The relationship between the microbiome and posttraumatic stress disorder: a protocol for a scoping review

Despite the availability of various treatments, their effectiveness varies widely, underlining the necessity to understand the mechanisms behind the disorder. An emerging area of exploration is the influence of the human microbiome, the full complement of microbes within us, on PTSD.

Several studies have correlated microbiome imbalances or dysbiosis with mental health disorders, implying potential implications for PTSD via the gut-brain axis, a two-way communication system between our brain and gut. Still, the precise dynamics of this interaction and the extent of its therapeutic potential remain not fully elucidated. A scoping review will provide a comprehensive look at current research on the microbiome-PTSD interplay, shedding light on potential treatment avenues and areas needing additional exploration.
