Clinical features, genotypes, and treatment responses were analyzed.</div></div><div><h3>Results</h3><div>The study involved four girls and one boy. The major neuromuscular features were hypotonia and feeding difficulties in the neonatal period. They all had global muscle weakness. Different from typical symptoms of CMS, only one patient had transitorily unilateral mild ptosis with no obvious fluctuating nature. Minor facial dysmorphism, growth retardation (especially underweight), and significantly delayed motor development were frequently observed. One patient also showed language and cognitive development delay. In addition, two cases had a predominant decrease in insulin-like growth factor 1 at 2.3 and 1.6 years, respectively. The median age at diagnosis was 5 (1-12) months. Eight previously nondescribed mutations were detected among the five patients, in four children with compound heterozygous mutations and one child with homozygous mutations (maternal uniparental disomy). The frameshift mutation site (p. F428fs∗18) was found in two unrelated patients. All patients have received pyridostigmine treatment at median age of 6 (3-14) months. Four cases exhibited significant improvements in motor development.</div></div><div><h3>Conclusions</h3><div>Isolated PREPL deficiency is a multisystem disease more than just myasthenia. Early referral to diagnosis is crucial to enable timely initiation of treatment. Pyridostigmine is an effective treatment to improve motor development in most children. Monitoring hormone levels, including insulin-like growth factor 1, can assist in early intervention.</div></div>","PeriodicalId":19956,"journal":{"name":"Pediatric neurology","volume":"176 ","pages":"Pages 68-76"},"PeriodicalIF":2.1,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145979140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The universal impacts of these changes are creating as yet poorly acknowledged health crises, disproportionately affecting people with neurodisabilities.

This essay offers an overview of key contributing factors that are likely to exacerbate this climate crisis for individuals with neurodisabilities and provides recommendations regarding how to recognize and seize opportunities to confront the ever-growing threats of climate change for these people, their families, and communities. These perspectives are grounded in broader critical disability studies, strategies addressing social vulnerability, and environmental justice. Climate adaptation is extremely complex and far broader than disaster risk readiness and response. It would therefore be understandable to feel powerless in the face of human-created climate events that impel the world toward the brink. There are, however, many reasons for hope. This essay argues in favor of working to capture people's lived experiences and resourcefulness. We must recognize the creative and improvised strategies they are able to devise, and describe and promote the ensuing actions that we can take for the wellbeing of the people we service.
