[Post-stroke depression]

Area of Science:

• Neurology
• Psychiatry
• Rehabilitation Medicine

Context:

• Post-stroke depression (PSD) is the most frequent psychiatric complication following stroke.
• It significantly impacts stroke survivor recovery, functional outcomes, and mortality rates.
• Understanding PSD is crucial for improving patient care and long-term prognosis.

Purpose:

• This review synthesizes current research on major issues concerning post-stroke depression.
• It aims to elucidate the complex etiology, evolving neuroanatomical correlates, and significant risk factors associated with PSD.
• The review also touches upon diagnostic criteria and potential therapeutic avenues.

Summary:

• PSD is multifactorial, influenced by biopsychosocial elements.
• Acute-stage PSD correlates with left-hemisphere lesions impacting cortico-striato-pallido-thalamic circuits.
• Later stages (1-2 years) show association with right-hemisphere lesion severity and occipital pole proximity.
• Key psychosocial risks include prior depression, functional deficits, and social isolation.

Impact:

• This review provides a comprehensive overview of PSD, aiding clinicians and researchers.
• It emphasizes the dynamic nature of PSD's neurobiological underpinnings.
• Identifying risk factors and understanding lesion correlates can inform targeted prevention and treatment strategies for PSD.
