(Reuters Health) - Dietary supplementation with omega-3 fatty acids for 6 months appears to be of little benefit in patients with mild to moderateAlzheimer's disease (AD), according to results of a study conducted in Sweden.However, a second look at the data suggests that omego-3 fatty acids may protect cognitive function in patients with very mild, early stage AD.Studies have shown that a diet rich in omega-3 fatty acids, as found in fish oil, reduces the risk of AD. Furthermore, animal studies have shown that the two predominant omega-3 fatty acids in fish oil, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), preserve cognitive function.To evaluate the effect of DHA/EPA on patients already diagnosed with AD, investigators led by Dr. Jan Palmblad, from Karolinska University Hospital Huddinge in Stockholm, randomly recruited 174 patients with mild to moderate AD.(Read entire article)
Diets high in the omega-3 fatty acids found in fish such as mackerel, sardines and salmon might ward off Alzheimer’s disease.
That’s what researchers report in the March 23 online issue of the Journal of Neuroscience.
The study was conducted in mice, but senior author Greg M. Cole said it probably applies to humans as well.
“Our data show it works in animals,” said Cole, associate director of the Alzheimer’s Disease Research Center at the UCLA David Geffen School of Medicine. “If this works in people, it’s clearly going to be one of the ways we protect ourselves from Alzheimer’s disease.” (Read entire article)
