A new study in rats suggests heavy drinking during the teen years could lead to structural changes in the brain that last into adulthood. The changes occur in the region of the brain important in reasoning and decision-making.
Teenagers who experience a traumatic brain injury are at increased risk of using marijuana, drinking alcohol and smoking, a new study finds. They are also at risk of getting poor grades, HealthDay reports.
People who are both smokers and heavy drinkers have a faster decline in brain function, compared with those who don’t smoke and who drink moderately, a new study suggests. Smoking and heavy drinking is associated with a 36 percent quicker decline in cognitive function.
Scientists at Johns Hopkins University have identified a compound that stopped mice addicted to cocaine from wanting the drug. The compound has been proven safe for humans and is undergoing further animal testing, in preparation for possible clinical trials for people addicted to cocaine.
The shape of cocaine users’ brains may influence whether they become addicted to the drug, British researchers have found. A smaller frontal lobe is associated with a greater risk of cocaine addiction.
Poor impulse control may be pre-wired in some teenagers, suggests a new study. Researchers have identified brain networks that are linked to impulse control and drug addiction, which may exist even before someone is exposed to alcohol or drugs.
Chronic cocaine use may accelerate aging of the brain, a new study suggests. The study found people with cocaine dependence have greater levels of age-related loss of nerve tissue in the brain called gray matter.
Middle-aged male smokers experience a faster decline in brain function compared with men who never smoked, a new study finds. Decline in brain function among men who quit 10 years ago is similar to that seen in men who never smoked.
