Method: In a descriptiveanalytical study, patients presenting to Noor Hospital Neuropsychiatric Clinic and the Neurology Department of Ayatollah Kashani Hospital in Isfahan in autumn 08 were evaluated and 33 individuals with dementia were selected using convenience sampling. The Mini-Mental State Examination (MMSE) and NUCOG were administered to the patients. Data were analyzed using descriptive statistics, Pearson correlation coefficient, Chi test, and Cronbach s alpha. Results: Content validity of NUCOG was confirmed. The internal consistency of the NUCOG by Cronbach's alpha was The convergent validity of the MMSE and the NUCOG was 0.9 (p<0.00).
