Cocaine dependence (or addiction) is physical and psychological dependency on the regular use of cocaine. It can result in severe physiological damage, psychosis, schizophrenia, lethargy, depression, or a potentially fatal overdose.
A long-acting enzyme that rapidly and safely metabolizes cocaine in the blood stream is currently being investigated in animal models as a possible treatment for cocaine overdose.
Abstinence is the best way to avoid drug addiction. But in many societies, drug use is the norm, not the exception, especially by youth.
Researchers at the University at Buffalo have discovered a previously unknown neural pathway that can regulate changes made in the brain due to cocaine use, providing new insight into the molecular basis of cocaine addiction.
One of the major challenges of cocaine addiction is the high rate of relapse after periods of withdrawal and abstinence. But new research reveals that changes in our DNA during drug withdrawal may offer promising ways of developing more effective treatments for addiction.
The brain function of people addicted to cocaine is different from that of people who are not addicted and often linked to highly impulsive behavior, according to a new scientific study.
Researchers at the University of Copenhagen have gained new insight into the mechanism behind a protein dopamine transporter that could help in the development of future medical treatment against cocaine addiction.
Women are more sensitive to the effects of cocaine and more susceptible to cocaine abuse than men. Cocaine's ability to disrupt a woman's estrus cycle may explain the sex differences in cocaine addiction, and new evidence that caffeine may be neuroprotective and able to block cocaine's direct effects on the estrus cycle reveals novel treatment possibilities, according to an article published in Journal of Caffeine Research: The International Multidisciplinary Journal of Caffeine Science, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.
A study led by investigators from Massachusetts General Hospital and the Perelman School of Medicine at the University of Pennsylvania has identified a potential target for therapies to treat cocaine addiction.
Virginia Commonwealth University has received a five-year, $6 million grant for clinical research and education directed toward the identification, evaluation and development of safe and effective treatments for cocaine addiction.
The National Institutes of Health has turned to neuroscientists at the nation's most "Stone Cold Sober" university for help finding ways to treat drug and alcohol addiction.
A group of 11 genes can successfully predict whether an individual is at increased risk of alcoholism, a research team from the United States and Germany reported Tuesday.
The National Institute on Drug Abuse has awarded a five-year, $6.6 million grant to the University of Texas Medical Branch at Galveston to establish the Translational Addiction Sciences Center. The center will investigate the mechanisms underlying addiction with the goal of discovering and validating novel treatment options.
A novel compound that targets an important brain receptor has a dramatic effect against a host of cocaine addiction behaviors, including relapse behavior, a University at Buffalo animal study has found.
In Europe as well as worldwide, cocaine is the second most frequently used drug after cannabis. Chronic cocaine users display worse memory performance, concentration difficulties, and attentional deficits but also their social skills are affected as previous studies at the Psychiatric Hospital of the University of Zurich suggested.
Researchers from the Icahn School of Medicine at Mount Sinai have identified a new molecular mechanism by which cocaine alters the brain's reward circuits and causes addiction.
Imagine kicking a cocaine addiction by simply popping a pill that alters the way your brain processes chemical addiction. New research from the University of Pittsburgh suggests that a method of biologically manipulating certain neurocircuits could lead to a pharmacological approach that would weaken post-withdrawal cocaine cravings. The findings have been published in Nature Neuroscience.
Magnetic resonance imaging provides a noninvasive way to measure iron levels in the brains of people with attention deficit hyperactivity disorder, according to a study being presented today at the annual meeting of the Radiological Society of North America. Researchers said the method could help physicians and parents make better informed decisions about medication.
A team of researchers says it has solved the longstanding puzzle of why a key protein linked to learning is also needed to become addicted to cocaine. Results of the study, published in the Aug. 1 issue of the journal Cell, describe how the learning-related protein works with other proteins to forge new pathways in the brain in response to a drug-induced rush of the “pleasure” molecule dopamine.
A single dose of a commonly-prescribed attention deficit hyperactivity disorder drug helps improve brain function in cocaine addiction, according to an imaging study conducted by researchers from the Icahn School of Medicine at Mount Sinai.
Scientists at The Scripps Research Institute (TSRI) have found evidence that an emotion-related brain region called the central amygdala—whose activity promotes feelings of malaise and unhappiness—plays a major role in sustaining cocaine addiction.
