Anemia Body And The Mind

Anemia Body And The Mind
For elderly adults, anemia's trademark loss of oxygen-toting red blood cells has long been associated with fatigue, muscle weakness and other physical ailments. Now scientists at Johns Hopkins have found a relationship between anemia and impaired thinking, too.

"Our work supports the notion that mild anemia may be an independent risk factor for so-called executive-function impairment in elderly adults," says Paulo Chaves, M.D., P.h.D., an assistant professor at The Johns Hopkins University School of Medicine and the lead author of the study. "If further studies confirm that's true, this could mean that correction of anemia in these patients might offer a chance to prevent such a cognitive decline".

Reporting on the research in the recent issue of The Journal of the American Geriatrics Society, the Hopkins researchers went looking for such an effect because prior studies showed that age-related declines in the brain's so-called executive function - problem solving, planning, assessing dangers, following up on important activities - lead to declines in self-sufficiency.

"Executive function impairment, which happens often before memory loss occurs, may happen early on in the process of becoming unable to carry on with instrumental day-to-day living activities, such as shopping, cooking, taking medications, paying bills, walking, etc.," says Chaves.

Chaves and his team gave three psychological tests usually used to evaluate executive function to 364 women, all between 70 and 80 years old, who were living in Baltimore, Md. Approximately 10 percent had anemia, which was of mild intensity.

Some 15 percent of those with the worst results on all three of the tests were anemic, in comparison to only 3 percent who scored best. Those with anemia were four to five times more likely to perform worst on the executive function tests, in comparison to those with normal blood hemoglobin, after taking into account the effect of other factors that affect cognition, such as age, education and existing diseases.

"These preliminary results don't prove that anemia causes impaired executive function, nor indicate that therapy of anemia would necessarily lead to better executive function," says Chaves. "However, they are compelling enough to serve as a roadmap for continued research." .

How anemia could affect thinking remains to be determined. It could be because it chronically diminishes the supply of oxygen to the brain. Another view proposes that the fatigue accompanying anemia leads to inactivity and the loss of aerobic-fitness benefits to the prefrontal cortex.
