  • The current study was designed to examine the effects of family history of alcohol use disorders on spectral electroencephalographic (EEG) sleep measures obtained in a sample of youth with depression. We evaluated sleep in 32 depressed youth (8-16 years of age) with and without a family history of alcohol use disorders. Eighteen of the participants (10 males and 8 females) reported a positive paternal history of alcohol use disorders and made up the family history positive (FHP) group. Power-spectral analyses revealed that increased power in the 7.50-11.00 Hz band (slow alpha) was associated with boys in the FHP group for the first and second non-rapid eye movement (REM) periods, second REM period, awake during the night, and entire night period. Results also showed increased power in the higher alpha frequencies (11.00-12.25 Hz) for non-REM, REM, and awake periods. A significant increase in spectral power was also observed in boys in the FHP group in the delta frequencies (0.75-4.50 Hz) during the second REM period. These findings are consistent with results from previous studies, demonstrating that EEG alpha power is positively associated with a family history of alcohol use disorders.
