Introduction to the Study
The study is currently in the preparation phase for publishing results.

1. Overview
The number of people with dementia in Vietnam is projected to increase to 1.2 million by 2030. Currently, there is little data on the normative values of neuropsychological tests used to assess cognition in Vietnam. Diagnosis of dementia still relies on reference values from foreign studies.

2. Objectives
The objectives of the study include:

• Determining the normative values of a neuropsychological test battery for cognitive assessment.
• Investigating the relationship between factors such as age, education level, and gender on cognitive function changes in Vietnamese adults.

3. Methods
Study participants were recruited from two dementia treatment centers in Ho Chi Minh City. Inclusion criteria included: age ≥ 40, normal cognition and function, and MMSE score ≥ 25. The neuropsychological tests surveyed include the CERAD Word List, Digit Span Test, Trail Making Test, Animal Naming Test, and Clock Drawing Test.

Conclusion:
We will publish the results and provide the link to the article once the study is published in a reputable journal.
