“…The mean TYM-I scores in our HC and MCI samples were lower than those in the control and MCI samples evaluated in Brown’s et al original studies ( Brown et al, 2009 ; Brown J. et al, 2019 ). However, results are inconsistent among investigations from different countries and several studies reported average scores in line with those of the present study in both controls ( Hancock and Larner, 2011 ; Abd-Al-Atty et al, 2012 ; van Schalkwyk et al, 2012 ; Muñoz-Neira et al, 2014 ; Postel-Vinay et al, 2014 ; Iatraki et al, 2014 , 2017 ; Kolozsvári et al, 2017 ; van de Zande et al, 2017 ; Li et al, 2018 ) and MCI patients ( Hancock and Larner, 2011 ; Muñoz-Neira et al, 2014 ; van de Zande et al, 2017 ). Whether this heterogeneity might be partly attributed to a difference in educational levels should be accurately addressed in future studies.…”
