Background: Anemia is a risk factor for cognitive impairment as a result of the reduced delivery of oxygen to the brain from low hemoglobin (Hb) levels. In ambulatory patients even mild anemia (Hb < 12g/dL) has been associated with reductions in patients’ cognitive function. However, in hospitalized patients it is standard of care to maintain [...]

Background: Alzheimer disease (AD) is characterized by cognitive impairment including memory impairment, executive dysfunction, visuospatial impairment, and behavioral changes. Previous studies have shown that increasing level of physical activity serves as a protective factor against progression of AD. This study aims to assess the effect of long-term physical activity on cognitive function and identify whether [...]

Background: Anemia is a risk factor for cognitive impairment as a result of reduced delivery of oxygen to the brain from low hemoglobin (Hb) levels. In ambulatory patients, mild anemia (Hb 10-12g/dL) has been associated with reductions in patients’ cognitive function [1–3]. In hospitalized patients it is standard of care to maintain Hb levels far [...]
