disease patients following DBS, through systematic review and meta-analysis.<br /><strong>Material and Methods:</strong> PubMed was searched until May 2012 to identify studies assessing anxiety and depressive symptoms in PD patients who underwent bilateral DBS of the subthalamic nucleus (STN) or globus pallidus internus (GPi). Random effects metaanalyses were conducted for groups of at least three studies that were homogeneous regarding the design and the instruments used.<br /><strong>Results:</strong> 63 references were selected; 98.4% provided data on depression, and 38.1% on anxiety assessment scales. Two studies did not discriminate the target; from the remaining 61 references, short-term evaluation was performed in 37 (60.7%), mid-term in 36 (59.0%) and long-term in 5 (8.2%). Data on pre to postop variation was available in 57 (93.4%) reports and 16 (26.2%) presented STNDBS versus different comparison groups: GPi-DBS (n = 4 studies, 25.0%), eligible for surgery (n = 6, 37.5%), and medical treatment (n = 7, 43.8%).<br /><strong>Discussion:</strong> Improvement of depression and anxiety is apparent after DBS, more pronounced in the short-term, an effect that seems to wane in later assessments. Concerning depression, STN-DBS shows superiority against medical treatment, but not when compared to eligible for surgery control groups. The opposite is apparent for anxiety, as results favor medical treatment over STN-DBS, and STNDBS over eligible for surgery control group. Superiority of one target over the other is not evident from the results, but data slightly favors GPi for both outcomes.<br /><strong>Conclusion:</strong> The pattern and course of depressive symptoms and anxiety following DBS in PD is not clear, although both seem to improve in the short-term, especially depression following STN-DBS. Results are highly heterogeneous. Efforts should be carried out to standardize assessment procedures across centers.<br /><strong>Keywords:</strong> Parkinson’s Disease; Deep Brain Stimulation; Anxiety; Depression; Meta-Analysis.</p>

ObjectiveNo definitive comparative studies of the efficacy of ‘awake’ deep brain stimulation (DBS) for Parkinson’s disease (PD) under local or general anaesthesia exist, and there remains significant debate within the field regarding differences in outcomes between these two techniques.MethodsWe conducted a literature review and meta-analysis of all published DBS for PD studies (n=2563) on PubMed from January 2004 to November 2015. Inclusion criteria included patient number >15, report of precision and/or clinical outcomes data, and at least 6 months of follow-up. There were 145 studies, 16 of which were under general anaesthesia. Data were pooled using an inverse-variance weighted, random effects meta-analytic model for observational data.ResultsThere was no significant difference in mean target error between local and general anaesthesia, but there was a significantly less mean number of DBS lead passes with general anaesthesia (p=0.006). There were also significant decreases in DBS complications, with fewer intracerebral haemorrhages and infections with general anaesthesia (p<0.001). There were no significant differences in Unified Parkinson’s Disease Rating Scale (UPDRS) Section II scores off medication, UPDRS III scores off and on medication or levodopa equivalent doses between the two techniques. Awake DBS cohorts had a significantly greater decrease in treatment-related side effects as measured by the UPDRS IV off medication score (78.4% awake vs 59.7% asleep, p=0.022).ConclusionsOur meta-analysis demonstrates that while DBS under general anaesthesia may lead to lower complication rates overall, awake DBS may lead to less treatment-induced side effects. Nevertheless, there were no significant differences in clinical motor outcomes between the two techniques. Thus, DBS under general anaesthesia can be considered at experienced centres in patients who are not candidates for traditional awake DBS or prefer the asleep alternative.
