Addiction is a disease that affects an individual physically, psychologically, and mentally. Understanding this complex disease requires a holistic approach that goes beyond a person’s behavior.

After years of trying to get a better idea of addiction, Interpersonal Neurobiology (IPNB) emerged as a valuable framework that offers insights into the connection between the biological, psychological, and social factors contributing to substance use disorder.

What is Interpersonal Neurobiology?

Interpersonal Neurobiology refers to an interdisciplinary field that explores the connection between psychology, neuroscience, and relationships. IPNB examines how our interpersonal experiences constantly shape the brain’s structure and function.

When it comes to addiction, Interpersonal Neurobiology offers a detailed view that looks at how social connections and relationships play a role in substance use.

Interpersonal Neurobiology and Drug Addiction

Interpersonal Neurobiology helps us understand drug addiction in the following areas:

  • Brain changes in addiction – IPNB broadens our understanding of the neurobiological changes that occur in addiction. Over time, substance use can impact the brain’s reward system, altering neural pathways and affecting an individual’s decision-making processes. IPNB helps us see how changes in the brain are affected by our connections with others thanks to our personal interactions and our social environment.
  • Social support and recovery – IPNB reinforces the importance of social support in addiction recovery. Positive social interactions and supportive relationships can contribute to the brain’s neuroplasticity, leading to other adaptive changes that support recovery. Therefore, a strong social support system is a key component of addiction treatment as it promotes individual resilience and long-term well-being.
  • Emotional regulation and cravings – IPNB sheds light on how interpersonal experiences influence emotional regulation and consequently, addiction cravings. Alcohol or drugs may temporarily alleviate emotional distress and individuals with limited emotional regulation skills may turn to them as a coping mechanism. IPNB-based interventions focus on helping those in recovery to develop healthier emotional regulation strategies through social connection and support.
  • Early attachment and vulnerability – Interpersonal Neurobiology highlights the crucial role played by early attachment experiences in shaping the brain’s neural circuits connected to emotional regulation and stress response. People with insecure attachment patterns may be more vulnerable to addiction and substances can help them cope with their emotional dysfunction. Recognizing the impact of early relationships is vital for comprehensive addiction treatment.
  • Therapeutic approaches – IPNB guides how we approach treating addiction by emphasizing the therapeutic relationship. This helps us develop addiction treatment plans that integrate cognitive-behavioral interventions, mindfulness practices, and group therapies. Thanks to IPNB, we know that these factors can positively impact brain function and reshape neural pathways.
