<b><i>Objective:</i></b> Asleep deep brain stimulation (DBS) for Parkinson’s disease (PD) is being performed more frequently; however, motor outcomes and safety of asleep DBS have never been assessed in a prospective randomized trial. <b><i>Methods:</i></b> We conducted a prospective, randomized, noncomparative trial to assess the motor outcomes of asleep DBS. Leads were implanted in the subthalamic nucleus (STN) according to probabilistic stereotactic coordinates with a surgical robot under O-arm<sup>©</sup> imaging guidance under either general anesthesia without microelectrode recordings (MER) (20 patients, asleep group) or local anesthesia with MER and clinical testing (9 patients, awake group). <b><i>Results:</i></b> The mean motor improvement rates on the Unified Parkinson’s Disease Rating Scale Part III (UPDRS-3) between OFF and ON stimulation without medication were 52.3% (95% CI: 45.4–59.2%) in the asleep group and 47.0% (95% CI: 23.8–70.2%) in the awake group, 6 months after surgery. Except for a subcutaneous hematoma, we did not observe any complications related to the surgery. Three patients (33%) in the awake group and 8 in the asleep group (40%) had at least one side effect potentially linked with neurostimulation. <b><i>Conclusions:</i></b> Owing to its randomized design, our study supports the hypothesis that motor outcomes after asleep STN-DBS in PD may be noninferior to the standard awake procedure.

Background. Treatment of freezing of gait (FOG) is always challenging because of its unpredictable nature and multifactorial physiopathology. Intestinal levodopa infusion has been proposed in recent years as a valuable option for its improvement. FOG in Parkinson’s disease (PD) can appear after deep brain stimulation in patients who never had gait symptoms. Objective. To study the effects of intestinal levodopa/carbidopa infusion in unresponsive-FOG that appears in PD patients treated with subthalamic nucleus deep brain stimulation. Methods. We retrospectively collected and analyzed demographic, clinical, and therapeutic data from five PD patients treated with subthalamic nucleus stimulation who developed unresponsive-FOG and received intestinal levodopa/carbidopa infusion as an alternative therapy. FOG was measured based on scores in item 14 of the Unified Parkinson’s Disease Rating Scale before and after intestinal levodopa infusion. Results. Administration of intestinal levodopa caused improvement of FOG in the “ON” state in four patients (80%) by 2 or more points in item 14 of the Unified Parkinson’s Disease Rating Scale. The improvement was maintained for at least 12 months. Conclusions. Intestinal levodopa infusion may be a valuable therapeutic option for unresponsive-FOG developed after subthalamic nucleus deep brain stimulation.

ObjectiveApathy has been reported as a possible adverse effect of deep brain stimulation of the subthalamic nucleus (STN-DBS). We investigated the prevalence and severity of apathy in 22 patients with Parkinson’s disease (PD) who underwent STN-DBS, as well as the effects of apathy on quality of life (QOL).MethodsAll patients were assessed with the Lille Apathy Rating Scale (LARS), the Apathy Scale (AS), and the Parkinson’s Disease Questionnaire and were compared to a control group of 38 patients on pharmacotherapy alone.ResultsThere were no significant differences in the prevalence or severity of apathy between patients who had undergone STN-DBS and those on pharmacotherapy alone. Significant correlations were observed between poorer QOL and degree of apathy, as measured by the LARS (p<0.001) and the AS (p=0.021). PD-related disability also correlated with both apathy ratings (p<0.001 and p=0.017, respectively).ConclusionOur findings suggest that STN-DBS is not necessarily associated with apathy in the PD population; however, more severe apathy appears to be associated with a higher level of disability due to PD and worse QOL, but no other clinico-demographic characteristics.

