This comprehensive test measures the vitamin D, omega-3, homocysteine, HbA1C and Glutathione Index to calculate your Dementia Risk Index functional Test (DRIfT) score. Tracking this, along with your Cognitive Function (CFT) and Dementia Risk Index (DRI) is the most comprehensive way to protect your brain.

This measures methylation, your need for B vitamins. Faulty methylation damages the brain and circulation and is the single best indicator of cognitive health. Homocysteine goes up when methylation is impaired, indicating a greater need for B vitamins, especially B6, B12 and folate.
The Glutathione Index measures the ratio between your “fully-loaded” glutathione and “spent” or oxidised glutathione in red blood cells. This is the best measure of your antioxidant potential which indicates your ability to neutralise harmful oxidants created both by your body and brain’s metabolism, and from smoking and pollution.
This measures EPA and DHA.These two important omega-3 fats found in seafood, are essential for brain health. The Omega-3 Index measures the amount of EPA and DHA in red blood cells (RBC). The result shows the % of total RBC fats, and is a long-term, stable marker of omega-3 status.
Vitamin D is made in the skin and provided in supplements and foods such as oily fish and eggs. Both are converted in the liver to form 25(OH)D3 which is the form of vitamin D in the blood, measured by this test. Your levels of 25(OH)D3 levels shows your body’s production plus your intake.
Hemoglobin A1c is a measure of how healthy average blood sugar levels have been in the recent few months, and is a better representation of blood sugar resilience than a single glucose measurement, since glucose levels vary throughout the day. HbA1c forms in the blood when a hemoglobin molecule in a red blood cell binds with a glucose molecule in the blood; the resulting molecule is also known as glycated hemoglobin (sugar coated or damaged red blood cells).

As well as recording your changes, hopefully improvements over time of your cognitive function via the Cognitive Function Test you just did, and your Dementia Risk Index via the online questionnaire you’ve completed, we want to record your blood levels of the five most essential markers of brain health. Combined together this is your Dementia Risk Index functional Test (DRIfT) score.

This information is vital for you to optimise your brain health, and vital for our research to establish what really prevents age-related cognitive decline and ultimately Alzheimer’s. By becoming a ‘citizen scientist’ in joining this project you also join COGNITION (and receive educational guidance to ‘upgrade your brain’ by dementia-proofing your diet and lifestyle.
Join COGNITION. We will advise you what to do – eat and supplement – to optimise your test results.
