In a major breakthrough in their understanding of the debilitating dementia, the scientists said they had found that the omega-3 docosahexaenoic acid (DHA) increased the production of LR11, a protein which is lacking in people with Alzheimers disease and is known to destroy another protein that forms the plaques associated with the condition.
Alzheimers is a neurodegenerative disease which causes memory loss, dementia and personality changes. Until now, researchers have speculated that fish oil may have an anti-Alzheimers effect but have had little evidence and have been unsure why it might be protective.
