The role of brain- behavioral systems with addiction relapse

Previous studies have shown that impulsive or uncontrolled behaviors in addicts to obtain the drug and drug abuse may be due to overcome one of the brain/behavioral systems. In this study we sought to answer the question whether the overcoming can be associated with relapsing or not?
The method of research was causative-comparative. To achieve our aim, we categorized addicted people with relapse and non-relapse in two groups, each group comprising 31 subjects were selected by available sampling method and evaluated on Gray-Wilson personality questionnaire. Data analysis has been done for comparison on each independent group by T Test.
The results, indicated that behavioral activation system and fight subscale in addicts with relapse was significantly different with (greater than) non-relapse people. The behavioral inhibition system, was not significantly different in two groups.
Results showed, specific biological characteristics can be considered as risk factors for addiction, moreover, in the field of prevention and treatment, consideration of these characteristics and sensitivities are very useful.
