Clinical depression and introversion significantly increase mortality risk in stroke survivors. Early identification and intervention for these factors are crucial for improving patient outcomes after stroke.

Area of Science:

  • Neurology
  • Psychiatry
  • Public Health

Background:

  • Stroke is a leading cause of long-term disability and mortality.
  • Psychological factors such as depression and personality traits may influence post-stroke outcomes.
  • Understanding these influences is critical for comprehensive stroke care.

Purpose of the Study:

  • To investigate the association between clinical depression and personality introversion with 15-month mortality in stroke patients.
  • To determine if these psychological factors independently predict mortality after stroke.

Main Methods:

  • A cohort of 94 stroke inpatients was assessed for depression and personality (neuroticism, introversion) two months post-stroke.
  • Vital status was determined for 84 patients at 15 months post-stroke.

  • Statistical analyses, including multivariate analysis, were used to examine the relationship between psychological factors and mortality.

    • Main Results:

    • The overall mortality rate was 8% (7 out of 84 patients).
    • Mortality risk significantly increased with the severity of depression (p = 0.01).
    • Patients who died had higher depression scores and were more introverted (less extroverted) than survivors (p = 0.006 and p = 0.004, respectively).
    • Both depression and introversion were independently associated with increased mortality in multivariate analyses.

    Conclusions:

    • Clinical depression and personality introversion are significant risk factors for increased mortality following stroke.
    • These psychological factors should be considered in the management and prognosis of stroke patients.
    • Further research may explore interventions targeting depression and introversion to improve stroke survival rates.
