Study points to new uses, unexpected side effects of already-existing drugs
Scientists at the University of North Carolina at Chapel Hill School of Medicine and the University of California, San Francisco have developed and experimentally tested a technique to predict new target diseases for existing drugs. view more (2009-11-04)
Stress-induced changes in brain circuitry linked to cocaine relapse
Stress-evoked changes in circuits that regulate serotonin in certain parts of the brain can precipitate a low mood and a relapse in cocaine-seeking, based on mouse studies published online this week in the Proceedings of the National Academy of Sciences. view more (2009-10-30)
Hunting for the Prozac Gene
Prozac works wonders for some depressed people, but not for others. In some cases, patients derive little benefit and at worst, it can lead to bizarre hallucinations and fits of rage. view more (2009-10-28)
'Culture of we' buffers genetic tendency to depression
A genetic tendency to depression is much less likely to be realized in a culture centered on collectivistic rather than individualistic values, according to a new Northwestern University study. view more (2009-10-28)
Study reveals an increase in long-term antidepressant drug use
A dramatic rise in antidepressant prescriptions issued by GPs has been caused by a year on year increase in the number of people taking antidepressant drugs on a long-term basis, according to researchers from the University of Southampton. view more (2009-10-23)
Fine-tuning treatments for depression
New research clarifies how neurotransmitters like norepinephrine, serotonin, and dopamine, are regulated - a finding that may help fine-tune therapies for depression. view more (2009-10-19)
Popular antidepressant associated with a dramatic increase in suicidal thoughts amongst men
Nortriptyline has been found to cause a ten-fold increase in suicidal thoughts in men when compared to its competitor escitalopram. These findings are published in the open access journal BMC Medicine. view more (2009-10-15)
Why one way of learning is better than another
A new study from the Montreal Neurological Institute and Hospital (The Neuro) of McGill University reveals that different patterns of training and learning lead to different types of memory formation. view more (2009-10-02)
Researchers identify new brain pathway for regulating weight and bone mass
Contrary to the prevailing view, the hormone leptin, which is critical for normal food intake and metabolism, appears to regulate bone mass and suppress appetite by acting mainly through serotonin pathways in the brain. view more (2009-09-24)
UCLA scientists make paralyzed rats walk again after spinal-cord injury
UCLA researchers have discovered that a combination of drugs, electrical stimulation and regular exercise can enable paralyzed rats to walk and even run again while supporting their full weight on a treadmill. view more (2009-09-21)
New method can predict 80 percent of cases of postnatal depression
Worldwide, 13% of women who give birth suffer from postnatal depression, which causes a significant deterioration in a mother's quality of life and her ability to care for her baby. view more (2009-09-17)
Are the monoamines involved in shaping conduct disorders?
Antisocial and aggressive behaviours represent a widespread and expensive social problem. Recent research has convincingly shown that there is a strong interaction between genetic inheritance and environment for development of personality and behaviour. view more (2009-09-14)
Antidepressants: benefit of SNRI is proven
The Institute for Quality and Efficiency in Health Care (IQWiG) was commissioned by the Federal Joint Committee (G-BA) to investigate whether patients with depression benefit from taking drugs belonging to the selective serotonin and norepinephrine reuptake inhibitor (SNRI) drug class. view more (2009-08-26)
Genetic marker linked to problem behaviors in adults with developmental disabilities
A common variation of the gene involved in regulating serotonin and norepinephrine in the brain may be linked to problem behaviors in adults with developmental and intellectual disabilities, new research indicates. view more (2009-07-22)
Tryptophan deficiency may underlie quinine side effects
Researchers have found that the anti-malarial drug quinine can block a cell's ability to take up the essential amino acid tryptophan, a discovery that may explain many of the adverse side-effects associated with quinine. view more (2009-06-29)
Lack of happiness hormone serotonin in the brain causes impaired maternal behavior in mice
A lack of serotonin, commonly known as the "happiness hormone", in the brain slows the growth of mice after birth and is responsible for impaired maternal behavior later in life. view more (2009-06-24)
Larvae shun the light
Drosophila larvae avoid light during the foraging stage of their development. Research published in the open access journal BMC Neuroscience shows that both 5-HT (serotonergic) and corazonergic neurons have a role in regulating this behavior. view more (2009-06-23)
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)
Common autism medication is ineffective for repetitive behaviors, study finds
Citalopram (Celexa), a medication commonly prescribed to children with autism spectrum disorders (ASD), was no more effective than a placebo at reducing repetitive behaviors. view more (2009-06-02)
Citalopram no better than placebo treatment for children with autism spectrum disorders
Citalopram, a medication commonly prescribed to children with autism spectrum disorders (ASD), was no more effective than a placebo at reducing repetitive behaviors. view more (2009-06-02)
