Recent studies highlight the potential role of omega-3 fatty acids in protecting brain health, especially among older adults. These essential fats, found in fatty fish like salmon, offer benefits for heart health, inflammation, and brain function.

Breakthroughs in Alzheimer’s disease research offer hope for the successful treatment – and elimination – of the disease. This was the finding of New Scientist journalist Graham Lawton, who reviewed the history and status of research on dementia and Alzheimer’s disease.
