Special issue of Neuron examines the new neuroscience of substance abuse Addiction is a brain disease that destroys lives, devastates families and tears at the very fabric of society. Effective prevention and treatment of addiction requires a clear understanding of the complex brain mechanisms that underlie addictive behaviors, and research has provided a fascinating view of how substance abuse hijacks neuronal circuits involved in reward and motivation and causes profound and persistent...

Speaking directly into a cellphone while holding it against your ear can alter brain activity in those areas closest to the device's antenna, claims a new study published Tuesday in the Journal of the American Medical Association (JAMA). Researchers at the National Institutes of Health (NIH) and the Brookhaven National Laboratory in New York studied 47 adults over the course of a year, using positron emission tomography (PET) to measure their glucose metabolism, or the amount of sugar it...

Researchers at the U.S. Department of Energy's Brookhaven National Laboratory have developed an imaging protocol that allows them to visualize the activity of the brain's reward circuitry in both normal individuals and those addicted to drugs. The technique could lead to better insight into why people take recreational drugs as well as help determine which treatment strategies might be most effective. Drug addiction is a complex process that involves numerous biological and environmental...

New treatments aimed at strengthening inhibitory control could help prevent relapse When asked to inhibit their response to a "cocaine-cues" video, active cocaine abusers were, on average, able to suppress activity in brain regions linked to drug craving, according to a new study at the U.S. Department of Energy's Brookhaven National Laboratory. The results, to be published in an upcoming issue of NeuroImage, suggest that clinical interventions designed to strengthen these inhibitory...

The new weapon in the war on drug and nicotine addiction may soon come in the form of a vaccine. Dr. Nora Volkow, director of the National Institute on Drug Abuse, told reporters that the Institute intends to convince drug companies that a vaccine for drug and nicotine addiction would be successful. "There is an enormous amount of research and development in vaccines for cancers and a wide variety of disorders," she said at the Society for Neuroscience meeting in Chicago. "We can take...

In the first successful study of a vaccination approach to treating drug addiction, a vaccine that uses the immune system to help block the euphoric effects of cocaine had a promising effect among 38 percent of subjects who received it, according to a Baylor College of Medicine researcher who headed the study. While the shots did not have a perfect effect, the researchers believe the small success is promising enough to indicate that the new vaccine approach could be widely used to treat...

Low levels of dopamine markers may underlie symptoms; implications for treatment A brain-imaging study conducted at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory provides the first definitive evidence that patients suffering from attention deficit hyperactivity disorder (ADHD) have lower-than-normal levels of certain proteins essential for experiencing reward and motivation. "These deficits in the brain's reward system may help explain clinical symptoms of ADHD,...

A small government study suggests that the narcolepsy drug modafinil "” a so-called "smart drug" increasingly being used to enhance cognitive abilities "” may be more addictive than doctors thought, the Associated Press reported. A study involving 10 healthy men found that the prescription drug Provigil (generic name: Modafinil) caused changes in the brain's pleasure center, very much like potentially habit-forming classic stimulants. College students often use Modafinil as an...
