Impact of MIND Diet and Aerobic Training on Cognition in Black Adults with High Blood Pressure

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized controlled trial aims to assess the effects of the Mediterranean-Dash Intervention for Neurodegenerative Delay (MIND) diet combined with aerobic training on cognitive function in Black adults with high systolic blood pressure. Participants will be divided into two groups: one receiving enhanced usual care and the other receiving food delivery, cooking training, and aerobic exercise. The study will include various assessments such as cognitive tests, blood pressure monitoring, and optional DNA testing to evaluate the impact of diet and exercise on cognition and cardiovascular health. The goal is to determine if these interventions can reduce cognitive decline and improve health outcomes in this population.
