Title: A Randomized Double-Blind Placebo-Controlled Trial Of The Effects Of Docosahexaenoic Acid (DHA) In Slowing The Progression Of Alzheimer's Disease
Brief Summary: The purpose of this study is to determine whether chronic DHA (Docosahexaenoic Acid) supplementation slows the progression of cognitive and functional decline in mild to moderate Alzheimer's disease (AD).

A: Inclusion Criteria:

1. Male or female subject, age 17 or older; country-specific age limitations will be followed

3. In remission for at least 3 months, but no longer than 12 months; remission being defined as meeting both of the two conditions: (1) clinically in remission with a CDAI of less than 150 and (2) off steroids and/or immunosuppressants for at least 3 months, if remission had been induced with such medications

Exclusion Criteria:

1. Intolerance of omega-3 fatty acids or known allergy to fish or fish products

3. Current or past history of diabetes or hyperlipidemia requiring specific drug therapy (see below).
4. Current use of a weight loss medicine, such as a 'fat-burner' or similar agent
5. Alcohol consumption \> 30 g/day, currently or for more than 3 consecutive months within 5 years.