Abstract Objective: The aim of this study is to establish the safety and efficacy of bilateral subthalamic nucleus (STN) deep brain stimulation (DBS) in Parkinson's disease (PD) patients with disabling motor fluctuations performed with an expedient procedure with limited intraoperative mapping. Methods: Bilateral STN DBS systems were implanted in 110 PD patients. Targeting of STN was achieved with T2-weighted magnetic resonance imaging guidance and a stereotactic navigation system confirmed by limited electrophysiological mapping. The safety of the procedure was analyzed in all 110 patients. The efficacy of the procedure was assessed in the practically-defined off medication state in the 72 patients who underwent evaluations 3 to 12 months after electrode implantation. Results: Adverse effects were infrequent and transient with no incidence of death, hemiparesis, or seizure. In the 72 patients, STN DBS reduced total Unified Parkinson's Disease Rating Scale motor scores at the time of the follow-up evaluation by 47% from 43.4 ± 16.1 with stimulators off to 22.8 ± 11.6 with stimulators on (P &lt; 0.001). The changes in Unified Parkinson's Disease Rating Scale motor subscores improved as follows: rest tremor, 74% (P &lt; 0.001); rigidity, 58% (P &lt; 0.001); bradykinesia, 37% (P &lt; 0.001); pull test, 35% (P &lt; 0.001); gait, 44% (P &lt; 0.001); axial signs, 42% (P &lt; 0.001); and speech, 13% (P = 0.002). The prescribed total daily levodopa-equivalent dose decreased 45 ± 32%. We averaged 1.3 ± 0.9 electrodes passes per lead implantation. The mean operating time from the mounting of the stereotactic frame to its removal was 5 hours 42 minutes (median, 5 h 25 min; standard deviation, 1 h 12 min). Conclusion: This STN DBS surgical technique for PD is expedient with effective outcomes and low complication rates.

Abstract INTRODUCTION Deep brain stimulation (DBS) has traditionally been used to target the subthalamic nucleus (STN) or globus pallidus internus (GPi) to treat the bradykinesia and rigidity of Parkinson's disease (PD) and the ventral intermediate thalamic nucleus (VIM) to treat essential tremor (ET). Recent case reports have described targeting both the STN and VIM with a single trajectory to treat patients with tremor-dominant PD; yet, outcome data for this procedure remain sparse. METHODS We conducted a single-center retrospective review of all patients who underwent combined STN-VIM DBS. Demographic and outcome data, including Unified Parkinson Disease Rating Scale (UPDRS), changes in symptom severity, and levodopa equivalent daily dose (LEDD), were collected and analyzed. RESULTS Nineteen patients underwent combined STN-VIM trajectory DBS between January 2013 and April 2019. Patients were 90% male and 10% female, with an average age of 63.6 ± 12 yr. Average preoperative UPDRS was 24.2 and LEDD was 807.8. At an average follow-up of 23.9 mo, UPDRS and LEDD decreased by an average of 9.25 and 404.8, respectively. A total of 95% of our patients reported an improvement in tremor symptoms, and 58% were able to decrease the total medication burden. CONCLUSION Combined targeting of STN and VIM thalamus for tremor-dominant PD results in an excellent control of tremor symptoms, as well as a decrease in UPDRS and LEDD. Larger multicenter studies are necessary to validate this as the optimal DBS target for tremor-dominant PD.

AbstractThis study compares the effects on motor symptoms between conventional deep brain stimulation (cDBS) and closed-loop adaptive deep brain stimulation (aDBS) in patients with Parkinson’s Disease. The aDBS stimulation is controlled by the power in the beta band (12–35 Hz) of local field potentials recorded directly by subthalamic nucleus electrodes. Eight subjects were assessed in two 8-h stimulation sessions (first day, cDBS; second day, aDBS) with regular levodopa intake and during normal daily activities. The Unified Parkinson’s Disease Rating Scale (UPDRS) part III scores, the Rush scale for dyskinesias, and the total electrical energy delivered to the tissues per second (TEEDs) were significantly lower in the aDBS session (relative UPDRS mean, cDBS: 0.46 ± 0.05, aDBS: 0.33 ± 0.04, p = 0.015; UPDRS part III rigidity subset mean, cDBS: 2.9143 ± 0.6551 and aDBS: 2.1429 ± 0.5010, p = 0.034; UPDRS part III standard deviation cDBS: 2.95, aDBS: 2.68; p = 0.047; Rush scale, cDBS 2.79 ± 0.39 versus aDBS 1.57 ± 0.23, p = 0.037; cDBS TEEDs mean: 28.75 ± 3.36 µj s−1, aDBS TEEDs mean: 16.47 ± 3.33, p = 0.032 Wilcoxon’s sign rank test). This work further supports the safety and effectiveness of aDBS stimulation compared to cDBS in a daily session, both in terms of motor performance and TEED to the patient.

