MedPage Today (5/13, George) reports, “More time spent sitting or lying down was linked with neurodegeneration and worse cognitive scores in older adults, even among people who were physically active, a 7-year study showed.” Researchers observed that “in cross-sectional models, greater sedentary time was tied to a smaller Alzheimer’s disease-imaging MRI signature and worse episodic memory scores.” They added that “in longitudinal analyses, more sedentary time was associated with faster hippocampal volume shrinkage, and declines in naming scores and processing speed scores.” Investigators concluded, “These findings suggest that above and beyond physical activity level, more sedentary behavior is still worse for brain health and cognition over time.” The study was published in Alzheimer’s & Dementia.
