Findings may help identify teens who are at risk for dangerous behaviors in the future

Findings may help identify teens who are at risk for dangerous behaviors in the future

According to the CDC, unintentional injuries are the leading cause of death for adolescents. Compared to the two leading causes of death for all Americans, heart disease and cancer, a pattern of questionable decision-making in dire situations comes to light in teen mortality. [More]
Even with no explicit memory of childhood trauma, PTSD can develop in adulthood

Even with no explicit memory of childhood trauma, PTSD can develop in adulthood

There are many forms of memory and only some of these may be critical for the development of posttraumatic stress disorder (PTSD), reports a new study by researchers at the University at Albany and the University of California Los Angeles. [More]
Study: Effects of testosterone on brain's response to threat cues in healthy men

Study: Effects of testosterone on brain's response to threat cues in healthy men

A new study in Biological Psychiatry reports on a neural circuit for male aggression. Testosterone, a steroid hormone, is well known to contribute to aggressive behavior in males, but the neural circuits through which testosterone exerts these effects have not been clear. [More]
Molecule Notch involved in fear memory formation

Molecule Notch involved in fear memory formation

Nature is thrifty. The same signals that embryonic cells use to decide whether to become nerves, skin or bone come into play again when adult animals are learning whether to become afraid. [More]
Subtle changes in gene can predict how brain reacts to stress

Subtle changes in gene can predict how brain reacts to stress

Scientists studying depression in teens have discovered that subtle changes in a gene can predict how the brain reacts to stress, which can cause such health issues as depression, post-traumatic stress disorder and obesity. [More]
Epigenetic control of serotonin transporter predicts human brain function

Epigenetic control of serotonin transporter predicts human brain function

The tiny addition of a chemical mark atop a gene that is well known for its involvement in clinical depression and posttraumatic stress disorder can affect the way a person's brain responds to threats, according to a new study by Duke University researchers. [More]
Researchers find differences in brain wiring between children with SPD and those with autism

Researchers find differences in brain wiring between children with SPD and those with autism

Researchers at UC San Francisco have found that children with sensory processing disorders have decreased structural brain connections in specific sensory regions different than those in autism, further establishing SPD as a clinically important neurodevelopmental disorder. [More]
New electrical pattern in brains predicts how well individual animals fare in stressful situations

New electrical pattern in brains predicts how well individual animals fare in stressful situations

Some people can handle stressful situations better than others, and it's not all in their genes: Even identical twins show differences in how they respond. [More]
Drug paraphernalia triggers reward areas of brain differently in marijuana users

Drug paraphernalia triggers reward areas of brain differently in marijuana users

New research from The University of Texas at Dallas demonstrates that drug paraphernalia triggers the reward areas of the brain differently in dependent and non-dependent marijuana users. [More]

Brain activity in people with sex addiction similar to that of drug addicts

Pornography triggers brain activity in people with compulsive sexual behaviour - known commonly as sex addiction - similar to that triggered by drugs in the brains of drug addicts, according to a University of Cambridge study published in the journal PLOS ONE. [More]
Research finding may accelerate development of treatments for PTSD

Research finding may accelerate development of treatments for PTSD

Scientists at Yerkes National Primate Research Center, Emory University have identified a drug that appears to make memories of fearsome events less durable in mice. [More]
Early life stress can have lasting negative impacts on the brain

Early life stress can have lasting negative impacts on the brain

For children, stress can go a long way. A little bit provides a platform for learning, adapting and coping. But a lot of it - chronic, toxic stress like poverty, neglect and physical abuse - can have lasting negative impacts. [More]
Tinnitus patients process emotions differently in brain from those with normal hearing

Tinnitus patients process emotions differently in brain from those with normal hearing

Patients with persistent ringing in the ears - a condition known as tinnitus - process emotions differently in the brain from those with normal hearing, researchers report in the journal Brain Research. [More]
Brain activation differences hint at developing course of bipolar disorder

Brain activation differences hint at developing course of bipolar disorder

Results of an activation likelihood estimation meta-analysis highlight the differences and similarities in brain activation between youths and adults with bipolar disorder. [More]
Children may benefit from targeted treatments specific to pediatric brain activity

Children may benefit from targeted treatments specific to pediatric brain activity

A new study from Bradley Hospital has found that bipolar children have greater activation in the right amygdala - a brain region very important for emotional reaction - than bipolar adults when viewing emotional faces. [More]

Study analyses link between childhood maltreatment and volume of cerebral grey matter

An international study has analysed the association between childhood maltreatment and the volume of cerebral grey matter, responsible for processing information. [More]
Amygdala alterations during childhood may influence development of anxiety problems

Amygdala alterations during childhood may influence development of anxiety problems

The amygdala is a key "fear center" in the brain. Alterations in the development of the amygdala during childhood may have an important influence on the development of anxiety problems, reports a new study in the current issue of Biological Psychiatry. [More]
Global scientists to discuss latest findings on diagnosis, causes and treatments of ASD

Global scientists to discuss latest findings on diagnosis, causes and treatments of ASD

The International Society for Autism Research (INSAR), a scientific and professional organization devoted to advancing knowledge about autism spectrum disorders, convened more than 1700 researchers, delegates, autism specialists and students from 40 countries for the 13th Annual International Meeting for Autism Research (IMFAR), the world's largest scientific gathering on autism research, from May 15 through May 17 at the Atlanta Marriott Marquis in Atlanta, GA.

Psilocybin in magic mushroom inhibits negative emotions in brain, shows study

Psilocybin in magic mushroom inhibits negative emotions in brain, shows study

Emotions like fear, anger, sadness, and joy enable people to adjust to their environment and react flexibly to stress and strain and are vital for cognitive processes, physiological reactions, and social behaviour. [More]
Neuroinflammation levels higher in patients with chronic fatigue syndrome

Neuroinflammation levels higher in patients with chronic fatigue syndrome

Researchers at the RIKEN Center for Life Science Technologies, in collaboration with Osaka City University and Kansai University of Welfare Sciences, have used functional PET imaging to show that levels of neuroinflammation, or inflammation of the nervous system, are higher in patients with chronic fatigue syndrome than in healthy people.
