Cognitive Enhancement in Unipolar Depression With Yoga

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.

Screening procedure:

The screening will be a verbal process where the patient will be verbally asked about the symptoms to check eligibility criteria of this study. If the patient is not eligible after completing this questionnaire, then the participation in this study will end.

(PS: Screening procedures for the study eligibility may involve the review and collection of information from patient's medical record.) This will be followed by obtaining written informed consent from the patient if the person considers participating in the study.

The eligible and consenting participants will be screened for severity of depression using a questionnaire.

After successful entry into the study, the patient will be asked about the demographic details including medical, treatment history.

Later, base line assessments to assess the cognitive functions will be done by the SRF. They are pen and paper tests. Total 3 types of tests will be done which may take around 25 to 30 minutes..

* Each person will be randomly assigned (like flip of a coin) to either yoga group or treatment as usual group. * . If the participant is in the yoga group, he/she will be asked to attend Specific Yoga Practices of duration around 1 Hour every day under a trained therapist for about 6 days in a week for 6 weeks. The cognitive assessments are repeated at the end of 6 weeks and also after a gap of 4 weeks of no yoga practice. * The treatment as usual group will undergo regular treatment as usual.. * The assessments will be repeated after 6 weeks of yoga and after 4 weeks of discontinuation for both participants of yoga group and treatment as usual group.
