Possibly: If the person has a reversible dementia related to low levels of vitamin b12, then replacing vitamin B12 could help. Together with folate, (folic acid) B12 has also been implicated in some cases of depression. www.ncbi.nlm.nih.gov/pubmed/15671130.

Not usually: If you have a B12 deficiency it can cause dementia and depression but this uncommon in the american diet. If one doesn't eat much meat it can be worth checking.
