Older (aged 50+) heterosexual couples who had no limitations in the activity of daily living at the baseline (2004) were included (N = 1,310). Latent class growth analysis grouped wives and husbands into distinct memory trajectories in 2004\u20132014. A structural equation model examined the actor and partner effects of memory trajectories on depressive symptoms in 2016 and disability status in 2018. The mediating effect of depressive symptoms was tested.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>A total of 4 distinct memory trajectories were found: persistently high, high and slow decline, moderate and slow decline, and low and rapid decline. Only the wife\u2019s low and rapid decline memory trajectory predicted her own more depressive symptoms (\u03b2 = 0.588, 95% CI: 0.209, 0.967) and her husband\u2019s more depressive symptoms (\u03b2 = 0.326, 95% CI: 0.004, 0.648). Meanwhile, depressive symptoms had strong and significant actor effects on disability (\u03b2 = 0.046, 95% CI: = 0.036, 0.057 for wives; \u03b2 = 0.060, 95% CI: = 0.046, 0.074 for husbands).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>The wife\u2019s low and rapid decline trajectory was associated with her own and her husband\u2019s more depressive symptoms, which in turn increased the disability risk for both partners.
