This review covers recent advances in depression research, including epidemiology, brain processes, and treatments. It addresses controversies surrounding antidepressant medications and their effects.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Epidemiology

Background:

  • Depression is a common, disabling, and under-treated condition in adults.
  • Recent research has enhanced understanding of information processing impairments and underlying brain processes in depression.
  • Previous reviews in The Lancet have covered depression in specific populations.

Purpose of the Study:

  • To review recent developments (last 5 years) in depression research.
  • To cover epidemiology, basic science, and treatment of adult depression.
  • To address current controversies regarding antidepressant medications.

Main Methods:

  • Literature review focusing on the last five years of research.
  • Synthesis of findings on epidemiology, basic science, and treatment modalities.

Related Experiment Videos

  • Analysis of evidence related to antidepressant mechanisms and controversies.

    • Main Results:

    • Detailed knowledge of information processing deficits is increasing, supported by quantitative brain studies.
    • Most patients show improvement with current depression treatments.
    • A new hypothesis suggests reversing hippocampal cell loss may be a key mechanism of antidepressants.

    Conclusions:

    • Despite advances, depression remains a significant public health issue.
    • The mechanisms of antidepressant action, particularly serotonin reuptuptake inhibitors, are under ongoing investigation.
    • Evidence is being gathered to address public and professional concerns about antidepressant safety and efficacy.
