In Vietnam, the population is currently aging. According to statistics in 2009, the elderly accounted for 9% of the total population, with an average life expectancy of 70.2 years for men and 75.6 years for women. The aging population has led to an increase in the prevalence of neurological diseases, typically dementia.

Dementia is a common condition in the elderly. Performing dementia assessment tests will help diagnose this condition, thereby providing appropriate intervention options for each patient.
