New Addiction Research Suggests Genes Play a Factor
Recently, the U.S. Department of Energy’s Brookhaven National Laboratory completed an addiction research study focused on genes. The study found that genetics may be a factor in substance dependency. In fact, addicted individuals that have a specific genetic composition have fewer neurons in some regions of their brains. Those addicted to drugs have fewer neurons in the areas responsible for decision making, self-control, learning, and memory. So, depending on genetics, any given person may or may not be susceptible to addiction development.
“This research shows that genes can influence the severity of addiction,” said Nelly Alia-Klein, an author of the research study. “[It] shows that genes can influence the severity of addiction.” In the study, scientists examined the role of the monoamine oxidase A genotype in addiction. Interestingly, the results suggest that addicted individuals with low MAOA may need a different kind of treatment than [those] who carry the high MAOA genotype.
While theBrookhaven National Laboratory headed the study, they were not the only ones involved. In fact, the research study was a combined effort of scientists all over the country. Contributors include Brookhaven National Laboratory, Stony Brook University, Mount Sinai School of Medicine, NIAAA, and NIDA.
