Psychological Interventions for Cognitive Dysfunction in Major Depressive Disorder
Major depressive disorders (MDD) are common and disabling, and are linked to functional impairment and increased mortality. While current treatments for MDD are moderately effective, ultimately up to one-third of patients do not achieve full remission. Interestingly, while affective symptoms of depression resolve with the resolution of a depressive episode, cognitive or neuropsychological impairment persists, and has been identified as one of the most prominent predictors of ongoing disability, reduced quality of life, and illness recurrence. Yet available treatments in MDD do not typically address neuropsychological dysfunction. Cognitive training, however, despite a small and heterogeneous evidence base, represents a promising and novel therapeutic intervention for neuropsychological impairment in MDD, which may yield neuropsychological, affective, and functional benefits.
