predisposed to it, carry distinctive patterns of gut bacteria. <\/p>\n<p>\u201cIn recent years, there has been a growing recognition of the links between Parkinson\u2019s disease \u2013 a brain disorder \u2013 and gut health,\u201d said Anthony Schapira, lead investigator of the study at UCL. <\/p>\n<p>He added that the study has strengthened the existing evidence and shown that gut microbes may serve as an early warning signal of Parkinson\u2019s risk years before symptoms begin. <\/p>\n<p>The researchers at UCL, together with the French National Research Institute for Agriculture, Food and Environment, analysed clinical and fecal data from study participants in the United Kingdom and Italy. <\/p>\n<p>The study included 271 people with Parkinson\u2019s disease, 43 carriers of the GBA1 variant \u2013 a gene variant that can increase the risk of Parkinson\u2019s disease by up to 30-fold \u2013 who had no clinical symptoms, and 150 healthy control participants. <\/p>\n<div

class=\"c-widget-related__list\">\n<li class=\"c-widget-related__item\">UK woman plays clarinet during brain surgery to alleviate Parkinson&#8217;s symptoms<\/li>\n<\/ul>\n<\/div>\n<p>The results, published in Nature Medicine, found that more than a quarter of the microbial species making up the gut microbiome differed between people with Parkinson\u2019s disease and healthy control participants. <\/p>\n<p>Some microbes were more common among those with Parkinson\u2019s disease, while others were more common among healthy study participants.<\/p>\n<p>The researchers found this pattern was most noticeable among people in more advanced stages of Parkinson\u2019s.<\/p>\n<p>Most of these microbes also consistently differed in abundance when comparing healthy controls to people with the GBA1 gene variant who have not yet experienced any symptoms of the disease. <\/p>\n<p>\u201cImportantly, these same changes can be found in a small proportion of the general population that may put them at increased risk for Parkinson\u2019s,\u201d Schapira said.<\/p>\n<div class=\"c-widget-related\" data-stories-id data-event=\"widget_related\">\n<div

health, your brain: Why everyone talks about the microbiome<\/li>\n<\/ul>\n<\/div>\n<h2>Why early detection matters<\/h2>\n<p>Parkinson\u2019s is the fastest-growing neurodegenerative disease in terms of prevalence, disability, and deaths, and the second most common after Alzheimer\u2019s.<\/p>\n<p>It is characterised by the progressive loss of dopamine-producing neurons. By the time motor symptoms appear, and a clinical diagnosis is possible, more than half of those neurons have already been lost, the researchers noted. <\/p>\n<p>While treatments are being developed, the authors said that early detection is essential to make them effective. <\/p>\n<p>\u201cGut microbiome analysis can enable us to identify individuals who are at risk of developing Parkinson\u2019s disease, so that we can suggest ways for them to reduce their own risk, such as through dietary adjustments,\u201d said co-lead author Stanislav Dusko Ehrlich. <\/p>\n<p>The authors also acknowledge that further research is needed to understand what additional genetic or environmental factors determine whether a person ultimately develops Parkinson\u2019s. <\/p>\n<\/div>\n<p>

Here\u2019s everything to know<br \/>\n  <\/h3>\n<\/div>\n<\/article>\n<div class=\"articleBody\" data-key=\"articleBody\">The microbes living in a person\u2019s gut may signal their risk of developing Parkinson\u2019s disease before any symptoms appear, a new study has found.\u00a0Researchers from University College London (UCL) found that people with the disease, as well as those who are genetically predisposed to it, carry distinctive patterns of gut bacteria.\u00a0\u201cIn recent years, there has been a growing recognition of the links between Parkinson\u2019s disease \u2013 a brain disorder \u2013 and gut health,\u201d said Anthony Schapira, lead investigator of the study at UCL.\u00a0He added that the study has strengthened the existing evidence and shown that gut microbes may serve as an early warning signal of Parkinson\u2019s risk years before symptoms begin.\u00a0The researchers at UCL, together with the French National Research Institute for Agriculture, Food and Environment, analysed clinical and fecal data from study participants in the United Kingdom and Italy.\u00a0The study included 271 people with Parkinson\u2019s disease, 43 carriers of the GBA1 variant \u2013 a gene variant that can increase the risk of Parkinson\u2019s disease by up to 30-fold \u2013 who had no clinical symptoms, and 150 healthy control participants.\u00a0\u00a0The results, published in Nature Medicine, found that more than a quarter of the microbial species making up the gut microbiome differed between people with Parkinson\u2019s disease and healthy control participants.\u00a0Some microbes were more common among those with Parkinson\u2019s disease, while others were more common among healthy study participants.The researchers found this pattern was most noticeable among people in more advanced stages of Parkinson\u2019s.Most of these microbes also consistently differed in abundance when comparing healthy controls to people with the GBA1 gene variant who have not yet experienced any symptoms of the disease.\u00a0\u201cImportantly, these same changes can be found in a small proportion of the general population that may put them at increased risk for Parkinson\u2019s,\u201d Schapira said.Why early detection mattersParkinson\u2019s is the fastest-growing neurodegenerative disease in terms of prevalence, disability, and deaths, and the second most common after Alzheimer\u2019s.It is characterised by the progressive loss of dopamine-producing neurons. By the time motor symptoms appear, and a clinical diagnosis is possible, more than half of those neurons have already been lost, the researchers noted.\u00a0While treatments are being developed, the authors said that early detection is essential to make them effective.\u00a0\u201cGut microbiome analysis can enable us to identify individuals who are at risk of developing Parkinson\u2019s disease, so that we can suggest ways for them to reduce their own risk, such as through dietary adjustments,\u201d said co-lead author Stanislav Dusko Ehrlich.\u00a0The authors also acknowledge that further research is needed to understand what additional genetic or environmental factors determine whether a person ultimately develops Parkinson\u2019s.\u00a0<\/div>\n<p>[analyse_source url=&#8221;https:\/\/www.euronews.com\/health\/2026\/04\/21\/gut-microbiome-parkinsons-risk&#8221;]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[analyse_image type=&#8221;featured&#8221; src=&#8221;https:\/\/images.euronews.com\/articles\/stories\/09\/72\/97\/84\/1200x675_cmsv2_e5be67f5-c59a-5873-9bcc-82e97c3317bf-9729784.jpg&#8221;] Top News Stories Today Latest news bulletin | April 21st, 2026 \u2013 Midday Europe News EU Court rules Hungary&#8217;s anti LGTBQ+ law breaches core values Cinema &#8216;Aldeas&#8217;: Martin Scorsese\u2019s Pope Francis film to premiere at Vatican Iran Iran hangs man accused of ties to Israel and arson during protests Top News Stories [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[90],"tags":[226,36],"class_list":["post-1894051","post","type-post","status-publish","format-standard","hentry","category-international","tag-crawlmanager","tag-euronews-com"],"_links":{"self":[{"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=\/wp\/v2\/posts\/1894051","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1894051"}],"version-history":[{"count":0,"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=\/wp\/v2\/posts\/1894051\/revisions"}],"wp:attachment":[{"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1894051"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=1894051"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=1894051"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
