LACK OF B12 AND MEMORY LOSS

Gabe Mirkin, M.D.

Lack of B12 is a common cause of senility. An article from Austria 
showed that many doctors miss the correct diagnosis of B12 
deficiency because people with a deficiency often have normal blood 
levels of that vitamin. 

Many people suffer from vitamin B12 deficiency because they have low 
blood levels of homotranscobalamine II, the protein that transprts 
B12 into the mitochondria where it acts. So you can have normal 
levels of B12 and still be deficient. When you body lacks B12, your 
red blood cells do not mature properly and are much larger than 
normal, and an amino acid called homocysteine accumulates in your 
bloodstream. Doctors in Austria showed that much more dependable 
tests for B12 deficiency are MCV, a test that measures the size of 
red blood cells; and blood levels of homocysteine.
