developing alcoholism (Ehlers et al., 1996). While reduced EEG alpha power in male and female offspring of alcoholics has been reported (Finn and Justus, 1999), this was not related to comorbid traits of anxiety or antisocial personality. A distinctive low-voltage alpha variant (LVA), has been reported to be associated with a subtype of alcoholism that is associated with anxiety disorder (Enoch et al., 1999). LVA, which is characterized by an absence or very low-amplitude alpha rhythmicity, is found in 5–10% of individuals (Anokhin et al., 1992; Enoch et al., 1995). Ethnic variations may exist in the prevalence of LVA, EEG variants, and association with alcoholism or risk (Ehlers and Phillips, 2003).
