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…)
Major depression or chronic stress can cause the loss of brain volume, a condition that contributes to both emotional and cognitive impairment. Now a team of researchers led by Yale scientists has discovered one reason why this occurs — a single genetic switch that triggers loss of brain connections in humans and depression in animal models.
The findings, reported in the Aug. 12 issue of the journal Nature Medicine, show that the genetic switch known as a transcription factor represses the expression of several genes that are necessary for the formation of synaptic connections between brain cells, which in turn could contribute to loss of brain mass in the prefrontal cortex.

EAST LANSING, Mich. — A parasite thought to be harmless and found in many people may actually be causing subtle changes in the brain, leading to suicide attempts.
New research appearing in the August issue of The Journal of Clinical Psychiatry adds to the growing work linking an infection caused by the Toxoplasma gondii parasite to suicide attempts. Michigan State University’s Lena Brundin was one of the lead researchers on the team.
About 10-20 percent of people in the United States have Toxoplasma gondii, or T. gondii, in their bodies, but in most it was thought to lie dormant, said Brundin, an associate professor of experimental psychiatry in MSU’s College of Human Medicine. In fact, it appears the parasite can cause inflammation over time, which produces harmful metabolites that can damage brain cells. (more…)
UCLA study also finds that mindfulness technique benefits immune system
Many elderly people spend their last years alone. Spouses pass and children scatter. But being lonely is much more than a silent house and a lack of companionship. Over time, loneliness not only takes a toll on the psyche but can have a serious physical impact as well.
Feeling lonely has been linked to an increased risk of heart disease, Alzheimer’s disease, depression and even premature death. Developing effective treatments to reduce loneliness in older adults is essential, but previous treatment efforts have had limited success. (more…)
COLUMBUS, Ohio – Chronic exposure to dim light at night can lead to depressive symptoms in rodents – but these negative effects can be reversed simply by returning to a standard light-dark cycle, a new study suggests.
While hamsters exposed to light at night for four weeks showed evidence of depressive symptoms, those symptoms essentially disappeared after about two weeks if they returned to normal lighting conditions.
Even changes in the brain that occurred after hamsters lived with chronic light at night reversed themselves after returning to a more normal light cycle. (more…)
Understanding this phenomenon could improve psychological support systems for sexual minorities and help young people avoid alcohol problems.
COLUMBIA, Mo. — Many young adults explore and define their sexual identity in college, but that process can be stressful and lead to risky behaviors. In a new study, students whose sexual self-definition didn’t fall into exclusively heterosexual or homosexual categories tended to misuse alcohol more frequently than people who had a firmly defined sexual orientation for a particular gender, according to University of Missouri researchers. These findings could be used to improve support programs for sexual minorities.
“Bisexuals and students whose sexual orientation was in flux reported the heaviest drinking and most negative consequences from alcohol use, such as uncontrolled drinking and withdrawal symptoms,” said Amelia Talley, MU assistant professor of psychological sciences in the College of Arts and Science. “Those groups reported drinking to relieve anxiety and depression at higher rates than strictly heterosexual or homosexual individuals. One possible explanation is that people who aren’t either completely heterosexual or homosexual may feel stigmatized by both groups.” (more…)
The summer is here, which means child day care centers and summer camps will soon be flooded with vast amounts of children. While typically people are more concerned with who is handling their child and thus mandate background checks for all employees, sometimes it’s the parents who are at fault and cause harm to their children. That’s why it is so important to remind educators, advisors and camp counselors (who are all too often children themselves—most are college aged) how to closely monitor the signs and detect child abuse and neglect.
While national statistics say child abuse is reported every ten seconds, unfortunately most of those cases are not made by child daycare workers—a place where child interaction occurs the most. In fact, studies show that underreporting is a common thread among child day care centers and summer camps, mostly because employees don’t want to get involved, fear they may be wrong, or don’t know the common signs of child abuse. With that said, if you are suspicious a child in your care may be suffering from child abuse because he or she is experiencing one or all of the symptoms listed below, it’s best to talk with an authoritative figure and report the case.

When 25 percent of the payments to community health clinics were based on quality of care, patients received better care and had better depression outcomes. The results of this initiative are published in the American Journal of Public Health.
University of Washington researchers examined records from almost 8,000 patients treated for depression in 29 community health clinics in the Washington State Mental Health Integration Program before and after the implementation of a pay-for-performance incentive. After the incentive was started, patients were seen more quickly and were more likely to receive consultation from a psychiatrist. They were also more likely to show improvements in their depression.
