The update of self‐identity: Importance of assessing autobiographical memory in major depressive disorder

Abstract

AbstractMajor depressive disorder is a leading global cause of disability. There is a growing interest for memory in mood disorders since it might constitute an original tool for prevention, diagnosis, and treatment. MDD is associated with impaired autobiographical memory characterized by a tendency to overgeneral memory, rather than vivid episodic self‐defining memory, which is mandatory for problem‐solving and projection in the future. This memory bias is maintained by three mechanisms: ruminations, avoidance, and impaired executive control. If we adopt a broader and comprehensive perspective, we can hypothesize that all those alterations have the potential to impair self‐identity updating. We posit that this update requires a double referencing process: (1) to internalized self‐representation and (2) to an externalized framework dealing with the representation of the consequence of actions. Diagnostic and therapeutic implications are discussed in the light of this model and the importance of assessing autobiographical memory in MDD is highlighted.This article is categorized under: Psychology > Memory Psychology > Brain Function and Dysfunction Neuroscience > Clinical
