Hospital Resources - Depression

Depression is a medical disorder and is an intense feeling of sadness and worthlessness. Depression affects thoughts, feelings, physical health, and behaviors. Depression is not just “feeling blue” or “down in the dumps.”  It is not an ordinary part of aging: whether depression is a long-term issues or newly diagnosed residents can get better with treatment.

Why is it important?

  • Depressed elderly men have a twofold risk of admission to hospital
  • Time spent in hospital for people with mental illness relative to other diagnoses is twice as long
  • 15% - 25% of residents have symptoms of major depression (1)
  • 25% to 30% of patients fail to respond to initial therapy (3)

Common Causes

  • Health problems:  frailty, illness and disability; chronic or severe pain; cognitive decline; previous stroke, damage to body image due to surgery or disease.
  • Loneliness and isolation: a dwindling social circle due to deaths or relocation; decreased mobility due to illness or loss of driving privileges.
  • Reduced sense of purpose: Feelings of purposelessness or loss of identity due to retirement or physical limitations on activities.
  • Fears – Fear of death or dying; anxiety over financial problems or health issues.
  • Recent bereavements –death of friends, family members, and pets; the loss of a spouse or partner.(4)

Key Considerations

It is difficult to make a diagnosis of depression, particularly in patients with co-existing dementia and/or chronic medical illness; left untreated, mental illness can seriously affect physical health (3)

Depression red flags include:

  • sadness
  • fatigue
  • abandoning or losing interest in hobbies or other pleasurable pastimes
  • social withdrawal and isolation (reluctance to be with friends, engage in activities, or leave home)
  • weight loss or loss of appetite
  • sleep disturbances (difficulty falling asleep or staying asleep, oversleeping, or daytime sleepiness)
  • loss of self-worth (worries about being a burden, feelings of worthlessness, self-loathing)
  • increased use of alcohol or other drugs
  • fixation on death; suicidal thoughts or attempts

Often presents atypically which may include:

  • cognitive impairment
  • physical symptoms
  • non-specific features of irritability
  • calling out and restlessness
  • may co-exist with dementia

Factors suggestive of higher risk of suicide include:

  • older males
  • somatic complaints
  • agitated
  • sleeplessness
  • evidence of plan/intent
  • significant loss of support

Types of treatment include medication, psychotherapy and peer support.  Treatment can be pharmaceutical (antidepressants) or non-pharmaceutical Factors to guide antidepressant choice can include previous response, concurrent conditions, type of depression, other medications, and risk of overdose.
