The Role of Placebo in Ketamine's Antidepressant Effect

A study conducted at Stanford University found that ketamine, often used as a potential treatment for depression, showed no greater effect than a placebo in reducing the severity of depressive symptoms in adults with major depressive disorder. The unique experiment involved administering either saline or ketamine to patients before undergoing surgery, eliminating the possibility of experiencing the dissociative effects of ketamine. The findings suggest that the therapeutic benefits of ketamine may be partially attributable to the placebo effect, although further research is needed to confirm this.
