The EEG in chronic alcoholism.

B van Sweden

    Clinical Neurology and Neurosurgery
    |January 1, 1983
    PubMed
    Summary

    Electroencephalography (EEG) may help differentiate psychotic syndromes in alcoholism, despite non-specific abnormalities. Certain EEG patterns are common in conditions like delirium tremens, aiding diagnosis.

    Area of Science:

    • Neuroscience
    • Psychiatry
    • Clinical Neurophysiology

    Background:

    • Psychosis in alcoholism is complex and often discussed without considering electroencephalography (EEG).
    • EEG abnormalities in alcoholism are generally non-specific.
    • Identifying specific EEG patterns could aid in understanding psychosis pathophysiology.

    Purpose of the Study:

    • To investigate the utility of EEG in elucidating the pathophysiology of psychotic conditions in alcoholism.
    • To determine if EEG can serve as a diagnostic tool for differentiating psychopathological syndromes in alcoholic patients.

    Main Methods:

    • Review of existing literature on EEG findings in alcoholism-related psychosis.
    • Analysis of common EEG patterns observed in specific clinical conditions like delirium tremens and amnestic-confabulatory states.
    • Discussion of the pathogenetic role of tissue hypoxidosis.

    Main Results:

    • While no single EEG sign is pathognomonic for psychosis in alcoholism, certain patterns are more frequent in specific syndromes.
    • EEG abnormalities, though non-specific, can be associated with conditions like delirium tremens.
    • Tissue hypoxidosis is proposed as a significant factor in the development of psychosis.

    Conclusions:

    • EEG may offer valuable insights for differentiating psychopathological syndromes in alcoholism.
    • Specific EEG patterns can be indicative of certain clinical states, aiding diagnostic processes.
    • Understanding EEG patterns contributes to elucidating the pathophysiology of psychosis in alcoholism.
