The complex relationship between omega-3 fatty acids and neurodegenerative diseases

by Sayuri Miyamoto

Docosahexaenoic acid (DHA) is an omega-3 fatty acid that is well known by its health-promoting effects. Being highly abundant in the brain, DHA displays essential role in neurological and visual development in infants. In adults, the decline of DHA content in brain has been associated to cognitive impairment and the use of omega-3 supplements have been thought to exert neuroprotective effects. Indeed, some studies indicated that consuming DHA would be beneficial for the prevention of cognitive disorders such as Alzheimer’s disease [1].
