Trial summary

Dietary intake of omega-3 polyunsaturated fatty acids (n-3 PUFAs) is inversely associated with cognitive decline and dementia (e.g. Kalmijn et al. 2004, Heude et al. 2003, Morris et al. 2005, Dullemeijer et al. 2009). Read more about this study

About this study

Official title: Investigation of the Effects of Efalex Active 50+ on Cognitive Performance, Well-being and Cerebral Hemodynamics in Healthy Adults Aged 50-70 Years Reporting Subjective Memory Deficits

Dietary intake of omega-3 polyunsaturated fatty acids (n-3 PUFAs) is inversely associated with cognitive decline and dementia (e.g. Kalmijn et al. 2004, Heude et al. 2003, Morris et al. 2005, Dullemeijer et al. 2009). Recently, the effects of supplemental docosahexaenoic acid (DHA) on behavioural outcomes in older adults has been explored, however two trials addressing this issue have published conflicting results regarding the efficacy of DHA supplementation, with one reporting a benefit of treatment on cognitive performance (Yurko-Mauro et al. 2010), while the other did not (Dangour et al. 2010).

One area of research that has yet to be explored in this cohort is the effects of n-3 PUFAs on brain function in physiological terms. It is also possible that n-3 PUFAs, in combination with other compounds, may be more beneficial than treatment with n-3 PUFAs in isolation. The current study will explore several separate hypotheses within the same cohort. These are that Efalex Active 50+ may have a beneficial effect on:

  • Cognitive performance
  • Mental fatigue in response to cognitively demanding tasks
  • Self-reported mood/well-being
  • Task-related cerebral blood flow response

The proposed study therefore has two aims; the primary aim is to evaluate the cognitive and mood/well-being effects of Efalex Active 50+, a dietary supplement containing a number of potentially cognition enhancing components including DHA, phosphatidylserine, vitamin B12, folic acid and Ginkgo biloba, compared with placebo in a sample of older adults aged 50-70 years (Cognitive Study). The second is to evaluate the cerebral haemodynamic effects of the same treatment formulation in a sample drawn from the same population, with the addition of a third DHA-only arm (Hemodynamics Study). The intervention period will be 6 months.

What is being measured

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

  1. Cognitive performance

    Performance on a number of tasks assessing cognitive function across domains (attention, memory, executive function) will be measured.

    Measured: 6 months

Secondary outcomes (2)
  1. Cerebral Hemodynamics

    Cerebral blood flow response to cognitive tasks will be assessed using Near Infrared Spectroscopy (NIRS). General cerebral blood flow will be assessed using Transcranial Doppler (TCD)

    Measured: 6 months

  2. Mood/well-being

    Mood and well-being will be assessed using a number of measures:

    Bond-Lader visual analogue scales, Profile of Mood States (POMS), General Health Questionnaire (GHQ), Pittsburgh Sleep Quality Index (PSQI)

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing Efalex active 50+ and DHA rich fish oil in people with Cognitive Function and Mood, run by Northumbria University at 1 site in United Kingdom.

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 8 inclusion and 9 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 26 Sep 2012. 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 Kingdom. 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?

Cognitive performance (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 26 Sep 2012.
