Exposure to social rewards protects against depression. Positive social interactions elicit activation in reward regions, which are hypoactive in depression especially in late life. Psychotherapy can increase engagement in social interactions and in turn increase activity in the reward system. We developed a paradigm to assess changes in social reward processing using EEG and MRI during psychotherapy for late life depression.
