European researchers have also shown that giving B12 to people deficient in the vitamin helped protect many of the areas of the brain damaged by Alzheimer’s disease. In a two-year study at the University of Oxford of 270 people older than 70 with mild cognitive impairment and low B12 levels, Dr. Helga Refsum, a professor of nutrition at the University of Oslo, found reduced cerebral atrophy in those treated with high doses of the vitamin.
“A B12 vitamin deficiency as a cause of cognitive issues is more common than we think, especially among the elderly who live alone and don’t eat properly,” Dr. Rajarethinam said.
CerefolinNAC Therapy of Hyperhomocysteinemia Delays Cortical and White Matter Atrophy in Alzheimer’s Disease and Cerebrovascular Disease
A nutritional supplement (L-methylfolate, methylcobalamin, and N-acetyl-cysteine) for hyperhomocysteinemia (HHcy) in patients with Alzheimer’s disease (AD) or cognitive impairment due to cerebrovascular disease (CVD) slowed regional brain atrophy. The nutritional supplement was associated with significantly slowed hippocampal and cortical atrophy rates in patients with Alzheimer’s disease, and related disorders, with hyperhomocysteinemia, and forebrain parenchymal atrophy rates in CVD patients with hyperhomocysteinemia.
