Assessment of cognitive function in alcoholics by computer: a control study.

C Acker, W Acker, G K Shaw

    Alcohol and Alcoholism (Oxford, Oxfordshire)
    |January 1, 1984
    PubMed
    Summary

    Alcoholics showed significant cognitive impairments on 18 of 23 computer-administered tests compared to controls, even after accounting for intellectual differences. These computer tests offer practical advantages over traditional methods.

    Area of Science:

    • Neuroscience
    • Psychology
    • Cognitive Science

    Background:

    • Alcoholism is a chronic relapsing brain condition.
    • Cognitive deficits are common in individuals with alcohol use disorder.
    • Assessing cognitive function in alcoholics is crucial for understanding long-term effects.

    Purpose of the Study:

    • To evaluate cognitive function in alcoholics compared to controls.
    • To assess the utility of computer-administered cognitive tests.
    • To determine if cognitive deficits persist after controlling for baseline intellectual capacity.

    Main Methods:

    • 103 individuals with alcoholism and 90 controls completed six computer-administered cognitive tests.
    • Performance was compared between groups.

  • National Adult Reading Test (NART) was used to estimate pre-existing intellectual capacity.

    • Main Results:

    • Alcoholics performed significantly worse than controls on 18 out of 23 cognitive measures.
    • Statistical analysis accounted for differences in intellectual capacity (NART).
    • Computer-administered tests demonstrated practical advantages over conventional assessment procedures.

    Conclusions:

    • Chronic alcoholism is associated with widespread and significant cognitive impairments.
    • Computerized cognitive testing is a viable and efficient method for assessing cognitive function in clinical populations.
    • Cognitive deficits in alcoholism are not solely attributable to lower baseline intelligence.
