Addiction and the Brain

The Addiction and the Brain course explores how substance use and addictive behaviors alter neural pathways, disrupt reward circuitry, and reshape cognitive and emotional functioning. 

It examines the interplay between genetics, environment, trauma, and neurobiology, highlighting how dopamine, stress systems, and impaired executive functioning contribute to the cycle of craving, tolerance, and dependence. 

Through this lens, addiction is understood not as a moral failing but as a chronic, relapsing brain disorder influenced by complex biopsychosocial factors. 

The course emphasizes the importance of evidence‑based interventions, neuroplasticity, and compassionate, person‑centred care, equipping learners with a deeper understanding of how the brain adapts—and how recovery is both possible and supported through informed practice.
