Although the debate over addiction continues, there is currently hard evidence demonstrating that addiction is, in fact, a brain disease. As human beings we are, of course, much more than our neurobiology, and for this reason the most effective drug and alcohol rehabs attend to not only individual differences, but also to the needs of the whole person: body, mind, social/cultural, and spiritual. The best drug and alcohol treatment programs, in other words, are based on a Bio-Psycho-Social-Spiritual model of addiction.
To fully appreciate the necessity for the addicted individual of drug and alcohol rehab, an explanation of why addiction is a disease, and what happens in the brain of an alcoholic or addict, is in order. In his book titled Addiction and its accompanying CDs on “Disease” and “The First Year of Recovery”, Kevin McCauley, M.D., presents a thoroughly convincing argument for why addiction is a brain disease, and for how addiction, seemingly caused by a behavior that is a choice, actually arises from structural and chemical differences in the brains of addicted individuals. In explaining these differences, Dr. McCauley additionally proves that addiction fits the disease model of medicine. The Disease Model, which arose out of Germ Theory about a century ago, was the first causal model in medicine in this country. Before this model, doctors simply chased down symptoms.
