Abstract :
The aim of this study was to investigate the predictive role of working memory capacity and executive functions (shifting, inhibition and updating) for Alzheimer›s predisposition. We selected 148 elderly people (75 male and 73 female) from Qazvin with available sampling procedure and they completed Mini Mental State Examination ( Alzheimer›s predisposition), the Digit Span in backward format Task (workingmemory capacity), Stroop (inhibition), Set- Switching Task (shifting) and Keep Track Task (updating). Data analysis was accomplished using analysis showed working memory and executive function totally predicted considerable amount (61 percents) of Alzheimer›s predisposition. At the end data were discussed in light of theory and practice.
