Calming Kids’ Runaway Emotions

Brain Research Helps Understand and Treat Childhood Anxiety

Monday, May 19, 2025

It’s perfectly normal for young children to throw tantrums or be nervous on their first day of school, and for adolescents to be anxious about what their peers think of them. However, for some children and teens, negative emotions can escalate to unhealthy levels, resulting in significant distress and impairing their quality of life. 

IRP senior investigator Daniel Pine, M.D., is on a mission to understand how that happens and figure out ways to help those kids. In honor of Mental Health Month, we talked with Dr. Pine about how his research is revolutionizing the field of pediatric psychiatry and paving the way for new, non-pharmaceutical treatments.

Gender Differences in Emotional Responses May Start in the Womb

Research Suggests Hormonal Exposures In-Utero Influence Mental Health

Tuesday, April 2, 2024

Over the past few decades, broad stereotypes about how men and women behave have given way to a more nuanced understanding of the many factors that contribute to sex differences. While culture and environment undoubtedly play a huge role, it’s becoming increasingly clear that biological influences shape male and female brains differently starting at the very beginning of life. Recent IRP research sheds additional light on this age-old question by revealing that women exposed to higher levels of certain hormones in-utero had emotional responses to the stresses of the COVID-19 pandemic that more closely matched those of men.

Overturning the Orthodoxy About the Brain’s Stress Chemical

IRP Researchers Discover Unexpected Stress-Blunting Effects of Some Neurons

Wednesday, April 27, 2022

The past few years have not been easy for anyone. With world events like the COVID-19 pandemic and the war in Ukraine causing everyone to worry, it’s no surprise that during this April’s annual Stress Awareness Month observance, so many people experienced high levels of stress and anxiety. While stress management techniques and talk therapy may help some people, nearly 10 million Americans need prescription anti-anxiety drugs to quell those feelings.

One important target for anti-anxiety medications is norepinephrine, a chemical released by certain neurons in the brain. Norepinephrine — also known as noradrenaline — has traditionally been considered to be a ‘stress chemical’ that triggers anxiety. However, drugs designed to target the neurons that produce it don’t always work as predicted. That’s why IRP senior investigator Patricia Jensen, Ph.D., and her colleagues in the Developmental Neurobiology Group at the National Institute of Environmental Health Sciences (NIEHS) are delving deep into the mouse brain to better understand these neurons and what exactly they do.

Mouse Study Links Anxiety to Neuronal Power Failure

Chronic Stress Diminishes Energy Production in the Brain

Tuesday, December 7, 2021

When power lines come down and the electricity shuts off, it’s understandably a worrying situation. As it turns out, people may become anxious not just when their homes are cut off from energy, but also when their brains find themselves short on power, according to recent IRP research done in mice.

While the misfortune of a blackout is temporary, many people experience chronic stress that bothers them continuously. In some individuals, repetitive stressors can contribute to the development of debilitating anxiety that interferes with everyday life. Intriguingly, past research has found evidence that problems with the biological batteries that power our cells, called mitochondria, might be involved in anxiety disorders, as well as some other psychiatric illnesses.

Brief Mindfulness Program Reduces Healthcare Workers’ Stress

IRP Study Examines Less Time-Intensive Method for Improving Mental Health

Tuesday, January 5, 2021

While working in healthcare can be extremely rewarding, it is also undoubtedly stressful. In particular, the COVID-19 pandemic has had severe repercussions on the mental health of medical professionals, as doctors and nurses struggle to care for unprecedented numbers of sick patients. Fortunately, new NIH research suggests that a relatively brief workplace mindfulness program can reduce stress and anxiety in healthcare workers.

Psychological Stress Damages Brain’s Blood Vessels

Mouse Study Illuminates Potential Mechanism Behind Mood and Anxiety Disorders

Millions of Americans suffered from depression and anxiety even before COVID-19 began upending their lives. To make matters worse, the stresses of living through a pandemic might not only worsen mental health but could also wreak havoc on the brain itself. New IRP research has found that psychological stress damages blood vessels in the brains of mice and dramatically alters the behavior of genes in certain blood vessel cells.

IRP Interns Shine at Summer Poster Day

NIH summer intern Ishu Sivakumar at Summer Poster Day

Upon entering the sunny foyer of the NIH’s Natcher Conference Center last Thursday, I was immediately struck by a burst of loud, excited chatter. As it always is on NIH’s annual Summer Poster Day, the building was filled with hundreds of high school and college students and the scientists, families, and friends who had turned out to see what these young men and women had spent the summer doing.

Which Neurons Are Responsible for Anxiety-Related Behaviors?

Most people experience anxiety at some point in their lives, whether it’s pre-speech jitters or sweaty palms when their plane takes off. While mild feelings of nervousness are completely normal and can even be beneficial, anxiety can also have negative repercussions if it causes somebody to completely avoid situations like social encounters or taking a flight to visit distant family.
