Omega-3 Fatty Acids Expected to Combat Dementia Risks

Recent studies indicate that omega-3 fatty acids, found in oily fish, nuts, and seeds, may offer protective benefits against motor neurone disease (MND) and certain forms of dementia, including frontotemporal dementia. Research led by the UK Dementia Research Institute revealed that fruit flies with a genetic mutation related to these conditions showed improved survival rates when supplemented with omega-3s, particularly alpha-linoleic acid. The study also highlighted that levels of polyunsaturated fatty acids were significantly lower in brain cells of individuals with MND and dementia. Additionally, experts suggest that correcting age-related declines in brain DHA levels could slow neurodegenerative processes, emphasizing dietary sources over supplements for optimal effectiveness. Current evidence points to the greater efficacy of lysophosphatidylcholine-bound DHA from fish compared to typical fish oil supplements. This growing body of research underscores the potential of dietary omega-3s in enhancing brain health and longevity.
