    The Mental Status Questionnaire (MSQ) and Face-Hand test effectively screen for impaired brain function in the elderly. These tests correlate with intellectual performance across education levels, identifying deficits in older adults.

    Area of Science:

    • Gerontology
    • Neuropsychology
    • Cognitive Assessment

    Background:

    • Assessing behavioral problems in the elderly requires reliable indicators of impaired brain function.
    • Existing methods for evaluating cognitive status in older adults need validation.

    Purpose of the Study:

    • To evaluate the relationship between two mental status measures (MSQ and Face-Hand test) and intellectual performance.
    • To determine how education level influences the assessment of brain function using these tests.

    Main Methods:

    • 153 geriatric clinic patients (inpatients and outpatients) were assessed.
    • Intellectual performance was measured using 8 learning and memory tests.
    • The Mental Status Questionnaire (MSQ) and Face-Hand test were used to rate brain function.

    Main Results:

    • Positive ratings for impaired brain function on MSQ and Face-Hand tests correlated with lower intellectual performance across all education levels.
    • Individuals with higher education and mild impairment scores performed better than less educated individuals without dysfunction but worse than peers with intact cognition.
    • Greater intellectual deficits were observed with more test errors and when both screening tests indicated impairment.

    Conclusions:

    • The MSQ and Face-Hand test are valuable screening tools for detecting intellectual deficits associated with impaired brain function.
    • These tests are effective in a diverse geriatric population.
    • Education level is an important factor to consider when interpreting cognitive assessment results in the elderly.
