title: New view on treatment of drug dependence.
abstract: In the 1960s, discovery of pleasure system (defined as reward system) in the brain that may underlie drug reward and addiction encouraged many scientists to investigate the mechanisms by which drug abuse affects central nervous system function. In this regard, investigators developed several drugs targeting the brain reward system for drug dependence therapy. However, no positive results obtained in drug addiction treatment. It seems that more brain systems other than brain reward system must be considered in this regard.
