Long-term Depression01:05

Long-term Depression

33.2K
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.

Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

Depressants

394
Depressant drugs, including alcohol and sedative-hypnotics, diminish central nervous system activity by enhancing the action of gamma-aminobutyric acid (GABA), a neurotransmitter that reduces brain activity and promotes relaxation. These substances can have various therapeutic uses but also pose significant risks, especially when misused or combined.
Alcohol is a common depressant that can induce a sense of relaxation and reduced inhibition at low doses. Contrary to its occasional...

Depression: Overview

822
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,...

Dissociative Disorders01:27

Dissociative Disorders

520
Dissociative disorders represent complex psychological conditions characterized by disruptions in consciousness, memory, identity, or perception. These disruptions cause individuals to experience a disconnection from their thoughts, emotions, and memories. The phenomenon is not merely an occasional lapse in attention but a profound alteration in mental functioning that can severely impact daily life.
Dissociative Fugue
A hallmark feature of dissociative disorders is the dissociative fugue...

Summary

Major depressive disorder patients with physical symptoms or from rural areas show higher rates of dissociative experiences. This suggests a potential subtype linked to trauma, benefiting from trauma-focused therapy.

Area of Science:

  • Psychiatry
  • Clinical Psychology
  • Neuroscience

Background:

  • Major depressive disorder (MDD) is a prevalent mental health condition.
  • Dissociative experiences are common in various psychiatric disorders.
  • Understanding subtypes of MDD can improve treatment efficacy.

Purpose of the Study:

  • To investigate the prevalence of dissociative experiences in MDD patients.
  • To examine demographic and clinical factors associated with dissociation in MDD.
  • To identify potential MDD subtypes characterized by dissociation.

Main Methods:

  • Convenience sampling of 229 MDD patients.
  • Utilized Dissociative Experiences Scale (DES) and demographic questionnaire.
  • Employed t-tests, ANOVA, Chi-square tests, and ordinal regression for analysis.

Main Results:

  • Significant differences in mean DES scores were found between patients with physical vs. psychological complaints (23.61 vs. 3.19).
  • Rural patients reported higher mean DES scores (19.58) compared to urban patients (5.86).
  • A subgroup of MDD patients exhibited significant dissociative tendencies.

Conclusions:

  • MDD may include a subtype with significant dissociative tendencies, potentially linked to childhood trauma.
  • Dissociation may serve as a defense mechanism in this MDD subgroup.
  • Trauma-focused psychotherapy may be beneficial for MDD patients with high dissociation and somatization.
