Chronic Cocaine Use Triggers Changes In Brain's Neuron Structure
2012-05-09 14:26:44

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. The finding suggests a potential new target for development of a treatment for cocaine addiction. It was published last month in Nature Neuroscience by researchers at the University at...

(Ivanhoe Newswire)-- The United Nations Office on Drugs and Crime estimates that cocaine is used by up to 21 million individuals worldwide, with approximately 1 per cent of these individuals becoming dependent. Now, a new study shows that frequent cocaine abuse can lead to accelerated aging of the brain. Cocaine is a strong central nervous system stimulant that increases levels of dopamine, a brain chemical associated with pleasure and movement, in the brain´s reward circuit. The...

Research shows chronic users' brains age dramatically faster than their non-drug-using peers New research by scientists at the University of Cambridge suggests that chronic cocaine abuse accelerates the process of brain aging. The study, published today 25 April in Molecular Psychiatry, found that age-related loss of grey matter in the brain is greater in people who are dependent on cocaine than in the healthy population. For the study, the researchers scanned the brains of 120 people...

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. The findings, published online April 22 in the journal Nature Neuroscience, provide the first evidence of how cocaine changes the...

Possible Antidote For Cocaine Overdose Emerges
2012-04-19 06:51:26

Connie K. Ho for RedOrbit.com Found in more than 400,000 emergency room visits and related to 5,000 overdose deaths a year in the United States, cocaine is a highly dangerous drug that can lead to death. Scientists at the Scripps Institute of Research decided to tackle this issue head on with a study that examines a solution that can be injected to reverse the effects of cocaine overdose in emergency situations. With the solution´s success in trials with mice, the researchers hope to...
