Object The authors analyze long-term outcome in a substantial number of patients who underwent subthalamic nucleus (STN) deep brain stimulation (DBS) surgery under general anesthesia. Methods Eighty-two patients underwent bilateral placement of DBS electrodes under general anesthesia for advanced Parkinson disease; the STN was the target in all cases. All patients underwent intraoperative microelectrode recording of the STN. No intraoperative macrostimulation was performed. Unified Parkinson's Disease Rating Scale (UPDRS) data were recorded in 28 patients. Assessment of outcome was performed using the UPDRS (in 28 cases), the electrophysiological recordings (in all 82 cases), medication reduction (in 78 cases), and complications (in 82 cases). Results There was improvement in UPDRS scores across all measures following surgery. The total UPDRS score, off medication, improved from 68.78 (geometrical mean, 95% CI 61.76–76.60) preoperatively to 45.89 (geometrical mean, 95% CI 34.86–60.41) at 1 year postoperatively (p = 0.003, data available in 26 patients). Improvements were obtained in UPDRS Part II (Activities of Daily Living) off medication (p = 0.001) and also UPDRS Part III (Motor Examination) off medication (p < 0.001). Results for the on-medication and on-stimulation states also showed a statistically significant improvement for UPDRS Part III (p = 0.047). Good microelectrode recording of the STN was obtained under general anesthesia; the median first-track length was 4.0 mm, and the median number of tracks passed per patient was 3.0. The median reduction in levodopa medication was 58.1% (interquartile range 42.9%–73.3%). One patient had an intracerebral hemorrhage in the track of 1 electrode but did not require surgical evacuation. One patient had generalized convulsive seizures 24 hours postoperatively and was intubated for seizure control. Unified Parkinson's Disease Rating Scale scores were obtained in 26 patients at 1 year, 28 patients at 3 years, 17 at 5 years, and 7 at 7 years postoperatively. Up to 7 years postoperatively, there was sustained improvement in the total UPDRS score. The results in these patients showed minimal deterioration in the motor section of the UPDRS over time, up to 7 years following the operation. The authors found no evidence that the UPDRS Part II scores changed significantly over the period of 1–7 years after surgery (p = 0.671, comparison of mean scores at 1 and 7 years using generalized estimating equations). Conclusions Long-term outcomes confirm that it is both safe and effective to perform STN DBS under general anesthesia. As part of patient choice, this option should be offered to all DBS candidates with advanced Parkinson disease to enable more of these patients to undergo this beneficial surgery.

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 &gt;75 yr old, 52 patients &lt;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.

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 &lt; .05), ipsilateral = 15.9 ± 51.8%, contralateral = 56.2 ± 26.8% (P &lt; .05), and midline = 26.5 ± 34.7%. Kriging interpolation was performed and cross-validated with quantile-quantile analysis with high correlation (R2 &gt; 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.

Background & Objective:  Parkinson’s disease (PD) is the second most common Neurodegenerative disorder after Alzheimer’s disease. There are several surgical procedures for advanced PD, but amongst all deep brain stimulation has proven to be safest and effective. The objective of this study was to see the outcome of DBS for the treatment of PD in terms of improvement in MDS UPDRS over 5 years. Material and Methods:  44 patients were included in study from Oct 2014 to Sep 2019. History, examination was carried out, and preoperative MDS-UPDRS (Movement Disorder Society Unified Parkinson’s Disease Rating Scale) was recorded. Postoperative improvement in MDS-UPDRS score was assessed at first Programming, 2nd week, and 6th week and at 3rd month. Results:  At baseline the mean, the MDS – UPDRS (Part-I) score was 14.20 ± 0.61 and at the end of 3rd month, the mean score was 11.18 ± 0.47 respectively. At baseline the mean, the MDS – UPDRS (part-II) score was 18.99 ± 0.70 and at the end of 3rd month, the mean score was 13.01 ± 0.57, respectively. At baseline the mean, the MDS – UPDRS (part-III) score was 45.19 ± 0.90 and at the end of 3rd month, the mean score was 25.15 ± 1.20 respectively. At baseline the mean, the MDS – UPDRS (part-IV) score was 10.18 ± 0.87 and at the end of 3rd month, the mean score was 3.85 ± 1.03, respectively.  Conclusion:  The Deep Brain Stimulation (DBS) is safe and effective in the management of PD.

Objective:To report on the long-term outcomes of deep brain stimulation (DBS) of the thalamic ventral intermediate nucleus (VIM) in Parkinson disease (PD), essential tremor (ET), and dystonic tremor.Methods:One hundred fifty-nine patients with PD, ET, and dystonia underwent VIM DBS due to refractory tremor at the Grenoble University Hospital. The primary outcome was a change in the tremor scores at 1 year after surgery and at the latest follow-up (21 years). Secondary outcomes included the relationship between tremor score reduction over time and the active contact position. Tremor scores (Unified Parkinson's Disease Rating Scale-III, items 20 and 21; Fahn, Tolosa, Marin Tremor Rating Scale) and the coordinates of the active contacts were recorded.Results:Ninety-eight patients were included. Patients with PD and ET had sustained improvement in tremor with VIM stimulation (mean improvement, 70% and 66% at 1 year; 63% and 48% beyond 10 years, respectively; p < 0.05). There was no significant loss of stimulation benefit over time (p > 0.05). Patients with dystonia exhibited a moderate response at 1-year follow-up (41% tremor improvement, p = 0.027), which was not sustained after 5 years (30% improvement, p = 0.109). The more dorsal active contacts' coordinates in the right lead were related to a better outcome 1 year after surgery (p = 0.029). During the whole follow-up, forty-eight patients (49%) experienced minor side effects, whereas 2 (2.0%) had serious events (brain hemorrhage and infection).Conclusions:VIM DBS is an effective long-term (beyond 10 years) treatment for tremor in PD and ET. Effects on dystonic tremor were modest and transient.Classification of evidence:This provides Class IV evidence. It is an observational study.

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.

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.
