Clin Neurol Neurosurg 2024; 242:108319. [PMID: 38723583 DOI: 10.1016/j.clineuro.2024.108319] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Revised: 04/30/2024] [Accepted: 05/04/2024] [Indexed: 06/16/2024]
Abstract
INTRODUCTION The decision to offer deep brain stimulation (DBS) to elderly patients with Parkinson's disease (PD) presents challenges due to higher perceived risks and uncertain long-term benefits. Here, we aimed to compare the outcomes after DBS for elderly versus non-elderly patients with PD. METHODS We analyzed data from our institutional cohort and retrieved publicly available data through a systematic review. The exposure was age at DBS electrode insertion, which was defined as elderly (≥70 years old) and non-elderly (<70 years old). The outcomes examined were changes in the Movement Disorders Society-Parkinson's Disease Rating Scale (MDS-UPDRS) or UPDRS part III total score, levodopa-equivalent daily dose (LEDD), and adverse events. RESULTS The included studies and our cohort comprised a total of 527 patients, with 111 (21.1 %) classified as elderly. There was no statistically significant difference in the change in MDS-UPDRS or UPDRS part III total score and generally no statistically significant difference in the change in LEDD between the elderly and non-elderly patients. Elderly patients had a higher incidence of wound infection (elderly 5.4 % vs non-elderly 1.9 %; p = 0.087) and inadequate wound healing (elderly 3.6 % vs non-elderly 1.4 %; p = 0.230), but this difference was not statistically significant. There was no significant difference in the incidence of mortality (elderly 0 % vs non-elderly 0 %; p = 1.000), stroke (elderly 0 % vs non-elderly 0.2 %; p = 1.000), and cognitive decline between the age groups. CONCLUSIONS Notwithstanding the trend towards a higher risk of wound infection and inadequate wound healing, elderly patients have similar motor outcomes and levels of PD medication reduction as non-elderly patients after DBS for PD. Hence, age should not be used as the sole criterion for determining eligibility for DBS, and the decision to offer DBS to elderly patients should be personalized and made in a multidisciplinary setting, taking into consideration patient- and disease-related factors.

Abstract
Deep Brain Stimulation (DBS) is an effective treatment option for patients with dopaminergic complications of Parkinson's disease (PD) and drug-refractory PD tremor. However, DBS and its indications can be challenging, and they are not often debated in the medical community. Through a critical narrative review, the objective of this paper is to improve the comprehension of DBS indications and help to solve the puzzle that this process can be. Proper patient selection is the first step for a good surgical outcome. In this review, then, relevant considerations are discussed, involving PD genes, PD phenotypes, indications of early stages, non-motor symptoms, neuroimaging predictors, comorbidities, and age. Individualized approaches are encouraged, including clinical and radiological factors. Social support during the whole follow-up and expectations alignment are necessary through this process and are also debated.

Abstract
Multiple Sclerosis (MS) management in individuals aged 55 and above presents unique challenges due to the complex interaction between aging, comorbidities, immunosenescence, and MS pathophysiology. This comprehensive review explores the evolving landscape of MS in older adults, including the increased incidence and prevalence of MS in this age group, the shift in disease phenotypes from relapsing-remitting to progressive forms, and the presence of multimorbidity and polypharmacy. We aim to provide an updated review of the available evidence of disease-modifying treatments (DMTs) in older patients, including the efficacy and safety of existing therapies, emerging treatments such as Bruton tyrosine kinase (BTKs) inhibitors and those targeting remyelination and neuroprotection, and the critical decisions surrounding the initiation, de-escalation, and discontinuation of DMTs. Non-pharmacologic approaches, including physical therapy, neuromodulation therapies, cognitive rehabilitation, and psychotherapy, are also examined for their role in holistic care. The importance of MS Care Units and advance care planning are explored as a cornerstone in providing patient-centric care, ensuring alignment with patient preferences in the disease trajectory. Finally, the review emphasizes the need for personalized management and continuous monitoring of MS patients, alongside advocating for inclusive study designs in clinical research to improve the management of this growing patient demographic.

