Abstract
Background: Increasing number of people with diabetes make it the greatest world-wide epidemy which indicates importance of education in physical and mental health of the patients. Since researches report different results about cognition status of diabetic patients, this study was conducted to determine and compare cognitive status in older people with and without type 2 diabetes.
Methods: In this case- control study 80 patients with type 2 diabetes mellitus compare with 80 persons without diabetes. Cases were selected from the patients refer to diabetes outpatient clinic and control group were patients referred to other clinics. Instruments were questionnaire for gathering demographic data, glucometer, DSM-IR-TR questionnaire, FBS for control group and TSH - T4- HbA1c for cases..
Results: The mean scores of MMSE were 23.3 and 26.8 in case and control group respectively. Difference between two groups was significant in MMSE scores (P<0.01), furthermore between men and women of two groups (P<0.01 for both). No significant difference of MMSE scores between men and women in case group was seen (P=0.45). There was negative association between MMSE scores and age also duration of illness according to the results.
Conclusion: Elderly diabetic patients encounter some cognitive impairment which is exacerbated with increasing age.

Abstract
Background: One of the common problems of the elderly, which increase of its prevalence with aging is the dementia and the cognitive impairment. We can help the involved patients to have a better quality of life with early diagnosis of the cognitive impairment. The aim of this study was an assessment of the validity and reliability of the Persian version of the abbreviated mental test (AMT) among the older people in a nursing home setting.
Methods: 176 eligible elderly people aged ≥ 60 years living in KahrizakCharity Foundation (KCF), were selected randomly based on medical record number. Demographic information and past medical history of the participants were collected. Geriatric depression scale 15 (GDS-15), global deterioration scale (GDS) forms and also the Persian version of the abbreviated mental test (AMT) were administered. The participants were assigned to two groups the normal and impaired cognitive groups, based on DSM-IV diagnostic criteria. The GDS cut-points were used for assessment of validity, sensitivity and specificity of the Persian version of AMT.
Results: The mean age of the participants was 77.30 (7.94) years. The Persian version of AMT had good discriminated validity in diagnosis of normal and impaired cognitive participants (7.35 ± 2.33 and 5.99 ± 2.29, P < 0.01 respectively) and at cut-point AMT< 8,(based on GDS cut-point) it had a sensitivity and specificity 92.15 % and 81.50% respectively. The sensitivity and specificity based on theism IVcriteriawere 64.9% and 64.0% at cut-off point equal to 7, respectively. The internal consistency of the Persian version of AMT was acceptable (Cronbach’salpha coefficient =0. 76). As well as the external reliability (intra-rater) of this instrument was good inter-class correlation coefficient (ICC) = 0.89)
Conclusion: The Persian version of the AMT has appropriate validity and reliability in Iranian older people.

Abstract
Background: Although several tools for evaluating and screening of cognitive status have been introduced, most of them are not applicable in Iranian elderly population because of cultural differences and high illiteracy rate. This study is report of "Brief Cognitive Assessment Tool"(BCAT) was developed as a cognitive status-evaluating test and reported psychometric characteristics.
Methods: the BCAT tool includes memory assessment using three words recall test with a rating similar to Mini-Cog and the functional status including "ability to dress", "ability to use the phone," " ability to manage own medications", among both two sexes and financial management capabilities in men and ability to prepare food in women. Functional rating is different in educated and non-educated people. Diagnosis of dementia is considered, when memory impairment is accompanied by the dysfunction. Eighty-six residents of a nursing home (41 men and 45 women) among who had inclusion and no had exclusion criteria also consent to participate were randomly enrolled. Concurrent validity was shown as correlation coefficient between the BCAT categorization and score of mini meAntal state examination (MMSE). Criterion validity, sensitivity and specificity of BCAT were evaluated based on global deterioration scale (GDS). Reliability of two raters results within two weeks was indicated by Kappa coefficient.
Results: The sensitivity and specificity and accuracy rate of the BCAT based the GDS was 88.6%, 82.6%, and 84.9%, respectively. The correlation between the MMSE score and results of the BCAT classifying was significant. The Kappa coefficient between the results of two raters was 81.1%.
Conclusion: It seems that the BCAT has good psychometric properties to recognize cognitive impairment among Iranian older adults.
