The Neuroscience of Addiction

Abstract

This chapter offers a succinct synopsis of the complex interplay between addiction and neurology, along with recommendations for creating efficacious treatment plans. This chapter investigates the brain mechanisms behind addictive behaviours, with an emphasis on dopaminergic pathways, reward circuits, and neurotransmitter imbalances, acknowledging addiction as a complex neurobiological issue. The chapter explores modern neuroscientific treatment modalities, such as neurotransmitter system-targeting medications, maladaptive behavior treatment with cognitive-behavioral therapy (CBT), and positive reinforcement-based contingency management. Emerging technologies like brain stimulation and neurofeedback are introduced in addition to traditional therapy. These technologies, which include transcranial magnetic stimulation (TMS) and EEG-based neurofeedback, are new solutions that make use of neuroscientific principles.
