The Modified Mini Mental State Exam (3MS) shows compressed cognitive scores in clinical trials. Associations with age, education, and ethnicity vary, requiring careful interpretation across diverse populations.

Area of Science:

  • Gerontology
  • Cognitive Neuroscience
  • Clinical Trials

Background:

  • The Modified Mini Mental State Exam (3MS) is a common tool for assessing global cognitive function.
  • Its performance and score distribution within clinical trial settings are not well-established.
  • Understanding 3MS score characteristics in trials is crucial for accurate cognitive assessment.

Purpose of the Study:

  • To analyze the distribution of 3MS scores in the Women's Health Initiative Memory Study (WHIMS).
  • To identify demographic variations (age, education, ethnicity) in 3MS scores within this cohort.
  • To explore the underlying factor structure of the 3MS exam in a clinical trial population.

Main Methods:

  • Administered the 3MS to 7,480 women aged 65-80 participating in a postmenopausal hormone therapy trial.

  • Employed general linear models to examine demographic differences in 3MS scores.
  • Utilized factor analysis to investigate the correlational structure of 3MS subscales.

    • Main Results:

    • 3MS scores in WHIMS exhibited a compressed distribution compared to general population data, with a mean of 95.1.
    • Scores decreased with age and increased with education, but these relationships differed significantly across ethnic groups (p<0.0001).
    • Four factors explained 37% of the variance; these factors were associated with education, ethnicity, and age.

    Conclusions:

    • Baseline 3MS scores in the WHIMS cohort, despite a narrow distribution, maintained significant associations with age and education.
    • These demographic associations demonstrated ethnic variability, highlighting the need for cautious interpretation of 3MS data across different populations.
    • The findings underscore the importance of considering demographic context when using the 3MS in clinical trials.
