October 24/Washington/Voice of America News -- A new study says deficiencies of Vitamin B12 might be responsible for declining brain function in older adults. Although people normally get plenty of B12 from fish, meat and dairy products, as well as fortified cereals and supplements, their ability to absorb the essential nutrient can be blocked by a number of factors.
Those include excessive alcohol consumption, anemia and various digestive-system disorders. Health experts say regular screening and heightened public awareness can help avoid those potentially brain-wasting deficits.
