Suicidal thinking in older adults is linked to depression and mixed dementia, not dementia severity or memory awareness. Further research into cerebrovascular disease

Area of Science:

  • Geriatric psychiatry
  • Neuroscience
  • Epidemiology

Background:

  • Suicidal ideation is a significant concern in the elderly population.
  • Understanding the factors associated with suicidal thinking in older adults is crucial for effective intervention.
  • Cognitive impairment and depression are prevalent in this demographic and may influence suicidal ideation.

Purpose of the Study:

  • To investigate the relationship between suicidal thinking and cognitive impairment in individuals over 81.
  • To examine the association between suicidal thinking and depression in an elderly community-dwelling cohort.
  • To explore the role of specific dementia subtypes and awareness of cognitive deficits in suicidal ideation.

Main Methods:

  • A random sample of community residents aged over 81, part of a pre-existing dementia epidemiological study, was interviewed.

  • Exclusion criteria included frailty, severe communication difficulties, and refusal by participants or their caregivers.
  • Assessments included the Cambridge Mental Disorders of the Elderly Examination (CAMDEX), Geriatric Depression Scale (GDS), and Scale for Suicidal Ideation (SSI), with informant versions available.

    • Main Results:

    • Nine participants (all women) reported suicidal thinking.
    • Suicidal thinking was associated with higher depression scores on the CAMDEX, a weaker will to live, and a greater wish to die.
    • A significant association was found between suicidal thinking and mixed dementia (dementia of Alzheimer's type/multi-infarct dementia), but not with GDS scores, Alzheimer's-type dementia alone, memory awareness, or dementia severity.

    Conclusions:

    • Suicidal thinking in this elderly cohort is associated with depression and mixed dementia.
    • No association was found between suicidal thinking and awareness of memory problems or the overall severity of dementia.
    • Methodological limitations necessitate caution in interpreting results; further research on cerebrovascular disease's role in depression is recommended.
