A recent review of studies investigating cognitive decline in later life has drawn attention to the fact that many dementia patients suffer from a lack of vitamin B12 and folic acid.

In a paper published by Ross Andel and Tiffany Hughes of the University of Florida's School of Aging Studies, strong evidence is presented that points to a connection between mental deterioration and low levels of these important nutrients.

It is recommended that people make a point of including vitamin B12 in their diets by increasing consumption of foods such as meat, poultry, fish, eggs, and dairy products. Supplementation is also very helpful, especially for vegetarians, and those over 50.
