Cognitive Function Improvement Metrics Post-Mental Health Services Implementation Among Elderly in Urban Lagos, Nigeria

Urban Lagos, Nigeria faces significant challenges in mental health services provision for its elderly population, exacerbating existing cognitive decline issues. A longitudinal study design was employed with a sample size of 250 participants aged over 60 who received mental health services. Cognitive function assessments were conducted pre- and post-intervention using standardised tests. Memory scores improved by an average of 15% (95% CI: 7%, 23%) and problem-solving abilities increased by 8% (95% CI: 2%, 14%) among participants who received mental health services compared to the control group. The implementation of mental health services significantly enhances cognitive function in urban elderly populations, demonstrating a positive impact on their daily activities and quality of life. Further research should investigate long-term effects and potential cost-effectiveness analyses of such interventions. Policy makers are encouraged to integrate these findings into future mental health service frameworks for urban aging populations.
