Memory biases in remitted depression: the role of negative cognitions at explicit and automatic processing levels.
BACKGROUND AND OBJECTIVES Cognitive models propose that depression is caused by dysfunctional schemas that endure beyond the depressive episode, representing vulnerability factors for recurrence. However, research testing negative cognitions linked to dysfunctional schemas in formerly depressed individuals is still scarce. Furthermore, negative cognitions are presumed to be linked to biases in ...
متن کاملStriatal Hypersensitivity During Stress in Remitted Individuals with Recurrent Depression.
BACKGROUND Increased sensitivity to stress and dysfunctional reward processing are two primary characteristics of major depressive disorder (MDD) that may persist after remission. Preclinical work has established the pivotal role of the striatum in mediating both stress and reward responses. Human neuroimaging studies have corroborated these preclinical findings and highlighted striatal dysfunc...
متن کاملReduced nucleus accumbens reactivity and adolescent depression following early-life stress.
Depression is a common outcome for those having experienced early-life stress (ELS). For those individuals, depression typically increases during adolescence and appears to endure into adulthood, suggesting alterations in the development of brain systems involved in depression. Developmentally, the nucleus accumbens (NAcc), a limbic structure associated with reward learning and motivation, typi...
متن کاملAttention and Memory Biases as Stable Abnormalities Among Currently Depressed and Currently Remitted Individuals with Unipolar Depression
BACKGROUND In the present study, we explored the possibility of the stability of attention bias and memory bias in currently remitted individuals with unipolar depression compared to currently depressed individuals with unipolar depression and never-depressed individuals. METHODS The Emotional Stroop and autobiographical memory task (AMT) were administered on 10 participants, who were current...
متن کاملEarly life stress affects limited regional brain activity in depression
Early life stress (ELS) can alter brain function and increases the risk of major depressive disorder (MDD) in later life. This study investigated whether ELS contributes to differences in regional brain activity between MDD patients and healthy controls (HC), as measured by amplitude of low-frequency fluctuation (ALFF)/fractional (f)ALFF. Eighteen first-episode, treatment-naïve MDD patients and...
