Long-term Depression

33.3K
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

462
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

932
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,...

Summary
This summary is machine-generated.

Inflammation plays a role in major depressive disorder (MDD). Pro-inflammatory cytokines, elevated in some patients, may normalize with antidepressant treatment, suggesting future personalized MDD therapies.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Immunology

Background:

  • Inflammatory processes are increasingly implicated in the pathophysiology of major depressive disorder (MDD).
  • Elevated plasma levels of pro-inflammatory cytokines are observed in specific patient subgroups.
  • These cytokine levels may normalize following conventional antidepressant therapy.

Purpose of the Study:

  • To review current research on the relationship between depression and inflammation.
  • To explore potential future directions for individualized treatment of MDD based on inflammatory markers.

Main Methods:

  • Literature review of existing studies.
  • Analysis of the role of pro-inflammatory cytokines in MDD.
  • Discussion of personalized treatment strategies.

Main Results:

  • Evidence supports a link between inflammation and MDD.
  • Pro-inflammatory cytokine normalization observed with antidepressant treatment in some patients.
  • Inflammatory profiles may differentiate patient subgroups.

Conclusions:

  • Inflammation is a significant factor in MDD.
  • Personalized treatment approaches targeting inflammation hold promise for MDD.
  • Further research is needed to elucidate specific inflammatory pathways and therapeutic targets.
