Abstract

Objectives: To investigate the relationship between routine electroencephalography (EEG) and clinical characteristics in patients with alcoholism. Methods: A cross-sectional descriptive study was conducted on 60 patients with chronic alcoholism diagnosed according to ICD-10 (1992), who were treated at the Department of Psychiatry, Military Hospital 103, from June 2024 to June 2025. Clinical examinations and routine EEG recordings were performed within 24 hours of admission. Correlation between changes in EEG recordings and clinical characteristics of chronic alcoholism was analyzed. Results: The mean age of patients was 48.2 ± 7.7 years, and the mean duration of alcohol consumption was 23.6 ± 7.6 years. Alcohol withdrawal syndrome was observed in 60% of patients, and psychosis was observed in 33.3%. The longer duration of alcohol consumption, the lower alpha wave index (r = -0.272; p < 0.05), and the higher beta wave frequency and index (r ≈ 0.3; p < 0.05). Abnormal EEG findings were more common in the group with psychosis (70% vs. 37.5%; p < 0.05) and in the group with a greater number of dependence symptoms (9.97 ± 1.27 vs. 8.87 ± 1.59; p < 0.01). Conclusion: There was an increase in EEG excitability, a decrease in alpha rhythm index, and increases in the beta rhythm frequency and beta rhythm index, which were related to the duration of alcohol use, the severity of addiction symptoms, and the occurrence of psychotic symptoms in patients with chronic alcoholism.
