Depression significantly increases disease and death risk by disrupting immune function. This immune dysregulation, particularly increased proinflammatory cytokines, exacerbates age-related conditions and mortality in older adults.

Area of Science:

  • Immunology
  • Gerontology
  • Psychiatry

Background:

  • Depression is linked to substantial increases in morbidity and mortality.
  • Immune dysregulation is a key mechanism through which depression impacts health outcomes.

Purpose of the Study:

  • To review evidence on how depression affects immune function.
  • To examine the health consequences of depression-induced immune changes.

Main Methods:

  • Focus on recent human studies.
  • Review of research on depression's impact on immune function and subsequent health outcomes.

Main Results:

  • Depression stimulates proinflammatory cytokines, worsening age-related diseases like cardiovascular disease, diabetes, and cancer.

  • Depression impairs cellular immunity, leading to prolonged infections and delayed wound healing, which further fuels inflammation.

    • Conclusions:

    • Depression exacerbates age-related immune changes, increasing health risks for older adults.
    • The interaction between aging and depression significantly elevates risks for morbidity and mortality.
