The Use and Clinical Significance of Transcranial Magnetic Stimulation in the Treatment of Major Depression
M ajor depression is among the most common and disabling of human diseases. The Global Burden of Disease Study notes that by the year 2020, the societal impact of unipolar major depression alone will be exceeded by only that of ischemic heart disease as estimated by a measure of disease morbidity, disability-adjusted life years. While modern pharmaceutical options have a clear record of success in randomized, controlled clinical trials, real-world experience in their use leaves room for improvement. The percentage of all patients who seek treatment for whom current options do not provide an acceptable solution ranges to 30%.
