Europe to tackle brain disorder research by linking industry, academia
Attempts to cure brain-related disorders have proved less successful than therapies for other major conditions such as heart cancer, even though just as many people suffer from them. view more (2007-11-28)
A pioneering study opens roads for tailor-made antidepressants
In spite that the causes of depression have not still been fully identified, scientists acknowledge that genetic and environmental factors play a common role in the onset of this disorder. view more (2007-08-06)
Ecstasy can harm the brains of first-time users
Researchers have discovered that even a small amount of MDMA, better known as ecstasy, can be harmful to the brain, according to the first study to look at the neurotoxic effects of low doses of the recreational drug in new ecstasy users. view more (2006-11-28)
UBC researchers develop new method to study gambling addictions
UBC researchers have created the world's first animal laboratory experiment to successfully model human gambling. view more (2009-06-17)
Research leads to healthful strategies for re-setting the body's clock
Everyone is equipped with a biological clock, a region in the brain the size of a corn kernel, which dictates our sleep-wake cycles, and plays a major role in our physical and mental health. view more (2006-03-23)
Switching medications, adding psychotherapy may help teens with ineffective depression medication
For adolescents with depression not responding to an initial treatment with a selective serotonin reuptake inhibitor (SSRI; a class of antidepressant drugs), switching medications and adding cognitive behavioral therapy resulted in an improvement in symptoms, compared to just changing medications. view more (2008-02-27)
Some nonhormonal therapies may offer relief from hot flashes, but with possible adverse effects
A meta-analysis of previously published studies examining the use of nonhormonal therapies for treating menopausal hot flashes finds that some therapies are effective, but less so than estrogen, and have possible adverse effects that may restrict their use. view more (2006-05-03)
Deafness and seizures result when mysterious protein deleted in mice
Scientists have discovered that mice genetically engineered to lack a particular protein in the brain have profound deafness and seizures. The finding suggests a pathway, they say, for exploring the hereditary causes of deafness and epilepsy in humans. view more (2008-01-25)
Studies assess effectiveness of serotonin and nerve stimulants on irritable bowel syndromes
Studies have shown that gastrointestinal (GI) tract function is often influenced by specific stimulants or reactors, which sometimes cause irritable bowel syndrome (IBS) or constipation. view more (2007-05-22)
New treatment mechanisms for schizophrenia
The field of schizophrenia research has come alive with many exciting new potential approaches to treatment. From the introduction of chlorpromazine to the current day, all treatments approved by the U.S. Food and Drug Administration have had, at their core, a single treatment mechanism, the blockade of the dopamine D2 receptor. view more (2008-01-09)
High anxiety?
Right now, about half of all people who take medicine for an anxiety disorder don't get much help from it. And doctors have no definitive way to predict who will, and who won't, benefit from each anti-anxiety prescription they write. view more (2008-04-21)
Study reveals possible genetic risk for fetal alcohol disorders
New research in primates suggests that infants and children who carry a certain gene variant may be more vulnerable to the ill effects of fetal alcohol exposure. view more (2007-09-24)
Can Anti-Depressant Drugs Induce Suicidality? The Controversy Continues
The publication of an article by North Wales psychiatry David Healy in Psychotherapy and psychosomatics (March-April 2003) on the relationship between Selective Serotonin Reuptake Inhibitors (SSRI) and suicidal risk sparked a heated debate. Such debate paved the way for the banning of paroxetine in children and adolescents in UK and US. Now, in... view more... (2003-10-22)
Success or failure of antidepressant citalopram predicted by gene variation
A variation in a gene called GRIK4 appears to make people with depression more likely to respond to the medication citalopram (Celexa) than are people without the variation, a study by the National Institute of Mental Health (NIMH), part of the National Institutes of Health, has found. view more (2007-08-01)
Millisecond brain signals predict response to fast-acting antidepressant
Images of the brain's fastest signals reveal an electromagnetic marker that predicts a patient's response to a fast-acting antidepressant, researchers have discovered. view more (2008-10-03)
New Tools Developed for Studying Neurodegenerative Brain Disorders
Penn State researchers have created an elegantly simple model of an axon-the extension of a neuron that communicates with other neurons-and have used this model to reproduce a change in the axon's shape that is characteristic of neurodegenerative disorders such as Alzheimer's and Parkinson's diseases. view more (2006-03-22)
Team identifies a molecular switch linking infectious disease and depression
Researchers at the University of Illinois report that IDO, an enzyme found throughout the body and long suspected of playing a role in depression, is in fact essential to the onset of depressive symptoms sparked by chronic inflammation. view more (2009-04-01)
Cocaine's effects on brain metabolism may contribute to abuse
Many studies on cocaine addiction - and attempts to block its addictiveness - have focused on dopamine transporters, proteins that reabsorb the brain's "reward" chemical once its signal is sent. view more (2008-02-19)
