PLACEBO EFFECT: WHY 'EMPTY' TREATMENTS SOMETIMES WORK

The placebo effect refers to the phenomenon in which patients experience real improvements in their health after receiving an inert or “empty” treatment, often due to psychological and neurobiological mechanisms. Placebo responses are influenced by patient expectations, the doctor-patient relationship, prior experiences, and contextual cues. Neuroimaging studies have demonstrated that placebo treatments can activate endogenous pain modulation pathways, release neurotransmitters such as endorphins and dopamine, and modulate brain regions associated with emotion, cognition, and reward. Understanding the placebo effect is essential for optimizing clinical trial design, enhancing therapeutic outcomes, and leveraging mind-body interactions in medical practice [1,2].
