More than 6% of Americans ages 70 to 89 develop mild cognitive impairment (MCI) every year, and the condition appears to affect men more than women.
Mild cognitive impairment (MCI) is a condition that affects thinking and memory skills; an estimated 5 to 10% of those with MCI subsequently develop dementia. Rosebud O. Roberts, from the Mayo Clinic (Minnesota, USA), and colleagues report that more than 6% of Americans ages 70 to 89 develop MCI every year. Also, the condition appears to affect men and those who only have a high school education more than women and those who have completed some higher education. Noting “Differences in incidence rates,” the study authors warn that: “The incidence rates for [mild cognitive impairment] are substantial.”
