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.
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.
Researchers at Johns Hopkins have unraveled the molecular foundations of cocaine's effects on the brain, and identified a compound that blocks cravings for the drug in cocaine-addicted mice.
By stimulating one part of the brain with laser light, researchers at the National Institutes of Health (NIH) and the Ernest Gallo Clinic and Research Center at UC San Francisco (UCSF) have shown that they can wipe away addictive behavior in rats - or conversely turn non-addicted rats into compulsive cocaine seekers.
Could drug addiction treatment of the future be as simple as an on/off switch in the brain? A study in rats has found that stimulating a key part of the brain reduces compulsive cocaine-seeking and suggests the possibility of changing addictive behavior generally.
A Wake Forest Baptist Medical Center team studying alcohol addiction has new research that might shed light on why some drinkers are more susceptible to addiction than others.
Scientists have discovered a molecular process in the brain triggered by cocaine use that could provide a target for treatments to prevent or reverse addiction to the drug.
All too often, stress turns addiction recovery into relapse, but years of basic brain research have provided scientists with insight that might allow them develop a medicine to help. A new study in the journal Neuron pinpoints the neural basis for stress-related relapse in rat models to an unprecedented degree.
Disulfiram was the first medication approved for the treatment of alcoholism over 50 years ago. It works, at least in part, by preventing the metabolism of an alcohol by-product, acetaldehyde. High levels of acetaldehyde in the body quickly cause unpleasant symptoms, including nausea, vomiting, headache, and accelerated heart rate. Thus, disulfiram provides a very strong incentive to avoid drinking.
Researchers from the University of Wisconsin-Milwaukee (UWM) have identified mechanisms in the brain responsible for regulating cocaine-seeking behavior, providing an avenue for drug development that could greatly reduce the high relapse rate in cocaine addiction.
Mental illnesses and addictions take more of a toll on the health of Ontarians than cancer or infectious diseases, according to a new report by the Institute for Clinical Evaluative Sciences and Public Health Ontario - yet this burden could be reduced with treatment, say scientists from Canada's Centre for Addiction and Mental Health.
Chronic morphine exposure has the opposite effect on the brain compared to cocaine in mice, providing new insight into the basis of opiate addiction, according to Mount Sinai School of Medicine researchers. They found that a protein called brain-derived neurotrophic factor (BDNF), which is increased in cocaine addiction, is inhibited in opioid addiction. The research is published in the October 5 issue of Science.
Chronic morphine exposure has the opposite effect on the brain compared to cocaine in mice, providing new insight into the basis of opiate addiction, according to Mount Sinai School of Medicine researchers.
This is a set of malignancies that arise in germ cells of the testicles, the specialized cells that produce sperm. Taken together, testicular cancers are the most common form of malignancy that occurs in young men (approximately 15 to 35 years of age).
The party drug mephedrone can cause lasting damage to the brain, according to new research led by the University of Sydney.
A "contingency management" approach—offering incentives for negative drug tests—can help promote drug abstinence among pregnant women with heroin or cocaine addiction, reports a study in the September Addictive Disorders & Their Treatment. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
A combination of two existing pharmaceutical drugs may soon be used to treat cocaine addiction, findings from an animal study in Science Translational Medicine suggest.
A fine-tuned combination of two existing pharmaceutical drugs has shown promise as a potential new therapy for people addicted to cocaine—a therapy that would reduce their craving for the drug and blunt their symptoms of withdrawal.
Cigarette smoking and nicotine addiction are widespread problems throughout the world. Many people continue to smoke despite high taxes and the available public information on the dangers of smoking.
A single-dose vaccine capable of providing immunity against the effects of cocaine offers a novel and groundbreaking strategy for treating cocaine addiction is described in an article published Instant Online in Human Gene Therapy, a peer-reviewed journal from Mary Ann Liebert, Inc.
Chronic exposure to cocaine reduces the expression of a protein known to regulate brain plasticity, according to new, in vivo research on the molecular basis of cocaine addiction. That reduction drives structural changes in the brain, which produce greater sensitivity to the rewarding effects of cocaine.
