According to the researchers from the University of Santiago de Compostela, who focused on level of vocabulary as it is considered an indicator of crystallised intelligence (the use of previously acquired intellectual skills), found that a greater prevalence of mild cognitive impairment in participants who achieved a lower vocabulary level score.
The researchers said that the findings led them to the conclusion that a higher level of vocabulary, as a measure of cognitive reserve, can protect against cognitive impairment.
