Deep brain stimulation (DBS) is a surgical treatment for medication-resistant motor symptoms in Parkinson's disease (PD), involving the implantation of electrodes in subcortical targets, primarily the subthalamic nucleus (STN) and internal globus pallidus (GPi). While DBS is effective for motor control, psychiatric factors significantly impact postoperative quality of life. This narrative review aimed to summarise early (<2 weeks) psychiatric adverse events (AEs) following DBS in PD, addressing the prevalence of these events, their effects on pre-existing psychiatric symptoms and the influence of targeting and DBS parameters on these symptoms. A comprehensive search was performed across multiple databases, identifying 148 relevant studies, among which 55 focused on early psychiatric outcomes. Methodological diversity was noted, with 97% of studies concentrating on bilateral STN DBS. Our findings indicate that early postoperative psychiatric AEs are common, primarily occurring within days postsurgery and often transient. These AEs show improvement with parametric adjustments or the introduction of psychiatric medications. Notably, the role of the STN and GPi extends beyond motor control to emotional regulation, emphasising the importance of monitoring psychiatric outcomes in DBS patients. This review highlights the need for increased awareness and management strategies for early psychiatric complications in the context of DBS therapy, ultimately contributing to enhanced patient care and outcomes in advanced PD stages. Future studies should focus on standardising the evaluation of psychiatric AEs and exploring preventive strategies to minimise their occurrence post-DBS. PROSPERO registration number CRD42020184000.

Background: Resective epilepsy surgery is an established clinical intervention, but the cost-effectiveness at a national healthcare level is uncertain. This study evaluates the cost-effectiveness of resective epilepsy surgery compared with medical management in adults from national healthcare and personal social services perspectives.
Methods: A de novo decision analytic model was developed, comprising a 1-year decision tree and lifetime Markov model to evaluate lifetime costs and quality-adjusted life years (QALYs). Data were obtained from UK epilepsy surgery centres to evaluate the costs of preoperative assessment and the probability of undergoing resection after presurgical evaluation. Other clinical inputs were obtained from a systematic literature review. The main outcome of the analysis was the incremental cost-effectiveness ratio (ICER), with a cost-effectiveness threshold set at £20 000 cost per QALY gained.
Results: Data from 762 patients informed preoperative evaluation costs and the probability of undergoing epilepsy surgery after presurgical evaluation. The total lifetime cost of epilepsy treatment for people who had surgical treatment was £56 911, compared with £32 490 for medical management. Total QALYs per person for surgery were 15.91 and 13.76 for medical management. Resective epilepsy surgery was shown to be cost-effective with an ICER of £11 348 per QALY gained.
Conclusions: Our data inform and strengthen recommendations to prioritise referral of those with drug-refractory epilepsy to surgical centres. We provide a health economic rationale for the development and support of resective epilepsy surgery programmes across national healthcare systems.

Objectives: Early-onset Parkinson's disease (EOPD) is an increasingly serious disorder, yet there is currently a scarcity of epidemiological data and reports on this disease worldwide.
Methods: By using data from the 2021 Global Burden of Disease Study, we analysed the number of incident cases, prevalent cases and years lived with disability (YLDs) for EOPD (diagnosis after the age of 20 years and before the age of 50 years) from 1990 to 2021, along with their corresponding age-standardised rates. Additionally, we calculated the average annual percent change of the age-standardised rates and analysed the negative correlation between smoking and the disability-adjusted life years (DALYs) burden for EOPD.
Results: From 1990 to 2021, the incidence, prevalence and YLDs associated with EOPD have tripled globally. Most countries have seen a consistent increase in the age-standardised incidence and prevalence rates of this disease, especially those with high-middle Socio-Demographic Index scores. In 2021, smoking contributed to a 9.03% decrease in the global burden of DALYs, a decline from -14.14% in 1990.
Conclusions: EOPD is increasing at an alarming rate worldwide, necessitating the attention of global health organisations and the implementation of effective intervention measures to address this serious challenge.
目的:早发性帕金森病(EOPD)是一种日益严重的疾病,但目前世界范围内关于该疾病的流行病学数据和报告缺乏。方法:通过使用2021年全球疾病负担研究(Global Burden of Disease Study)的数据,我们分析了1990年至2021年EOPD(20岁后和50岁前诊断)的发病病例数、流行病例数和残疾生活年限(YLDs),以及相应的年龄标准化率。此外,我们计算了年龄标准化率的平均年变化百分比,并分析了吸烟与EOPD的残疾调整生命年(DALYs)负担之间的负相关关系。结果:从1990年到2021年,全球EOPD的发病率、患病率和YLDs增加了两倍。大多数国家的这种疾病的年龄标准化发病率和流行率持续上升,特别是那些社会人口指数得分中高的国家。2021年,吸烟使全球伤残调整生命年负担减少了9.03%,低于1990年的-14.14%。结论:EOPD在世界范围内以惊人的速度增长,需要引起全球卫生组织的注意,并采取有效的干预措施来应对这一严重挑战。

