Nov 2, 2023 · Based on decades of animal and human research, a scientifically validated neurobiological model of addiction consists of a repeating cycle of 3 distinct stages. This model provides an insightful way to understand the signs of addiction, approaches to …
Addiction is a brain disease, with both biological and behavioral risk factors. Addiction consists of specific stages, that each involve different brain regions and different neurotransmitters. Addiction disrupts brain circuits involved in judgment and decision-making, so that “saying no” becomes very difficult.
