Cocaine Addiction News and Research

RSS

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.

Study shows relationship between cocaine-induced brain deficits in prefrontal cortex and cocaine-seeking

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.

Scientists pinpoint neural basis for stress-related relapse in rat models

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.

Study supports hypothesis that disulfiram reduces drug consumption by blocking DβH

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 identify brain mechanisms that regulate cocaine-seeking behavior

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.

Addiction and mental health burden higher than all cancers in Ontario

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.

Morphine inhibits BDNF protein, whereas cocaine enhances BDNF

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.

Marijuana and testicular cancer: an interview with Victoria Cortessis

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).

Incentives can help promote drug abstinence among pregnant women with heroin or cocaine addiction

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.

Two-drug combination helps combat cocaine addiction

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.

Combination of two existing pharmaceutical drugs shows promise against cocaine addiction

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.

Single-dose vaccine for treatment of cocaine addiction

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 drives structural changes in the brain

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.

Study shows how cocaine changes the shape and size of neuron rewards in mouse model

New research from Mount Sinai Medical Center in New York reveals that repeated exposure to cocaine decreases the activity of a protein necessary for normal functioning of the brain's reward system, thus enhancing the reward for cocaine use, which leads to addiction. Investigators were also able to block the ability of repeated cocaine exposure, to induce addiction.

Scientists reveal first-ever glimpse of complete kappa opioid receptor structure

At the molecular level, drugs like salvinorin A (the active ingredient of the hallucinogenic plant Salvia divinorum) work by activating specific proteins, known as receptors, in the brain and body.

“Meth” babies more at risk of behavioral problems: Study

A new study shows methamphetamine's potential lasting behavioral effects on kids of mothers who used meth during pregnancy. The behavior differences — anxiety, depression, moodiness — weren't huge, but lead researcher Linda LaGasse called them “very worrisome.”
