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.
Chemical changes caused by cocaine may be passed on to the next generation, a new study of rats suggests. The changes cause male offspring to find the drug less rewarding.