Background: Multiple sclerosis (MS), neuromyelitis optica spectrum disorder (NMOSD) and myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) can share similar features, posing diagnostic challenges. In this study, we identified sets of conventional MRI lesion distribution criteria proposed for disease differentiation and investigated their clinical utility.
Methods: We searched five electronic databases for English-written and peer-reviewed diagnostic accuracy studies that included brain MRI at least. Hierarchical and univariate random-effects logistic regression models were employed for diagnostic accuracy meta-analysis. Heterogeneity was explored with subgroup analyses. Certainty of evidence was assessed using the GRADEpro tool.
Results: Three sets of criteria ('Matthews', 'Cacciaguerra', 'MS lesion checklist') were investigated in 11 studies (2008 patients; MS, n=1037; NMOSD, n=842; MOGAD, n=129), with low applicability concerns. Overall pooled sensitivity and specificity of the Matthews brain MRI criteria (MS vs seropositive-NMOSD differentiation) were 0.92 (0.86 to 0.96) and 0.85 (0.79 to 0.90), respectively, with higher diagnostic values in non-Caucasian populations and during follow-up. Pooled sensitivity and specificity of the Cacciaguerra brain-spinal cord criteria (seropositive-NMOSD vs MS differentiation) were 0.96 (0.76 to 0.99) and 0.83 (0.71 to 0.90), respectively. The MS lesion checklist (MS vs NMOSD/MOGAD differentiation) had lower diagnostic accuracy measures (sensitivity, specificity: 0.74, 0.79, respectively). The Matthews criteria provided the strongest moderate certainty evidence and also showed high pooled diagnostic accuracy for MS versus seronegative-NMOSD (sensitivity: 0.93 (0.84 to 0.97)); specificity: 0.90 (0.80 to 0.95)) and for MS versus MOGAD differentiation (sensitivity: 0.86 (0.81 to 0.90); specificity: 0.87 (0.76 to 0.93)).
Conclusions: Lesion distribution criteria can accurately discriminate between MS, NMOSD and MOGAD. Further optimised validation studies, and revisions or extensions may support sustained implementation.

Background: Functional motor disorders (FMD) cause long-term disability and economic burden. There is a need for multidisciplinary interventions to manage both motor and non-motor symptoms. We aim to evaluate the clinical and economic effects of integrating digital telemedicine into multidisciplinary FMD management.
Methods: This single-blind, randomised controlled trial involved patients with FMD. They were randomly assigned to receive 5-day multidisciplinary rehabilitation with either a digital telemedicine or a standard care programme. The digital telemedicine group received remote management and wearable sensors. A blinded evaluator assessed primary and secondary outcomes at baseline, post-treatment, 12-week and 24-week follow-ups. The primary outcomes were changes in motor symptoms. The secondary outcomes were changes in non-motor symptoms, quality of life (QoL) and mobility in unsupervised settings. The incremental cost-effectiveness ratio (ICER) and quality-adjusted life years (QALYs) were calculated at 24 weeks.
Results: Of the total of 62 patients, half made up the digital telemedicine group (n=31, 40.82% female, mean age 42.55±12.65 years) and half the standard care group (n=31, 59.18% female, mean age 43.77±14.44 years). The mental QoL score for the standard care group was lower (p=0.045) and declined compared with the digital telemedicine group (p=0.034), with lower scores at follow-up (p=0.03). At 24 weeks, the ICER (€5503/QALY) showed that digital telemedicine, despite higher initial costs, yielded 0.037 additional QALYs and reduced healthcare use during follow-up.
Conclusions: Despite similar improvements in motor symptoms in both groups, digital telemedicine offers an effective adjunct to maintain mental health QoL and reduces healthcare costs in the long-term management of FMD.

