Clinical Trial Summary

Older women with cardiovascular disease (CVD) are at greater risk for memory loss, an important public health issue due to the negative effects to quality of life and health care costs. This research will be the first to examine the independent and combined effects of a lifestyle physical activity intervention and cognitive training on memory performance and memory-related serum biomarkers in this vulnerable population. The investigators will incorporate a practical lifestyle approach that can be delivered in the home and community settings to prevent or delay memory loss in older women with CVD.

Clinical Trial Description

Women experience disproportionately high rates of cognitive dysfunction, especially with increasing age, compared to men. Some research suggests that older women have a higher incidence of cognitive dysfunction with greater severity and more rapid decline.Furthermore, cardiovascular disease (CVD) increases the risk for cognitive dysfunction by 29-66% and affects 44 million women in the US. One particularly distressing type of cognitive dysfunction due to CVD is loss of memory. Memory loss leads to reduced independence, lower quality of life, and higher healthcare costs. To prevent or delay loss of memory among older women with CVD, there is an urgent need to develop lifestyle interventions that can be scaled. The long-term goal is to create and implement multi-modal lifestyle interventions (interventions that have multiple behavioral components) that will prevent or delay memory loss in older adults. The investigators initially focus on women with CVD due to their high risk. Physical activity interventions and cognitive training each prevent memory loss in healthy older adults. Thus, the investigators will evaluate the efficacy of MindMoves, a 24-week multi-modal intervention, on memory performance and memory-related serum biomarkers. The investigators will examine the serum biomarkers of brain-derived neurotrophic factor (BDNF), vascular endothelial growth factor (VEGF), and (c) insulin-like growth factor 1 (IGF-1). Data collection will occur at baseline, 24 weeks, 48 weeks, and 72 weeks. MindMoves is a combination of two evidence-based interventions. Mind is the cognitive training program BrainHQ modified to a lifestyle-focused electronic tablet format. Mind improves memory performance in healthy older adults and those with heart failure. Move is a modified lifestyle physical activity intervention from the Women's Lifestyle Physical Activity Program, which the investigators piloted in women with CVD. The investigators recently tested the feasibility of MindMoves. Using a 2x2 factorial design, the investigators will recruit 254 older women with CVD from cardiology clinics and randomize them to one of the following conditions: (1) Mind, (2) Move, (3) MindMoves, or (4) usual care control. This approach will allow us to evaluate main and interaction effects of Mind and/or Move on memory performance and memory-related biomarkers at 24, 48, and 72 weeks post-baseline. Specific Aim 1 (primary): Determine the independent and combined efficacies of Mind and Move on memory performance assessed by neurocognitive tests among women ≥ 65 years of age with CVD. Specific Aim 2 (secondary): Determine the independent and combined efficacies of Mind and Move on memory-related serum biomarkers (BDNF, VEGF, IGF-1) among women ≥ 65 years of age with CVD. Specific Aim 3 (exploratory): Evaluate depressive symptoms and genetic factors as potential moderators of the association between changes in target behaviors (physical activity and cognitive activity) and health outcomes (memory performance and relevant serum biomarkers). The investigators hypothesize that Mind and Move individually will each yield benefits to memory. However, it is hypothesized that the combined MindMoves will have a greater impact than the sum of the individual effects. Findings will provide key knowledge about the ability of practical multi-modal lifestyle interventions to target memory in older women with CVD. ;
