Fatigue is a severely disabling symptom that can substantially impair quality of life and employment prospects, and has serious socioeconomic consequences. Different individual and disease-related variables interact to generate this complex symptom, leading to clinical heterogeneity. We currently lack a common understanding and definition of fatigue and its origins, thereby impeding professional exchange among disciplines regarding diagnosis and underlying pathophysiology. To aid the development of a common language that encapsulates the heterogeneity of fatigue, we propose a taxonomy consisting of neurogenic, myogenic and systemic clusters. Each cluster comprises the same five distinct concepts and their phenotypic expression. The interplay between multifactorial pathophysiological mechanisms might vary between diseases and over time, and additional factors such as comorbidities can modulate fatigue. Understanding this complexity is essential to improve both the diagnostic process and the development of targeted therapeutic interventions. In this Review, we compare the clinical and pathophysiological characteristics of a range of neurological and non-neurological diseases within predefined clusters of fatigue origin. We propose an integrative model for fatigue of different origin and over time based on the interplay of genetics and epigenetics, immunological changes, structural and functional brain abnormalities, and behavioural alterations. Large research consortia will be required to tackle the methodological shortcomings that currently hamper our understanding of fatigue and to initiate large longitudinal cohort studies with multidimensional readouts to further explore and address this burdensome symptom. Fatigue is a burdensome symptom that is commonly encountered in people with neurological or non-neurological diseases, but it is poorly understood and lacks a common definition and conceptualization. This Review presents new a conceptual model of fatigue that is designed to improve communication between experts from different methodological and medical backgrounds.
疲劳是一种严重的致残症状,会严重影响生活质量和就业前景,并产生严重的社会经济后果。不同的个体和疾病相关变量相互作用产生这种复杂的症状,导致临床异质性。我们目前缺乏对疲劳及其起源的共同理解和定义,从而阻碍了学科之间关于诊断和潜在病理生理学的专业交流。为了帮助开发一种概括疲劳异质性的共同语言,我们提出了一种由神经源性、肌源性和系统性集群组成的分类法。每个集群包括相同的五个不同的概念和他们的表型表达。多因素病理生理机制之间的相互作用可能因疾病和时间而异,其他因素如合并症可以调节疲劳。了解这种复杂性对于改善诊断过程和开发有针对性的治疗干预措施至关重要。在这篇综述中,我们比较了一系列神经系统和非神经系统疾病的临床和病理生理特征,这些疾病都是由疲劳引起的。我们提出了一个基于遗传学和表观遗传学、免疫变化、大脑结构和功能异常以及行为改变的相互作用的不同来源和时间疲劳的综合模型。需要大型研究联盟来解决目前阻碍我们理解疲劳的方法学缺陷,并启动具有多维读数的大型纵向队列研究,以进一步探索和解决这一繁重的症状。

Parkinson disease is a fatty acidopathy 帕金森病是一种脂肪性酸中毒。

On the basis of extensive mechanistic research over three decades, Parkinson disease (PD) and related synucleinopathies have been proposed to be combined proteinopathies and lipidopathies. Evidence strongly supports a physiological and pathogenic interplay between the disease-associated protein α-synuclein and lipids, with a demonstrable role for lipids in modulating PD phenotypes in the brain. Here, we refine this hypothesis by proposing PD to be a disease specifically involving metabolic dysregulation of fatty acids, a ‘fatty acidopathy’. We review extensive findings from many laboratories supporting the perspective that PD centres on fatty acid dyshomeostasis — alterations in the fatty acid-ome — as the critical feature of lipid aberration in PD and other α-synucleinopathies. This construct places transient α-synuclein binding to fatty acid side chains of cytoplasmic vesicles as a principal contributor to the biology of PD-relevant α-synuclein–membrane interactions. We propose that α-synuclein–fatty acid interactions in the fatty acid-rich brain are interdependent determinants of the gradual progression from neuronal health to PD, with attendant therapeutic implications. This Perspective centres on alterations in the fatty acid-ome as the critical feature of lipid aberration in α-synucleinopathies, specifically Parkinson disease. Here, the authors explain the biological and genetic basis for their hypothesis, with an emphasis on the transient binding of α-synuclein to fatty acids of various lipids.
在近三十年的广泛机制研究的基础上,帕金森病及其相关的突触核蛋白病被认为是蛋白质病和脂质病的结合。证据强烈支持疾病相关蛋白α-突触核蛋白与脂质之间的生理和致病相互作用,脂质在调节PD脑表型中具有明显的作用。在这里,我们完善了这一假设,提出PD是一种特别涉及脂肪酸代谢失调的疾病,即“脂肪酸酸中毒”。我们回顾了来自许多实验室的广泛研究结果,这些研究结果支持PD以脂肪酸失衡为中心的观点,即脂肪酸组的改变是PD和其他α-突触核蛋白病中脂质畸变的关键特征。该结构将α-突触核蛋白与细胞质囊泡脂肪酸侧链的瞬时结合作为pd相关α-突触核蛋白膜相互作用的生物学主要贡献者。我们认为富含脂肪酸的大脑中α-突触核蛋白-脂肪酸的相互作用是神经元健康逐渐发展为PD的相互依赖的决定因素,并具有相应的治疗意义。

