Long-term Depression01:05

Long-term Depression

33.6K
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.

Area of Science:

  • Psychology
  • Clinical Psychology
  • Psychiatry

Background:

  • Cognitive errors (CEs) are linked to depressive thinking in major depressive disorder.
  • Self-report studies indicate CEs are more prevalent and severe in individuals with depression.

Purpose of the Study:

  • To describe cognitive errors in patients with major depressive disorder.
  • To examine the relationship between cognitive errors and depression severity.

Main Methods:

  • 45 participants undergoing cognitive therapy were assessed.
  • Cognitive Errors Rating System (CERS) and Beck Depression Inventory (BDI) were used.
  • Assessment occurred at session three.

Main Results:

  • Participants exhibited more negative CEs than positive CEs.
  • Selective abstraction was the most prevalent CE cluster.
  • High CERS "high distorters" showed more negative CEs than "low distorters" without differing BDI scores.

Conclusions:

  • Cognitive errors, especially negative ones, are characteristic of major depressive disorder.
  • The study highlights the role of selective abstraction and distortion in depression.
  • Findings have implications for psychotherapy research and practice.
