The prevalence of vitamin B 12 deficiency increased substantially in the elderly, where 31% of the elderly had vitamin B 12 levels below 130 pmol/L. In the most recent NDNS survey conducted between 2008 and 2011, serum vitamin B 12 was measured in 549 adults. [ 162 ]
Symptoms of low B12 levels can also mimic signs of dementia. "I check a B12 level in all the patients I see with memory loss," says Clifford Segil, DO, neurologist at Providence Saint John’s ...
Blood tests showed that their B12 levels averaged 414.8 pmol/L, while the recommended minimum level in the U.S. is just 148 pmol/L. Drugs That Reduce Dementia Risk — And Others That Increase It
Vitamin B 12 deficiency has been observed in between 40% and 80% of the vegetarian population who do not also take a vitamin B 12 supplement or consume vitamin-fortified food. [36] In Hong Kong and India, vitamin B 12 deficiency has been found in roughly 80% of the vegan population.
Vitamin B 12 deficiency prevents the 5-methyltetrahydrofolate (5-MTHF) form of folate from being converted into THF due to the "methyl trap". [18] This disrupts the folate pathway and leads to an increase in homocysteine which damages cells (for example, damage to endothelial cells can result in increased risk of thrombosis). [citation needed]
Over time, a deficiency of B12 can cause problems with balance, confusion, depression, poor memory and possibly dementia, and it can even cause permanent damage to the nervous system, Somers says.
Serum vitamin B 12 is a medical laboratory test that measure vitamin B 12 only in the blood binding to both transcobalamins. [1] Most of the time, 80–94% of vitamin B 12 in the blood binds to haptocorrin , while only 6–20% is binds to transcobalamin ll. [ 2 ] Only transcobalamin ll is "active" and can be used by the body. [ 1 ]
Deficiency can also result from rare genetic factors, such as mutations in the MTHFR gene that lead to compromised folate metabolism. [33] [34] Cerebral folate deficiency is a rare condition in which concentrations of folate are low in the brain despite being normal in the blood. [35] Vitamin B 12 deficiency: Anemia, neurological and digestive ...
