B12 May Lower Your Risk For Alzheimer's Disease

A Finnish study showed a group of elderly subjects followed up for 7 years with elevated baseline serum homocysteine levels were independently associated with an increased risk of developing Alzheimer's disease. Several studies linked elevated homocysteine levels with an increased risk for stroke, cognitive decline, and dementia, including Alzheimer's. Homocysteine can directly promote cerebrovascular disease and neuronal injury through a variety of mechanisms. Many individuals with high homocysteine levels also have low B12 levels. Therefore, B12 may also play a role in Alzheimer's disease.
