How Gut Bacteria and Brain Chemistry Connect to Mental Health
Part of Mental health clinical trials.
This research study explores how gut bacteria and serotonin (a brain chemical linked to mood) may be connected in people with depression, anxiety, PTSD, or panic disorder. By analyzing your gut microbiome (the bacteria in your digestive system) alongside genetic information, researchers hope to better understand these mental health conditions.
