The concept of addiction has been broadened in recent years to include appetitive behaviors judged to be excessive in some sense: excessive drinking, drug-taking, gambling, eating and sexuality. Addiction is a disease in and of itself, characterized by compulsion, loss of control and continued used in spite of adverse consequences (Smith & Seymour, 2001). Addiction diseases account for almost one third of psychiatric hospitals capacity.

Leschner (2001, apud Coombs, 2004) considers that addiction is a brain disease, “a condition caused by persistent changes in brain structure and function”. Smith and Seymour (2001) noted that all addictions, whether chemicals or non-chemicals share three commons characteristics: compulsive use, loss of control and continued used despite adverse consequences.

For treating the persistent co-morbid disorders, besides cognitive-behavioral psychotherapeutics methods, the specialists recommend psycho-pharmacotherapy based on application of antidepressants and mood stabilizers.
