February 17, 2025 updated by: Daniel Clark, Indiana University

MIND Food and Speed of Processing Training in Older Adults With Low Education, The MINDSpeed Alzheimer's Disease Prevention Pilot Trial

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Adults with low education who give informed consent will complete a baseline cognitive assessment and then be randomized to one of four arms: 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 are conducted through applications running on a tablet computer device that we will provide to all participants for the study duration. Cognitive training is delivered through the online BrainHQ program from Posit Science, Inc. The foods will be shown on the tablet device in an online shopping format. Selected foods will be prepared and delivered by the study team.

Active intervention will last for 12 weeks. After the 12-weeks, free food deliveries will cease but participants who were allocated to cognitive training will continue to have access to BrainHQ. Those in the MIND food arms will be encouraged to maintain MIND food consumption.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

60 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Intervention / Treatment

Intervention / Treatment

Experimental: MINDSpeed Intervention
Consumption of foods high in polyphenols (i.e., MIND foods) AND speed of processing training
Behavioral: Speed of processing training
Speed of processing training is provided by the Internet-based BrainHQ program from Posit Science, Inc. BrainHQ contains five different speed training modules (Hawk Eye, Visual Sweeps, Fine Tuning, Eye for Detail, Sound Sweeps) which tap time-order judgment, visual discrimination, spatial-match, forward-span, instruction-following, and memory.
Behavioral: MIND foods
The "MIND" diet (created by the Rush Aging & Memory group) specifically emphasizes foods high in polyphenols such as berries, nuts, cocoa, black beans, olive oil, and green leafy vegetables. Participants select these foods from the digital study application and receive them through home delivery.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Executive Cognitive Function Composite Score
Time Frame: Immediately following the 12-week intervention (Immediate Post-Training)]
Executive Cognitive Function Composite Score as Measured by Individually-Administered Tests of Verbal Fluency, Complex Sequencing, Response Inhibition, and List Learning. The scale score range is -20 to 20. Low scores represent worse function and higher scores represent better function.
