There is no doubt that the term mild cognitive impairment (MCI) has become popular in the last decades (Flicker et al., 1991; Petersen et al., 1997). A superficial quantification of the publications that include said term in the title in the Web of Science yields 9,334 citations, including 6,553 articles, 667 reviews, 187 editorials, 37 books, and 249 patents.
