The placebo response in conditions other than pain

Although most of the neurobiological mechanisms of the placebo response have been described in pain and analgesia, new models have emerged in recent times. These models include the respiratory and cardiovascular system, the immune and endocrine system, Parkinson's disease, and depression. We believe that the integration of the pain studies with those in other pathological conditions will lead to a better understanding of the mechanisms underlying the placebo response.
