Good News on Fish Oils Just Keeps Coming!
In a study of 2,000 people aged 50 to 65 years old, those with the highest levels of fish oils had the least decline in verbal fluency. This was particularly true for those with high blood pressure and high cholesterol or fats in the blood.

In another study, 210 men aged 70 to 89 years old were followed for 5 years. There was a very strong association between intake of fish oil from diet and rate of cognitive decline, with those taking in the most fish oil from oily fish showing the least decline in cognitive function. The measure of decline used the Mini-Mental State Exam (MMSE) which includes questions on orientation to time and place, registration, attention and calculation, recall, language, and visual construction.

In a study using mice which had been genetically altered to display characteristics of Alzheimer's Disease, DHA (from fish oil) reduced the accumulation of beta-amyloid and tau in their brains. Higher levels of beta-amyloid and tau in the brain is a sign of progression in Alzheimer's Disease, suggesting that fish oils may not only be useful in prevention but also in slowing the progress of the disease.

A new study confirms that children taking a combination of omega-3 fish oil and omega-6 evening primrose oil for 15 or 30 weeks, versus placebo, have major improvements in ADHD symptoms, as measured on the Conner's scale, (which is what was measured in the Food for the Brain Cricket Green project.) The treatment effects for those taking omega-3 and omega-6 with a multivitamin were comparable with average treatment effects of stimulant medication such as Ritalin, according to parent ratings of behaviour.