Myotonic dystrophy type 1 (DM1) is the most prevalent muscular dystrophy in adulthood and is one of the most clinically diverse monogenic diseases. Although it is classified as a neuromuscular disease, DM1 is a multisystem disorder that affects nearly all organ systems, particularly skeletal and smooth muscles, the central nervous system and the heart. Its phenotypic variability extends beyond a continuum of severity, encompassing differences in age of onset and organ involvement. DM1 is caused by a trinucleotide (CTG) repeat expansion within the 3′ untranslated region of the DMPK gene, leading to a toxic RNA gain-of-function mechanism that disrupts RNA splicing, causing widespread cellular dysfunction. Despite progress in understanding DM1 pathogenesis, gaps remain in elucidating genotype–phenotype correlations, genetic modifiers and mechanisms that influence disease progression. Breakthroughs in the past five to ten years have uncovered important insights into the molecular underpinnings of DM1 and accelerated therapeutic innovation. Targeted interventions such as small molecules, antisense oligonucleotides and gene-editing technologies are progressing into clinical trials. Additionally, emerging research on somatic instability, epigenetic modifications and novel biomarkers suggests approaches for precision medicine. This Review synthesizes recent clinical and molecular discoveries, highlighting implications for therapy development. By integrating clinical heterogeneity with mechanistic insights, we provide a framework for future translational research and therapeutic innovation in this life-limiting disease. Myotonic dystrophy type 1 (DM1) is the most prevalent muscular dystrophy in adulthood and among the most clinically diverse monogenic diseases. This Review summarizes the latest insights into the molecular underpinnings of DM1, highlighting the implications for therapy development.
1型肌强直性营养不良症(DM1)是成人中最常见的肌肉营养不良症,也是临床上最多样化的单基因疾病之一。虽然它被归类为神经肌肉疾病,但DM1是一种多系统疾病,几乎影响所有器官系统,特别是骨骼和平滑肌、中枢神经系统和心脏。其表型变异性超出了严重程度的连续性,包括发病年龄和器官受累的差异。DM1是由DMPK基因3'非翻译区域内的三核苷酸(CTG)重复扩增引起的,导致毒性RNA功能获得机制,破坏RNA剪接,导致广泛的细胞功能障碍。尽管在了解DM1发病机制方面取得了进展,但在阐明基因型-表型相关性、遗传修饰因子和影响疾病进展的机制方面仍然存在空白。在过去的五到十年中,突破性的进展揭示了DM1分子基础的重要见解,并加速了治疗创新。小分子、反义寡核苷酸和基因编辑等靶向干预技术正在进入临床试验阶段。此外,体细胞不稳定性、表观遗传修饰和新型生物标志物的新兴研究为精准医学提供了途径。本综述综合了最近的临床和分子发现,强调了治疗发展的意义。通过将临床异质性与机制见解相结合,我们为这种限制生命的疾病的未来转化研究和治疗创新提供了一个框架。

Sporadic late-onset cerebellar ataxia (SLOCA) is a syndrome defined by subacute or chronic and progressive ataxia occurring after the age of 40 years in individuals without a family history of ataxia. The 2022 publication of revised consensus diagnostic criteria for multiple system atrophy and the emergence of promising biomarkers provides a thorough diagnostic framework that now enables the diagnosis of numerous acquired causes of SLOCA, including autoimmune disorders and neurodegenerative diseases. The ongoing development and increased availability of DNA sequencing technology have uncovered several molecular causes of SLOCA besides spastic paraplegia type 7 and very late-onset Friedreich ataxia. These additional causes include sporadic genetic disorders, such as spinocerebellar atrophy type 27B, caused by GAA expansion in the FGF14 gene, and cerebellar ataxia with neuropathy and vestibular areflexia syndrome (CANVAS), caused by biallelic expansions in the RFC1 gene. This Review presents an updated clinical approach to the diagnosis and management of SLOCA that focuses on the most important developments in this field. Future challenges are also discussed, including the identification of additional missing genetic causes of SLOCA, especially via the use of long-read genome sequencing, improvements in SLOCA prognostication and the implementation of clinical trials of neuroprotective interventions. Many autoimmune and genetic causes of sporadic late-onset cerebellar ataxia (SLOCA) can now be identified, but some individuals remain categorized as having idiopathic SLOCA. Wirth and colleagues discuss advanced genomic techniques that might identify additional ‘missing’ SLOCA causes, potential prognostic biomarkers and progress towards effective treatments.
散发性迟发性小脑性共济失调(SLOCA)是一种亚急性或慢性进行性共济失调综合征,发生于40岁以后,无共济失调家族史的个体。2022年出版的修订的多系统萎缩共识诊断标准和有希望的生物标志物的出现提供了一个全面的诊断框架,现在可以诊断许多获得性SLOCA的原因,包括自身免疫性疾病和神经退行性疾病。除了痉挛性截瘫7型和迟发性弗里德赖希共济失调外,DNA测序技术的不断发展和增加的可用性已经揭示了SLOCA的几个分子原因。这些额外的原因包括散发性遗传性疾病,如27B型脊髓小脑萎缩,由FGF14基因中的GAA扩增引起,以及小脑共济失调伴神经病变和前庭反射综合征(CANVAS),由RFC1基因的双等位基因扩增引起。本文综述了SLOCA诊断和治疗的最新临床方法,重点介绍了该领域最重要的进展。本文还讨论了未来的挑战,包括确定SLOCA的其他缺失遗传原因,特别是通过使用长读基因组测序,改善SLOCA预后和实施神经保护干预的临床试验。

In the 2024 revisions of the McDonald criteria for diagnosis of multiple sclerosis (MS), dissemination in time is no longer required. This paradigm shift is the result of advances in understanding of MS and the development of other biomarkers, enabling earlier diagnosis and treatment that will ultimately improve long-term outcomes.
在2024年修订的多发性硬化症(MS)麦克唐纳诊断标准中,不再需要及时传播。这种模式的转变是对多发性硬化症理解的进步和其他生物标志物的发展的结果,使早期诊断和治疗成为可能,最终将改善长期结果。
