In the presented short clinical case of depression, the constructs of Research Domain Criteria (RDoC) of loss (negative valence systems) and cognitive control (cognitive systems) have been operationalized. It has been concluded that a normal cognitive control of emotion, requiring the functional and structural integrity of prefrontal cortex (PFC) and orbitofrontal cortex (OFC), is lacking in depression, but its amelioration can be achieved through the implementation of cognitive remediation/rehabilitation programs. A mini-review on neural and cognitive markers and regulation of emotion in depression is previously presented.
