Bridging Neuroplasticity and Addiction: Examining Awareness Integration Theory as a Promising Treatment Approach
Main Article Content
Abstract
Substance use and behavioral addictions are escalating on a global scale. The Global Burden of Disease Study underscores a rising impact on disability-adjusted life years attributable to substance use. This challenge influences families, communities, healthcare infrastructure, and legal systems; nevertheless, the majority of individuals suffering from substance use disorders face challenges in seeking and finding a sustainable treatment methodology that can leave a long- lasting imprint on the process of recovery. The human brain possesses a remarkable capacity for change and adaptation throughout an individual's lifespan, a phenomenon referred to as neuroplasticity. This capability is essential for processes such as learning, memory, and recovery from injuries. Notably, the brain retains its ability to adapt during adulthood. Consequently, addiction is not solely attributable to diminished willpower but also involves significant, maladaptive alterations in neural circuits. Practices like mindfulness boost mental well-being by increasing cortical thickness, reducing amygdala reactivity, and improving brain connectivity and neurotransmitter levels. This enhances emotional regulation, cognition, and stress resilience. Research shows mindfulness induces neuroplasticity. For example, Mindfulness-Based Stress Reduction (MBSR) improves emotional processing and sensory perception and lowers anxiety and depression. Evidence supports the psychological model, such as Awareness Integration Theory (AIT), in promoting neurogenesis and neuroplasticity in adults. Studies indicate AIT's influence on the autonomic nervous system (ANS) could help those with depression and anxiety through an integrative approach using mindfulness and cognitive, emotional, behavioral, and trauma-informed approaches, aiming to reframe negative thoughts and reduce amygdala activity. This review examines adult neuroplasticity research, emphasizing its potential and encouraging further study.
