Abstract

Background: In Vietnam, dementia has become an increasingly important health problem among the elderly. In order to assess memory loss, clinicians need objective and highly reliable instruments to identify memory impairment. One of them is the CERAD Word list memory task, – a relatively brief scale, - that is commonly used to assess cognitive function in individuals who are at risks to developing Alzheimer’s disease.

Objectives: To describe the characteristics of the initial assessment and evaluate the reliability of the Vietnamese version of the CERAD Word list memory task.

Methods: The test-retest reliability of the Vietnamese version of the CERAD Word list memory task were determined in 12 participants, who are healthy Vietnamese people aged 40 years or older and have normal cognitive functions and activities of daily living (no memory loss, independent living activities, MMSE score ≥ 27) in a Memory and Dementia Unit in Ho Chi Minh City.

Results: All participants were able to learn and remember verbal information well, with the median of Word List Memory, Word List Recall, Word List Recognition scores of 25.5, 9.0, 10.0, respectively. The scale showed stability and reliability that were both high and statistically significant. Specifically, test-retest reliabilities of the Word List Memory, Word List Recall, Word List Recognition tasks were 0.81, 0,86, 0.77, respectively (Spearman correlation coefficient, p < 0.05).

Conclusion: The Vietnamese version of the CERAD Word list memory task is highly reliable in the identification of early stages of cognitive impairment.
