As the brain matures, experiences prune excess neural connections while strengthening those that are used more often. Many scientists think that this process contributes to the steady reduction in gray matter volume seen during adolescence (depicted as the yellow to blue transition in the figure). As environmental forces help determine which connections will wither and which will thrive, the brain circuits that emerge become more efficient. However, this is a process that can cut both ways because not all tasks are desirable. The environment is like an artist who creates a sculpture by chipping away excess marble; and just like bad artists can produce bad art, environments with negative factors (like drugs, malnutrition, bullying, or sleep deprivation) can lead to efficient but potentially harmful circuits that conspire against a person's well-being.
Alcoholism can also be categorized into 2 types: early-onset (biological predisposition to the disease) or late-onset (brought on by environmental or psychosocial triggers). Understanding and studying the difference between early- and late-onset alcoholism facilitate the selection of the appropriate therapy. Drugs that affect the rewarding behavior of neural activities, such as ondansetron, naltrexone, topiramate, and baclofen, have been shown to alter drinking behavior. 
The best alcohol addiction treatment programmes combine detox with rehab therapies and follow-up with aftercare services. This is the kind of addiction treatment you need if you are suffering from alcoholism. It is a treatment that is administered with the knowledge that what you are suffering from is a chronic illness rather than just a lack of willpower.
Substance abuse therapy: Used as a part of many inpatient and outpatient programs, therapy is one of the cornerstones of drug addiction treatment. Individual, group and family therapy help patients and their loved ones understand the nature and causes of addiction. Therapy teaches coping strategies and life skills needed to live a productive, sober life in the community. For individuals with a co-occurring mental illness, intensive psychotherapy can also address psychiatric symptoms and find the underlying issues that contribute to addiction.
