Why Cocaine Addicts Keep Making Bad Decisions
Chronic cocaine use alters brain circuits that help us learn from mistakes, a new study suggests. The study, published online Tuesday in the Journal of Neuroscience, could offer a biological marker for the cycle of destructive decisions that many addicts exhibit. This could explain why addicts will return to drugs despite the negative impacts of incarceration and loss of money, friends and family, according to the researchers. "They don't learn from it," said the study's lead researcher, Muhammad Parvaz, a cognitive neuroscientist at the Icahn School of Medicine at Mount Sinai in New York.
