Objective: The Alzheimer Disease 8 (AD8) is a simple and short informant-based tool that could assist in the screening of early stages of dementia. This study aimed to explore preliminary psychometric properties of the Greek version of the AD8 (CY-AD8) and its utility in cognitive screening in a large cohort of community dwellers over the age of 60.

Methods: Evaluation was made on 182 informant reports of community dwellers without a diagnosis of a neurological condition or dementia. The CY-AD8 scores were correlated with Mini Mental State Examination (MMSE) scores.

Results: Internal consistency of the CY-AD8 was acceptable (Cronbach α =0.827). The CY-AD8 correlated moderately with the MMSE (Pearson’s r = -.524 p < .001). Median split resulted in two groups based on the CY-AD8 scores. An independent samples t-test was conducted to examine whether there was a significant difference between group 1 (AD8=0-1) and group 2 (AD8=2+) in relation to their performance in MMSE. The test revealed a statistically significant difference between group 1 and group 2 in MMSE (t= 5.53, df =176, p < .001). Those with more symptoms on the CY-AD8  were significantly older than those with fewer symptoms.

Conclusions: The CY-AD8 is a useful screening tool for early detection of individuals who may be at risk for dementia, but still further investigation is needed to explore the psychometric properties of this tool.
