Cognitive Enhancement in Unipolar Depression With Yoga

It is evident from recent studies that cognitive deficits persist even after remission of depressive episode. Hence, in this study, the investigators would like to see whether specific Yoga practice will help in enhancing cognitive abilities in this population.

Depression is a common mental health condition affecting many people around the world. It affects the person's mood, thinking (cognition), behavior and also physical health causing difficulty in performing duties in efficient way. Most of these problems can be treated by medicines and/or talk therapies. But the research shows that even after the recovery from most of these problems, most individuals continue to have difficulties in capacity to think properly, they are specifically called as dysfunction in executive functions of our mind. The executive functions are a set of skills which make us possible to play with ideas, taking time to think before acting, meeting novel, unanticipated challenges, resisting temptations, staying focused., etc.

To overcome these problems currently there is no standard solution. However, the previous studies have shown that specific Yoga practices help in overcoming these challenges in general population. Hence it is planned of testing whether regular practice of a specific Yoga along with ongoing treatment for depression would benefit persons in enhancing their thinking capabilities.
