la maladie de Parkinson<\/a>\u00a0des ann\u00e9es avant les premiers tremblements\u00a0? Cette hypoth\u00e8se vient de franchir une \u00e9tape d\u00e9cisive, au moment m\u00eame o\u00f9 le nombre de malades pourrait doubler d\u2019ici \u00e0 2050, faisant de Parkinson la pathologie neurologique qui progressera le plus rapidement en France. Des chercheurs de l\u2019University College of London, en collaboration avec l\u2019INRAE, ont explor\u00e9 une piste inattendue\u00a0: nos intestins. En d\u00e9veloppant une nouvelle m\u00e9thode d\u2019analyse du microbiote, ils ont montr\u00e9 que certaines communaut\u00e9s de bact\u00e9ries \u00e9voluent en fonction des stades de la maladie, ouvrant la voie \u00e0 un d\u00e9pistage pr\u00e9coce in\u00e9dit.<\/p>\nPour aboutir \u00e0 cette conclusion, publi\u00e9e dans la revue Nature Medicine, les chercheurs ont suivi et analys\u00e9 le microbiote intestinal – c\u2019est\u2011\u00e0\u2011dire l\u2019ensemble des bact\u00e9ries pr\u00e9sentes dans l\u2019intestin – d\u2019une cohorte de 464 personnes du Royaume\u2011Uni et d\u2019Italie, afin de caract\u00e9riser ces alt\u00e9rations\u2026<\/p>\n
