Recent studies have delineated antibody subclass contributions to disease mechanisms and identified B-cell response patterns predictive of therapeutic outcomes. Despite clinical overlap with chronic inflammatory demyelinating polyradiculoneuropathy and Guillain-Barré syndrome, AN exhibit a distinct phenotype and a poor response to intravenous immunoglobulins. Multiple studies, including recent ones, report good response and long-term clinical remission with B-cell depleting therapies. Diagnostic assays such as cell-based assays and ELISA offer high accuracy, while biomarker-guided monitoring using antibody titers and serum neurofilament light chain supports individualized follow-up.Summary: Emerging evidence consolidates AN as a nosologically and therapeutically distinct entity.

The aim is to clarify nerve US clinical utility and guide its use in clinical practice.Recent findings: Nerve US supports differential diagnosis through characteristic sonographic patterns. In CIDP, it aids in identifying atypical forms, predicting treatment response, and may have a role in follow-up. In MMN, nerve US shows diagnostic value. In GBS, it can help differentiate acute-onset CIDP. In NA, alterations can be detected within hours from the onset. Anti-MAG antibody neuropathy lacks well characterized US features. In POEMS and vasculitis, data are scarce and conflicting.Summary: Nerve US is an established tool for diagnosing neuropathies, as it is noninvasive, accessible, reproducible, and complements electrophysiology. Its role is established in CIDP and its variants, while evidence supports its utility in MMN and the differential diagnosis of neuropathies with an inflammatory-like clinical presentation. In NA, nerve US may outperform neurophysiology. It appears less useful in GBS, POEMS, and anti-MAG neuropathy.","PeriodicalId":11059,"journal":{"name":"Current Opinion in Neurology","volume":" ","pages":"443-451"},"PeriodicalIF":4.4,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144274396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These elements, present in both coding and noncoding sequences, are highly instable, and their polymorphic variations have important roles in genes regulation and human phenotypic trait diversity. Importantly, expansion over a threshold size of a subset of these STR is the cause of approximately 60 neurological diseases, including some major muscle disorders such as myotonic dystrophy, oculopharyngodistal myopathy (OPDM) and oculopharyngeal muscular dystrophy. The discovery and characterisation of a number of these STR expansion disorders, in particular for OPDM, has been enabled in recent years by advanced genomic technologies.Summary: Many recently described STR expansion disorders are now recognized and genetic testing of patients is possible on a research basis, clinical testing for these newly described repeat loci is not yet readily available and is complicated by the reduced penetrance seen in some families, rendering clinical interpretation more difficult. The phenotypic spectrums associated with these STR expansion disorders are also evolving as unbiased sequencing approaches identified expansions at known loci in individuals with phenotypes that are quite different to those in which the STR expansions were first characterized. The pathomechanisms associated with these newer STR expansion disorders is still poorly understood, however there is evidence of both RNA toxicity and polyGly toxicity. Additional STR expansions underlying skeletal muscle diseases are likely to be identified in coming years and may shed further light onto the complex genetics, epigenetics and disease mechanisms underlying these disorders.","PeriodicalId":11059,"journal":{"name":"Current Opinion in Neurology","volume":" ","pages":"524-530"},"PeriodicalIF":4.4,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144246883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review aims at briefly summarizing our current knowledge, and at discussing the progress of the last two years.Recent findings: Common variation in numerous genes and variants in some nuclear-encoded mitochondrial genes were linked to an increased or modified risk of ALS, respectively. Mitochondrial function, i.e. specific mitochondrial haplotypes and loss-of-function variants in mitochondria-related genes, was identified as potent modifier of ALS survival, but not risk. Pioneering analyses of copy number variations in ALS-related genes revealed an increased load in ALS, but causality is unclear. A rare hyperactive variant of ER stress associated transcription factor CREB3 was linked to both substantially decreased ALS risk and slower disease progression. Furthermore, variants in IGFBP7 were linked to rare \"ALS reversals\", but existence of such phenotypes is controversial.Summary: Common variation increasing ALS risk contributes to our understanding of sporadic ALS, and novel structural variants have the potential to at least partly explain the missing heritability in ALS. Identification of mitochondrial function and ER stress signaling as potent disease modifiers provide valuable starting points for therapeutic approaches beyond targeting single causative genes.","PeriodicalId":11059,"journal":{"name":"Current Opinion in Neurology","volume":" ","pages":"568-573"},"PeriodicalIF":4.4,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12419016/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144793686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this review, we provide an update on the relevant contemporary literature addressing the clinical and pathophysiological aspects of IBM.Recent findings: Recent studies have investigated drugs for IBM, including the immunosuppressant sirolimus, but haven't shown satisfactory results. Some advancements have been made in investigating IBM pathophysiology: a cell culture model recapitulating key disease features has been established. Multiple studies have used RNA sequencing to elucidate disease-specific pathways, including selective type 2 fiber vulnerability. The importance of TDP-43 deposition and subsequent mis-splicing as a disease mechanism has been demonstrated. Further studies have shown the value of patient-reported outcome measures (PROM) and quantitative MRI as investigation tools.
