The conceptual basis of addiction memory, allostasis and dual processes, and the classical therapy of addiction

PURPOSE: In recent years, research has yielded new information regarding the impact of intense, long-term alcohol consumption on the development of permanent changes in the central nervous system. The present study examines the mechanisms related to the existence of addiction memory, sensitization and allostasis. A dual-process model was also created, which analyses the role of conscious and automatic mechanisms in the functioning of addicts. The aim of the article is to present these mechanisms and to consider the implications of their existence for the course of therapy. VIEWS: The mechanisms analysed shed new light on some of the negative phenomena occurring during and after therapy, such as frequent abstinence after treatment, switching addictions, and returning to drinking after a long period of abstinence. The existence of these mechanisms should also change the character of addiction therapy, which has so far focused mainly on conscious aspects and ignored the existence of automatic ones. Attempts are already being made to implement the dual-process model in addiction therapy. CONCLUSIONS: A better understanding of the mechanisms resulting from the dual-process model can significantly influence perspectives regarding functioning in addiction and the course of therapy. These processes merit further research, as do possible therapeutic interventions based on them.
