Mental health intervention can help prevent suicides among youth

Roughly 1 million people die by suicide each year. In the U.S., where nearly 36,000 people take their own lives annually, more than 4,600 victims are between the ages of 10 and 24, making suicide the third leading cause of death in this age group.

Scientists discover neurons responsible for light-induced arousal response

Bright light arouses us. Bright light makes it easier to stay awake. Very bright light not only arouses us but is known to have antidepressant effects. Conversely, dark rooms can make us sleepy. It's the reason some people use masks to make sure light doesn't wake them while they sleep.

Link between poverty, fast food and obesity

A new national study of eating out and income shows that fast-food dining becomes more common as earnings increase from low to middle incomes, weakening the popular notion that fast food should be blamed for higher rates of obesity among the poor.

Novel indirect screener can identify women at risk for illicit drug use

A team of researchers at Wayne State University's Parent Health Lab in the School of Medicine have developed a novel indirect screener that identifies women at risk for drug use by evaluating correlates of illicit drug use rather than drug use itself. In phase I testing, this new screener proved to be more sensitive than any alternative approach at detecting recent drug use.

Affective symptoms can help diagnose early psychotic disorders

Functional psychosis can be diagnosed from the first indications of the patient, thanks to affective symptomatology. Depressive moods, hyperactivity and lack of concentration are affective symptoms that can present themselves during the first psychotic episodes, and the presence or absence of any of them may contribute to differentiating, at an early stage, between the different variations of the mental disease.

Study highlights profound impact of maternal separation on infants

A woman goes into labor, and gives birth. The newborn is swaddled and placed to sleep in a nearby bassinet, or taken to the hospital nursery so that the mother can rest. Despite this common practice, new research published in Biological Psychiatry provides new evidence that separating infants from their mothers is stressful to the baby.

Articles explore clinical dilemma about children's behavioral problems

Clinicians often face the challenge of trying to make sense of conflicting reports from parents, teachers, and children about a child's behavioral problems. However, a better understanding of the source and nature of these disagreements may provide important information that could improve treatment and outcomes. A group of articles in the current issue of Journal of Child and Adolescent Psychopharmacology, a peer-reviewed journal published by Mary Ann Liebert, Inc., explores this challenging clinical dilemma.

Hippocampus supports both recollection and familiarity memories

Human memory has historically defied precise scientific description, its biological functions broadly but imperfectly defined in psychological terms. In a pair of papers published in the November 2 issue of The Journal of Neuroscience, researchers at the University of California, San Diego report a new methodology that more deeply parses how and where certain types of memories are processed in the brain, and challenges earlier assumptions about the role of the hippocampus.

New e-tool to catch youth depression before it takes hold

Australian researchers will for the first time harness e-technology to develop a customised internet program to identify and arm healthy young people most at risk of depression before the illness takes hold.

Happiness good for health: Study

A new study suggests that happiness is good for health. Epidemiologists at University College, London, reported their results Monday in the journal Proceedings of the National Academies of Science.

Study: People with schizophrenia have weakened sense of body ownership

A study using a procedure called the rubber hand illusion has found striking new evidence that people experiencing schizophrenia have a weakened sense of body ownership and has produced the first case of a spontaneous, out-of-body experience in the laboratory.

Improving mother's sleep habits through early intervention could reduce risk of preterm births

Poor sleep quality in both early and late pregnancy has been linked to an increased risk of delivering preterm.

Targeted brain stimulation increases cigarette cravings

Targeted brain stimulation increases cigarette cravings, a new study in Biological Psychiatry has found, which may ultimately lead to new treatments that reverse these effects. Cues associated with cigarette smoking, such as watching someone else smoke, elicit craving and may provoke relapse when smokers are attempting to quit.

Deficits in endocannabinoid function may contribute to eating disorders

A new report in Biological Psychiatry suggests that deficits in endocannabinoid function may contribute to anorexia nervosa and bulimia.

'Deep sequencing' technology identifies new target area for depression

Scientists at the Texas Biomedical Research Institute and Yale University have identified a new target area in the human genome that appears to harbor genes with a major role in the onset of depression.

Mayo Clinic issues toolkit to identify signs of youth mental health disorders

Mayo Clinic researchers -- in partnership with numerous national mental health advocacy organizations -- are issuing new simple-to-understand tools to help identify youth who may have mental health disorders.

First rapid measurements of dopamine release in human brain

A research team led by investigators at the Virginia Tech Carilion Research Institute has demonstrated the first rapid measurements of dopamine release in a human brain and provided preliminary evidence that the neurotransmitter can be tracked in its movement between brain cells while a subject expresses decision-making behavior.

AD risk genes impact Aβ toxicity in neurons

In a development that sheds new light on the pathology of Alzheimer's disease (AD), a team of Whitehead Institute scientists has identified connections between genetic risk factors for the disease and the effects of a peptide toxic to nerve cells in the brains of AD patients.

A glimpse into non-waking consciousness of lucid dreamers

When people dream that they are performing a particular action, a portion of the brain involved in the planning and execution of movement lights up with activity. The finding, made by scanning the brains of lucid dreamers while they slept, offers a glimpse into the non-waking consciousness and is a first step toward true "dream reading,".
