NBC News (4/8, Sullivan) reports research found that “regular exercise and about seven hours of sleep a night could protect brain health in the long term,” while “long bouts of sedentary behavior may increase dementia risk.” Simple lifestyle changes may “reduce a person’s risk of late-onset dementia by as much as 25%, according to the study.” A person’s overall Alzheimer’s disease risk is about 11%, but “with the suggested changes in lifestyle, the average person’s risk decreases to about 8%.” The study found that “breaking up longer periods of sitting had the greatest effect.” The findings were published in PLOS One.
