Gut-brain axis and alcohol dependence: Exploring the role of Psychobiotics in treatment

Abstract

Chronic alcohol use adversely impacts the gut, including increased intestinal permeability and alteration in gut microbiota. Recent research has pointed to the association between alteration in gut microbiota and the induction of alcohol cravings. The term “psychobiotics” has been coined for microorganisms that, when ingested in sufficient amounts, may have beneficial effects on psychiatric illnesses. This letter to the editor highlights the possible mechanism underlying the therapeutic role of psychobiotics in addictive disorders and urges the scientific community to direct research focus on this avenue.
