About this study

Official title: The Effects of Different Combinations of Plant Based Extracts on Cognitive Function and Cerebral Blood Flow in Humans

Acute, randomized, placebo controlled, double blind, 4 arm crossover study to determine the effect of different combinations of plant based extracts on cognitive function and cerebral blood flow.

Read the detailed description

The objectives of this study are to assess the effects of oral consumption of three differing combinations of plant based extracts, on cognitive function and cerebral blood flow (using Near infrared Spectroscopy) in comparison to placebo. The primary outcome will be change in cognitive function and mental fatigue during extended performance of the Cognitive Demand Battery (CDB) at 1, 3 and 6 hours post- consumption.

Being tested
Beverage containing plant based extracts

    Measured: 1-6 hours post intervention

Secondary outcomes (4)
  1. Change in executive function at 1, 3 and 6 hours post intervention.

    Measured: 1-6 hours post intervention

  2. Change in cerebral blood flow parameters (oxygenated and deoxygenated haemoglobin levels and their sum) in the frontal cortex during task performance commencing at 1, 3 and 6 hours post-intervention.

    Measured: 1-6 hours post intervention

  3. Change in episodic memory, as measured by immediate word recall, at 1, 3 and 6 hours post intervention.

    Measured: 1-6 hours post intervention

  4. Change in mood ratings, at 1,3 and 6 hours post intervention.

    Measured: 1-6 hours post intervention

Contact David Kennedy, PhD (david.kennedy@northumbria.ac.uk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in cognitive function and fatigue during extended performance of the Cognitive Demand Battery (CDB) at 1, 3 and 6 hours post consumption Change in long term declarative memory at 1, 3 and 6 hours post-intervention. (time frame: 1-6 hours post intervention). 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.
