Abstract

may increase the intestinal permeability, as we previously observed in PD patients, and may make the intestinal neural plexus exposed to oxidative stress, which can lead to abnormal aggregation of prion-like α-synuclein fibrils in the intestine. In contrast to PD, SCFA-producing bacteria were not decreased in iRBD. As SCFA induces regulatory T (Treg) cells, a decrease of SCFA-producing bacteria may be a prerequisite for the development of PD. We propose that prebiotic and/or probiotic therapeutic strategies to increase the intestinal mucin layer and to increase intestinal SCFA potentially retard the development of iRBD and PD.

  • Some studies have found no difference in SCFA levels between individuals with RBD compared to controls.

    “Some studies have found no difference in SCFA levels between individuals with RBD compared to controls [128, 129], and one study reported no significant association between the non-motor features of prodromal PD and microbiome changes [130].”

    From The gut–brain axis in early Parkinson’s disease: from prodrome to prevention (2025) · cites this paper as [129]

    The Results (Meta-analysis of the Japanese and German data sets; page unavailable) report that no SCFA-producing genera were significantly decreased in iRBD. The Discussion suggests that reduced fecal SCFA concentrations may not occur in iRBD, but the study does not report a direct comparison of SCFA levels between iRBD participants and controls.

  • Feces from Parkinson's disease patients are enriched in opportunistic pathogens and pro-inflammatory taxa at the expense of anti-inflammatory microbes and SCFAs-producing bacteria, especially butyrate.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
