详细说明
The age-related degradation of cognitive functions even to the point of neurodegenerative disorders such as Alzheimer's disease are a growing public-health concern with devastating effects.
Referring to animal data, empirical studies, and pilot human trials, dietary modification (caloric restriction, omega-3 fatty acids and resveratrol) should improve cognitive functions such as learning and memory. To test this hypothesis, the researchers study general brain functions in elderly subjects (50-80 years old) with mild cognitive impairment.
