Is there a link between folic acid and memory?
« on: 30/09/2011 12:30:02 »
Lynne Carnac  asked the Naked Scientists:

I would like to know what the connection between folic Acid and memory is, are there any other supplements that I should take with Folic acid and is there any link between Folic Acid or lack thereof and Alzheimer's?

I live in Johannesburg and enjoy your newbielink: [nonactive] enormously.

With thanks


What do you think?

-   Mild cognitive impairment (MCI) – a simple but highly sensitive cognitive function test has been developed by Oxford scientists.  The test is free online on newbielink: [nonactive].  It is backed by a simple blood test that predicts the risk of Alzheimers.  MCI is known as a prodromal (early) stage of dementia
-   Alzheimer’s is usually diagnosed with a brain scan
-   A key element is levels of homocysteine a naturally occurring toxic amino acid in the blood stream.  Levels of homocysteine are used to predict one’s risk of Alzheimer’s.  Levels above 9 correlate with increased brain shrinkage.  Your body needs low levels of homocysteine for the critical bodily process known as methylation – your brain’s ‘tool kit’
-   The average level of homocysteine in people over 50 is 11.  People in their 70s may have levels of 15 and above
-   One may be able to lower homocysteine levels with supplements including vitamins B6, B12 and folic acid.  The Oxford research recommends doses many times higher than RDAs
-   B vitamins are found naturally in many foods including meat, fish, eggs and green vegetables


-   25 mg of all the B vitamins
-   10mcg of B12
-   200mcg of folic acid
-   200mcg of magnesium
-   2mg of manganese
-   10mg of zinc


-   7 (5) servings daily of fresh fruits and vegetables
-   Nuts and seeds (pumpkin, flax, sesame, hemp and sunflower)
-   Coldwater carnivorous fish – mackerel, salmon, herring, fresh tuna
-   Phospholipids – a family of fats – add a tablespoon of lecithin granules to cereal daily, or eat an egg a day, or 6 a week
-   Brain food formula providing phosphatidyl choline, phosphatidyl serine and DMAE


-   Alcohol aggravates the problem
-   Reduce stress – stress produces a chemical called cortisol
-   Reduce intake of all toxins – caffeine, alcohol, sugar, artificial additives and preservatives
-   Eat more high fibre foods, and drink plenty of water
