Intervention Strengthens American Indian Teen Mothers’ Parenting

febrero del 2014

Teen mothers on three American Indian reservations improved on several measures of parenting after participating in Family Spirit, a home-visiting intervention developed with NIDA support. At 12 months postpartum, the women’s children exhibited reduced rates of emotional difficulties predicting later drug abuse and other behavioral problems. Infants at highest risk—those whose mothers had histories of drug abuse—benefited the most.

Prefrontal Cortex Stimulation Stops Compulsive Drug Seeking in Rats

enero del 2014

Researchers have shut down laboratory rats’ compulsive cocaine seeking by stimulating an area of the animals’ prefrontal cortex. The finding raises the possibility that stimulating neurons in this brain area may weaken or break cocaine’s grip on the behavior of people who are addicted to the drug.

Dr. Marilyn Huestis Q & A: Matching Drug Effects to Drug Concentrations

septiembre del 2013

Dr. Marilyn Huestis of NIDA’s Intramural Research Program talks about conducting research on drug effects with human subjects, developing tests to help law enforcement identify drugged drivers, and an assay to help identify children whose prenatal exposure to anti-HIV drugs may put them at risk for adverse developmental outcomes.

Male Rats’ Cocaine Exposure Affects Their Offspring’s Drug Responses

agosto del 2013

In a surprising finding, male rats who used cocaine sired male offspring who later exhibited blunted responses to the drug. Researchers determined the cause was an epigenetic alteration.

Study Pinpoints Cognitive Deficits Due to Cocaine, Finds Potential for Recovery

agosto del 2013

New research demonstrated that, in rhesus monkeys, ongoing cocaine exposure weakens two brain functions that people require for successful behavioral change: cognitive flexibility and memory. But the study determined that these changes may not be permanent.

Nicotine Makes Mouse Brain More Responsive to Cocaine

febrero del 2013

Nicotine sensitizes the mouse brain to the addictive effects of cocaine, according to recent NIDA-supported research. The results accord with the hypothesis that a person’s initial use of an addictive substance physiologically sensitizes his or her brain to the rewarding and addictive effects of other substances. If the findings carry over to people, then preventing youths from smoking might reduce their vulnerability to cocaine abuse and addiction, and cocaine-dependent individuals might ease their path to recovery by quitting smoking.

Animation: Building an Anti-Drug Vaccine

diciembre del 2012

The immune system has an extraordinary ability to recognize compounds foreign to the body and eliminate them. NIDA-sponsored scientists are working to harness this ability to create vaccines that will protect individuals against the psychogenic and addictive effects of abused drugs. This animation shows one of the most promising strategies, which has already yielded partial success in producing effective vaccines against nicotine, cocaine, and other drugs.

Stress Receptor Mediates Lifelong Consequences of Early Trauma

noviembre del 2012

NIDA-supported research suggests that glucocorticoid receptor levels during early brain development affect the hard wiring of neural circuits that shape an individual’s basic emotional makeup. In mice, overexpression of the glucocorticoid gene in the first weeks after birth increased anxiety and response to cocaine in adulthood. These findings may help researchers understand the genetic background and the developmental trajectory of addiction.