Abstract
BACKGROUND Deep brain stimulation (DBS) has been proven to be a safe, reversible, cost-effective procedure for treatment of Parkinson's disease. Final electrode position remains a significant factor determining the outcomes of subthalamic nucleus DBS (STN-DBS). This study aims to analyze the final lead position in three-dimensional plane and its effect on gross and fine motor outcomes in cases of advanced Parkinson's disease operated for STN-DBS. METHODS Patients who underwent bilateral STN-DBS were prospectively followed for improvement in gross motor outcomes at 6 months. Improvement in dysgraphia was analyzed by Fahn-Tolosa-Marin Tremor Rating Scale Part B Score. Postoperative outcomes were correlated with final electrode position. RESULTS A total of 64 Patients (128 leads) were analyzed. Patients who were less than 65 years of age at time of surgery had more significant reduction in UPDRS III (P=0.02). Cases with deviation of left x less than 3 mm had significant reduction in UPDRS III (P=0.05) and speech sub-scores (P=0.05). Deviation less than 2 mm in left x was associated with reduction in gait sub-scores (P=0.04). Optimal placement of right y electrode was associated with reduction in UPDRS III (P=0.02). Significant reduction in Fahn-Tolosa-Marin Tremor Rating Scale Part B Score was noted after DBS (P=0.001). CONCLUSIONS Subthalamic nucleus DBS thus results in significantly improved functional outcome particularly in patients with age less than 65 years. Accurate final electrode position is associated with maximum clinical benefit and improvement in dysgraphia.

Abstract
Deep brain stimulation (DBS) is a surgical procedure that uses electrical neuromodulation to target specific regions of the brain, showing potential in the treatment of neurodegenerative disorders such as Parkinson's disease (PD) and Alzheimer's disease (AD). Despite similarities in disease pathology, DBS is currently only approved for use in PD patients, with limited literature on its effectiveness in AD. While DBS has shown promise in ameliorating brain circuits in PD, further research is needed to determine the optimal parameters for DBS and address any potential side effects. This review emphasizes the need for foundational and clinical research on DBS in different brain regions to treat AD and recommends the development of a classification system for adverse effects. Furthermore, this review suggests the use of either a low-frequency system (LFS) or high-frequency system (HFS) depending on the specific symptoms of the patient for both PD and AD.

Abstract
Data on the use of device-aided therapies (DATs) in people with Parkinson's disease (PwP) are scarce. Analyzing data from the Care4PD patient survey, we (1) evaluated application frequency and type of DAT in a larger, nationwide, cross-sectoral PwP sample in Germany; (2) analyzed the frequency of symptoms indicative for advanced PD (aPD) and need for DAT amongst the remaining patients and (3) compared the most bothersome symptoms and need for professional long-term care (LTC) of patients with and without suspected aPD. Data from 1269 PwP were analyzed. In total, 153 PwP (12%) received DAT, mainly deep brain stimulation (DBS). Of the remaining 1116 PwP without DAT, >50% fulfilled at least one aPD criterion. Akinesia/rigidity and autonomic problems were most bothersome for PwP with and without suspected aPD, with more tremor in the non-aPD and more motor fluctuations and falls in the aPD group. To recapitulate, the German DAT application rate is rather low, although a large proportion of PwP fulfills aPD criteria indicating a need for intensified treatment strategies. Many reported bothersome symptoms could be overcome with DAT with benefits even for LTC patients. Thus, precise and early identification of aPD symptoms (and therapy-resistant tremor) should be implemented in future DAT preselection tools and educational trainings.

