Dr. Suzanne Thomas, a psychologist with her PhD in experimental psychology, talks about addiction as a disorder of the brain. She defines addiction and describes the actual neurological changes that occur when a person develops substance addiction. She focuses on the hypersensitive motivation pathway and explains that cessation in substance use allows for some recovery of the affected brain systems. Dr. Thomas concludes this mental health podcast by addressing the notion of food addiction, explaining that research is not yet conclusive on this topic.
