Abstract

Introduction As individuals age, the prevalence of neurocognitive and mental health disorders increases. Current biomedical treatments do not completely address the management of these conditions. Despite new pharmacological therapy the challenges of managing these diseases remain.There is increasing evidence that the Gut Microbiome (GM) and microbial dysbiosis contribute to some of the more prevalent mental health and neurocognitive disorders, such as depression, anxiety, obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), schizophrenia, bipolar disorder (BP), and dementia as well as the behavioural and psychological symptoms of dementia (BPSD) through the microbiota-gut-brain axis.Methodology: Scoping review about the effect of gut microbiota on neurocognitive and mental health disorders.Results This scoping review found there is an evolving evidence of the involvement of the gut microbiota in the pathophysiology of neurocognitive and mental health disorders. This manuscript also discusses how the psychotropics used to treat these conditions may have an antimicrobial effect on GM, and the potential for new strategies of management with probiotics and faecal transplantation.Conclusions This understanding can open up the need for a gut related approach in these disorders as well as unlock the door for the role of gut related microbiota management.KEY MESSAGESChallenges of managing mental health conditions remain in spite of new pharmacological therapy.Gut dysbiosis is seen in various mental health conditions.Various psychotropic medications can have an influence on the gut microbiota by their antimicrobial effect.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The microbiota-gut-brain axis has multiple sites for off-target activity, which may lead to positive or negative neurocognitive effects downstream.

    “Certainly, the MGB axis has multiple sites for off-target activity, which may lead to positive or negative neurocognitive effects downstream, emphasizing the importance of antibiotic stewardship (404–407).”

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.
