Introduction Subthalamic nucleus deep brain stimulation (STN-DBS) improves motor function in individuals with Parkinson disease (PD). The evidence about the effects of STN-DBS on the voice is still inconclusive. Objective To verify the effect of STN-DBS on the voice of Brazilian individuals with PD. Methods Sixteen participants were evaluated on the Unified Parkinson Disease Rating Scale—Part III, and by the measurement of the acoustic modifications in on and off conditions of stimulation. Results The motor symptoms showed significant improvement with STN-DBS on. Regarding the acoustic measures of the voice, only the maximum fundamental frequency (fhi) showed a statistical difference between on- and off-conditions, with reduction in off-condition. Conclusion Changes in computerized acoustic measures are more valuable when interpreted in conjunction with changes in other measures. The single finding in fhi suggests that DBS-STN increases vocal instability. The interpretation of this result should be done carefully, since it may not be of great value if other measures that also indicate instability are not significantly different.

Abstract BACKGROUND Subthalamic nucleus deep brain stimulation (STN DBS) is an effective adjunctive therapy for Parkinson disease. Studies have shown improvement of motor function but often exclude patients older than 75 yr. OBJECTIVE To determine the safety and effectiveness of STN DBS in patients 75 yr and older. METHODS A total of 104 patients (52 patients >75 yr old, 52 patients <75 yr old) with STN DBS were paired and retrospectively analyzed. The primary outcome was change in Unified Parkinson Disease Rating Scale (UPDRS) subscale III at 1 yr postoperatively, OFF medication. Secondary outcomes were changes in UPDRS I, II, and IV subscales and levodopa equivalents. Complications and all-cause mortality were assessed at 30 d and 1 yr. RESULTS Both cohorts had significant improvements in UPDRS III at 6 mo and 1 yr with no difference between cohorts. Change in UPDRS III was noninferior to the younger cohort. The cohorts had similar worsening in UPDRS I at 1 yr, no change in UPDRS II, similar improvement in UPDRS IV, and similar levodopa equivalent reduction. There were similar numbers of postoperative intracerebral hemorrhages (2/52 in each cohort, more severe in the older cohort) and surgical complications (4/52 in each cohort), and mortality in the older cohort was similar to an additional matched cohort not receiving DBS. CONCLUSION STN DBS provides substantial motor benefit and reduction in levodopa equivalents with a low rate of complications in older patients, which is also noninferior to the benefit in younger patients. STN DBS remains an effective therapy for those over 75 yr.

Object Parkinson disease (PD) is often accompanied by various postural abnormalities such as camptocormia (bent spine) or Pisa syndrome (lateral flexion). The authors studied the effect of subthalamic nucleus deep brain stimulation (STN DBS) on postural abnormality in patients with PD. Methods The authors retrospectively reviewed the clinical course of 18 patients who suffered from significant postural abnormality and underwent bilateral STN DBS. Patients whose preoperative posture score (Unified Parkinson's Disease Rating Scale III, item 28) was 2 or more in the “medication-on” state were enrolled in this study. Eight patients were considered to have camptocormia, and 10 patients were considered to have so-called Pisa syndrome. Nine patients showed apparent thoracolumbar spinal deformity on radiography. Most patients had significant motor fluctuations from levodopa. Results In 13 patients with moderate postural abnormality (score of 2 on item 28), 9 patients improved soon after surgery, but 1 patient relapsed. Two patients improved gradually over a long period after surgery, whereas 2 patients did not improve at all. In 5 patients with severe postural abnormality (score of 3 or 4 on item 28), 2 patients improved slightly in the long-term follow-up period after surgery, but 3 patients did not improve at all. Conclusions Postural abnormality in patients with PD could be ameliorated by STN DBS, and therefore surgery should be considered before irreversible spinal deformity develops.

Abstract BACKGROUND Pain is a well-recognized feature of Parkinson disease (PD), which is primarily a motor disorder. In a previous study, we showed that subthalamic deep brain stimulation (STN DBS) improves pain as well as motor symptoms 3 months after surgery in PD patients. OBJECTIVE To determine whether there is a long-term beneficial effect of STN DBS on pain in PD. METHODS We studied 21 patients with PD who underwent STN DBS. Motor symptoms were assessed using the Unified Parkinson's Disease Rating Scale and Hoehn and Yahr staging. Pain was evaluated by asking patients about the quality and severity of pain in each body part. Evaluations were performed at baseline and at 3 and 24 months after surgery. RESULTS At baseline, 18 of the 21 patients (86%) experienced pain. After surgery, most of the pain reported at baseline had improved or disappeared at 3 months and improved further at 24 months. The benefit of STN DBS for pain evaluated at 24 months was comparable to that with medication at baseline. At 24 months, 9 patients (43%) reported new pain that was not present at baseline. Most of the new pain was musculoskeletal in quality. Despite the development of new pain, the mean pain score at follow-up was lower than at baseline. CONCLUSION STN DBS improves pain in PD, and this beneficial effect persists, being observed after a prolonged follow-up of 24 months. In addition, in many of the PD patients new, mainly musculoskeletal pain developed on longer follow-up.

