Extrapyramidal dysfunction in alcoholism

R L Weir

    Journal of the National Medical Association
    |February 1, 1980
    PubMed
    Summary
    This summary is machine-generated.

    Excessive alcohol intake can cause neurologic disorders, including involuntary movement issues like tremors and jerking. These symptoms are often linked to alcohol withdrawal, cerebellar dysfunction, or liver problems.

    Area of Science:

    • Neurology
    • Toxicology

    Background:

    • Chronic excessive alcohol consumption leads to subnutrition and withdrawal.
    • Alcohol abuse is associated with various neurologic disorders, particularly involuntary movement disorders.

    Purpose of the Study:

    • To review neurologic disorders associated with chronic alcohol ingestion.
    • To categorize alcohol-induced involuntary movement disorders into three main groups: withdrawal tremulous states, cerebellar system dysfunction, and hepatic-related disorders.

    Main Methods:

    • Literature review and synthesis of existing research on alcohol-related neurologic disorders.
    • Categorization of movement disorders based on their association with alcohol withdrawal, cerebellar function, and hepatic encephalopathy.

    Main Results:

    Related Experiment Videos

    • Alcohol withdrawal commonly manifests as tremor, peaking 10-20 hours after cessation of drinking.
    • Infants born to alcoholic mothers can experience tremulous states.
    • Hepatic encephalopathy is associated with flapping tremors, other tremors, and jerking movements.
    • Chronic porto-systemic encephalopathy presents with choreoathetoid movements and coarse tremors.

    Conclusions:

    • Alcohol abuse significantly impacts the nervous system, causing diverse involuntary movement disorders.
    • Understanding these movement disorders is crucial for diagnosing and managing alcohol-related neurological complications.
