Objective: The very few published data on post-stroke depression (PSD) among indigenous Africans have covered its prevalence and predictors. We sought to evaluate the dynamics of PSD in a cohort of Ghanaian stroke survivors followed for 9 months after an acute stroke.
Methods: Stroke survivors in this prospective cohort were adults aged >18 years with CT scan confirmed stroke, recruited into a randomized controlled trial to assess the feasibility of an mHealth technology-enabled, nurse guided intervention for blood pressure control. PSD was assessed a secondary outcome measure using the Hamilton Depression Rating Scale (HDRS) at enrollment, months 3, 6, and 9. Those with a score of >7 points on HDRS were categorized as depressed. A multivariate logistic regression analysis was performed to identify independent predictors of PSF.
Results: Mean age of study participants was 55.1 ± 12.7 years with 65% being males. Ischemic strokes comprised 76.6% of study population. Prevalence of PSD at baseline was 78.6%, 43.6% at month 3, 41.1% at month 6 and 18.2% at month 9 (p < .0001). Factors significantly associated with PSD at baseline were higher NIH Stoke Scale score (adjusted OR 1.51, 95% CI: 1.03-2.23) and pain (adjusted OR 7.18, 95% CI: 1.52-33.89). NIHSS score (adjusted OR, 1.99, 95% CI: 1.12-3.52) as associated with PSD at month 9.
Conclusion: 80% Ghanaian stroke survivors have early PSD declining to 20% at month 9. Stroke severity is the persistent factor associated with PSD at baseline and follow-up, and good be a target for screening and promptly treating PSD.
