DHA Deficiency Linked to Cognitive Impairment and Alzheimer’s

DHA (docosahexaenoic acid) is the most important fatty acid that your brain uses to build and sustain your brain cell networks.  If it is present in brain cell membranes then brain cells work better.  If it is lacking then brain cell health deteriorates.  The researchers proved that DHA present in brain cells was associated with better cognitive function and that a lack of DHA in key brain regions was associated with cognitive impairment and Alzheimer’s disease.  Furthermore, they discovered that a liver defect was present in Alzheimer’s patients that prevented them from making DHA out of shorter-length basic omega 3 oils (Alpha-linolenic acid like flax oil).

DHA can be obtained in the diet from cold water fish and from animal products wherein the animals grazed on grass.  Grass contains alpha-linolenic acid which is converted to DHA during digestion and then stored in animal fat (or present in dairy products).  There is no DHA in vegetable sources, meaning that you have to convert basic omega 3 oil into the longer length DHA oil.  This process appears not to work in Alzheimer’s patients.

Clearly the best strategy to guard against this problem is to take already formed DHA supplements as well as consuming dietary DHA (which is not always easy to get).

I get my Omega-3 from Nordic Naturals because their standards are above the European requirements for purity and those standards are above the US standards. Check out their website:
