چکیده:
Objective: Mini-mental state examination, a nonspecific measure of global cognitive function,
and the clock drawing test, a very concise and specific measure of cognitive function, are
among the most widely used screening tests for cognitive dysfunction. The present research
aimed to examine the correspondence between MMSE and CDT scores.
Methods: A total of 70 older adults (mean(SD) age=69.70(6.41) y) were selected by convenience
sampling method from two local health centers from the same civil servant area in Mashhad City,
Iran. They completed MMSE and CDT tests. Mann–Whitney U test and Spearman correlation
were used for analyzing the data.
Results: Results showed a significant correlation between CDT and MMSE total score. Also
the older adults’ performance on MMSE and CDT were significantly related to their level of
education and gender, but not age.
Conclusion: The correlation between the MMSE and CDT test scores was high. Although one
test cannot be replaced for the other, the CDT is a simple test that can be used for fast initial
screening of cognitive performance among the elderly.

"Although CDT is a specific indicator of executive functions, the test assesses many cognitive skills that may be involved in early stage of Alzheimer disease, such as short-term memory, spatial orientation, abstract thinking, planning, concentration, executive and visuospatial skills (Aprahamian, Martinelli, Neri, & Yassuda, 2009).

Hence, the present study of older adults evaluated the correlation between these two tests, and also the effect of three important factors; gender, age and educational level on MMSE and CDT performance.

Although the results of this study showed that the per- formance of MMSE is similar and correlated with that of CDT in a group of 70 older adults, we are uncertain about the diagnostic power of the CDT when used as the only tool for screening people with cognitive impair- ment; therefore, our findings do not imply that clinicians should merely rely on CDT in their clinical assessments."
