Rutgers-Newark researchers link individual preferences to neuronal activity in brain
Based on research performed using laboratory rats, a team of neuroscience researchers at Rutgers University-Newark suggest that an intricate system exists within the brain for establishing individual preferences, which ultimately impacts choices. view more (2005-09-02)
Brain Scan Study Shows Cocaine Abusers Can Control Cravings
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. view more (2009-12-01)
Gene controlling circadian rhythms linked to drug addiction, UT Southwestern researchers find
The gene that regulates the body's main biological clocks also may play a pivotal role in drug addiction, researchers at UT Southwestern Medical Center have found. view more (2005-06-14)
'Erasing' drug-associated memories may stop drug addiction relapses
'Erasing' drug-associated memories may prevent recovering drug abusers from relapsing, researchers at the University of Cambridge have discovered. view more (2008-08-13)
The tachykinin receptor 3 gene has been linked to alcohol and cocaine dependence
The search for genes associated with alcohol dependence has recently been extended to the tachykinin receptor 3 gene, located within a broad region on chromosome 4q. Researchers have found that seven of the nine single nucleotide polymorphisms -- DNA sequence variations -- in the 3' region of TACR3 have a significant association with AD as well as... view more...

Evidence links cocaine abuse and Parkinson's disease
Adults who abuse cocaine might increase their risk of developing Parkinson's disease (PD), and pregnant women who abuse cocaine could increase the risk of their children developing PD later in life. view more (2005-12-13)
Increasing neurogenesis might prevent drug addiction and relapse
Researchers at UT Southwestern Medical Center hope they have begun paving a new pathway in the fight against drug dependence. Their hypothesis - that increasing the normally occurring process of making nerve cells might prevent addiction - is based on a rodent study demonstrating that blocking new growth of specific brain nerve cells increases... view more...

Studies find that 'broken heart syndrome' can result from opioid withdrawal, cocaine use
People who experience abrupt withdrawal from high-dose opioids or use cocaine increase their risk of cardiac event, according to two new studies published in the June issue of Mayo Clinic Proceedings. view more (2006-06-22)
Vaccines help kick drug habits
A pair of new vaccines designed to combat cocaine and methamphetamine dependencies not only relieve addiction but also minimize withdrawal symptoms. view more (2007-06-25)
Subordinate monkeys more likely to choose cocaine over food
Having a lower social standing increases the likelihood that a monkey faced with a stressful situation will choose cocaine over food, according to a study at Wake Forest University School of Medicine. More dominant monkeys undergoing the same stressful situation had fewer changes in brain activity in areas of the brain involved in stress and... view more... (2008-04-07)
Scientists design simple dipstick test for cocaine, other drugs
Researchers at the University of Illinois at Urbana-Champaign have developed a simple "dipstick" test for detecting cocaine and other drugs in saliva, urine or blood serum. view more (2006-11-14)
Altered perception of reward in human cocaine addiction
People addicted to cocaine have an impaired ability to perceive rewards and exercise control due to disruptions in the brain's reward and control circuits. view more (2006-10-16)
UCI neurobiologists find treatment to block memory-related drug cravings
A novel chemical compound that blocks memory-related drug cravings has the potential to be the basis of new therapies to aid drug-addiction recovery efforts, UC Irvine neurobiologists have found. view more (2005-09-19)
Why can't some people give up cocaine?
Drug dependency is a recurrent but treatable kind of addiction. However, not all people who are drug dependent progress in the same way once they stop taking drugs. view more (2009-11-20)
Research offers new approach to developing treatments for cocaine and amphetamine addiction
The study shows that highly addictive drugs, like cocaine and amphetamine, require a neurotransmitter called CART (Cocaine- and Amphetamine-Regulated Transcript) peptides to produce their maximal effects. view more (2005-09-29)
Portable cocaine sensor developed at UC Santa Barbara
A real-time sensor for detecting cocaine -- made with inexpensive, off-the-shelf electronics -- has been developed by a team of researchers at the University of California, Santa Barbara. view more (2006-02-27)
Cocaine: How addiction develops
Permanent drug seeking and relapse after renewed drug administration are typical behavioral patterns of addiction. Molecular changes at the connection points in the brain's reward center are directly responsible for this. view more (2008-08-22)
Do recreational drugs make us fail to remember?
Have you ever forgotten to post an important letter or let an appointment slip your mind? A new study from UK researchers suggests that for those who regularly use ecstasy or other recreational drugs, this kind of memory lapse is more common. view more (2010-02-24)
Study reveals biochemical signature of cocaine craving in humans
Using sophisticated brain-imaging techniques at the U.S. Department of Energy's Brookhaven National Laboratory, scientists from the National Institute on Drug Abuse (NIDA), Brookhaven Lab, and the University of Pennsylvania have uncovered the brain chemistry that underlies such "cue-induced" craving in cocaine addicts. view more (2006-06-14)
Halting retrieval of drug-associated memories may prevent addiction relapse
Disrupting the brain's retrieval of drug-associated memories may prevent relapse in drug addiction, according to new research in the August 13 issue of The Journal of Neuroscience. view more (2008-08-13)
