Diet and Cognitive Training for Mild Cognitive Impairment

Recruiting

The Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet incorporates the DASH (Dietary Approaches to Stop Hypertension) diet, which has been shown to lower high blood pressure, a risk factor for Alzheimer's disease. This study will test the whether the diet combined with Brain HQ cognitive brain training exercises improves cognitive performance in older adults.

The MIND diet is based on the Mediterranean diet, which some studies have shown is associated with a lower risk for dementia. BrainHQ is an online program of cognitive exercises based on neuroplasticity the brain's natural ability to change. This study will look at the effects of combining the MIND diet and BrainHQ cognition exercises on cognition.

Participants will complete a cognitive assessment at the start of the study and then be randomized to one of four study groups: 1) MIND foods and cognitive training, 2) MIND foods and control training, 3) control foods and cognitive training, or 4) control foods and control training.

All interventions will be conducted through applications (apps) running on a tablet computer device that will be provided to all participants for the length of study. Participants will select foods using an online shopping format on the provided tablet device. Selected foods will be prepared and delivered to each participant by the study team for 12 weeks. After the 12 weeks, free food deliveries will stop but participants in the cognitive training group will continue to have access to the BrainHQ cognitive test. Those participants in the MIND food study groups will be encouraged to maintain MIND food choices.