Abstract
OBJECTIVE Degeneration of dopaminergic neurons in the substantia nigra projecting to the striatum is responsible for the motor symptoms in Parkinson's disease (PD). Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is a well-established procedure to alleviate these symptoms in advanced PD. Yet the mechanism of action, especially the effects of STN-DBS on the availability of striatal dopamine transporter (DAT) as a marker of nigrostriatal nerve cell function, remains largely unknown. The aim of this study was therefore to evaluate whether 1) DAT availability changes within 1 year of STN-DBS and 2) the clinical outcome can be predicted based on preoperative DAT availability. METHODS Twenty-seven PD patients (mean age 62.7 ± 8.9 years; mean duration of illness 13.0 ± 4.9 years; PD subtypes: akinetic-rigid, n = 11; equivalence, n = 13; and tremor-dominant, n = 3) underwent [123I]FP-CIT SPECT preoperatively and after 1 year of STN-DBS. DAT availability as determined by the specific binding ratio (SBR) was assessed by volume of interest (VOI) analysis of the caudate nucleus and the putamen ipsilateral and contralateral to the clinically more affected side. RESULTS Unified Parkinson's Disease Rating Scale (UPDRS) III scores improved significantly (mean preoperative on medication 25.6 ± 12.3, preoperative off medication 42.3 ± 15.2, postoperative on medication/off stimulation 41.4 ± 13.2, and postoperative on medication/on stimulation 16.1 ± 9.4; preoperative on medication vs postoperative on medication/on stimulation, p = 0.006), while the levodopa-equivalent daily dose was reduced (mean preoperative 957 ± 440 mg vs postoperative 313 ± 189 mg, p < 0.001). The SBR did not differ significantly before and 1 year after DBS, regardless of PD subtype. Preoperative DAT availability was not related to the change in UPDRS III score, but the change in DAT availability was significantly correlated with the change in UPDRS III score (contralateral head of the caudate VOI, p = 0.014; contralateral putamen VOI, p = 0.018). CONCLUSIONS Overall, DAT availability did not change significantly after 1 year of STN-DBS. However, on an individual basis, the improvement in UPDRS III score was associated with an increase in DAT availability, whereas DAT availability before STN-DBS surgery did not predict the clinical outcome. Whether a subtype-specific pattern of preoperative DAT availability can become a reliable predictor of successful STN-DBS must be evaluated in larger study cohorts.

Abstract
OBJECTIVE Deep brain stimulation (DBS) is an elective procedure that can dramatically enhance quality of life. Because DBS is not considered lifesaving, it is important that providers produce consistently good outcomes, and one factor they usually consider is patient age. While older age may be a relative contraindication for some elective surgeries, the progressive nature of movement disorders treated with DBS may suggest that older patients stand to benefit substantially from surgery. To better understand the risks of treating patients of advanced age with DBS, this study compares perioperative complication rates in patients ≥ 75 to those < 75 years old. METHODS Patients undergoing DBS surgery for various indications by a single surgeon (May 2013-July 2019) were stratified into elderly (age ≥ 75 years) and younger (age < 75 years) cohorts. The risks of common perioperative complications and various outcome measures were compared between the two age groups using risk ratios (RRs) and 95% confidence intervals (CIs). RESULTS A total of 861 patients were available for analysis: 179 (21%) were ≥ 75 years old and 682 (79%) were < 75 years old (p < 0.001). Patients ≥ 75 years old, compared with those < 75 years old, did not have significantly different RRs (95% CIs) of seizure (RR 0.4, 95% CI 0.1-3.3), cerebrovascular accident (RR 1.9, 95% CI 0.4-10.3), readmission within 90 days of discharge (RR 1.22, 95% CI 0.8-1.8), explantation due to infection (RR 2.5, 95% CI 0.4-15.1), or surgical revision (for lead, RR 2.5, 95% CI 0.4-15.1; for internal pulse generator, RR 3.8, 95% CI 0.2-61.7). Although the risk of postoperative intracranial bleeding was higher in the elderly group (6.1%) than in the younger group (3.1%), this difference was not statistically significant (p = 0.06). However, patients ≥ 75 years old did have significantly increased risk of altered mental status (RR 2.5, 95% CI 1.6-4.0), experiencing more than a 1-night stay (RR 1.7, 95% CI 1.4-2.0), and urinary retention (RR 2.3, 95% CI 1.2-4.2; p = 0.009). CONCLUSIONS Although elderly patients had higher risks of certain outcome measures than younger patients, this study showed that elderly patients undergoing DBS for movement disorders did not have an increased risk of more serious complications, such as intracranial hemorrhage, infection, or readmission. Advanced age alone should not be considered a contraindication for DBS.

