Anemia in adults 60 and older linked to 66% higher dementia risk

A new study has found that the effects of anemia—a condition caused by a lack of hemoglobin needed to carry oxygen to organs and tissues—may stretch beyond fatigue, shortness of breath, and pale skin. They reach into the brain, raising the risk of dementia and linking to higher levels of biomarkers associated with Alzheimer's disease (AD) and neurodegeneration.
