Abstract

Drug addiction is a complex disorder of the central nervous system, characterized by the loss of control over drug seeking and drug taking, and by the risk of relapse, even after a long period of abstinence. This disease may have its source in a disturbed function of brain reward system, disturbed associative learning and a disturbed balance of drive-related behaviors, which control appetitive reactions aimed at seeking contact with an addictive substance. Here we review concepts and theories of drug addiction and postulate that dysfunction of drive satisfaction leads to the sustained activation related to the current drug-related drive thus leading to the drug craving and relapses of addictive behavior.