Introduction: Late-onset multiple sclerosis (LOMS) now comprises over 10% of MS diagnoses in contemporary cohorts. The effectiveness of disease-modifying therapies (DMTs) in LOMS is unclear. We aimed to establish the comparative effectiveness of moderate-high-efficacy versus low-efficacy DMTs in LOMS.
Methods: Using data from the MSBase registry, this multicentre cohort study included people with MS with symptom onset after age 50. Covariates were balanced using inverse-probability-treatment-weighting (IPTW). Primary outcomes were time to first relapse and annualised relapse rate (ARR). Secondary outcomes were 6-month confirmed disability progression (CDP), confirmed disability improvement (CDI), relapse-associated worsening (RAW) and progression independent of relapse activity (PIRA).
Results: Of 1032 participants, 472 received moderate-high-efficacy DMTs and 560 received low-efficacy DMTs. IPTW-weighted ARR was 0.06 for moderate-high-efficacy and 0.09 for low-efficacy DMTs, corresponding to an ARR ratio of 0.68 (95% CI 0.50 to 0.93, p=0.01). HR for time to first relapse was 0.66 (95% CI 0.47 to 0.91, p=0.01) in favour of moderate-high-efficacy DMTs.Among 856 participants with adequate follow-up, 37% experienced CDP over a median of 4.43 years, with most events (83.6%) attributable to PIRA. The HR for time to CDP was 0.78 (p=0.08) and RAW was 0.69 (p=0.31) in favour of moderate-high-efficacy DMTs, though neither reached statistical significance. There was no difference in CDI or PIRA.
Conclusion: Moderate-high-efficacy DMTs reduced relapse risk in LOMS. Relapse activity was low. CDP was common and driven by PIRA. Although the CDP and RAW results did not reach statistical significance, the overall findings support the initial use of moderate-high-efficacy DMTs in LOMS.
在当代队列中,迟发性多发性硬化(LOMS)现在占MS诊断的10%以上。疾病修饰疗法(DMTs)在LOMS中的有效性尚不清楚。我们的目的是建立中高效与低效dmt在LOMS中的比较有效性。方法:使用来自MSBase注册表的数据,这项多中心队列研究纳入了50岁以后出现症状的MS患者。使用逆概率处理加权(IPTW)平衡协变量。主要终点为首次复发时间和年复发率(ARR)。次要结局是6个月确认的残疾进展(CDP)、确认的残疾改善(CDI)、复发相关恶化(RAW)和独立于复发活动的进展(PIRA)。结果:在1032名参与者中,472名接受了中高效dmt治疗,560名接受了低效dmt治疗。中高效dmt的iptw加权ARR为0.06,低效dmt的iptw加权ARR为0.09,ARR比值为0.68 (95% CI 0.50 ~ 0.93, p=0.01)。至首次复发时间的HR为0.66 (95% CI 0.47 ~ 0.91, p=0.01),有利于中高效dmt治疗。在856名随访充分的参与者中,37%的人在中位4.43年的时间里经历了CDP,其中大多数事件(83.6%)可归因于PIRA。到CDP时间的HR为0.78 (p=0.08), RAW为0.69 (p=0.31),均有利于中高效dmt,但均未达到统计学意义。CDI和PIRA没有差异。结论:中高效dmt可降低LOMS患者复发风险。复发率低。CDP是常见的,由PIRA驱动。虽然CDP和RAW结果没有达到统计学意义,但总体结果支持在LOMS中初始使用中效dmt。

Background: Evidence on relapse activity in relapsing-remitting multiple sclerosis (RRMS) after assisted reproductive technology (ART) treatment differs. We investigated whether relapse activity increased after ART initiation.
Methods: Women with RRMS from the Danish MS Registry who underwent ART treatment from 1995 to 2018 were eligible. The annualised relapse rate (ARR) and corresponding 95% CI at 3 and 9 months post-ART initiation versus 12 months pre-ART were investigated using a negative binomial regression model. Analyses were stratified for live births within 12 months post-ART and disease-modifying therapy (DMT) use pre-ART. Clinical and demographic factors associated with relapse risk were identified.
Results: At ART initiation, 162 women, median age 33 years (IQR: 30-37), median Expanded Disability Status Scale score 1.5 (IQR: 1.0-2.5) were included; 55 (34.0%) were exposed to DMT. 27 relapses were recorded (ARR (95% CI) 0.17 (0.11 to 0.26)) at 12 months pre-ART; 7 relapses and 0.17 (0.08 to 0.36) at 3 months post-ART initiation, and 16 relapses and 0.13 (0.08 to 0.23) at 9 months post-ART initiation. When stratified by ART outcomes, relapse counts in subgroups became small. Women continuing DMT at ART initiation showed a statistically non-significant increase in ARR at 3 months post-ART.
Conclusions: Women with RRMS in Denmark did not, on average, have increased relapse activity at 3 and 9 months post-ART initiation compared with 12 months pre-ART. Women with disease activity pre-ART initiation may have a potentially elevated relapse risk post-ART.

