Understanding the Neurocognitive Effects of Fecal Microbiota Transplantation in Major Depressive Disorder Patients with and without Irritable Bowel Syndrome

Summary

Major depressive disorder (MDD) and Inflammatory Bowel Syndrome are common, life-disrupting and highly recurrent illnesses and can co-occur in patients. Unfortunately, 30–40% of patients do not respond to currently available antidepressant drugs or stop taking them because of unpleasant side effects such as obesity or diabetes. Therefore, there is clearly a need to explore alternative treatment options that are more effective and tolerable for individuals with MDD. Here we assess such an alternative, fecal microbiota transfer.
