Addiction has been increasingly recognized as a neurodevelopmental and neuropsychiatric disorder rooted in dysregulation of the brain’s reward-stress-executive function systems. Central to this neurological dysregulation is the hypothalamic orexin system, which modulates dopamine pathways involved in reward, motivation, and compulsive behavior. This paper explores the role of orexin in addiction and its complex interactions with the hypothalamic-pituitary-adrenal (HPA) axis, prefrontal cortex (PFC), amygdala, and nucleus accumbens. Special emphasis is placed on how orexin dysfunction contributes to addiction vulnerability in individuals, especially young people with psychiatric disorder comorbidities, such as attention deficit-hyperactivity disorder (ADHD) and emotional disturbances (ED). Additionally, this paper proposes educational therapy (EdTx) as a neuroscience-informed, non-pharmacological intervention that directly targets orexin-dopamine- reinforcement circuits. Through structured reinforcement, executive function support, cue exposure, and psychoeducation, EdTx offers a brain-based intervention strategy aligned with developmental frameworks. This integrative approach holds promise for promoting recovery, neuroplastic resilience, and sustained behavioral change in young people with addiction.
