    The Mini-Mental State (MMS) test identified cognitive impairment in patients with abnormal brain CT scans. Cerebral atrophy, more than focal lesions, correlated with lower MMS scores, suggesting potential clinical utility.

    Area of Science:

    • Neurology
    • Neuropsychology
    • Medical Diagnostics

    Background:

    • Cognitive impairment assessment is crucial for neurological conditions.
    • The Mini-Mental State (MMS) test is a widely used cognitive screening tool.
    • Computerized tomographic (CT) scans provide structural brain imaging information.

    Purpose of the Study:

    • To evaluate the clinical usefulness of the Mini-Mental State (MMS) test in patients undergoing brain CT scans.
    • To determine the relationship between CT scan findings and cognitive performance on the MMS test.

    Main Methods:

    • 63 patients completed the Mini-Mental State (MMS) test.
    • Patients underwent computerized tomographic (CT) scans of the brain.
    • Cognitive scores were compared between patients with positive and negative CT scans.

    Main Results:

    • Patients with positive CT scans scored significantly lower on the MMS test than those with negative scans.
    • Cerebral atrophy showed a stronger association with cognitive impairment than focal cerebral lesions.
    • The MMS test demonstrated some ability to discriminate organicity.

    Conclusions:

    • The Mini-Mental State (MMS) test can be a useful tool for identifying cognitive impairment in certain neurological contexts.
    • Further refinement of MMS subtests may enhance its diagnostic accuracy and clinical utility.
    • Structural brain changes, particularly cerebral atrophy, are significantly linked to cognitive deficits detected by the MMS test.
