This thread caught my attn, I take EPA/DHA caps
this is article on other benefits.
By Greg Arnold, DC, CSCS, November 14, 2006, abstracted from “Dietary supplementation of arachidonic and docosahexaenoic acids improves cognitive dysfunction” in the November 2006 issue of Neuroscience Research
When research has looked at the cognitive decline that frequently occurs with aging, a common theme is the accompanying decline of two fats in the brain called arachidonic acid (ARA) and docosahexaenoic acid (DHA).1 This cognitive decline is well known to be associated not only with aging or Alzheimer's disease (AD), but also with various organic brain diseases, such as cerebral hemorrhage and traumatic brain injuries.
In addition to being associated with learning-memory and vision,2 DHA is also useful for the prevention of brain damage by helping prevent clotting.3 Both DHA and ARA decline as we age.4
Now a new study5 has found that supplementing DHA and ARA into the diet may help slow cognitive decline.
In the study, 21 patients classified as having mild cognitive dysfunction, 10 patients with organic brain lesions and 8 patients with AD completed cognitive tests before they started taking 240 mg per day of ARA/DHA or 240 mg per day of olive oil (placebo). They then completed cognitive tests 90 days after the study began. The cognitive tests administered were called RBANS6 and precisely estimates five cognitive domains: short-term memory, visual/constructional ability, language, attention, and long-term memory.
At the end of the study, the supplement group showed a “significant improvement” of short-term memory and attention score. In addition, patients with organic brain lesions in the supplement group showed “a significant improvement” of both long-term and short-term memory. No significant improvements were seen in either of the AD groups or the other placebo groups.
For the researchers, this study suggests “that ARA and DHA supplementation can improve the cognitive dysfunction due to organic brain damages or aging.”
