Substance-Related and Addictive Disorders

Substance-Related and Addictive Disorders are characterized by abusing the activation of the brain reward system through certain behaviors or the use of pharmacological substances. This often results in a sense of increased pleasure, or a “high”, encouraging reinforcement of behaviors and actions that are detrimental to or neglectful of daily activities. Due to insufficient research, repetitive behaviors that have been coined as behavioral addictions (e.g., sex addiction, exercise addiction, or shopping addiction) are excluded from this chapter.
