    Late-onset depression presents with more physical symptoms like somatization and hypochondriasis. Age at onset and current age influence clinical features in major depression.

    Area of Science:

    • Psychiatry
    • Gerontology
    • Clinical Psychology

    Background:

    • Major depression can manifest differently based on patient age.
    • Involutional melancholia, a subtype of depression, requires further investigation.
    • Understanding age-related depression characteristics is crucial for effective treatment.

    Purpose of the Study:

    • To compare clinical characteristics of major depression based on age at onset.
    • To investigate the influence of current age on depression symptoms.
    • To explore the distinctiveness of involutional-onset depression.

    Main Methods:

    • Retrospective analysis of 31 patients with involutional-onset major depression.
    • Comparison with 60 patients diagnosed with earlier-onset major depression.

  • Assessment of clinical features including somatization, hypochondriasis, libido, guilt, suicidal intent, and family history.

    • Main Results:

    • Involutional-onset depression showed increased somatization and hypochondriasis, with decreased libido, guilt, suicidal intent, and family history.
    • Patients over 50 exhibited more agitation, initial insomnia, and hypochondriasis, irrespective of onset age.
    • Age at onset and current age significantly impact the clinical presentation of unipolar endogenous depression.

    Conclusions:

    • Clinical features of unipolar endogenous depression are influenced by age at onset and current age.
    • While not a distinct entity, involutional melancholia warrants further research.
    • Investigating the genetic and biochemical underpinnings of late-onset depression is recommended.
