A French medical researcher claims that moderate caffeine consumption does not lead to addiction, but rather increases alertness and energy. However, high doses of caffeine can trigger functional activity in the brain's reward system, leading to potential negative effects such as anxiety and depression.
Researchers mapped brain regions affected by cocaine and found that addiction is linked to the right side of the brain. The study used a powerful brain-imaging technique to map frontal-lobe regions associated with cocaine's effects in 20 cocaine addicts.
A new Johns Hopkins study suggests better ways of taking LAAM, a drug similar to methadone, by increasing dosage frequency and reducing side effects. The study found significant reductions in heroin use among participants, with over 80% staying with the treatment, and increased patient adherence due to its longer-acting benefits.
The National Institute on Drug Abuse (NIDA) is hosting a two-day national conference to discuss the latest scientific research on nicotine addiction. The conference will highlight the behavioral and neurobiological bases of nicotine addiction, as well as state-of-the-art treatment strategies and prevention methods.
A study discovered that individuals carrying a genetic variant in the CYP2A6 enzyme break down nicotine more slowly, leading to greater resistance to nicotine addiction. This finding suggests that medications targeting the enzyme may help prevent and treat nicotine addiction.
A study by INFORMS shows that introducing difficult-to-reuse syringes, also known as DTRs, into the current needle population does not reduce HIV rates among addicts. In fact, it increases the risk of exposure to infectious needles due to increased reuse of regular syringes.
The center will bring together leading cellular and molecular neuroscientists to focus on addiction from an interdisciplinary approach. It aims to understand how addicting drugs act on receptors and disrupt normal communication between nerve cells in the brain, with the ultimate goal of finding new therapeutic approaches for addiction.
Researchers at Emory University have synthesized a compound called RTI-113 that targets the same dopamine transporters as cocaine, with potential to treat addiction and eating disorders. The medication reduces self-administration in monkeys and shows promise in managing urge for 'out-of-control' drug-seeking behaviors.
The study uses fMRI to map brain activity in response to cocaine, revealing a broader range of brain structures involved than previously thought. The nucleus accumbens and amygdala play key roles in the reward system, with the former associated with reinforcement and the latter with incentive.
Researchers at Johns Hopkins Medicine have discovered a protein called Homer that strengthens the link between drug addiction and long-term memory. The study found that Homer binds to nerve cells' message-receiving structures, potentially leading to new treatments for addiction.
The Brookhaven National Lab has been named a Drug Addiction Study Center, focusing on brain chemistry and imaging techniques to develop new treatments. Research will study cocaine, heroin, nicotine, tobacco, alcohol, and marijuana, aiming to understand the biological bases of addiction.
