ASAM releases new definition of addiction
Date:8/14/2011

disease or diabetes, so it must be treated, managed and monitored over a life-time.

Two decades of advancements in neurosciences convinced ASAM that addiction needed to be redefined by what's going on in the brain. Research shows that the disease of addiction affects neurotransmission and interactions within reward circuitry of the brain, leading to addictive behaviors that supplant healthy behaviors, while memories of previous experiences with food, sex, alcohol and other drugs trigger craving and renewal of addictive behaviors. Meanwhile, brain circuitry that governs impulse control and judgment is also altered in this disease, resulting in the dysfunctional pursuit of rewards such as alcohol and other drugs. This area of the brain is still developing during teen-age years, which may be why early exposure to alcohol and drugs is related to greater likelihood of addiction later in life.

There is longstanding controversy over whether people with addiction have choice over anti-social and dangerous behaviors, said Dr. Raju Hajela, past president of the Canadian Society of Addiction Medicine and chair of the ASAM committee on the new definition. He stated that "the disease creates distortions in thinking, feelings and perceptions, which drive people to behave in ways that are not understandable to others around them. Simply put, addiction is not a choice. Addictive behaviors are a manifestation of the disease, not a cause."

"Choice still plays an important role in getting help. While the neurobiology of choice may not be fully understood, a person with addiction must make choices for a healthier life in order to enter treatment and recovery. Because there is no pill which alone can cure addiction, choosing recovery over unhealthy behaviors is necessary," Hajela said.

"Many chronic diseases require behavioral choices, such as people with heart disease choosing to eat healthier or begin exercising, in addition to medical or s
