简要总结
This pilot randomized controlled study evaluates Mindfulness and DASH Diet resting state network and blood pressure in 36 (n=12 intervention; n=12 attention control; n = 12 control) Black and African American older adults with early Alzheimer's disease and related dementia disorders and hypertension.
详细描述
The purpose of this pilot randomized controlled study is to adapt a previously tested intervention to improve resting state network and blood pressure in 36 (n=12 intervention; n=12 attention control; n = 12 control) Black and African American older adults with early Alzheimer's disease and related dementia disorders and hypertension.
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.
