The accuracy of electrode placement in the subthalamic nucleus (STN) is critical for the procedure's success. The long-standing debate between electrophysiological recording (MER) and imaging-based targeting remains at the forefront of neurosurgical discussions. MER has traditionally been used to enhance the precision of DBS targeting, indicated by changes in local field potentials (LFPs), which correlate with Parkinsonian motor symptoms such as rigidity, bradykinesia, and tremor. However, the necessity of MER has been questioned due to advances in imaging techniques and the potential risks associated with the practice, including hemorrhage and cognitive decline post-surgery. A critical appraisal of the literature reveals mixed opinions, with recent meta-analyses showing no significant increase in hemorrhage risks with MER but demonstrating a modest increase in adverse cognitive outcomes using multiple electrodes. Despite improved imaging modalities enabling more accurate radiological targeting, MER remains a favored technique among surgeons for its direct feedback on electrode placement. Additionally, the aspect of conducting surgery under awake conditions versus general anesthesia is reviewed, considering the anxiety and discomfort associated with awake surgery against the limitations of performing electrophysiological recordings under general anesthesia. The current consensus underscores the importance of accurate electrode placement, achievable through a combination of MER, test stimulation, and intraoperative imaging, while also acknowledging the growing confidence in image-guided procedures performed under general anesthesia. This review highlights the need for individualized approaches considering patient-specific risks and the evolving landscape of DBS surgery.</p></div>","PeriodicalId":100359,"journal":{"name":"Deep Brain Stimulation","volume":"4 ","pages":"Pages 32-35"},"PeriodicalIF":0.0,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949669123000192/pdfft?md5=8874f198e3472734cd54f0bcc0898f40&pid=1-s2.0-S2949669123000192-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139019117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite its efficacy, complications, particularly infections, are a concern. This article reviews the prevalence, risk factors, pathogens, infection locations, timing, surgical approaches, prevention strategies, and treatment methods associated with infections following DBS procedures. DBS surgeries have gained popularity due to their adjustability, but infections pose challenges. Surgical site infections (SSIs) are common (0% to 24% cases) and extensively studied regarding patient groups, locations, timing, and pathogens. Expanding patient groups, including conditions like Tourette syndrome and epilepsy, have varying infection risks. Infections occur at burr-hole, extension, and implantable pulse generator (IPG) sites. Staphylococcus aureus is a primary pathogen, yet bacterial DNA on IPGs and colonization complicate understanding. Surgical approaches, staged or non-staged, show comparable infection rates. The influence of repetitive pulse generator replacements on infection rates is debated. Lead externalization, topical vancomycin powder, and other factors impact infection risk. Treating DBS-related infections often requires hardware extraction and antibiotic treatment. Innovations like ethylene oxide sterilization and hydrogen peroxide show potential. Algorithms suggest partial explantation for localized infections. Cost analyses favor starting with antibiotics. Infections persist despite progress; understanding risks, pathogens, and strategies is vital for optimal outcomes in DBS.</p></div>","PeriodicalId":100359,"journal":{"name":"Deep Brain Stimulation","volume":"3 ","pages":"Pages 16-18"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949669123000131/pdfft?md5=ed1c273bbc94b70e3ac2092dbe57b881&pid=1-s2.0-S2949669123000131-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138480409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dorsal anterior cingulate cortex (dACC) plays an important role in cognitive control and is therefore hypothesized to contribute to the pathogenesis of OCD. In this review, we aim to gain a wider understanding of the specific functions of the dACC and its role in the pathophysiology of OCD. The dACC is part of the cortico-basal ganglia-thalamo-cortical loop, where it forms connections between sensory input streams, cognitive and affective processing regions, and structures that regulate behaviour. This position facilitates a broad function for the dACC in multiple domains, which center on goal-directed behaviour and reward-based learning. When presented with a certain threatening stimulus, the dACC instructs downstream structures to select actions to respond to this particular stimulus, based on previous experiences We hypothesize that hyperactivity of the dACC may impair goal-directed behaviour in OCD patients which in turn may lead to obsessive-compulsive symptoms by creating an over-reliance on threatening stimuli and inadequate selection of neutralizing actions. The working mechanisms of cognitive behavioural therapy, serotonergic medication, repetitive transcranial magnetic stimulation and deep brain stimulation in OCD may be in part explained by the normalization of the activity of the dACC within the cortico-basal ganglia-thalamo-cortical (CBGTC) loop.</p></div>","PeriodicalId":100359,"journal":{"name":"Deep Brain Stimulation","volume":"3 ","pages":"Pages 1-7"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49759526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
