Prevention of Dementia with ω3 Fatty Acids-Up to Date

Abstract

It is well known that ω3 fatty acids are deeply involved in the cardiovascular system, lipid metabolism system, and maintenance of brain function. Omega-3 fatty acids, especially docosahexaenoic acid is abundant in the brain and plays an important role in maintaining brain functions. Although there are some negative opinions, the intake of ω3 fatty acids can be suppressed or delayed the progression of cognitive impairment, and further may help to prevent the onset of dementia not only for elderly people with age-related cognitive decline and mild cognitive impairment but also for patients with pre-clinical dementia by considering the time to start and the form of intake.
