Finding may eventually help tailor treatment for depression
When a treatment works for one person's depression, it does not always work for another person's. Findings from the University of Iowa may one day help doctors have a better idea of who will benefit from specific antidepressants, increasing the likelihood of successful treatment. view more (2007-11-08)
Nobelist discovers antidepressant protein in mouse brain
A protein that seems to be pivotal in lifting depression has been discovered by a Nobel Laureate researcher funded by the National Institutes of Health's National Institute of Mental Health (NIMH). view more (2006-01-06)
The Effects of Ecstasy - It Takes Two to Tango in the Cell
Amphetamine derivatives like the life style drug Ecstasy cause the release of neurotransmitters through an ingenious interplay of cellular components: an enzyme causes two transport proteins of the same type to work in opposite directions. These new findings are in contrast to previous assumptions that individual transport proteins alone were... view more... (2005-02-21)
Forsyth scientists find linkages between serotonin reuptake inhibitors and bone mass
Scientists at The Forsyth Institute have found that fluoxetine (Prozac), a drug used in the treatment of depression and obsessive-compulsive disorders, increases bone mass. view more (2006-10-13)
Advances in brain imaging for epilepsy
Positron emission tomography (PET) brain scans of a brain chemical messenger system may prove sensitive enough to help plan brain surgery for epilepsy, according to a study presented at the 130th annual meeting of the American Neurological Association in San Diego. view more (2005-09-22)
Univ. of Chicago scientists find potential cause of breathing problems in Rett Syndrome children
A multi-institutional team, led by University of Chicago researchers, has taken a crucial step toward understanding and treating Rett syndrome (RS), a rare and often-misdiagnosed neurodevelopmental disorder that affects 1 in 10,000 children, mostly females. view more (2005-12-14)
Are Anxiety Disorders All in the Mind?
Using single-photon emission computed tomography (SPECT), researchers in The Netherlands were able to detect biochemical differences in the brains of individuals with generalized social anxiety disorder (also known as social phobia), providing evidence of a long-suspected biological cause for the dysfunction. view more (2008-05-13)
Researchers iron out new role for serotonin
Vanderbilt University Medical Center investigators have found a surprising link between brain iron levels and serotonin, a neurotransmitter involved in neuropsychiatric conditions ranging from autism to major depression. view more (2009-01-28)
Antidepressant ineffective against autism spectrum disorder children's obsessive behavior
A new multi-center study, conducted at The Feinstein Institute for Medical Research in collaboration with five other centers throughout the country, tested the commonly prescribed antidepressant citalopram and found that it was no more effective than placebo in altering obsessive features of the condition - the spinning, rocking and repetitive... view more...

Mother-daughter conflict, low serotonin level may be deadly combination
A combination of negative mother-daughter relationships and low blood levels of serotonin, an important brain chemical for mood stability, may be lethal for adolescent girls, leaving them vulnerable to engage in self-harming behaviors such as cutting themselves. view more (2008-03-06)
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)
Adolescent but not adult hamsters are more aggressive on low dose of fluoxetine
New research offers tantalizing clues as to why some teenagers taking common anti-depressants may become more aggressive or kill themselves. view more (2006-10-16)
Gene influences antidepressant response
Whether depressed patients will respond to an antidepressant depends, in part, on which version of a gene they inherit. view more (2006-03-17)
Depression linked to previously unknown dopamine regulator
Researchers from Harvard Medical School have found a molecule that is unexpectedly involved in dopamine signaling, and in a manner that supports the potential of dopamine as an alternative target for treating depression. view more (2005-07-29)
Ecstasy Users Live More Dangerously
Long-term users of the 'club drug' Ecstasy can assess risks considerably less accurately than people who have never taken Ecstasy, even when the former are not on the drug. Furthermore Ecstasy, whose chemical abbreviation is MDMA, also seems to permanently impair memory to an appreciable extent. This is revealed in a recent study by the... view more... (2004-05-18)
Depression diversity: Brain studies reveal big differences among individuals
Depressed people may have far fewer of the receptors for some of the brain's "feel good" stress-response chemicals than non-depressed people, new University of Michigan Depression Center research shows. view more (2008-05-08)
Eating and weight gain not necessarily linked, study shows
A new study shows that increased eating does not necessarily lead to increased fat. The finding in the much-studied roundworm opens the possibility of identifying new targets for drugs to control weight, the researchers say. view more (2008-06-04)
Sleepy fruit flies provide clues to learning and memory
Researchers at the University of Pennsylvania School of Medicine have discovered that a brain region previously known for its role in learning and memory also serves as the location of sleep regulation in fruit flies. view more (2006-06-16)
Commonly prescribed antidepressants associated with lower bone density in older men and women
The class of antidepressant medications known as selective serotonin reuptake inhibitors may be associated with an increased rate of bone loss in older men and women. view more (2007-06-26)
Why men are more aggressive: What a mother should know
Aggression in men may be due to variations in one of two genes involved in the activity of the neurotransmitter serotonin. view more (2006-06-21)
