Understanding Drug Addiction as a Disease
Drug addiction is a disease. There’s no doubt about that. In fact experts say that drug addiction is more of a brain disease than anything else. Scientific advances have offered amazing insights into how the brain works and what drugs do to the way the brain functions. Luckily, however, this disease is treatable and curable.
Although drug use initially is voluntary once an addiction develops, that control is markedly changed. Imaging studies have shown specific abnormalities in the brains of some, but not all, addicted individuals. While scientific advancements in the understanding of addiction have occurred at unprecedented speed in recent years, unanswered questions remain that highlight the need for further research to better define the neurobiological processes involved in addiction.
Recent studies have increased our knowledge of how drugs affect gene expression and brain circuitry, and how these factors affect human behavior. They have shed new light on the relationship between drug abuse and mental illness, and the roles played by heredity, age, and other factors in increased vulnerability to addiction. New knowledge from future research will guide new strategies and change the way clinicians approach the prevention and treatment of addiction.
