Advances in Research on Intestinal Flora and Post - Traumatic Stress Disorder

Post - traumatic stress disorder (PTSD) refers to an individual experiencing, witnessing or encountering one or more actual deaths involving himself or others, or threatened with death, or serious injury, or threatened physical integrity. Of individuals with delayed onset and persistent mental disorders. Seriously disturb the life and work of patients, and bring a heavy burden to the family and society. Intestinal flora, as a large number of microorganisms colonized in the human digestive tract, plays an important role in maintaining the physiological functions of human metabolism, immunity, and endocrine. The gut - brain axis is a two - way information regulation system that connects the brain and gastrointestinal functions. The intestinal flora can participate in the activities of the gut - brain axis under both physiological and pathological conditions, affecting brain function and certain related behaviors. Therefore, in - depth study of the interaction between intestinal microbes and PTSD, and the design of individualized drugs for the intestinal flora, can provide new research ideas and methods for the clinical prevention and treatment of PTSD.
