Genetic Variation May Reduce Alzheimer’s Risk1
Genetic Variation May Reduce Alzheimer’s Risk
Adults with a genetic variation enabling them to express higher levels of fetal hemoglobin may have a reduced risk of Alzheimer’s disease, researchers say.A study of 209 families with at least two siblings with Alzheimer’s and one unaffected sibling showed that those with this genetic variation are less likely to have the disease, researchers say in Neurobiology of Aging. An estimated 25 percent of the population has the XmnI polymorphism. [click link for full article]
Higher Folate Levels Linked To Reduced Risk For Alzheimer’s Disease
Individuals who take in higher levels of the nutrient folate through both diet and supplements may have a reduced risk of developing Alzheimer’s disease, according to a report in the January issue of Archives of Neurology, one of the JAMA/Archives journals.By the year 2047, the prevalence of Alzheimer’s disease is expected to quadruple, according to background information in the article.

Cognitive Performance May Be Improved By Folic Acid Supplementation
Folic acid supplementation may substantially improve cognitive function for older adults, according to an Article in the Lancet.Cognitive function declines with age, especially cognitive domains related to information processing speed and memory. Such changes in cognitive function have been linked to risk of dementia in old age. [click link for full article]

New Gene Uncovered For Late-Onset Alzheimer’s
An international team of researchers, led by Columbia University Medical Center, Boston University School of Medicine and the University of Toronto, has uncovered a major new gene SORL1 implicated in late onset Alzheimer’s disease. Replicated in four distinct ethnic groups, SORL1 is only the second genetic variant for late onset Alzheimer’s, the type of Alzheimer’s found in 90 percent of people with this devastating disease. ApoE4, the first, was identified in 1993. [click link for full article]
Alzheimer’s vaccine via a skin patch shows promise
A new study promises to make an Alzheimer’s vaccine a reality sometime in future after it was found that skin patches were successful in clearing the brain plaques, which are the standout feature in Alzheimer’s …
