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: 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...

Long-term Depression01:03

Long-term Depression

2.7K
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.

Benefits of Self-Esteem

18
Self-esteem—an individual's overall evaluation of their worth—plays a complex role in psychological functioning and well-being. It is often associated with many positive traits, such as confidence, optimism, and perseverance. Individuals with high self-esteem typically experience better sleep, manage peer pressure more effectively, and report greater life satisfaction. Conversely, low self-esteem has been consistently linked with increased risks of depression, anxiety, and poor...

Self-Discrepancy Theory

18.5K
One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Area of Science:

  • Mental Health Research
  • Socioeconomic Determinants of Health
  • Psychiatry and Psychology

Background:

  • The inverse relationship between income and depression is well-documented.
  • However, the specific relationship between wealth and depression remains less understood.
  • Existing literature requires a comprehensive review to clarify this association.

Purpose of the Study:

  • To conduct a scoping review of existing literature.
  • To answer the question: What is known about the relation between wealth and depression?
  • To synthesize findings on how wealth impacts mental health.

Main Methods:

  • Searched multiple databases (Medline, Embase, PsycINFO, EconLit, SocINDEX) up to July 19, 2020.
  • Included 96 articles in the full review and 32 longitudinal articles in a detailed charted review.
  • Analyzed article characteristics including definitions of depression and wealth, and their association.

Main Results:

  • Definitions and measurements of wealth varied significantly across studies.
  • A majority of studies (58%) reported an inverse relationship between wealth and depression.
  • Longitudinal data indicated that wealth influences depression across the lifespan, protects against stressors, and is modified by psychosocial factors.

Conclusions:

  • Wealth plays a significant role in shaping mental health outcomes.
  • The findings suggest wealth should be a key consideration in mental health research and interventions.
  • Savings interventions demonstrated success in reducing depression, with contextual variations.
