High DHA Levels Linked to Lower Dementia Risk

24 01 2007

Individuals with higher levels of docosahexaenoic acid (DHA) have a significantly lower risk of developing dementia and Alzheimer’s disease (AD), a new study suggests.

Researchers found individuals with the highest DHA levels had a 47% reduction in all-cause dementia and a 39% lower risk of developing AD.

DHA is a omega-3 polyunsaturated fatty acid specially found in fish with high fat content.

The investigators also note that future research should focus on determining whether the combination of dietary supplementation with DHA can prevent further mental deterioration in patients with established dementia.

The article appears in the journal Archives of Neurology.
