Cognitive function and its change over time: effects on depression trajectories in oldest-old adults

This study emphasizes that although cognitive and emotional health are interrelated at baseline, changes in one domain do not reliably predict changes in the other among the oldest-old adults population. Instead, education, physical functioning, and self-rated health emerged as key predictors of both cognitive and emotional well-being. These findings highlight the importance of multidimensional assessments and targeted support to promote resilience and quality of life in extreme old age.
