- Teen Brain Less Discerning of Threat vs. Safety, More Vulnerable to Stress
- Science Update
Teen brains rely on early-maturing brain structures that process fear differently than adult brains, according to an NIMH-funded study. As a result, teens may have more difficulty than adults in differentiating between danger and safety, leading to more pervasive stress and anxiety. The study was published online ahead of print on February 23, 2011, in the Proceedings of the National Academy of Sciences.
- Light Switches Brain Pathway On-and-Off to Dissect How Anxiety Works
- Science Update
Scientists, for the first time, have switched anxiety on-and-off in active animals by shining light at a brain pathway. Instinctively reclusive mice suddenly began exploring normally forbidding open spaces when a blue laser activated the pathway – and retreated into a protected area when it dimmed. By contrast, anxiety-like behaviors increased when an amber laser inhibited the same pathway.
- Nurturing Newborn Neurons Sharpens Minds in Mice
- Press Release
Adult mice engineered to have more newborn neurons in their brain memory hub excelled at accurately discriminating between similar experiences – an ability that declines with normal aging and in some anxiety disorders. Boosting such neurogenesis in the adult hippocampus also produced antidepressant-like effects when combined with exercise, in the study funded by the National Institutes of Health.
- Enzyme Enhances, Erases Long-term Memories in Rats
- Press Release
Even long after it is formed, a memory in rats can be enhanced or erased by increasing or decreasing the activity of a brain enzyme, say researchers supported, in part, by the National Institutes of Health.
- Brain Activity Patterns in Anxiety-Prone People Suggest Deficits in Handling Fear
- Science Update
Anxiety as a personality trait appears to be linked to the functioning of two key brain regions involved in fear and its suppression, according to an NIMH-funded study. Differences in how these two regions function and interact may help explain the wide range of symptoms seen in people who have anxiety disorders. The study was published February 10, 2011 in the journal, Neuron.
- Stress Hormone Receptors Less Adaptive in Female Brain
- Science Update
A study in rats has revealed striking gender difference in the brain’s stress response that could shed light on women’s proneness to mood and anxiety disorders. Female rat brain cells were more sensitive to a key stress hormone than males’, which could adapt to the hormone in a way female cells couldn’t.

- Science Update
A coordinated, multi-component treatment approach was more effective in treating anxiety disorders than usual care found in primary care settings, according to an NIMH-funded study published May 19, 2010, in a special issue of the Journal of the American Medical Association devoted to mental health.
- Gene’s Impact on Forgetting a Fear-Based Memory Same in Humans and Mice
- Science Update
Both humans and mice carrying a variant of a gene that plays a role in memory were slow to learn to forget a fear-based memory. The parallels in gene effects observed in mice and humans in this work means that investigation using the mouse model can provide insights into effects in humans; results may inform treatment approaches to anxiety disorders such as post-traumatic stress disorder.
- Non-Invasive Technique Blocks a Conditioned Fear in Humans
- Press Release
Scientists have for the first time selectively blocked a conditioned fear memory in humans with a behavioral manipulation. Participants remained free of the fear memory for at least a year. The research builds on emerging evidence from animal studies that reactivating an emotional memory opens a 6-hour window of opportunity in which a training procedure can alter it.
- Brain Emotion Circuit Sparks as Teen Girls Size Up Peers
- Press Release
What is going on in teenagers’ brains as their drive for peer approval begins to eclipse their family affiliations? Brain scans of teens sizing each other up reveal an emotion circuit activating more in girls as they grow older, but not in boys. The study by Daniel Pine, M.D., of the National Institute of Mental Health (NIMH), part of National Institutes of Health, and colleagues, shows how emotion circuitry diverges in the male and female brain during a developmental stage in which girls are at increased risk for developing mood and anxiety disorders.

- Human Brain Appears “Hard-Wired” for Hierarchy
- Press Release
Human imaging studies have for the first time identified brain circuitry associated with social status, according to researchers at the National Institute of Mental Health (NIMH) of the National Institutes of Health. They found that different brain areas are activated when a person moves up or down in a pecking order – or simply views perceived social superiors or inferiors. Circuitry activated by important events responded to a potential change in hierarchical status as much as it did to winning money.
- Journal Highlights Effectiveness of Research Based Psychotherapies for Youth
- Science Update
Reviews of the current research on psychosocial and behavioral therapies, or psychotherapies, for children and adolescents found a number of "well established" and "probably efficacious" treatments for many mental disorders. For example, six were "probably efficacious" for anxiety disorders, and two were "well established" for attention deficit hyperactivity disorder (ADHD), according to scientists funded by NIMH and the National Institute on Drug Abuse, divisions of the National Institutes of Health.
- Co-occurring Anxiety Complicates Treatment Response for Those with Major Depression
- Science Update
People with major depression accompanied by high levels of anxiety are significantly less likely to benefit from antidepressant medication than those without anxiety, according to a study based on data from the NIMH-funded Sequenced Treatment Alternatives to Relieve Depression (STAR*D) study. The study was published online ahead of print in January 2008, in the American Journal of Psychiatry.
