Target localization for deep brain stimulation (DBS) is a challenging step that determines not only the correct placement of stimulation electrodes, but also influences the success of the DBS procedure as reflected in the desired clinical outcome of a patient. ⋯ LL-SSEPs represent a promising approach for DBS target localization in the STN, provided deeper understanding on their anesthesia effect is obtained. This approach is advantageous in that it does not require the patient's participation in an intraoperative setting.

Deep brain stimulation (DBS) is a well-established therapy for otherwise intractable movement disorders. Thus far, most patients receive nonrechargeable implantable pulse generators (IPG). Eventually, another intervention to replace the IPG is inevitable. ⋯ Our findings imply that IPG longevity is shorter in the Activa PC compared to the Kinetra. Higher TEED and more frequent IPG replacements might reduce IPG longevity.

DBS Electrodes With Single Disconnected Contacts: Long-Term Observation and Implications for the Management.
To evaluate the long-term course of quadripolar DBS electrodes with disconnected single contacts that cannot be used for DBS. ⋯ Disconnections of single contacts occur with increasing cumulative incidence during long-term DBS. Surgery is the main causative risk factor. In the majority of electrodes, the dysfunction remains restricted to the initial contact(s).

Deep brain stimulation (DBS) surgery for Parkinson's disease (PD) is usually performed as awake surgery allowing sufficient intraoperative testing. Recently, outcomes after asleep surgery have been assumed comparable. However, direct comparisons between awake and asleep surgery are scarce. ⋯ Overall motor function improved faster in the awake surgery group, but the difference ceased after one year. However, axial subitems were worse in the asleep surgery group suggesting that worsening of axial symptoms was risked improving overall motor function. Awake surgery still seems advantageous for STN-DBS in PD, although asleep surgery may be considered with lower threshold in patients not suitable for awake surgery.
