Mini-Mental Status Examination: is it appropriate for screening in Thai elderly?

Area of Science:

• Gerontology
• Neuropsychology
• Public Health

Background:

• Cognitive impairment screening is crucial for elderly populations.
• The Mini-Mental Status Examination (MMSE) is a widely used cognitive screening tool.
• Assessing the validity of the MMSE in diverse cultural and socioeconomic contexts is essential.

Purpose of the Study:

• To evaluate the appropriateness of the Mini-Mental Status Examination (MMSE) for assessing cognitive function in elderly Thai individuals.
• To identify demographic and environmental factors influencing MMSE scores in Thailand.

Main Methods:

• The study involved three distinct samples, each comprising fifty elderly subjects from varied residential locations across Thailand.
• Data were collected on literacy, age, gender, primary occupation, and place of residence.
• Multiple regression analysis was employed to determine the influence of these factors on MMSE scores.

Main Results:

• Literacy, age, gender, occupation, and place of residence were all found to be associated with MMSE scores.
• Multiple regression analysis revealed that literacy and place of residence exerted strong, independent effects on MMSE performance.
• These findings indicate potential biases in the MMSE when applied to the Thai elderly population.

Conclusions:

• The use of the Mini-Mental Status Examination (MMSE) as a standard screening tool for cognitive impairment in Thailand may be inappropriate due to significant influences from literacy and residence.
• There is a need for the development and validation of novel cognitive screening instruments that are less susceptible to educational and environmental factors in the Thai context.
• Future research should focus on creating culturally sensitive and contextually relevant tools for accurate cognitive assessment in diverse elderly populations.
