Abstract

Recent evidence has shown that bilateral brain-gut communication exists and plays an important role in neurological and neuropsychiatric conditions. Thus, research on the reallocation of bacteria known as psychobiotics has gained prominence. This review focused on identifying studies that correlate the use of psychobiotics with mood disorders, anxiety and depression. The results indicate that the intestine in balance is able to produce neurotransmitters essential to the treatment of certain mental diseases, in addition, five bacterial strains were identified with functions in the CNS and mood. More studies are needed to identify the mechanisms as they occur and methodological standardization to disseminate more homogeneous results.
