Link Proposed for Anemia and Impaired Thinking
Link Proposed for Anemia and Impaired Thinking - CME Teaching Brief® - MedPage Today: "BALTIMORE, Sept. 15 -- Mild anemia, long associated with to fatigue and weakness, may be an independent risk factor for loss of so-called executive function in older patients, researchers reported.
Community-dwelling women, ages 70 to 80, with anemia were four to five times more likely to perform poorly on executive function tests compared with those having normal hemoglobin levels, according to a study in the September issue of The Journal of the American Geriatrics Society.
Impaired executive function (ability to solve problems, plan, assess danger, track important activities) often precedes memory loss and may affect the ability to carry out daily-living activities, such as shopping, cooking, taking medications, paying bills, and walking, said Paulo Chaves, M.D., Ph.D., of Johns Hopkins here, and colleagues.
A number of studies have investigated the relationship between mild anemia and physical functioning in community-dwelling older patients, but cognition has lagged behind, he said.
Dr. Chaves and his team studied 364 high-functioning older women (mean age 73.9), participating in the Women's Health and Aging Study II, in Baltimore, from 1994 to 1996.
More than 80% of the women had a Mini-Mental State Examination score of 27 or greater, and the hemoglobin for most was in the normal range, with only 8.6% (n=30) with anemia, defined as Hb less than 12.0 g/dL"
