English: PET scan of a human brain with Alzheimer’s disease

“Quiet” mental retardation may be adding to a kind of dementia or stroke. Exactly what takes place is that the brain deals with “quiet brain infarcts” when little areas of brain tissue pass away from an inadequate supply of blood. This subtle form of brain damage is linked to dementia or stroke. Most of the time there are no symptoms and can only be detected by an MRI.

A study used data from 3,660 clients in the Cardiovascular Wellness research study of individuals 65 and older who underwent at least one brain scan of which 2,313 individuals had two scans five years apart. They all completed food frequency surveys.

The outcomes showed that those who consumed the most tuna and other non-fried fish had a 26 % minimized risk of quiet infarcts compared with those consuming the least, less than one serving a month. For each added portions of tuna or other baked/broiled fish the danger of infarct fell by 7 %. Those eating at least three portions of fish each week also scored 10.6 % much better on a test of white matter in the brain. No protective effect was seen from fried fish like fish sticks made from pollack or cod. The authors hypothesized that the greater omega-3 content of the safety fish such as tuna was included as pollack or cod is usually reduced in omega-3 fatty acids.

EPA and DHA (eicosapentaenoic and docosohexaenoic acids), respectively, are 2 omega-3 fatty acids that have actually been received priceless researches to be linked to lower risks of dementia and Alzheimer’s illness. The authors concluded: “Our findings recommend that the prevention of subclinical infarcts and white matter anomalies could be one system by which fish or omega-3 fatty acid usage may minimize the development of these debilitating conditions”. This research study was published in the journal Neurology, August 5, 2008.
