A team of medical researchers from Shanghai Jiaotong University School of Medicine, Central South University and the Second Affiliated Hospital of Anhui Medical University, all in China, has found evidence suggesting that the placebo effect has grown stronger in trials of transcranial magnetic stimulation therapy for patients treated for depression.
In their study, reported in the journal Nature Mental Health, the group analyzed data from prior research efforts focused on testing the effectiveness of transcranial magnetic stimulation therapy.
Prior research has shown that the placebo effect—where a patient is given a “sham” medication or therapy to treat an ailment instead of a real one—can be an effective means of treating some conditions. And while the means by which the placebo effect works is not understood, it has been shown to alleviate symptoms in some people.
