Prevention of Poststroke Mortality Using Problem-Solving Therapy or Escitalopram.

Area of Science:

• Neuroscience
• Psychiatry
• Gerontology

Background:

• Depression is a significant factor in post-stroke mortality.
• Previous research indicated that discontinuing escitalopram, but not problem-solving therapy (PST), increased depression in stroke survivors.
• Long-term survival data following stroke treatment interventions were previously limited.

Purpose of the Study:

• To determine if treatments initiated within 3 months post-stroke predict long-term mortality over 8-10 years.
• To investigate the long-term impact of escitalopram, PST, and placebo on survival.
• To test the hypothesis that PST is associated with the longest time to death.

Main Methods:

• Re-examination of patients from a 1-year randomized controlled trial (escitalopram, PST, or placebo).
• Follow-up interviews with families and surviving patients to ascertain health status or date/cause of death.
• Statistical analysis using the Weibull model, controlling for age, illness severity, gender, stroke severity, and depression history.

Main Results:

• Problem-solving therapy (PST) demonstrated a significant independent effect, increasing time to mortality.
• Older age and major depression were independently associated with decreased time to death.
• A significant independent effect of treatment on survival was observed.

Conclusions:

• This study provides the first evidence linking a 1-year psychological antidepressant treatment (PST) to increased survival in stroke patients.
• Problem-solving therapy may offer long-term survival benefits for individuals recovering from stroke.
• The findings highlight the potential of psychological interventions in mitigating post-stroke mortality.
