This study investigated the impact of cardiovascular disease on cognitive function and found that both prevalent and incident cardiovascular disease can predict cognitive decline in middle-aged individuals. The study also found that the onset of cognitive decline in patients with incident cardiovascular disease is linked to the timing of the vascular event itself.
Aims Cardiovascular disease (CVD) has been suggested to accelerate cognitive decline and to be a risk factor for dementia, but still little is known about the cognitive course after a first cardiovascular event. Therefore, the present study aims to investigate the cognitive trajectories in both prevalent and incident CVD over a 12-year time period in the general population. Methods and results Cognitively healthy participants (age 24-82 years, n = 1823) of a prospective cohort study were serially assessed at baseline, 6 and 12 years. Verbal memory, executive function, and information processing speed were analysed in adults with prevalent, incident, and no CVD. Random effects models were used to test the association between CVD and change in cognitive function over time. At baseline, participants with prevalent CVD showed more decline in memory and information processing speed than healthy controls. Participants with incident CVD also showed more decline in these cognitive domains, but this was only significant in the follow-up period from 6 to 12 years. Associations were more pronounced in participants aged younger than 65 years at baseline, and in sub-analyses with angina pectoris or myocardial infarction as the most prevalent CVD conditions. Conclusion Prevalent and incident CVD predict cognitive decline in middle-aged individuals. Findings for incident CVD suggest that the onset of decline is linked in time with the vascular event itself. Timely CVD management may delay the onset of decline.
