High Homocysteine Related to Reduced Memory in Seniors

Researchers at Boston University have found that having high blood levels of homocysteine, an amino acid formed during metabolism, is related to a greater decline in cognitive function after the age of sixty than that experienced by individuals whose levels of homocysteine are lower. No such relationship between cognitive function and homocysteine levels was observed in younger people.

In prior studies, homocysteine has been associated with an increased risk of cardiovascular disease among other adverse health conditions. In this study, researchers stated: "Managing homocysteine levels by taking vitamins B12, B6, folate and betaine (trimethylglyceine TMG) could offer a side-effect-free way to prevent difficulties in memory and recall later in life."
