Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The study aims are to:
A.1. Establish the feasibility and acceptability of the intervention in Black and African Americans with Alzheimer's disease and related dementia disorders and hypertension.
H1: The intervention will be feasible and acceptable to Black and African Americans with Alzheimer's disease and related dementia disorders. Feasibility will be measured by recruitment, attendance, and attrition. Acceptability will be measured by a garnering feedback in a debriefing after each session.
A.2. Determine the effect size of the difference between the intervention, attention control, and control groups in resting state network connectivity and working memory and blood pressure to inform the sample size for the R01 trial.
H2: We hypothesize that compared to both control groups; the intervention group will have greater improvement in process measures of self-management mechanisms (self-efficacy, self-regulation, and emotion regulation), chronic stress, diet, and physical activity. The functional magnetic resonance imaging and blood pressure will be obtained at baseline and 3 months. The intervention group (Mindfulness + DASH) will have improved resting state network connectivity and blood pressure as compared to the attention control (2-hour group social time and brief lecture on a non-diet/mindfulness topic such as personal safety, fire safety, and disaster preparedness) and the control group (care as usual with no intervention). The Center for Cognitive and Behavioral Brain Imaging, Arts \& Sciences co-investigators will analyze imaging data using their newly published statistical network model to quantify the subnetwork structures of the resting state network and evaluate changes of their topological properties.

Study Groups

Mindfulness plus DASH group
Receives Mindfulness and DASH Diet education once a week for 8 weeks (2.5-hour sessions)
Mindfulness and DASH Diet Education
Mindfulness and DASH diet education will include a didactic presentation on stress, theoretical material related to mindfulness, the somatic mind/body connection, relaxation, yoga, meditation, self-awareness, and bodily cues relating to emotional reactivity. Practices will include the body scan, gentle yoga movement, walking/sitting meditation, breathing, relaxation. Additionally, daily 20 min individual practices are done at least 5x/week delivered via a compact disc player or on a preloaded device. Each participant is asked to track his/her daily meditation practice and given a diary for adherence records. A combination of didactic, experiential, and "hands-on" activities will be done to deliver DASH diet guidelines.
Education group
The attention control group will attend eight, 2.5 hours sessions on non-health topics such as personal safety, fire prevention, cold weather protection, disaster preparation, internet safety, aging in place, how to know when it's time to move and managing your money.
Education Group
The sham intervention includes general education on non-health related topics such as fire-safety and learning how to dispose of medication properly, once a week for 8 weeks (2.5-hour sessions)
Mindfulness and DASH Diet Education
Mindfulness and DASH diet education will include a didactic presentation on stress, theoretical material related to mindfulness, the somatic mind/body connection, relaxation, yoga, meditation, self-awareness, and bodily cues relating to emotional reactivity. Practices will include the body scan, gentle yoga movement, walking/sitting meditation, breathing, relaxation. Additionally, daily 20 min individual practices are done at least 5x/week delivered via a compact disc player or on a preloaded device.

Education group
The attention control group will attend eight, 2.5 hours sessions on non-health topics such as personal safety, fire prevention, cold weather protection, disaster preparation, internet safety, aging in place, how to know when it's time to move and managing your money.
Control Group
Continue care as usual without intervention.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Diagnosis of Alzheimer's disease or related dementia disorder or, if no formal diagnosis of Alzheimer's disease, then a Self-Assessment Gerocognitive Evaluation score 17-10 or a Montreal Cognitive Assessment Screen 25-19
Exclusion Criteria
* Expect to move out of the area within six months
* fMRI imaging contraindicated (history of shrapnel, metal in the body, heart pacemaker, heart defibrillator, metal in the eye, gunshot wound, or some types of metal elsewhere within the body such as certain surgical clips for aneurysms in the head, heart valve prostheses, electrodes, and some other implanted devices) or claustrophobia. However, the participant can be included in the study without fMRI.
* Self-reported history of a stroke
