Use of torture around the world has not diminished but the techniques used have grown more complex and sophisticated, according to new research from Queen Mary, University of London.

The study suggests that these emerging forms of torture, which include various types of rape, bestiality and witnessing violent acts, are experienced by people seeking asylum in the UK.

In many cases the techniques cause no visible effect but are responsible for a variety of serious mental health problems. The researchers say that their findings are vital for understanding what many asylum seekers have endured and for ensuring the correct medical treatments are available.

Results of a new study from the University of North Carolina at Chapel Hill may help pave the way to a treatment for a neurogenetic disorder often misdiagnosed as cerebral palsy or autism.

Known as Angelman syndrome, or AS, its most characteristic feature is the absence or near absence of speech throughout the person's life. Occurring in one in 15,000 live births, other AS characteristics include intellectual and developmental delay, severe intellectual disability, seizures, sleep disturbance, motor and balance disorders. Individuals with the syndrome typically have a happy, excitable demeanor with frequent smiling, laughter, and hand flapping.

A new working definition of recovery from mental disorders and substance use disorders is being announced by the Substance Abuse and Mental Health Services Administration (SAMHSA). The definition is the product of a year-long effort by SAMHSA and a wide range of partners in the behavioral health care community and other fields to develop a working definition of recovery that captures the essential, common experiences of those recovering from mental disorders and substance use disorders, along with major guiding principles that support the recovery definition. SAMHSA led this effort as part of its Recovery Support Strategic Initiative.

The new working definition of Recovery from Mental Disorders and Substance Use Disorders is as follows:

Thoughts about killing oneself and engaging in suicidal behavior may begin much younger than previously thought. While about one of nine youths attempt suicide by the time they graduate from high school, new findings reveal that a significant proportion make their first suicide attempt in elementary or middle school.

In a study published in the November issue of the Journal of Adolescent Health, nearly 40 percent of young adults who said they had tried suicide said that they made their first attempt before entering high school.

They say time heals all wounds, and new research from the University of California, Berkeley, indicates that time spent in dream sleep can help.

UC Berkeley researchers have found that during the dream phase of sleep, also known as REM sleep, our stress chemistry shuts down and the brain processes emotional experiences and takes the painful edge off difficult memories.

The findings offer a compelling explanation for why people with post-traumatic stress disorder (PTSD), such as war veterans, have a hard time recovering from painful experiences and suffer reoccurring nightmares.They also offer clues into why we dream.

Aging and health issues facing lesbian, gay, bisexual and transgender baby boomers have been largely ignored by services, policies and research. These seniors face higher rates of disability, physical and mental distress and a lack of access to services, according to the first study on aging and health in these communities.

The study, led by Karen Fredriksen-Goldsen and colleagues at the University of Washington's School of Social Work, indicates that prevention and intervention strategies must be developed to address the unique needs of these seniors, whose numbers are expected to double to more than 4 million by 2030.

New research identifies the brain chemicals and circuits involved in mental illnesses like schizophrenia, depression, and anxiety, giving potential new directions to their treatment. In addition, research with children shows that early-life depression and anxiety changes the structure of the developing brain. The findings were presented at Neuroscience 2011, the Society for Neuroscience's annual meeting and the world's largest source of emerging news about brain science and health.

One in 17 Americans suffer from a serious mental illness, such as schizophrenia, major depression, or bipolar disorder, making it one of the leading causes of disability. Yet science is only beginning to understand the underlying physical causes of these diseases.

Prior to the 1984 passage of a uniform drinking-age limit of 21 years in the U.S., many states permitted the legal purchase of alcohol at age 18. These lower drinking ages have been associated with several adverse outcomes such as higher rates of suicide and homicide among youth. A new study of individuals who were legally permitted to drink before the age of 21 has found they remain at elevated risk for suicide and homicide as adults, particularly women born after 1960.

Results will be published in the February 2012 issue of Alcoholism: Clinical & Experimental Research and are currently available at Early View.

In this week's PLoS Medicine, Shekhar Saxena of the WHO in Geneva, Switzerland and colleagues summarize the recent WHO Mental Health Gap Action Programme (mhGAP) intervention guide that provides evidence-based management recommendations for mental, neurological, and substance use (MNS) disorders.

This guide is aimed at reducing the treatment gap for MNS disorders, which is more than 75% in many low- and middle-income countries (LMICs). Further details and background material to the guide can be accessed on the WHO website: http://bit.ly/vKPSRF

Seclusion should always be the last resort when it comes to dealing with aggressive episodes involving young offenders with psychiatric disorders, according to staff who took part in a four-country study published in the November issue of the Journal of Psychiatric and Mental Health Nursing.

Researchers led by the Universities of Turku and Tampere, Finland, report that the multi-disciplinary teams they spoke to said that verbal intervention was their first choice. Putting adolescents in a bare, locked room was viewed as the least favoured option in the three countries where seclusion remains legal.
