Summary: Researchers studied over 1,500 late middle aged adults without dementia to see how the levels of omega-3s in their blood are related to signs of future dementia. Adults with the lowest amount of the fish-based omega-3, DHA, in their blood had smaller brain volumes and poorer performance in tests of visual memory; abstract thinking; and planning, organization, and carrying out of tasks than adults with higher DHA levels.
