Factors Associated With New-Onset Depression After Stroke

Area of Science:

• Neurology
• Psychiatry
• Public Health

Background:

• Post-stroke depression is a common complication affecting recovery and outcomes.
• Identifying individuals at high risk for depression post-stroke is crucial for timely intervention.
• Prestroke mental health status and lifestyle factors may influence depression risk after stroke.

Purpose of the Study:

• To identify stroke survivors at risk for depression who could benefit from early preventive strategies.
• To examine the association between prestroke factors and new-onset depression in stroke survivors.
• To inform predictive modeling for targeted interventions in the acute-subacute poststroke period.

Main Methods:

• Analysis of 118 Framingham Heart Study stroke survivors.
• Longitudinal assessment of prestroke depression history.
• Examination of demographic, lifestyle, and functional factors associated with poststroke depression.

Main Results:

• Most stroke survivors who developed poststroke depression had no history of depressive symptoms 5 years prior to their stroke.
• Female sex, advanced age, prestroke smoking, and functional dependence were significantly associated with new-onset poststroke depression.
• These factors highlight the importance of prestroke characteristics in predicting depression after stroke.

Conclusions:

• Prestroke factors, including psychosocial and behavioral determinants, are critical for identifying individuals at risk for poststroke depression.
• Characterizing prestroke factors can inform predictive models for targeted preventive trials.
• Early, targeted preventive strategies in the acute-subacute poststroke period may improve stroke outcomes by addressing new-onset depression.
