Scientists from UCLA, UC San Francisco, Costa Rica and Colombia take steps to identify genetic component to mental illness
Scientists know there is a strong genetic component to bipolar disorder, but they have had an extremely difficult time identifying the genes that cause it. So, in an effort to better understand the illness’s genetic causes, researchers at UCLA tried a new approach. (more…)
A new study of patients with bipolar disorder finds that 36 percent of those who were admitted to a Rhode Island psychiatric hospital in 2010 were receiving “complex polypharmacy” — four or more psychotropic medications — from their community providers. The polypharmacy rate was significantly higher for women. Including prescriptions for other conditions the patients may have had, the average patient was on six medications. (more…)
The internal circadian clock of a Drosophila (fruit fly) can be synchronised using vibrations, according to research published today in the journal Science. The study suggests that an animal’s own movements can influence its clock.
The circadian clock, which underlies the daily rhythms characterising most of our bodily functions, including the sleep cycle, is mainly set by diurnal changes in light and temperature. (more…)
UCLA researchers test proposed criteria for diagnosing ‘hypersexual disorder’
The idea that an individual might suffer from a sexual addiction is great fodder for radio talk shows, comedians and late night TV. But a sex addiction is no laughing matter. Relationships are destroyed, jobs are lost, lives ruined.
Yet psychiatrists have been reluctant to accept the idea of out-of-control sexual behavior as a mental health disorder because of the lack of scientific evidence.
Now a UCLA-led team of experts has tested a proposed set of criteria to define “hypersexual disorder,” also known as sexual addiction, as a new mental health condition. (more…)
*UCLA-launched partnership identifies genes that boost or lessen risk of brain atrophy, mental illness, Alzheimer’s disease*
In the world’s largest brain study to date, a team of more than 200 scientists from 100 institutions worldwide collaborated to map the human genes that boost or sabotage the brain’s resistance to a variety of mental illnesses and Alzheimer’s disease.
Published April 15 in the advance online edition of the journal Nature Genetics, the study also uncovers new genes that may explain individual differences in brain size and intelligence. (more…)
As a researcher, Yale psychologist June Gruber has confirmed the many positive physical, social and psychological benefits of human happiness.
While working as a clinical scientist at the University of California-Berkeley, however, she witnessed extreme and damaging bouts of positive emotion during periods of mania in bipolar disorder. (more…)
