I found that a buildup of homocysteine in the brain can lead to negative cognitive effects. It is metabolized using vitamins B6 and B12.

This is an interesting question, but "mental performance" is much too broad and vague a measure to be answered meaningfully, at least for me. Recommendations:
1) Add some background literature to provide context on what kind of performance you're thinking of.
2) Restrict the scope of the question to a (few) specific measure(s). Something like "What is the association between common nutritional deficiencies and working memory?" would be more amenable to answering.

What are the common nutritional deficiencies in western countries related to reduced mental performance ? I've heard about omega 3, folid acid, and vitamin D deficiencies, the last two are now reduced due to food suplementation in some countries.
