The Disease Model

This model proposes that addiction is not a sign of moral weakness but it is a disease of the brain. Like any other illness it is chronic, progressive, and fatal if left untreated. A vast amount of research supports this model as addiction contributes to physical changes in the brain structure. Through research it has been demonstrated that addiction desensitizes the reward circuits of the brain, reinforces conditioned responses surrounding the substance, and decreases the brain's ability to self-regulate and make decisions.
