The present study aims to adapt and to standardize the MDRS in the Moroccan population. The Moroccan Dementia Rating Scale was adapted in Arabic and was administered to 192 younger and older individuals without cognitive deficits (96 men and 96 women) whose ages ranged from 18 to 85 years old. To investigate the impact of age and schooling, participants were classified into three levels of education, and three age categories. The results show that age and level of education strongly influenced the performance of an average of 124/144 of the MDRS subjects who were tested.
