Homocysteine & Alzheimer’s Disease (2002)

A total of 1092 subjects without dementia (667 women and 425 men; average age, 76 years) were followed for an average of 8 years. Their homocysteine levels were monitored and it was noted which of those went onto develop dementia and Alzheimer’s. The authors concluded that an increased level of homocysteine in the blood is a “strong, independent risk factor for the development of dementia and Alzheimer’s Disease”. There was a doubling of risk for Alzheimer’s with a homocysteine level greater than 14mmol/l.