Background: Few studies have investigated patient-reported non-motor outcomes after stroke in young adults. We aimed to assess their prevalence and patterns in this population to identify unmet needs.
Methods: This prospective cohort study included consecutive patients (aged <55) admitted to University College London (UCL) Hospitals Hyperacute Stroke Unit with ischaemic stroke or intracerebral haemorrhage (ICH) between 2017 and 2020. At 6 months, we collected data on eight non-motor domains (anxiety, depression, fatigue, sleep disturbance, pain interference, reduced social participation, bowel and bladder dysfunction). We assessed outcome co-occurrence, compared prevalence by modified Rankin Scale (mRS) score (favourable: 0-1 versus unfavourable: 2-5), and performed multivariable logistic regression to identify predictors of each adverse outcome and high non-motor outcome burden (≥3 adverse outcomes).
Results: We included 493/527 (94%) eligible patients (median age 48, IQR 41-52; 33% female; 82% ischaemic stroke). Fatigue (55%) reduced social participation (47%) and sleep disturbance (46%) were most common. Prevalence rates did not differ significantly by mRS score. 91% reported ≥1 adverse outcome; 27% reported ≥4. Anxiety was predicted by ICH (OR 1.92; 95% CI 1.11 to 3.33; p=0.019) and higher education levels (per decile increase in education deprivation, OR 1.12; 95% CI 1.03 to 1.22; p=0.012). Pain interference was predicted by admission stroke severity (per National Institutes of Health Stroke Scale 10-point increase, OR 1.54; 95% CI 1.05 to 2.25; p=0.025).
Conclusions: Adverse non-motor outcomes are common in young adults 6 months post-stroke, even in those with an mRS score of 0-1 (indicating a favourable functional recovery). Furthermore, non-motor outcomes rarely occur in isolation, highlighting the need for early and comprehensive screening, recognition and management.
背景:很少有研究调查了年轻人中风后患者报告的非运动预后。我们的目的是评估其在这一人群中的流行程度和模式,以确定未满足的需求。结果:纳入493/527例(94%)符合条件的患者(中位年龄48岁,IQR为41-52;33%为女性;82%为缺血性卒中)。最常见的是疲劳(55%)、社交活动减少(47%)和睡眠障碍(46%)。mRS评分差异无统计学意义。91%报告了≥1个不良结局;27%报告≥4。焦虑被ICH (OR 1.92; 95% CI 1.11 ~ 3.33; p=0.019)和高等教育水平(教育剥夺每增加十分位数,OR 1.12; 95% CI 1.03 ~ 1.22; p=0.012)预测。入院时卒中严重程度预测疼痛干扰(根据美国国立卫生研究院卒中量表增加10点,OR 1.54; 95% CI 1.05至2.25;p=0.025)。结论:不良的非运动预后在中风后6个月的年轻人中很常见,即使在mRS评分为0-1(表明良好的功能恢复)的人中也是如此。此外,非运动预后很少单独发生,因此需要进行早期和全面的筛查、识别和管理。

Background: Stroke remains a significant global health challenge, especially in low- and middle-income countries, despite advances in treatment and prevention. Understanding stroke trends is crucial for guiding prevention and healthcare strategies.
Methods: We analysed global data from the Global Burden of Disease Study 2021 on stroke incidence, prevalence, disability-adjusted life years and mortality from 1990 to 2021. The study focused on the major subtypes of stroke-ischaemic stroke (IS), intracerebral haemorrhage and subarachnoid haemorrhage-examining the effects of age, sex and sociodemographic index (SDI) on stroke outcomes. Decomposition analysis assessed the contributions of population growth, ageing and other factors to stroke burden. The Nordpred Prediction Model was used to forecast stroke trends from 2022 to 2046.
Results: From 1990 to 2021, global stroke incidence and deaths increased by 70.20% and 32.17%, respectively, driven by population ageing (45.3%) and growth (29.1%). However, age-standardised incidence and mortality rates declined by 21.78% and 39.10%, reflecting improvements in healthcare and risk factor control. IS saw the largest increase in crude incidence (87.97%), with regional disparities, especially in low-SDI countries. By 2046, global stroke incidence and mortality are projected to rise by 20.3% and 35.7%, primarily in low- and middle-SDI countries.
Conclusions: The global stroke burden is rising, particularly in low-SDI regions, due to ageing and population growth. Declines in age-standardised rates emphasise the importance of healthcare improvements. Region-specific strategies are needed to address the rising burden and reduce disparities in stroke outcomes.

