Cardiovascular disease (CVD) affects approximately 44 million American adults older than age 60 years and remains the leading cause of death in the United States, with approximately 610,000 each year. With improved survival from acute cardiac events, older adults are often faced with the prospect of living with CVD, which causes significant psychological, social, and economic hardship. The various disease processes that constitute CVD also exert a deleterious effect on neurocognitive functioning. Although existing knowledge of neurocognitive functioning in CVD and its subtypes is substantial, a review of these findings by CVD type and neurocognitive domain does not exist, despite the potential impact of this information for patients, health care providers, and clinical researchers. This chapter provides a resource for clinicians and researchers on the epidemiology, mechanisms, and neurocognitive effects of CVDs. This chapter includes a discussion of neurocognitive consequences of CVD subtypes by neuropsychological domain and recommendations for assessment. Overall, the CVD subtypes that have the most findings available on specific neurocognitive domains are heart failure, hypertension, and atrial fibrillation. Despite a large discrepancy between the number of available studies across CVD subtypes, existing literature on neurocognitive effects by domain is consistent with the literature on the neurocognitive sequelae of unspecified CVD. Specifically, the research literature suggests that cognitive processing speed, attention, executive functioning, and memory are the domains most frequently affected. Given the prevalence of CVDs, neuropsychological assessment of older adults should include instruments that allow consideration of these potential neurocognitive consequences of CVD.
