Objectives : The present study was carried out with the
aim of assessing the psychometric properties of “Neuro-
psychiatry Unit Cognitive Assessment Tool” (NUCOG)
in patients with dementia. Method : In a descriptive-
analytical study, patients presenting to Noor Hospital
Neuropsychiatric Clinic and the Neurology Department
of Ayatollah Kashani Hospital in Isfahan in autumn 2008
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
2
test, and
Cronbach’s alpha. Results : Content validity of NUCOG
was confirmed. The internal consistency of the NUCOG
by Cronbach's alpha was 0.919. The convergent validity
of the MMSE and the NUCOG was 0.922 (p<0.001).
There was no significant correlation between age and
