What schedule-induced polydipsia can tell us about alcoholism.

An animal model of chronic and excessive voluntary (unforced) alcohol ingestion is presented in which, by drinking, animals produce repeated, substantial elevations in blood ethanol concentration and develop physical dependence. The overindulgence is elective in that ethanol is chosen in preference to certain other fluid-ingestive alternatives. Beside the usual demonstrations of acutely compromised motor performance, tolerance development, cross-tolerance, etc., the model demonstrates that the consequences of even short, but continued, daily drinking episodes results in the disruption of reinforced behavior that occurs later in the day when blood ethanol is absent (impaired general functioning). The conditions which induce the ethanol overindulgence can generate a variety of behavioral excesses which places alcoholism in a context of environmentally determined malfunctions that are subject to therapeutic change by altering situational parameters. Efficacious experiments utilizing therapeutic and preventive strategies are described that may serve as suggestions for corresponding human alcoholism intervention strategies.