Abstract
BACKGROUND Deep brain stimulation (DBS) was first approved by the United States Food and Drug Administration in 1997. Although the fundamentals of DBS remain the same, hardware, software, and imaging have evolved significantly. OBJECTIVE To test our hypothesis that the aggregate complication rate in the medical literature in the past 12 years would be lower than what is often cited based on early experience with DBS surgery. METHODS PubMed, PsycINFO, and EMBASE were queried for studies from 2008 to 2020 that included patients treated with DBS from 2007 to 2019. This yielded 34 articles that evaluated all complications of DBS surgery, totaling 2249 patients. RESULTS The overall complication rate in this study was 16.7% per patient. There was found to be a systemic complication rate of 0.89%, intracranial complication rate of 2.7%, neurological complication rate of 4.6%, hardware complication rate of 2.2%, and surgical site complication rate of 3.4%. The infection and erosion rate was 3.0%. CONCLUSION This review suggests that surgical complication rates have decreased since the first decade after DBS was first FDA approved. Understanding how to minimize complications from the inception of a technique should receive more attention.

[PMID: 34228232 DOI: 10.1007/s11064-021-03391-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2020] [Revised: 06/17/2021] [Accepted: 06/30/2021] [Indexed: 10/20/2022]
Abstract
FK1706 is a novel non-immunosuppressive immunophilin ligand with neurotrophic activity and exerts its neurotrophic effect through NGF. The present study aimed to elaborate on the neurotrophic activity and the mechanism of action of FK1706 in end-to-side neurorrhaphy rats and SH-SY5Y cells. In the regenerating nerves of neurorrhaphy rats, FK1706 increased the thickness of myelin sheath and the level of nerve regeneration-related proteins. The mechanism of action of FK1706 on neurite regrowth was elucidated in vitro by incubating SH-SY5Y cells in different conditions (Control, NGF, FK1706, NGF + FK1706, NGF + FK1706 + geldanamycin). Under the conditions where NGF was used, the phosphorylation level of major proteins (Raf-1 and ERK) in the Ras/Raf/MAPK/ERK signaling pathway related to SH-SY5Y cell proliferation was significantly enhanced following the application of FK1706. The number of viable cells, cell viability and neurite length of SH-SY5Y cells was maximal when NGF and FK1706 were used simultaneously. The binding level of HSP90 and Raf-1 in FK1706 group was the highest. These results indicated that FK1706 could significantly promote nerve regeneration after neurorrhaphy. The putative mechanism of action stated that FK1706 could promote the binding of HSP90 and Raf-1, make Raf-1 continue to be activated, thereby affecting key proteins in the Ras/Raf/MAPK/ERK signaling pathway related to the neurotrophic effects of NGF to promote the proliferation and neurite regrowth of nerve cells.

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.

