Predictors of second-sided deep brain stimulation for Parkinson's disease.

CONCLUSIONS: Younger patients, those undergoing GPi-targeted unilateral DBS, and patients who responded better to the initial DBS were more likely to undergo early second-sided lead placement. Therefore, these patients, and patients who are more responsive to medication preoperatively (as a proxy for DBS responsiveness), may benefit from consideration of initial bilateral DBS.

n J Abstract In Germany various concepts for treating patients with Parkinson's disease (PD) are available, e.g. oral medication with levodopa or deep brain stimulation (DBS), depending on the stage and severity of symptoms and also multidisciplinary management up to intersectoral treatment approaches (e.g. complex PD treatment and integrative care concepts). Nevertheless, in the treatment of patients with PD a comprehensive provision of services and a nationwide standardized collation of treatment quality are so far lacking. This is particularly true for technically complicated procedures, which necessitate ...

AbstractThere is evidence to suggest that some patients who undergo Deep Brain Stimulation can experience changes to dispositional, emotional and behavioural states that play a central role in conceptions of personality, identity, autonomy, authenticity, agency and/or self (PIAAAS). For example, some patients undergoing DBS for Parkinson ’s Disease have developed hypersexuality, and some have reported increased apathy. Moreover, experimental psychiatric applications of DBS may intentionally seek to elicit changes to the patient’s dispositional, emotional and behavioural states, in so far as dysfunctions in thes...

This study aimed to evaluate the changes of laterality after deep brain stimulation (DBS) and the association between dopamine transporter SPECT using 123I FP-CIT (DAT SPECT) and symptom laterality in PD before and after DBS. Methods Nineteen patients with PD who received bilateral subthalamic nucleus DBS were enrolled. The clinical scores including Unified Parkinson Disease Rating Scale (UPDRS) and Hoehn and Yahr were evaluated at baseline, 6 months, and 1 year after DBS. Also, the patients underwent DAT SPECT before and 6 months and 1 year after DBS. Symptom and DAT laterality indices were determined based on the UPDR...

Conclusions: The FC of ECN in PD patients was different from that in normal controls, but the FC of the ECN in patients with PD may not be altered by DBS. This suggests that the ECN may be considered an imaging biomarker for the identification of PD but may not be a good imaging biomarker for the evaluation of DBS efficacy. PMID: 32148755 [PubMed]

ConclusionsIn this multicenter study with a 24  months follow-up, we report significant sustained improvements after bilateral STN-DBS using a PD-specific sleep scale and a significant relationship between sleep and QoL improvements. This highlights the importance of sleep in holistic assessments of DBS outcomes.

AbstractSeveral single-center studies and one large multicenter clinical trial demonstrated that directional deep brain stimulation (DBS) could optimize the volume of tissue activated (VTA) based on the individual placement of the lead in relation to the target. The ability to generate axially asymmetric fields of stimulation translates into a broader therapeutic window (TW) compared to conventional DBS. However, changing the shape and surface of stimulating electrodes (directional segmented vs. conventional ring-shaped) also demands a revision of the programming strategies employed for DBS programming. Model-based approac...

CONCLUSIONS: iMRI-guided GPi-DBS lead placement in PD patients was associated with significant improvement in clinical outcomes, comparable to those observed following MER-guided DBS lead placement. Furthermore, iMRI-guided DBS implantation produced a similar safety profile to that of the MER-guided procedure. As such, iMRI guidance is an alternative to MER guidance for patients undergoing GPi-DBS implantation for PD. PMID: 32114534 [PubMed - as supplied by publisher]

Chronic pain is an enigma for both pain doctors and their patients: difficult to understand (as everyone’s pain is different), challenging to treat effectively, and frustrating to live with. Desperate patients sometimes turn to drastic and irreversible surgical procedures, like amputating nerves to relieve pain, and unfortunately even those procedures may fail to provide the hoped-for results. Fortunately there have been great strides in research related to pain perception and our nervous system’s reaction to various pain treatments, and we’ve been able to develop novel devices that provide many people wi...
