Recent studies have linked the prolonged use of antibiotics to an increase in depression. It has linked increased use of antibiotics in babies and toddlers to increased incidence of autism. While it doesn't explicitly suggest that antibiotics causes depression or autism there is a strong correlation between the two. Do you believe that antibiotic use can cause depression or autism (I'm asking your opinion)? Why or why not? And how is it mechanistically possible for antibiotic use to affect mental health?
