Fish Oil & Cognitive Decline (2007)
This study investigated fish oil & cognitive decline. 210 men aged 70 to 89 years old were followed for 5 years. There was a significant association between intake of fish oil (EPA and DHA) from diet and rate of cognitive decline, with those taking in the most fish oil from oily fish showing the least decline. 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.