Abstract BACKGROUND Subthalamic nucleus (STN) deep brain stimulation is a successful intervention for medically refractory Parkinson disease, although its efficacy depends on optimal electrode placement. Even though the predominant effect is observed contralaterally, modest improvements in ipsilateral and midline symptoms are also observed. OBJECTIVE To elucidate the role of contact location of unilateral deep brain stimulation on contralateral, ipsilateral, and axial subscores of Parkinson disease motor symptoms. METHODS Eighty-six patients receiving first deep brain stimulation STN electrode placements were identified, yielding 73 patients with 3-month follow-up. Total preoperative and postoperative Unified Parkinson Disease Rating Scale Part III scores were obtained and divided into contralateral, ipsilateral, and midline subscores. Contact location was determined on immediate postoperative magnetic resonance imaging. A 3-dimensional ordinary “kriging” algorithm generated spatial interpolations for total, ipsilateral, contralateral, and midline symptom categories. Interpolative reconstructions were performed in the axial planes (z = −0.5, −1.0, −1.5, −3.5, −4.5, −6.0) and a sagittal plane (x = 12.0). Interpolation error and significance were quantified by use of a cross-validation technique and quantile-quantile analysis. RESULTS There was an overall reduction in Unified Parkinson Disease Rating Scale Part III symptoms: total = 37.0 ± 24.11% (P < .05), ipsilateral = 15.9 ± 51.8%, contralateral = 56.2 ± 26.8% (P < .05), and midline = 26.5 ± 34.7%. Kriging interpolation was performed and cross-validated with quantile-quantile analysis with high correlation (R2 > 0.92) and demonstrated regions of efficacy for each symptom category. Contralateral symptoms demonstrated broad regions of efficacy across the peri-STN area. The ipsilateral and midline regions of efficacy were constrained and located along the dorsal STN and caudal zona incerta. CONCLUSION We provide evidence for a unique functional topographic window in which contralateral, ipsilateral, and midline structures may achieve the best efficacy. Although there are overlapping regions, laterality demonstrates distinct topographies. Surgical optimization should target the intersection of optimal regions for these symptom categories.

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 < 0.001). The changes in Unified Parkinson's Disease Rating Scale motor subscores improved as follows: rest tremor, 74% (P < 0.001); rigidity, 58% (P < 0.001); bradykinesia, 37% (P < 0.001); pull test, 35% (P < 0.001); gait, 44% (P < 0.001); axial signs, 42% (P < 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.

OBJECTIVE The objective of this study was to evaluate clinical features and response to deep brain stimulation (DBS) in G2019S LRRK2-Parkinson disease (LRRK2-PD) and idiopathic PD (IPD). METHODS The authors conducted a clinic-based cohort study of PD patients recruited from the Mount Sinai Beth Israel Genetics database of PD studies. The cohort included 87 participants with LRRK2-PD (13 who underwent DBS) and 14 DBS participants with IPD enrolled between 2009 and 2017. The baseline clinical features, including motor ratings and levodopa-equivalent daily dose (LEDD), were compared among LRRK2-PD patients with and without DBS, between LRRK2-PD with DBS and IPD with DBS, and between LRRK2-PD with subthalamic nucleus (STN) and internal segment of the globus pallidus (GPi) DBS. Longitudinal motor scores (Unified Parkinson’s Disease Rating Scale–part III) and medication usage were also assessed pre- and postoperatively. RESULTS Compared to LRRK2-PD without DBS (n = 74), the LRRK2-PD with DBS cohort (n = 13) had a significantly younger age of onset, longer disease duration, were more likely to have dyskinesia, and were less likely to experience hand tremor at disease onset. LRRK2-PD participants were also more likely to be referred for surgery because of severe dyskinesia (11/13 [85%] vs 6/14 [43%], p = 0.04) and were less likely to be referred for medically refractory tremor (0/13 [0%] vs 6/14 [43%], p = 0.02) than were IPD patients. Among LRRK2-PD patients, both STN-DBS and GPi-DBS targets were effective, although the sample size was small for both groups. There were no revisions or adverse effects reported in the GPi-DBS group, while 2 of the LRRK2-PD participants who underwent STN-DBS required revisions and a third reported depression as a stimulation-related side effect. Medication reduction favored the STN group. CONCLUSIONS The LRRK2-PD cohort referred for DBS had a slightly different profile, including earlier age of onset and dyskinesia. Both the STN and GPi DBS targets were effective in symptom suppression. Patients with G2019S LRRK2 PD were well-suited for DBS therapy and had favorable motor outcomes regardless of the DBS target. LRRK2-DBS patients had longer disease durations and tended to have more dyskinesia. Dyskinesia commonly served as the trigger for DBS surgical candidacy. Medication-refractory tremor was not a common indication for surgery in the LRRK2 cohort.

