Depressive Disorders: MDD and Dysthymia

Depressive Disorders: MDD and Dysthymia

Depressive disorders are a group of mental health conditions characterized by pervasive feelings of sadness, diminished pleasure in life, and a significant impact on daily functioning. These conditions are most prevalent in individuals during their 30s and affect women at twice the rate of men. Contrary to popular belief, younger individuals are generally more susceptible to these disorders than older adults. Two key types of depressive disorders include Major Depressive Disorder (MDD) and...

Depression: Overview

Depression: Overview

Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...

Depressive Disorders: Etiology

Depressive Disorders: Etiology

Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.
Biological Factors in Depression
Biological predispositions significantly influence the risk of developing depressive disorders. Genetic studies highlight the role of variations in the serotonin transporter...

Long-term Depression

Long-term Depression

Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

G-protein Coupled Receptors

G-protein Coupled Receptors

G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.

Summary

Depressive symptoms affect how individuals adjust preferences after making choices. Individuals with more depressive symptoms show less reduction in preference for rejected items, impacting internally guided decision-making.

Area of Science:

Cognitive Psychology
Neuroscience
Clinical Psychology

Background:

Decision-making research often focuses on externally guided choices with clear correct answers.
Internally guided decision-making, lacking external criteria, involves phenomena like choice-induced preference change.
While depression's impact on externally guided decisions is known, its effect on choice-induced preference change is unclear.

Purpose of the Study:

To investigate the relationship between depressive symptoms and choice-induced preference change.
To determine if depressive symptoms influence preference shifts after making a choice between equally preferred options.

Main Methods:

Utilized the blind choice paradigm to assess choice-induced preference change.
Correlated measures of depressive symptoms with observed preference changes.

Main Results:

Depressive symptoms were significantly correlated with the change in preference for rejected items (Spearman's r = .28, p = .04).
Individuals experiencing higher levels of depressive symptoms exhibited a smaller decrease in preference for rejected items.

Conclusions:

Individual differences in depressive symptoms significantly affect choice-induced preference change.
Depression may alter the mechanisms underlying preference adjustment in internally guided decision-making.
