The long-term study was conducted by the National Institute of Health (NIH) with analysis of the data led by Dr. Rebecca Gottesman from Johns Hopkins University.
Over a 25-year period, researchers tracked the cardiovascular health and memory of 15,744 participants by measuring their cardiovascular health and cognitive abilities five times. All participants were located within four states of the United States and aged 45 to 64 at the start of the study.
During the 25-year period, 10 percent of participants were diagnosed with dementia. Dr. Gottesman’s team compared the cognitive and cardiovascular health of these participants with the others in the study.
