[Mini-Mental State Examination: psychometric characteristics in elderly outpatients]

Area of Science:

• Geriatric Medicine
• Neuropsychology
• Psychometrics

Context:

• Primary healthcare settings serve a large elderly population.
• Cognitive impairment screening is crucial for timely intervention.
• The Mini-Mental State Examination (MMSE) is widely used for cognitive assessment.

Purpose:

• To evaluate the psychometric properties of the MMSE in elderly primary care outpatients.
• To determine optimal cutoff points for dementia screening in this population.
• To investigate the influence of educational background on MMSE performance.

Summary:

• The study assessed the Mini-Mental State Examination (MMSE) in 303 elderly outpatients.
• Sensitivity, specificity, and predictive values were calculated, with an overall area under the ROC curve of 0.807.
• Optimal MMSE cutoff points varied significantly based on literacy, highlighting the need for tailored thresholds.

Impact:

• Findings emphasize the importance of considering educational level when interpreting MMSE scores in elderly individuals.
• This research can inform clinical practice for more accurate dementia screening in primary care.
• Optimized MMSE use can lead to earlier diagnosis and management of cognitive decline.