Objective: This study aimed to evaluate the direct anti-dyskinesia effect of deep brain stimulation (DBS) of subthalamic nucleus (STN) on levodopa-induced on-dyskinesia in Parkinson's disease (PD) patients during the early period after surgery without reducing the levodopa dosage.Methods: We retrospectively reviewed PD patients who underwent STN-DBS from January 2017 to October 2019 and enrolled patients with levodopa-induced on-dyskinesia before surgery and without a history of thalamotomy or pallidotomy. The Unified Dyskinesia Rating Scale (UDysRS) parts I+III+IV and the Unified Parkinson's Disease Rating Scale part III (UPDRS-III) were monitored prior to surgery, and at the 3-month follow-up, the location of active contacts was calculated by postoperative CT–MRI image fusion to identify stimulation sites with good anti-dyskinesia effect.Results: There were 41 patients enrolled. The postoperative levodopa equivalent daily dose (LEDD) (823.1 ± 201.5 mg/day) was not significantly changed from baseline (844.6 ± 266.1 mg/day, P = 0.348), while the UDysRS on-dyskinesia subscores significantly decreased from 24 (10–58) to 0 (0–18) [median (range)] after STN stimulation (P &lt; 0.0001). The levodopa-induced on-dyskinesia recurred in stimulation-off/medication-on state in all the 41 patients and disappeared in 39 patients when DBS stimulation was switched on at 3 months of follow-up. The active contacts which correspond to good effect for dyskinesia were located above the STN, and the mean coordinate was 13.05 ± 1.24 mm lateral, −0.13 ± 1.16 mm posterior, and 0.72 ± 0.78 mm superior to the midcommissural point.Conclusions: High-frequency electrical stimulation of the area above the STN can directly suppress levodopa-induced on-dyskinesia.

Abstract Background To study the effects of subthalamic nucleus deep brain stimulation (STN-DBS) on autonomic dysfunction in Parkinson's disease (PD) patients. Methods 57 PD patients, who underwent bilateral STN-DBS from March to December 2018, were retrospectively analyzed, preplanned assessments at baseline and postoperatively at 1, 3 and 6 months also included the Scales for Outcomes in Parkinson's Disease-Autonomic questionnaire (SCOPA-Aut), the Unified Parkinson's Disease Rating Scale (UPDRS) III score, levodopa equivalent day dose (LEDD), Parkinson's Disease Quality of Life Scale (PDQ-39), the Hamilton Anxiety Rating Scale (HAMA), the Hamilton Depression Rating Scale (HAMD). Results The SCOPA-Aut scores improved significantly [14.59% (18.32%), 24.00% (27.05%), 22.16% (27.07%), respectively, all P <0.001] at 1 months, 3 months, 6months of STN-DBS respectively. Analysis of the SCOPA-Aut subitems showed significant improvement only in urine and thermoregulation subitems at 6 months after operation (P <0.001). There was no significant correlation between the improvement rate of SCOPA-Aut scores and the improvement rate of PDQ-39 scores (P>0.05) at 6 months after operation. SCOPA-Aut scores was positively correlated with age (r=0.428, P=0.001); The improvement rate of SCCOPA-Aut scores was positively correlated with the improvement rate of HAMA and HAMD scores (HAMA: r=0.325, P=0.015; HAMD: r=0.265, P=0.049) at 6 months after operation. Conclusion STN-DBS can improve autonomic dysfunction symptoms of PD patients, urinary and thermoregulatory subitems of autonomic dysfunction were improved in the short term after operation. There was a close relationship between improved autonomic symptoms and improved anxiety and depression 6 months after operation. We should pay more attention to the autonomic dysfunction in Parkinson's disease, detailed preoperative evaluation and postoperative follow-up, so as to better improve the QOL of patients.
