Characteristics and correlates of poststroke depression: An Indian study

Area of Science:

• Neurology
• Psychiatry
• Clinical Psychology

Background:

• Post-stroke depression (PSD) negatively impacts long-term stroke outcomes and increases mortality.
• Limited research exists on the comprehensive profile of PSD.

Purpose of the Study:

• To investigate the phenomenology, characteristic features, and correlates of post-stroke depression.
• To explore the relationship between lesion location and PSD symptoms.

Main Methods:

• Assessed 142 stroke patients (≥60 years) using sociodemographic and clinical data.
• Utilized Post-stroke depression rating scale, Apathy Evaluation Scale, and Brief Psychiatric Rating Scale.
• Employed Mann-Whitney U, chi-square, Fisher's exact tests, ANOVA, and Kaplan-Meier survival analysis.

Main Results:

• Guilt correlated with parietal lobe lesions; catastrophic reactions and emotional dyscontrol with diffuse/frontal/occipital lesions.
• Psychiatric symptoms (BPRS score) positively correlated with depression (r=.692), unlike apathy.
• Mean time to develop depression post-stroke was 28.34 months.

Conclusions:

• PSD comprises clinically significant sub-components influenced by lesion location.
• PSD is distinct from apathy but shares associations with psychosis.
• Understanding PSD phenomenology aids in targeted interventions.
