ABSTRACT
INTRODUCTION:
Cardiovascular disease (CVD) is a recognized risk factor for dementia. Here we determined the extent to which an incident CVD event modifies the trajectory of cognitive function and risk of dementia.METHODS:
19,114 adults (65+) without CVD or dementia were followed prospectively over 9 years. Incident CVD (fatal coronary heart disease, nonfatal myocardial infarction [MI], stroke, hospitalization for heart failure) and dementia (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria) were adjudicated by experts.RESULTS:
Nine hundred twenty-two participants had incident CVD, and 44 developed dementia after CVD (4.9% vs. 4.4% for participants without CVD). Following a CVD event there was a short-term drop in processing speed (-1.97, 95% confidence interval [CI] -2.57 to -1.41), but there was no significant association with longer-term processing speed. In contrast, faster declines in trajectories of global function (-0.56, 95% CI -0.76 to -0.36), episodic memory (-0.10, 95% CI -0.16 to -0.04), and verbal fluency (-0.19, 95% CI -0.30 to -0.01) were observed.DISCUSSION:
Findings highlight the importance of monitoring cognition after a CVD event.Palavras-chave