Abstract
Background Deep Brain Stimulation (DBS) is an increasingly popular therapy for Parkinson's Disease (PD). Despite the experience gained over time with DBS of either the subthalamus or the globus pallidus pars interna, there is still no consensus regarding the age limit for DBS indication. Objectives This narrative review of the literature discusses the issues of age and DBS, emphasizing the critical need for good quality evidence to support the surgical management of elderly patients with PD. Methods We searched PubMed using the terms Parkinson's Disease; Parkinson's Disease therapy; deep brain stimulation; antiparkinsonian agents therapeutic use; age factors; aged; aged, 80 and over; middle aged; treatment outcome; and risk assessments. Results We identified several limitations of the available evidence, such as under-representation of older patients in DBS studies, small sample sizes in studies with older participants, heterogeneity of outcomes, and conflicting results. Conclusions Despite preliminary suggestions that age might affect the outcomes of DBS, the evidence to support the hypothesis of age as an independent predictor of DBS outcomes is limited and results are controversial. Ultimately, finding an age-independent biomarker predicting DBS outcome is the final goal to expand this powerful treatment to all patients age in an effective and safe manner.

Abstract
OBJECTIVE Parkinson's disease (PD) is a progressive neurological movement disorder that is commonly treated with deep brain stimulation (DBS) surgery in advanced stages. The purpose of this study was to investigate factors that affect time to placement of a second-sided DBS lead for PD when a unilateral lead is initially placed for asymmetrical presentation. The decision whether to initially perform unilateral or bilateral DBS is largely based on physician and/or patient preference. METHODS This study was a retrospective cohort analysis of patients with PD undergoing initial unilateral DBS for asymmetrical disease between January 1999 and December 2017 at the authors' institution. Patients treated with DBS for essential tremor or other conditions were excluded. Variables collected included demographics at surgery, time since diagnosis, Unified Parkinson's Disease Rating Scale motor scores (UPDRS-III), patient-reported quality-of-life outcomes, side of operation, DBS target, intraoperative complications, and date of follow-up. Paired t-tests were used to assess mean changes in UPDRS-III. Cox proportional hazards analysis and the Kaplan-Meier method were used to determine factors associated with time to second lead insertion over 5 years. RESULTS The final cohort included 105 patients who underwent initial unilateral DBS for asymmetrical PD; 59% of patients had a second-sided lead placed within 5 years with a median time of 34 months. Factors found to be significantly associated with early second-sided DBS included patient age 65 years or younger, globus pallidus internus (GPi) target, and greater off-medication reduction in UPDRS-III score following initial surgery. Older age was also found to be associated with a smaller preoperative UPDRS-III levodopa responsiveness score and with a smaller preoperative to postoperative medication-off UPDRS-III change. CONCLUSIONS Younger patients, those undergoing GPi-targeted unilateral DBS, and patients who responded better to the initial DBS were more likely to undergo early second-sided lead placement. Therefore, these patients, and patients who are more responsive to medication preoperatively (as a proxy for DBS responsiveness), may benefit from consideration of initial bilateral DBS.

Abstract
AbstractObjective:To review the effects of whole body vibration for patients with Parkinson’s disease.Design:Randomized clinical trials comparing whole body vibration with no vibration or conventional physical therapy for patients with Parkinson’s disease were searched up to July 31, 2019.Results:Seven studies with 196 patients were included for quantitative analysis. No significant difference was found between groups in motor score of unified Parkinson’s disease rating scale (UPDRS-III) (WMD [weighted mean difference] = −1.75, 95% CI, −5.40 to 1.90, I2 = 45.8%), functional reach test (SMD [standardized mean difference] = 0.21, 95% CI, −0.29 to 0.71; I2 = 0%), and other balance tests (including Berg balance test and Tinetti score) (SMD = 0.39, 95% CI, −0.01 to 0.80; I2 = 0%). No statistical difference was detected in walking velocity as well (WMD = −0.05, 95% CI, −0.17 to 0.06; I2 = 0%). In contrast, the pooled analysis from four studies on the Time Up and Go test showed favorable results for whole body vibration (WMD = −1.59, 95% CI, −2.90 to −0.28, I2 = 0%).Conclusion:Whole body vibration may not be beneficial over placebo or conventional physical therapy in overall motor function, balance, and walking velocity in patients with Parkinson’s disease. However, it might have positive effects on sit to stand transitions or turning.
