By that stage, 50% to 80% of dopamine-producing brain cells may already be severely damaged or lost, limiting the effectiveness of treatment. \u00a0<\/p>\n<p>The new study focuses on the very early, or \u201cprodromal\u201d, phase of Parkinson\u2019s disease, which can last up to 20 years before motor symptoms become visible.\u00a0<\/p>\n<p>During this period, subtle changes occur inside cells, particularly in DNA damage repair mechanisms and the cellular stress response, both of which help cells survive and maintain genetic integrity. \u00a0<\/p>\n<p>Using machine-learning techniques, researchers analysed gene activity patterns in blood samples and identified a distinct molecular signature linked to these two processes.\u00a0<\/p>\n<p>This signature was present only in individuals believed to be in the earliest stages of Parkinson\u2019s and was absent in both healthy participants and patients with established disease. \u00a0<\/p>\n<p>According to the researchers, the fact that these biomarkers appear only briefly makes them especially valuable for diagnosis.\u00a0<\/p>\n<p>The findings point to a narrow but crucial window during which Parkinson\u2019s disease leaves a measurable trace in the blood, before extensive brain damage occurs. \u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"Scientists in Sweden and Norway have identified a set of blood-based biomarkers that could allow Parkinson\u2019s disease to&hellip;\n","protected":false},"author":2,"featured_media":477559,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[34],"tags":[64,63,137,500],"class_list":{"0":"post-477558","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-healthcare","8":"tag-au","9":"tag-australia","10":"tag-health","11":"tag-healthcare"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/477558","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/comments?post=477558"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/477558\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media\/477559"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media?parent=477558"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/categories?post=477558"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/tags?post=477558"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
