Dopamine and Addiction: The Science of Cravings - Addiction Basics EP2

Addiction neuroscience explained. Dopamine, cravings, brain recovery, and neuroplasticity — backed by research.If you’ve ever wondered how addiction works in the brain, this is the science most people never hear.Addiction is not about pleasure. It’s about dopamine-driven learning, reward prediction error, and long-term changes in the brain’s reward system.In this evidence-based breakdown, Dr Ferghal Armstrong explains:

🧠 How Addiction Rewires the BrainThe real role of dopamine in addiction

How the nucleus accumbens strengthens habit loops

Why cues trigger cravings before conscious choice

⚠️ The 3 Brain Changes in Addiction

Cue sensitisation and trigger amplification

Reduced response to natural rewards (dopamine tolerance)

Prefrontal cortex impairment and weakened impulse control

🔄 Brain Recovery and Neuroplasticity

What brain imaging studies show after abstinence

How dopamine transporter levels normalise

Why recovery takes months — but is measurable

This video covers:

Addiction neuroscience, dopamine explained, reward system function, executive control, relapse science, cognitive behavioural therapy, brain healing after drugs, and neuroplasticity recovery.

If you are researching addiction recovery, studying neuroscience, supporting someone in recovery, or simply want to understand how cravings work, this video provides clarity without stigma.

Recovery is not a motivational theory.It’s a measurable brain change.
