Common risk factors include hypertension, diabetes, dyslipidaemia, obesity and smoking, whereas rare causes include haematologic disorders, premature atherosclerosis, vasculopathy and arteritis. Treatment barriers include inadequate infrastructure, a lack of trained staff and high intervention costs. Bangladesh faces a scarcity of neurologists and well-equipped hospitals, necessitating strategies to mitigate the burden of stroke among young people. This editorial summarises the current knowledge regarding the aetiology, pathophysiology and challenges in diagnosing and treating stroke in young people in Bangladesh, while addressing rare vasculopathy. Initiatives to support young stroke survivors and their families were also discussed. Prospective cohort studies, such as the Norwegian Stroke in the Young Study, provide insights into optimising prevention and early intervention by assessing family history and subclinical vascular diseases, which have also been highlighted. Recommendations include advanced neuroimaging for risk assessment, incorporating patient care and rehabilitation into medical education, conducting relevant research and promoting healthy lifestyles through campaigns and training of the healthcare staff.</p>","PeriodicalId":48733,"journal":{"name":"Journal of Investigative Medicine","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143803330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
