A treatment that uses targeted magnetic pulses to the brain may reduce craving and substance use in people addicted to cocaine, a small study suggests.
A new study suggests smoking high-potency marijuana may cause damage to nerve fibers responsible for communication between the brain’s two hemispheres.
Long-term abuse of stimulant drugs such as cocaine and methamphetamine may have a greater effect on the brains of women compared with men who were dependent on the same drugs, a new study suggests.
Repeated exposure to alcohol during the teen years can lead to long-lasting changes in the part of the brain that controls memory and learning, a new study of rats suggests.
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.
Occasional marijuana use may change the brain structure in young adults, a new study suggests. Marijuana may cause changes related to motivation, emotion and reward.
Heavy marijuana use in the teenage years could damage brain structures vital to memory and reasoning, a new study suggests.
Long-term use of heroin appears to change how genes are activated in the brain, a new study suggests. This leads to changes in brain function, 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.
Disrupting memories of past drinking, by blocking a pathway in the brain linked to learning and memories, may help reduce alcoholic relapse, a study of rats suggests.
A new animal study suggests a missing brain enzyme increases concentrations of a protein related to opioid addiction, Science Daily reports.
Low doses of the active ingredient in marijuana appear to stop some forms of brain damage in mice, an Israeli researcher has found.
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.
People who drink heavily and smoke may have more signs of early aging of the brain, including problems with memory, quick thinking and problem solving, compared with heavy drinkers who are nonsmokers.
Exercise may help protect the brains of people who drink heavily, a new study suggests.
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.
A new study in rodents suggests that having a few drinks a day can adversely affect the brain.
Alcohol’s damaging effect on the brain can begin to subside two weeks after a person stops drinking, a new study suggests. Recovery may vary among different areas of the brain, the researchers say.
A decreased interest in food is associated with a greater interest in novelty-seeking behavior and cocaine use, a mouse study suggests.
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.
Ecstasy may produce long-lasting changes in brain chemistry, a new study suggests. The drug can cause a drop in the levels of the brain chemical serotonin for up to two years.
