Psychiatry has a new theory of genes and behavior: Genetic tug-of-war determines brain development
Darkfrog submitted, created time 1 week 3 days (www.nytimes.com)
In what the New York Times calls a "creative" interpretation of recent findings about the nature of DNA, two scientists, biologist Bernard Crespi of Fraser University and sociologist Christopher Badcock of the London school of economics, have come up with a new idea of how mental disorders develop and how genes fit into the whole thing:
"Their idea is, in broad outline, straightforward. Dr. Crespi and Dr. Badcock propose that an evolutionary tug of war between genes from the father’s sperm and the mother’s egg can, in effect, tip brain development in one of two ways

Since the time of ancient Egypt, societies have struggled to understand mental illness and to care for those affected by it. But, over the millennia, the idea that mental illness might have a biological cause arose only intermittently, and treatments ranged from the benign (exercise, humour and music) to the barbaric (exorcism, imprisonment and lobotomy). By the mid-twentieth century, however, several breakthroughs had been made
UPDATE 1-FDA Backs Astra's Seroquel XR for bipolar disorder
jerry submitted, created time 1 month 1 week (www.reuters.com)
U.S. regulators have approved AstraZeneca's (AZN.L: Quote, Profile, Research, Stock Buzz) drug Seroquel XR as a treatment for bipolar disorder, extending the medicine's use beyond schizophrenia, the Anglo-Swedish company said ...
Gene mutations reveal schizophrenia's complexity
sea-maid submitted, created time 3 months 1 day (www.newscientist.com)
The three largest genetic schizophrenia studies to date have uncovered several ways in which changes to the genome may increase the risk of developing the condition.
The studies bring to light several common variations that increase the risk slightly, and rarer ones that raise it significantly, researchers say.
Early pregnancy trauma boosts schizophrenia risk

Excessive stress is never a good thing, but new research suggests that children of women who suffered severe psychological stress during early pregnancy are more likely to develop schizophrenia. ...
Madness: Price of a Big Brain?
sea-maid submitted, created time 3 months 1 week (sciencenow.sciencemag.org)
A new study suggests that the debilitating disease schizophrenia may be a byproduct of the genetic changes that fueled the evolution of the expansive human brain. The idea, still preliminary, is that the massive energy demands of the brain may make it vulnerable to mutations in metabolism-related genes.
Missing DNA Boosts Risk of Schizophrenia

Two large studies of schizophrenia patients have yielded the most convincing evidence yet that the disease can be caused by mistakes in genes. The researchers linked a much higher risk for schizophrenia to three chromosomal regions that are missing chunks of DNA. Although only a tiny fraction of patients carried these particular glitches, similar errors may help explain other cases of the disease.
Gene surveys identify schizophrenia triggers
sea-maid submitted, created time 3 months 3 weeks (www.nature.com)
Rare genetic changes associated with a heightened risk of schizophrenia have been revealed by two independent studies.
The surveys have identified sections of the human genome that, when deleted, can elevate the risk of developing schizophrenia by up to fifteen times compared with the general population.
Sex and Drugs and Singing Mice
Vincent submitted, created time 7 months 2 weeks (sciencenow.sciencemag.org)
Mice can whistle and chirp like birds--and researchers now say their songs seem to be happy ones. New experiments associate the rodents' ultrasonic chatter with the brain's dopamine-based reward system, and investigators hope that studying the songs may eventually point toward genes behind human emotional disorders such as schizophrenia and autism.
Genetic Link to Schizophrenia Discovered
Sue Wu submitted, created time 7 months 3 weeks (sciencenow.sciencemag.org)
Researchers have found that people with schizophrenia are far more likely than other people to have a certain type of error in their genes. Scientists believe the finding will help them develop new treatments for schizophrenia and identify young people at high risk of developing the disorder.
It's No Delusion: Evolution May Favor Schizophrenia Genes
wugongliang submitted, created time 1 year 6 days (www.sciam.com)
Schizophrenia, the psychotic disorder marked by hallucinations, delusions and cognitive disorganization, affects roughly 1 percent of the U.S. population.* Many of those afflicted, however, also have reduced reproductive fitness, which means they are less likely to pass a genetic profile associated with the condition onto their offspring.
How schizophrenia develops: Major clues discovered
richard submitted, created time 1 year 1 month (www.eurekalert.org)
We know that something happens during brain development that contributes to schizophrenia. A glitch in the process that turns genes on and off in the brain -- a specific "epigenetic" flaw -- appears to be part of the problem.
Impaired glutathione synthesis in schizophrenia: Convergent genetic and functional evidence
jimmy submitted, created time 1 year 1 month (www.pnas.org)
Schizophrenia is a complex multifactorial brain disorder with a genetic component. Convergent evidence has implicated oxidative stress and glutathione (GSH) deficits in the pathogenesis of this disease. The aim of the present study was to test whether schizophrenia is associated with a deficit of GSH synthesis.
Evidence found for novel brain cell communication
bianjie submitted, created time 1 year 4 months (www.eurekalert.org)
An article published today, July 16, 2007, in Proceedings of the National Academy of Sciences provides strong evidence for a novel type of communication between nerve cells in the brain. The findings may have relevance for the prevention and treatment of epilepsy, and possibly in the exploration of other aspects of brain functions, from creative thought processes to mental illnesses such as schizophrenia. The discovery suggests the first new model of brain function since the 1940s.

"These results indicate that patients with schizophrenia exhibit white matter abnormalities at the time of their first presentation of psychotic symptoms to mental health services and that these abnormalities degenerate further over the initial years of illness. Given the role that white matter plays in neural communication, the authors suggest that these white matter abnormalities may be a cause of the dysfunctional neural connectivity that has been proposed to underlie the symptoms of schizophrenia."
