    This study identified key indicators from mental status exams and neurological signs to predict cognitive impairment. A brief screening tool was developed using these factors for bedside assessment of diffuse cerebral dysfunction.

    Area of Science:

    • Neuropsychology
    • Neurology
    • Cognitive Science

    Background:

    • Cognitive impairment affects millions globally, necessitating accurate and accessible diagnostic tools.
    • Early detection of diffuse cerebral dysfunction is crucial for timely intervention and management.

    Purpose of the Study:

    • To correlate specific mental status examination questions and neurological signs with cognitive impairment.
    • To develop a brief, bedside screening examination for identifying diffuse cerebral dysfunction.

    Main Methods:

    • Abnormal responses to 13 mental status questions and 32 neurological signs were assessed.
    • Cognitive impairment was measured using the Halstead-Reitan Neuropsychological Battery.
    • Statistical correlation was performed to identify predictive factors.

    Main Results:

    • Thirteen specific factors demonstrated utility in predicting cognitive impairment.
    • These factors were combined to create a brief screening examination.
    • The screening tool showed promise for bedside application.

    Conclusions:

    • A concise set of mental status and neurological indicators can effectively predict diffuse cerebral dysfunction.
    • The developed screening examination offers a practical tool for rapid bedside cognitive assessment.
    • Further validation of this screening tool in diverse clinical settings is warranted.
