Two Swedish studies have suggested the following 2 types of male alcoholism:

  • Type 1 characteristics include (1) onset in adulthood (early twenties), (2) drinking to relieve anxiety, and (3) inherited but requires an environmental trigger.

  • Type 2 characteristics include (1) an association with criminal behavior (sociopathy), (2) onset in teen years, and (3) drinking to get high.

  • Sons of persons with type 2 alcoholism are 7 times more likely to develop type 2 alcoholism compared with the general population.

  • The theories suggested from these studies are controversial and require confirmation in additional populations.
