A review of studies into postnatal depression has found that the most recent estimate of its prevalence in new mothers is 13%. Mothers' experiences of the condition included feelings of loneliness, anxiety, hopelessness and a loss of control at a time when they expected to feel joy and happiness. Research on treatment options showed limited success with antidepressants and slightly more success with psychotherapy. As important as anything in terms of making a recovery was mothers' network of social support from friends and families.