Background: Dementia with Lewy bodies (DLB) is the second most common neurodegenerative dementia, yet it remains under-recognised and misdiagnosed, which delays treatment, causes inaccurate prognosis and limits research opportunities. Imaging with 2-[18F]fluoro-2-deoxy-D-glucose positron emission tomography (FDG PET) is a supportive DLB biomarker. We evaluated a multivariate, quantifiable metabolic network biomarker, termed DLB-related pattern (DLBRP), for its further clinical translation across centres and disease stages.
Methods: We analysed demographic, clinical and FDG PET imaging data of 1180 participants from 14 tertiary centres and two multicentre datasets. We included 379 DLB, 28 mild cognitive impairment-LB (MCI-LB), 195 dementia due to Alzheimer's disease (ADD), 172 MCI-AD without α-synuclein co-pathology (MCI-AD-S-), and 73 MCI-AD with α-synuclein co-pathology (S+) patients, along with a comparative group of 333 normal controls (NCs). From the scans, we calculated the expression of DLBRP, AD-related pattern (ADRP) and Parkinson's disease-related pattern (PDRP) and compared them across groups. DLBRP scores were correlated with clinical measurements.
Results: Across independent cohorts, DLBRP robustly distinguished DLB from NCs (sensitivity >89%, specificity >90%), and scores correlated with Unified Parkinson's Disease Rating Scale Part III and independently predicted Mini-Mental State Examination. DLBRP was elevated already in MCI-LB. In a small longitudinal dataset, we observed steady increases in DLBRP expression with scores exceeding the diagnostic threshold prior to dementia onset. DLBRP and PDRP discriminated DLB from ADD (sensitivity, 74%-90%; specificity, 80%). In MCI-AD groups, ADRP was expressed, whereas DLBRP and PDRP were increased only in MCI-AD-S+, although comparatively less than in MCI-LB.
Conclusions: This study demonstrates the value of DLBRP in diagnosing prodromal and manifest DLB and distinguishing them from their AD counterparts. While overlap between patterns may reflect actual co-pathology, this possibility cannot be accepted without thorough pathological confirmation. The current findings support the use of DLBRP in patient evaluation and in future trial design.
背景:路易体痴呆(DLB)是第二常见的神经退行性痴呆,但它仍然未被充分认识和误诊,从而延误了治疗,导致不准确的预后并限制了研究机会。2-[18F]氟-2-脱氧-d -葡萄糖正电子发射断层扫描(FDG PET)是一种支持性DLB生物标志物。我们评估了一种多变量、可量化的代谢网络生物标志物,称为dlb相关模式(DLBRP),用于其跨中心和疾病分期的进一步临床翻译。方法:我们分析了来自14个三级中心和两个多中心数据集的1180名参与者的人口统计学、临床和FDG PET成像数据。我们纳入了379例DLB、28例轻度认知障碍- lb (MCI-LB)、195例阿尔茨海默病(ADD)、172例无α-突触核蛋白共病理的MCI-AD (MCI-AD-S-)和73例伴有α-突触核蛋白共病理的MCI-AD (S+)患者,以及333例正常对照组(nc)。通过扫描,我们计算了DLBRP、ad相关模式(ADRP)和帕金森病相关模式(PDRP)的表达,并在各组之间进行了比较。DLBRP评分与临床测量结果相关。结果:在独立队列中,DLBRP可有效区分DLB和nc(灵敏度>89%,特异性>90%),其评分与统一帕金森病评定量表第三部分相关,并可独立预测迷你精神状态检查。MCI-LB患者DLBRP已升高。在一个小的纵向数据集中,我们观察到DLBRP表达的稳定增加,在痴呆发病前得分超过诊断阈值。DLBRP和PDRP区分DLB和ADD(敏感性74%-90%,特异性80%)。在MCI-AD组中,ADRP表达,而DLBRP和PDRP仅在MCI-AD- s +组中增加,尽管相对低于MCI-LB组。结论:本研究证明了DLBRP在诊断前驱和表现型DLB并将其与AD区分开来的价值。虽然模式之间的重叠可能反映实际的共病理,但在没有彻底的病理证实的情况下,这种可能性不能被接受。目前的研究结果支持在患者评估和未来的试验设计中使用DLBRP。
