Counseling and Physiology Class: Neurobiology of Addiction (or, A Good Thing Gone Bad)
In the first chapter of the American Society of Addiction Medicine’s textbook on addictions, Alan Leshner says this: “The brain of someone addicted to drugs is a changed brain; it is qualitatively different from that of a normal person in fundamental ways, including gene expression, glucose [sugar] utilization, and responsiveness to environmental cues.” Now, as Christians, what should we think of this? Our temptation is to go to one of two extremes. One extreme is to allow the medical research to shape our understanding of addictions in such a way that the physical aspects of the problem completely overshadow the spiritual aspects. The other extreme is to bury our head in the sand about the research being done on additions and to assert that addictions is only a spiritual (sin) issue that must be conquered with self control.
Addiction is a spiritual problem and it is a body (or brain based) problem. As Ed Welch says, addiction is a problem of disordered worship. And it is a brain based issue. Did you ever consider that not all patterns of sin involve the body/brain in the same way? For example, people don’t get high from gossiping or lying. And nobody develops a physical dependence on grumbling and then experiences withdrawal symptoms when he/she stops! There is something different about drug abuse that “hooks” the body in some way and we need to take that bodily component seriously if we are going to minister in a compassionate, truthful, and realistic way to those struggling with substance abuse.
It seems that alcohol and drugs of abuse hijack normal pathways in the brain associated with desire and pleasure. When you eat a sumptuous meal, listen to your favorite relaxing music, or engage in sexual activity leading to orgasm, your brain releases the neurotransmitter dopamine. It’s an elegant system and right in line with the psalmist’s declaration that we are fearfully and wonderfully made (Ps. 139:14). But drugs of abuse usurp the role of our brain’s natural neurotransmitter systems and lead to a much more explosive (and pleasurable) release of dopamine. Over time, it is hypothesized that the balance of dopamine changes, so that despite more frequent and higher amounts of the drug, there is less effect because the overall supply of dopamine decreases over time. And even with abstinence, it may take over a year to restore the natural balance.
What are a few counseling implications from this research?
As we have seen in this series of posts, attention to both the spiritual and bodily aspects of our personhood is essential for wise ministry. How have you seen this to be true with an addicted individual? Where have you seen imbalanced approaches that end up being detrimental to strugglers?
