Abstract OBJECTIVE To assess the impact of different surgical targets and techniques, such as ablation and deep brain stimulation, to treat patients with L-dopa-induced dyskinesia (LID), a major therapeutic complication of Parkinson's disease. METHODS This review analyzes the effects of early surgical procedures to treat hyperkinesia and the current methods and targets used to combat LID in Parkinson's disease, which are mainly thalamotomy, pallidotomy, and deep brain stimulation of the globus pallidus internus and the subthalamic nucleus. RESULTS Available information indicates that surgery of the globus pallidus internus and thalamus (the pallidal receiving area) and of the subthalamic nucleus has a pronounced antidyskinetic effect. This effect is associated with a concomitant improvement in the parkinsonian (“off”-medication) state. Although it is more profound with pallidal and subthalamic surgery, such an effect can also be observed to some extent with thalamic surgery. The latter is attributable to the fact that surgery of the ventralis intermedius is primarily effective for treating tremor. An integral pallidothalamic pathway is needed for dyskinesia to be expressed. Thus, LID is less frequent after subthalamotomy or deep brain stimulation of the subthalamic nucleus through a functional effect mediated by the physiological normalization of the motor system and by an indirect effect associated with a reduction in the daily dose of L-dopa. CONCLUSION Surgery is the only treatment available for Parkinson's disease that can predictably improve both the parkinsonian motor syndrome and LID. The exact mechanisms involved in these effects are not well understood. Pallidal and thalamic surgery affecting pallidal relays reduce LID frequency by disrupting the pallidothalamic circuit, probably eliminating the neuronal activity associated with dyskinesia. Alternatively, the antidyskinetic effect of subthalamic nucleus surgery may in part be attributable to a reduction in the L-dopa dose as well as to the stabilization of the basal ganglia circuits after the surgical procedure.

Abstract BACKGROUND: Parkinson's patients, on average, gain weight after deep brain stimulation (DBS). OBJECTIVE: To determine potential differences in weight gain when comparing the subthalamic nucleus and the globus pallidus internus target. METHODS: A retrospective analysis was performed on the prospective, randomized cohort of National Institutes of Health COMPARE trial DBS patients who received unilateral subthalamic nucleus or globus pallidus internus DBS. Baseline weights were recorded before DBS surgery and at 6, 12, and 18 months postoperatively. Relationships between weight change and changes in Beck Depression Inventory score, Unified Parkinson's Disease Rating Scale (UPDRS) motor score (part III) (also the dyskinesia duration and disability subscores from UPDRS IV), and Hoehn-Yahr stage were determined via Spearman's rank-order correlation coefficients. Regression analyses were performed to investigate the effects of potential factors on weight change over time. RESULTS: Patients in the COMPARE DBS cohort gained a significant amount of weight, a mean of 4.86 lb (standard deviation = 8.73) (P = .001), but there was no significant difference between subthalamic nucleus and globus pallidus internus targets (weight gain of 4.29 ± 6.79 and 5.38 ± 10.32 lb, respectively; P = .68). Weight gain did not correlate with Beck Depression Inventory score change, UPDRS motor score, dyskinesia duration, dyskinesia disability change, or the Hoehn-Yahr stage (P = .62, .21, and .31, respectively). No specific variable was associated with weight gain, and there were no differences in binge eating post-surgery in either target. CONCLUSION: There were significant changes in weight over time after DBS therapy. However, neither Beck Depression Inventory score change nor UPDRS score change or dyskinesia was correlated with weight gain. No significant factor was associated with the weight change.

Object Difficulty with step initiation, called “start hesitation,” is related to gait bradykinesia and is an early hallmark of gait freezing in Parkinson disease (PD). Authors of this study investigated the effects of deep brain stimulation (DBS) and levodopa on step initiation before and 6 months after DBS surgery in 29 patients with PD who were randomized to either the bilateral subthalamic nucleus (STN) or globus pallidus internus (GPi) as the DBS site. Methods The authors measured the amplitude and duration of anticipatory postural adjustments (APAs), the feed-forward postural preparation that precedes the onset of voluntary step initiation, based on center-of-pressure displacements on a force plate. They also measured the length and velocity of the first step using a motion analysis system to study kinematics. Some of the patients (22) were from a large, multicenter, double-blind clinical trial, and all patients in the study (29, PD-DBS group) were randomized to DBS in either the bilateral STN (15 patients) or bilateral GPi (14 patients). Differences in step initiation were investigated in 2 conditions before surgery (off/on levodopa) and in 4 conditions after surgery (off/on levodopa combined with off/on DBS). Twenty-eight elderly healthy control volunteers (CTRL group) were also tested, and 9 control volunteers with PD who met the criteria for DBS (PD-C group) were tested at baseline and 6 months later. Results Patients in the PD-DBS group had smaller amplitudes and longer durations of APAs compared with those in the 28 healthy control volunteers in all conditions. Before surgery, APAs improved with levodopa. After surgery, the APAs were significantly worse than in the best-treatment state before surgery (DOPA condition), and responsiveness to levodopa decreased. No differences in APAs were detected between the STN and GPi groups. A comparison with PD control volunteers who did not undergo DBS surgery confirmed that a deterioration in step preparation was not related to disease progression. Step length and velocity were smaller in the PD-DBS group than in controls in all conditions. Before surgery, levodopa improved the length and velocity of the first step. Both step length and velocity were unchanged in the best-treatment state before surgery (DOPA condition) as compared with after surgery (DBS+DOPA), with only step velocity in the STN group getting worse after surgery. Conclusions Six months of DBS in the STN or GPi impaired anticipatory postural preparation for step initiation, the opposite effect as with levodopa. Deep brain stimulation disrupted postural preparation more than step execution, suggesting independent motor pathways for preparation and execution of gait. Although turning the stimulators on after surgery combined with levodopa benefited the postural preparation to step, a comparison of pre- and postsurgery conditions suggests that either the surgery itself or 6 months of continuous stimulation may lead to an alteration of circuits or plastic changes that impair step initiation.

Background: Deep Brain Stimulation (DBS) is regarded as a viable therapeutic choice for Parkinson’s Disease (PD). The two most common sites for DBS are the Subthalamic Nucleus (STN) and Globus Pallidus (GPi). In this study, the clinical effectiveness of these two targets was compared. Methods: A systematic literature search in electronic databases were restricted to English language publications 2010 to 2021. Specified MeSH terms were searched in all databases. Studies that evaluated the Unified Parkinson’s Disease Rating Scale (UPDRS) III were selected by meeting the following criteria: (1) had at least three months follow-up period; (2) compared both GPi and STN DBS; (3) at least five participants in each group; (4) conducted after 2010. Study quality assessment was performed using the Modified Jadad Scale. Results: 3577 potentially relevant articles were identified 3569 were excluded based on title and abstract, duplicate and unsuitable article removal. Eight articles satisfied the inclusion criteria and were scrutinized (458 PD patients). Majority of studies reported no statistically significant between-group difference for improvements in UPDRS III scores. Conclusions: Although there were some results in terms of action tremor, rigidity, and urinary symptoms, which indicated that STN DBS might be a better choice or regarding the adverse effects, GPi seemed better; but it cannot be concluded that one target is superior. Other larger randomized clinical trials with longer follow-up periods and control groups are needed to decide which target is more efficient for stimulation and imposes fewer adverse effects on the patients.
