Is sexual addiction the real deal?

Controversy exists over what some mental health experts call “hypersexuality,” or sexual “addiction.” Namely, is it a mental disorder at all, or something else? It failed to make the cut in the recently updated Diagnostic and Statistical Manual of Mental Disorders, or DSM-5, considered the bible for diagnosing mental disorders. Yet sex addiction has been blamed for ruining relationships, lives and careers.

Now, for the first time, UCLA researchers have measured how the brain behaves in so-called hypersexual people who have problems regulating their viewing of sexual images. The study found that the brain response of these individuals to sexual images was not related in any way to the severity of their hypersexuality but was instead tied only to their level of sexual desire.

A constitutional right to health care

UCLA-led study shows that many countries have it, but not the U.S.

Uruguay has it. So does Latvia, and Senegal. In fact, more than half of the world’s countries have some degree of a guaranteed, specific right to public health and medical care for their citizens written into their national constitutions.

The United States is one of 86 countries whose constitutions do not guarantee their citizens any kind of health protection. That’s the finding of a new study from the UCLA Fielding School of Public Health that examined the level and scope of constitutional protection of specific rights to public health and medical care, as well as the broad right to health.

Among Indian immigrants, religious practice and obesity may be linked, study shows

Asian Indians are one of the fastest growing ethnic groups in the United States, and roughly half a million people of Indian ancestry live in California — more than any other state. Individuals from this group are strongly predisposed to obesity-related conditions such as diabetes and heart disease, due in large part to physical inactivity, diets low in fruit and vegetables, and insulin resistance.

A team of researchers at the IRCM, led by Dr. Javier M. Di Noia in the Immunity and Viral Infections research division, discovered a novel research model for the study of auto-immune diseases. The Montréal scientists are the first to find a way to separate two important mechanisms that improve the quality of antibodies. This study was featured in a recent issue of The Journal of Immunology. (more…)

Link between low vitamin D blood levels and heart disease varies by race

Low vitamin D blood levels are linked to greater risk of heart disease in whites and Chinese, but not in blacks and Hispanics, according to a study appearing this week in JAMA, the Journal of the American Medical Association.

Growing evidence has suggested that low blood levels of 25-hydroxyvitamin are associated with higher risk of developing coronary heart disease among whites. Few of these studies included substantial numbers of people from other races. (more…)

Good Vibrations: Mediating Mood Through Brain Ultrasound

Ultrasound vibrations applied to the brain may affect mood, UA researchers have discovered. The finding potentially could lead to new treatments for psychological and psychiatric disorders.

University of Arizona researchers have found in a recent study that ultrasound waves applied to specific areas of the brain appear able to alter patients’ moods. The discovery has led the scientists to conduct further investigations with the hope that this technique could one day be used to treat conditions such as depression and anxiety.

Dr. Stuart Hameroff, professor emeritus of the UA’s departments of anesthesiology and psychology and director of the UA’s Center for Consciousness Studies, is lead author on the first clinical study of brain ultrasound, which was published in the journal Brain Stimulation. (more…)
