This article summarizing recent research published in the Journal of Alzheimer's Disease says seniors who limit carb consumption have a lower risk of developing dementia.
Quoting the article "A Mayo Clinic study says that elderly people have a lower risk of cognitive impairment if they consume a diet high in fat and protein as opposed to a diet with lots of carbs and sugar. Glucose levels might play a role in the development of beta amyloid plaques, proteins toxic to brain health found in the brains of people with Alzheimer's."
Also from the article "Those whose diets were highest in fat (nuts, healthy oils) were 42% less likely to get cognitive impairment, while those who had the highest intake of protein (chicken, meat, fish) had a reduced risk of 21%."
There has been speculation that insulin resistance, which is a hallmark of T2, can also have an effect on the brains metabolism, perhaps influencing the development of dementia.
Should this study influence recommendations for diet in T2's? Will this cause you to rethink your own carb consumption?
