In a departure from the usual Wiki format, Wikenigma assigns 'Importance Ratings' to some pages.

The idea is to separate articles which are considered (by the editors) to cover exceptionally important unknown issues from those which (although also u…

Psychobiotics

It's been known for many years that the microbiomeplugin-autotooltip__plain plugin-autotooltip_bigMicrobiome interactions

"“The human gut harbors trillions of invisible microbial inhabitants, referred to as the microbiota, that collectively produce thousands of unique small molecules. The sources and biological functions of the vast majority of these molecules are…
(the bacterial and viral components of gut contents) can affect the physical wellbeing of mammals, including humans.

It's recently been suggested that the micro-organisms might also be able to affect humans' psychological balances as well.

The new field of 'Psychobiotics' (named in 2012) studies such effects.

Animal studies (i.e. rodents) have shown that gut bacteria can apparently alter animals' 'mood'. ( See: Psychobiotics and the Manipulation of Bacteria–Gut–Brain Signals in Trends in Neurosciences 2016 Nov; 39(11): 763–781).

Further, it's known that bacteria can and do produce a wide range of chemical by-products that happen to be classed as zoological 'neurotransmitters' :

“Several molecules with neuroactive functions such as gamma-aminobutyric acid (GABA), serotonin, catecholamines and acetylcholine have been reported to be microbially-derived, many of which have been isolated from bacteria within the human gut.”
Source: Bacterial Neuroactive Compounds Produced by Psychobiotics in Microbial Endocrinology: The Microbiota-Gut-Brain Axis in Health and Disease pp 221-239

Researchers are divided, however, on the validity of studies to date :

“Whether bacteria might play a role in the gut-brain axis is under research. However, as of 2018, there is a paucity of randomized controlled trials testing the effects of live, ingested bacterial strains on clear mental health outcomes, and those that have been done provide inconclusive results when viewed in aggregate.”

Further research is needed to establish whether psychobiotic approaches could be applicable in the treatment of psychiatric problems - as well as in the maintenance of day-to-day psychological balance.
