Abstract:
Objective:To assess clinical validity of the Chinese version of Mattis Dementia Rating Scale (DRS) in differentiating dementia of Alzheimer type (AD). Methods:Administered the DRS, mini-mental state examination (MMSE) and clinical dementia rating(CDR) to 61 outpatients with AD and 104 healthy elderly subjects in Shanghai.Results:There was significant correlation between DRS and the total score,and DRS and MMSE.DRS of the AD group had significant correlation with CDR.Its significant correlation with CDR suggested satisfactory concurrent validity of the scale. The optimal DRS cutoff score for AD according to education level revealed a sensitivity of 85%～94% and a specificity of 90%～94%.Conclusion:The DRS is a clinically valid test for the detection of AD and its severity of cognitive impairment.
