Efficacy and risks of artificial intelligence chatbots for anxiety and depression: A systematic review
A new systematic review in the medical literature finds that most studies of AI mental health chatbots report reductions in anxiety and depression symptoms, but are limited by small samples, weak control conditions, and inconsistent outcome measures. The authors warn that evidence remains insufficient to establish clinical efficacy or safety, and highlight underexamined risks such as emotional dependence and parasocial relationships with chatbots.
