Post-stroke Depression Increases Disability More Than 15% in Ischemic Stroke Survivors: A Case-Control Study

Area of Science:

• Neurology
• Psychiatry
• Rehabilitation Medicine

Background:

• Post-stroke depression (PSD) is a common complication affecting recovery.
• Understanding the influence of PSD on functional status and rehabilitation is crucial.

Purpose of the Study:

• To assess the impact of PSD on functional status and rehabilitation outcomes in ischemic stroke patients.
• To evaluate the effectiveness of antidepressant treatment in patients with PSD.

Main Methods:

• Retrospective, case-control study of 560 ischemic stroke patients.
• Patients matched for neurological impairment (CNS), age, and admission interval.
• Subgroups: with and without PSD; PSD patients treated with antidepressants (AD).

Main Results:

• PSD patients had lower admission and discharge scores (Barthel Index, Rivermead Mobility Index).
• Rehabilitation was less effective, and length of stay was longer in PSD patients.
• PSD patients who responded to antidepressants showed significantly better functional outcomes.

Conclusions:

• PSD exerts an unfavorable influence on functional outcomes post-stroke.
• Antidepressant therapy can improve outcomes in PSD patients, but effectiveness varies.
• Early identification and management of PSD are vital for stroke recovery.
