Community-based Brain Health Program to Address Dementia Risk (C-BBHP)

July 24, 2026 updated by: Posit Science Corporation
This is a validation study to evaluate the acceptability, feasibility and preliminary efficacy of the Brain Health Program, a multimodal curriculum covering dementia risk factors and evidence-based change interventions. The goal of this study is to evaluate the Brain Health Program in individuals with identified risk factors for the onset of dementia and to prepare for a large-scale efficacy trial in this population.

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

This study will employ an evidence-based Brain Health Program curriculum, which involves a twelve-week, group-administered, personalized program designed to improve brain health in individuals with identified risk factors for the onset of dementia. This is a single-arm open-label feasibility study, enrolling older adults with Alzheimer's disease risk factors in a public health, community-deployed, group-based and individualized multimodal Brain Health Program (targeting, among other domains, diet, exercise and cognitive exercise), with a set of baseline assessments intended to characterize the population, and outcome measure to evaluate the usability of the program, as well as preliminary efficacy to reduce dementia risk factors.

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.

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

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Brain Health Program
A multimodal educational and interactive diet, exercise and computerized cognitive exercise public health program.
Other: Brain Health Program
The Brain Health Program employs 1-hour/week group-based training and education regarding modifiable Alzheimer's disease dementia risk factors delivered over a 12-week period. Participants will be assigned into a group of up to 20 participants, and participants will engage the Brain Health Program collaboratively, as administered by the program content leader (instructor), while also being monitored and supported by the tech leader (in accordance with the Diabetes Prevention Program model).

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
Net Promoter Score
Time Frame: At 12 weeks
NPS (Net Promoter Score) is a whole number on a scale of -100 to +100, calculated by subtracting the percentage of Detractors from the percentage of Promoters. Promoters (score 9-10) are likely to exhibit value-creating behaviors, such as referring other potential program participants. Detractors (score 0-6) are less likely to do so. Passives (score 7-8) fall in between. Passives count toward the total number of respondents, which decreases the percentage of Promoters and Detractors and pushes the score toward 0. Higher score is better.
At 12 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants Who Complete at 80% of Intended Program Sessions.
Time Frame: At 12 weeks
At 12 weeks
Program Comprehension
Time Frame: At 12 weeks
One of the post-program survey questions asked participants whether the program was easy to comprehend. This was measured on a 7-point Likert scale, ranging from 1 ("totally disagree") to 7 ("totally agree"). Higher score means a better outcome.
At 12 weeks
Relevancy of Program
Time Frame: At 12 weeks
One of the post-program survey questions asked participants whether the program was relevant. This was measured on a 7-point Likert scale, ranging from 1 ("totally disagree") to 7 ("totally agree"). Higher score means a better outcome.
At 12 weeks
Program Awareness
Time Frame: At 12 weeks
One of the post-program survey questions asked participants whether the program effectively raised awareness about brain health and how to manage it. This was measured on a 7-point Likert scale, ranging from 1 ("totally disagree") to 7 ("totally agree"). Higher score means a better outcome.
At 12 weeks
Program Work Assignments
Time Frame: At 12 weeks
One of the post-program survey questions asked participants whether the work assigned in the program was reasonable. This was measured on a 7-point Likert scale, ranging from 1 ("totally disagree") to 7 ("totally agree"). Higher score means a better outcome.
At 12 weeks
Positive Lifestyle Change Post-program
Time Frame: At 12 weeks
One of the post-program survey questions asked participants whether the program helped to make a positive lifestyle change. This was measured on a 7-point Likert scale, ranging from 1 ("totally disagree") to 7 ("totally agree"). Higher score means a better outcome.
At 12 weeks
Program Satisfaction
Time Frame: At 12 weeks
One of the post-program survey questions asked participants whether the program was satisfying. This was measured on a 7-point Likert scale, ranging from 1 ("totally disagree") to 7 ("totally agree"). Higher score means a better outcome.
