Link between emotional impairment and poor cognition in children with bipolar disorder

Using functional magnetic resonance imaging, Pavuluri and her colleagues examined the brain activity of teens while they were performing certain mental tasks. The researchers scanned the brains of 10 unmedicated bipolar patients with normal mood and compared them with 10 healthy subjects of the same age and gender.

Research reveals possible mechanisms for the treatment of cocaine addiction

Researchers are now understanding in greater detail the molecular machinery underlying the short-term brain changes that produce the high of cocaine, as well as the longer-term changes behind addiction. Their findings offer hope for targeted drugs that can short-circuit that addiction machinery.

Long-term smoking linked to diminished mental proficiency

The association between long-term smoking and diminished mental proficiency in 172 alcoholic and non-alcoholic men was a surprising finding from a study that set out to examine alcoholism's long-term effect on the brain and thinking skills.

Association between long-term smoking and diminished mental proficiency

Smokers often say that smoking a cigarette helps them concentrate and feel more alert. But years of tobacco use may have the opposite effect, dimming the speed and accuracy of a person’s thinking ability and bringing down their IQ, according to a new study led by University of Michigan researchers.

Evaluation of the efficacy of buprenorphine hydrochloride and clonidine hydrochloride, in detoxification of opioid-dependent teenagers

In a comparison of two drugs prescribed to treat teenagers dependent on heroin and other opioids, the drug buprenorphine was more effective, especially in treatment retention, according to a study in the October issue of Archives of General Psychiatry.

New light shed on the causes of drug addiction

A methamphetamine epidemic rages across the United States with addicts blinded by uncontrollable desires for a drug that eventually thrusts them into a dire and catastrophic existence. Doctors don't have any effective treatments for these addicts, or for any other drug addicts; drug addiction is a disease that remains a medical mystery.

Nicotine has an unusual psychological property that may drive dependence

Associate Professor Athina Markou, Ph.D., who is in the Scripps Research Molecular and Integrative Neurosciences Department at Scripps Research’s La Jolla Campus, and Paul Kenny, Ph.D., a former Research Associate in her laboratory, report in an upcoming issue of the journal Neuropsychopharmacology that nicotine has an unusual psychological property that may drive dependence.

Possibility of tailored treatments for addiction based on how a person's genes behave

Scientists have learned how a genetic variation long suspected in making some people susceptible to alcoholism and narcotic drug addiction actually does so.

First step towards effective drug-addiction therapies

A novel chemical compound that blocks memory-related drug cravings has the potential to be the basis of new therapies to aid drug-addiction recovery efforts, UC Irvine neurobiologists have found.

HDL cholesterol helps prevent blocked arteries and heart attack

Cardiology experts at Johns Hopkins have issued interim guidelines for physicians on how best to treat low levels of HDL cholesterol, the so-called good cholesterol, which helps keep arteries clear from the buildup of LDL cholesterol, the so-called bad cholesterol.

Key neural system at risk from prenatal exposure to alcohol

In a study of adult monkeys who were exposed to moderate amounts of alcohol in utero, scientists have found that prenatal exposure to alcohol - even in small doses - has pronounced effects on the development and function later in life of the brain's dopamine system, a critical component of the central nervous system that regulates many regions of the brain.

Enhanced imaging techniques could improve medical diagnosis

Chris Wyatt is a Virginia Tech electrical engineer who is attempting to provide the medical community with better, quicker, and more relevant images of the human body. The side effects are not bad either - lower medical costs, new treatments, and earlier disease detection.

46,000 crack cocaine users aged 15-44 in London

Researchers believe there could be 46,000 crack cocaine users aged 15-44 in London, suggesting one in every hundred young adult Londoners could be a user.

Researchers selectively knock out memory associations connected with receiving cocaine

Addicts crave drugs and suffer relapse not just because of the alluring high of drugs, but also because they are compelled by the powerful, haunting memory associations with the environment surrounding their drug taking. Thus, treatments that could eliminate those memory associations could prove effective in treating addiction, researchers believe.

Genetic basis for susceptibility to alcohol abuse confirmed

A new set of experiments in mice confirms that a brain receptor associated with the reinforcing effects of marijuana also helps to stimulate the rewarding and pleasurable effects of alcohol.

Stress leads to drugs, leads to more stress and more drugs - part of a vicious cycle

According to a new Australian study, opiate drugs such as morphine have been found to leave animals more vulnerable to stress, and this could mean stress and opiates are caught in a vicious cycle.

Opiate drugs such as morphine leave animals more vulnerable to stress

A new study has found that opiate drugs such as morphine leave animals more vulnerable to stress. This means that stress and opiates are in a vicious cycle: Not only does stress trigger drug use, but in return the drug leaves animals more vulnerable to stress.

Teenage drug use can lead to adult addiction and heart attack

A new study from the Howard Florey Institute in Melbourne may help explain why people who experimented with amphetamines, such as 'speed', as teenagers are more likely to become addicted and more susceptible to heart attack following re-use of the drug as adults.

Depressant benzodiazepine especially effective at treating seizure in alcohol withdrawal syndrome patients

Tranquilizers work better than placebos at treating the symptoms of alcohol withdrawal syndrome but they may not work better than other drugs, according to a new review of recent studies.

Neurotransmitter orexin influences reward processing - associated with pleasure and reward pathways in the brain

Researchers at the University of Pennsylvania School of Medicine have discovered that the recently identified neurotransmitter orexin (also known as hypocretin) influences reward processing by activating neurons in the lateral hypothalamus region of the brain.