Camptocormia, involuntary flexion of the spine, is aggravated by action and improves when supine, if there is no skeletal deformity. Camptocormia in Parkinson disease (PD) is frequently refractory to dopaminergic medication. Deep brain stimulation (DBS) has been used to treat camptocormia with variable results. We present a PD patient with no camptocormia in the supine position but with progressive thoracic trunk flexion to about 90 degrees as he stood up. He had profound gait impairment and freezing of gait (FOG) off medication, but gait and FOG improved on medication. Camptocormia improved to about 30 degrees, but he had severe dyskinesias. Because he had no skeletal deformity, improved on medication, and had dyskinesias, he had bilateral 130 Hz subthalamic (STN) DBS. His Unified Parkinson’s Disease Rating Scale (UPDRS) Part III improved from 37 to 13 (off medication/on DBS), and after 14 months his camptocormia had resolved. Camptocormia that is responsive to dopaminergic medication, without a skeletal deformity, may respond to bilateral high-frequency STN DBS.

Object The authors of this preliminary study investigated the outcome and feasibility of intraoperative microelectrode recording (MER) in patients with Parkinson disease (PD) undergoing deep brain stimulation of the subthalamic nucleus (STN) after anesthetic inhalation. Methods The authors conducted a retrospective analysis of 10 patients with PD who received a desflurane anesthetic during bilateral STN electrode implantation. The MERs were obtained as an intraoperative guide for final electrode implantation and the data were analyzed offline. The functional target coordinates of the electrodes were compared preoperatively with estimated target coordinates. Results Outcomes were evaluated using the Unified Parkinson's Disease Rating Scale 6 months after surgery. The mean improvement in total and motor Unified Parkinson's Disease Rating Scale scores was 54.27 ± 17.96% and 48.85 ± 16.97%, respectively. The mean STN neuronal firing rate was 29.7 ± 14.6 Hz. Typical neuronal firing patterns of the STN and substantia pars nigra reticulata were observed in each patient during surgery. Comparing the functional target coordinates, the z axis coordinates were noted to be significantly different between the pre- and postoperative coordinates. Conclusions The authors found that MER can be adequately performed while the patient receives a desflurane anesthetic, and the results can serve as a guide for STN electrode implantation. This may be a good alternative surgical method in patients with PD who are unable to tolerate deep brain stimulation surgery with local anesthesia.

Abstract BACKGROUND: Deep brain stimulation (DBS) has been associated with mood sequelae in a subset of patients operated on in either the subthalamic nucleus or the globus pallidus internus for the treatment of Parkinson disease. OBJECTIVE: To compare mood and motor outcomes in those with and without a presurgical history of depression. METHODS: Unilateral subthalamic nucleus or unilateral globus pallidus internus DBS patients followed up for a minimum of 6 months were included. All patients underwent a comprehensive outpatient psychiatric evaluation by a board-certified psychiatrist. Psychiatric diagnoses were based on Diagnostic and Statistical Manual, fourth edition, text revision, nomenclature (American Psychiatric Association, 2000). Motor and mood outcomes were compared. RESULTS: A total of 110 patients were included. There were no significant differences in baseline variables between the 2 groups. Those with a preoperative history of depression had significantly higher Beck Depression Inventory scores than the nondepression group after DBS (8.97 ± 7.55 vs 5.92 ± 5.71; P = .04). Patients with a depression history had less improvement (11.6%) in pre/post-DBS change when Unified Parkinson Disease Rating Scale motor scores were compared (P = .03) after adjustment for stimulation site and baseline demographic and clinical variables. Patients with a higher levodopa equivalent dose had a worse clinical motor outcome. CONCLUSION: Patients with a preoperative depression history had higher Beck Depression Inventory scores after DBS and significantly less (albeit small) improvement in pre/post-DBS change in Unified Parkinson Disease Rating Scale motor scores than patients without a history of depression.

ObjectiveTo study the effect of subthalamic nucleus (STN) deep brain stimulation (DBS) in patients with Parkinson disease (PD) and moderate to severe restless legs syndrome (RLS) on their RLS symptoms.MethodsPatients undergoing STN DBS surgery for PD completed the International RLS Study Group Rating Scale (IRLS) and RLS Quality of Life (QoL) questionnaires preoperatively and postoperatively at 6 months, 1 year, and 2 years. The primary outcome measure was IRLS sum score and subscales (severity and impact) and the secondary measure was RLS QoL scores. Differences among the mean scores over time were analyzed using mixed model regression.ResultsTwenty-two patients were enrolled. The preoperative IRLS sum scores were 19.59 ± 6.95, severity subscale 12.91 ± 4.33, impact subscale 4.45 ± 2.72, and transformed RLS QoL score 68.30 ± 20.26. The differences between preoperative and averaged postoperative scores were IRLS sum score −7.80, severity subscale −5.50, impact subscale −1.20, and RLS QoL 4.73. The overall F tests demonstrated differences among the times for the means of the IRLS sum and subscales: p < 0.05. There were no correlations between RLS symptoms improvement and PD motor symptoms improvement or reduction in PD medications. Half of the patients had at least 50% improvement and 27% had resolution of their RLS symptoms (IRLS = 0).ConclusionsSTN DBS significantly decreased RLS symptoms in patients with PD despite a decrease in dopaminergic treatment. This improvement was sustained over a 2-year period.Classification of evidenceThis study provides Class IV evidence that for patients with PD and moderate to severe RLS, STN DBS improves RLS symptoms.
