Clinical and temperamental differences between early- and late-onset alcoholism in Korean men.

The aims of this study were to elucidate the clinical and temperamental differences between early- and late-onset alcoholism among Korean men and to ascertain the validity of Cloninger’s typology model of alcoholism for Koreans. There were several distinct clinical and temperamental differences between early- and late-onset alcoholism among Korean male alcoholic patients. It is suggested that the age at the onset of alcoholism can be used to discriminate alcoholic subtypes. Our data also partly support Cloninger’s typology of 2 types of alcoholic individuals.
