Protect Your Memory With Vitamin B12
-- Alzheimer's disease is the seventh-leading cause of death in the
United States. This progressive and fatal brain disease destroys brain
cells, causing memory loss and problems with thinking and behavior.
Currently there is no cure, but a recent study reveals that vitamin
B12 may be effective in reducing the risk of memory loss.
"Low levels of vitamin B12 are surprisingly common in the elderly.
However, the few studies that have investigated the usefulness of
vitamin B12 supplements to reduce the risk of memory loss have had
mixed results," Babak Hooshmand, M.D., MSc, with Karolinska Institutet
in Stockholm, Sweden, was quoted as saying.
For the seven-year study, researchers took blood samples from 271
Finnish people age 65 to 79 who did not have dementia at the start of
the study. During that time, 17 people developed Alzheimer's disease.
Blood samples were tested for levels of homocysteine, an amino acid
associated with vitamin B12, and for levels of the active portion of
the vitamin, called holotranscobalamin. Too much homocysteine in the
blood has been linked to negative effects on the brain, such as
stroke. However, higher levels of vitamin B12 can lower homocysteine.
This study found that for each micromolar increase in the
concentration of homocysteine, the risk of Alzheimer's disease
increased by 18 percent, whereas each picomolar increase in
concentration of the active form of vitamin B12 reduced that risk by
two percent. The results stayed the same after taking into account
other factors, such as age, gender, education, smoking status, blood
pressure and body mass index.
