B12 Deficiency and Dementia
Some interesting research has come out of the University of Waterloo in Canada on the use of B12 for dementia
A high proportion of older adults entering long-term care homes in Ontario are B12 deficient, with more developing deficiencies over the course of their first year in residence, according to research from the University of Waterloo. There is a connection between B12 deficiency and several serious health conditions.
Researchers found that almost 14 per cent of study participants were B12 deficient at the time of admission to a long-term care home, while another 38 per cent had only slightly better levels. Over the course of one year, an additional four per cent developed B12 deficiencies. However, those receiving supplements had better B12 levels.
The study, conducted in partnership with the Schlegel-University of Waterloo Research Institute for Aging (RIA) and published in Applied Physiology, Nutrition, and Metabolism, suggests a simple, yearly blood test could be the key to eliminating B12 deficiencies among elderly living in long-term care homes.
“The negative effects of a B12 deficiency are considerable,” said Heather Keller, a professor of kinesiology at Waterloo and Schlegel Research Chair in Nutrition and Aging. “This is of particular importance in the context of our aging population with more Canadians requiring long-term care.”
Untreated B12 deficiency will eventually lead to anaemia and neurologic complications such as unsteady gait and paralysis. Low levels of the vitamin have been associated with depression and dementia, increased confusion, lethargy and even osteoporosis.
“In spending time in long-term care homes, you often see depression and loneliness. This is why we need to do everything in our power to enhance quality of life and quality of care in this setting,” said Kaylen Pfisterer, lead author on the paper and assistant research coordinator at the RIA. “Screening for B12 deficiency is a first step to targeting B12 treatment to those who may benefit most.”
B12 deficiency is highly preventable and easily treatable with improved food choice and supplements. Foods rich in B12 include meat and dairy products or choose a high quality B12 natural health supplement.
