Yoga in major depressive disorder: molecular mechanisms and clinical utility

Major depressive disorder (MDD) is a mind-body disorder. Cellular aging has been implicated in the pathogenesis of MDD with the altered mind-body communication markers like stress response, immune response, nutrition sensing, and a range of other regulatory feedback systems. In this age of super specializations, one specific target and interventions (preferably a drug) on it are being rigorously sought by the health care community and industry, but have failed in it in the last fifty years in spite of advances in technology. Since, depression is a complex disorder associated with increased incidence of other complex disorders, it must be treated by an integrated holistic approach that can address the complexity of MDD. Interventions targeting accelerated biological aging to increase cellular health in whole body have potential to manage complex conditions like MDD and its overlapping symptoms and comorbidities. Yoga has the potential to be the nexus between, clinical management of MDD and other lifestyle diseases.
