    This study found no strong link between electroencephalogram (EEG) abnormalities and suicidal behavior in psychiatric patients. Further research may be needed for specific patient groups, like those threatening self-harm.

    Area of Science:

    • Neuroscience
    • Psychiatry
    • Clinical Psychology

    Background:

    • Previous research suggested a higher prevalence of paroxysmal electroencephalogram (EEG) abnormalities in suicidal psychiatric inpatients.
    • The association between EEG findings and suicidal behavior requires further investigation in diverse patient populations.

    Purpose of the Study:

    • To investigate the relationship between scalp EEG abnormalities and suicidal behavior in a cohort of psychiatric inpatients.
    • To validate or refute previous findings on the association between EEG abnormalities and suicidal ideation.

    Main Methods:

    • Administered the Zung Index of Potential Suicide and performed scalp electroencephalogram (EEG) on 216 consecutively admitted VA psychiatric inpatients.
    • Analyzed the data to determine the prevalence of EEG abnormalities in suicidal versus nonsuicidal patient groups.

    Main Results:

    • A slightly higher rate of EEG abnormality was observed in suicidal patients (14.9%) compared to nonsuicidal patients (6.6%).
    • Statistical analysis did not support a general or specific association between overall or paroxysmal EEG abnormality and suicidal behavior.
    • Preliminary data suggested potential value in further EEG studies for patients categorized as 'Threatener' in suicidal behavior.

    Conclusions:

    • The study failed to confirm a significant association between EEG abnormalities and suicidal behavior in this VA psychiatric inpatient population.
    • Findings do not support Struve's hypothesis regarding paroxysmal EEG abnormality and suicidal inpatients.
    • Further EEG research may be warranted for specific subgroups, such as individuals exhibiting threatening suicidal behavior.
