We observed nominal differences in resting state EEG coherence patterns of alcohol dependent individuals who had attempted suicide compared to those who had not attempted suicide. However, only two findings withstood multiple test correction: decreased right hemispheric frontal-parietal theta (3–7Hz @ F8-F4-P8-P4) and decreased interhemispheric temporal-parietal alpha (7–12 Hz @ T8-P8-T7-P7) EEG resting-state coherences (p < 0.001, Supplemental Fig. 3). Exploratory analyses within a subset of individuals who had available neurocognitive measures is available in the supplementary information.
