Carbs make you lose your mind?

Of course if this report was saying the opposite the paleo world would be criticising it because it relies on food survey questionnaires  which are notoriously dodgy.  Be that as it may, this indicates that diets higher in protein and fat fare better in preventing cognitive decline....Who knows, it is all correlation and questionnaires, but is very interesting:

Researchers tracked 1,230 people ages 70 to 89 who provided information on what they ate during the previous year. At that time, their cognitive function was evaluated by an expert panel of physicians, nurses and neuropsychologists. Of those participants, only the roughly 940 who showed no signs of cognitive impairment were asked to return for follow-up evaluations of their cognitive function. About four years into the study, 200 of those 940 were beginning to show mild cognitive impairment, problems with memory, language, thinking and judgment that are greater than normal age-related changes.
Those who reported the highest carbohydrate intake at the beginning of the study were 1.9 times likelier to develop mild cognitive impairment than those with the lowest intake of carbohydrates. Participants with the highest sugar intake were 1.5 times likelier to experience mild cognitive impairment than those with the lowest levels. 
But those whose diets were highest in fat — compared to the lowest — were 42 percent less likely to face cognitive impairment, and those who had the highest intake of protein had a reduced risk of 21 percent. 
When total fat and protein intake were taken into account, people with the highest carbohydrate intake were 3.6 times likelier to develop mild cognitive impairment.

The study is discussed here:

As usual, correlation is not causation, etc.

Not surprising really, I guess that could explain why fat people are addicted to junk food and don't really care.
