About this study

Official title: The Effect of Blueberry Consumption on Cognition and Body Composition in Elderly Who Are Experiencing Mild Cognitive Decline

Purpose: The purpose of this study is to examine the effect of blueberry consumption on cognitive decline and body composition in humans.

Hypothesis 1: Adults with mild cognitive decline who consume blueberries will experience an improvement in cognitive abilities as measured by a standardized battery of tests, relative to those who consume a placebo.

Hypothesis 2: Adults with mild cognitive decline who consume blueberries will evidence an increase in processing speed and an improvement in memory abilities as measured in an electrophysiological paradigm and compared to those who consume a placebo.

Hypothesis 3: Daily intake of 35 g freeze-dried blueberries will improve body composition (fat mass vs. lean mass).

Hypothesis 4: Daily intake of 35 g freeze-dried blueberries will decrease oxidative stress and inflammatory markers.

Being tested
Freeze-dried blueberries, Dextrose Placebo

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in cognitive test performance

    Measured by CANTAB

    Measured: Baseline, 180 days

  2. Change in brain activity (N200, P300) related to cognitive abilities as measured by event-related potentials (ERP)

    Recognition memory, speed of processing, and memory consolidation as measured by the electrophysiological technique known as event-related potentials (ERP)

    Measured: Baseline, 180 days

Secondary outcomes (2)
  1. Change in body mass distribution

    DXA scans to measure body composition at baseline and outcome will be compared for differences

    Measured: Baseline, 180 days

  2. Change in oxidative stress and inflammatory markers as measured in blood and urine

    Oxidative stress and inflammatory markers will be measured in blood and compared between baseline and outcome.

    Measured: Baseline, 180 days

Questions about this trial

What is this clinical trial studying?

A study testing Freeze-dried blueberries in people with Mild Cognitive Decline, run by University of North Carolina, Chapel Hill at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Mar 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in cognitive test performance (time frame: Baseline, 180 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01515098, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Mar 2022.
