ADDICTIVE MECHANISMS • Physical vs. Psychological addictions
• Tissue Dependence: adaptation of body to constant presence of a substance
• Conditioned response: Any stimulus experienced repetitively or that has a strong enough impact on our brain, begins to
change our structure accordingly
physical
psychological

Treatment Initial time
The brain is slow to change back.
Often sets us up for relapse

One big issue is…
Even though a person stops/cuts back use, the brain imbalance will often stay close to the same. This leaves behind:
Depression Anger
Anxiety Confusion
Bipolar-type symptoms Dulled affect
Inability to control emotions ADHD symptoms

Let’s say this is the brain of someone with addiction as his/her main issue

Once the addictive brain processes are changed in the brain, the brain is still out of balance in other areas.
