Is There a Biological Basis for Addiction?
Yes! Addiction is complex and involves many types of social, biological, and psychological factors but it is a highly heritable. About 50% of the risk for an addiction is genetic. For those without the genetic heritability, addiction involves changes in many brain structures that increase the behavioral components of addition.
Drugs, alcohol, food and even shopping can hijack the pleasure or reward circuits in your brain and hook the addict into wanting more and more. In addition, repeated use of a vice can damage the essential decision-making center at the front part of the brain making you more likely to continue using. Addiction is a devastating disease that can impact any individual or family.
