Brain Changes in Addiction
- Sensitization: Hyper reactivity to addiction related cues. Greater wanting but less liking
- Desensitization: Number pleasure response. Tolerance: need for higher doses or greater stimuli
- Hypofrontality: Weakened impulse control. Increases cravings.
- Altered stress response: Minor stress leads to cravings/relapse. Responsible for many withdrawal symptoms.
