Physical connections create pathways in the brain that can be altered when we learn something new. These changes to the brain can be seen with medical imagery. Addiction is a learned behavior that changes the brain as well. The brain becomes conditioned to want the substance. Through counseling and other behavioral modification we can actually, in some cases, change the brain physically. By changing our environment, starting a new job, new hobbies and friends, all will alter our brain in some way. It is possible to undo some of the changes that occurred while addicted. Therapy will recondition the brain closer to pre-addiction status. This will better prepare the patient for a time when they may no longer require medication.
Medication alone can reduce cravings and withdrawal, but recovering from an addictive disorder requires a rewiring of the brain and medication alone is not enough. Attention to eliminating things in life that cause stress or depression will help minimize the chance of relapse. Disassociating with friends who are in active addiction can be difficult but very necessary. An experienced counselor/therapist will be able to teach other techniques that will further help undo some of the brain changes and conditioned learning that occurred while becoming and remaining addicted.
