In this study 23 older adults with mild cognitive impairment were assigned to either a (i) high carbohydrate or (ii) very low carbohydrate diet for 6 weeks.
The study found after 6 weeks:
(a) Improved verbal memory performance for the low carbohydrate subjects.(b) Reductions in weight in the low carbohydrate subjects.
(c) Change in calorie intake, insulin level, and weight were not correlated with memory performance for both groups.
(d) Higher ketone levels were positively correlated with better memory performance.
To conclude: In older adults with increased risk for Alzheimer's disease, these findings indicate that very low carbohydrate consumption, even in the short term, can improve their memory function.
