At the beginning of the study, each person is given a series of tests to measure their cognition, followed by a blood test to determine the levels of two omega-3 fatty acids commonly found in oily fish: DHA and EPA.
"We found that for people with a level of Omega-3 is low, supplements of vitamin B have little or no effect. But for those with levels of omega-3, vitamin B is very effective in preventing cognitive decline compared with placebo," explained Dr. Abderrahim Oulhaj of Oxford.
"These results complement our previous findings that vitamin B slows the rate of brain atrophy in MCI only in those with higher levels of omega-3 is good," he added in a paper published in the Journal of Alzheimer's.
The team also found that blood levels of DHA may be more important than the level EPA, although they caution that more research should be conducted to determine whether this is true.
The next stage is to see whether it provides a combination of B vitamins and Omega-3 supplements can slow the conversion from MCI to Alzheimer's disease, the authors note.
