Baylor Innovations, the quarterly magazine of Baylor Health Care System, featured the groundbreaking panic attack research of SMU psychologists Dr. Alicia E. Meuret, Dr. David Rosenfield and Dr. Thomas Ritz.

The Spring 2012 article by health and science writer Mark Cantrell, titled “Don’t Panic: New Research Shows That Panic Attacks Are Not As Spontaneous As Once Thought” details the startling findings of Meuret’s newest published study showing significant physiological instability in advance of so-called out-of-the-blue panic attacks.

YOUR HANDS ARE SHAKING. YOUR KNEES FEEL WEAK. You’re sweating, your heart is pounding like a jackhammer and you feel you can’t catch your breath. You’re having a panic attack, and it seems to have struck without warning.

But did it? A new study conducted at Southern Methodist University in Dallas suggests that panic attacks are actually telegraphed ahead of time by certain physiological changes.

The latest edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) defines a panic attack as a discrete period of intense fear and discomfort in which symptoms such as a racing heart, shortness of breath or dizziness develop suddenly and reach a peak in about 10 minutes.

Those experiencing an attack may believe they’re having a heart attack or stroke. But one of the most distressing things about panic attacks is that they often seem to have no actual cause.

Out of Nowhere?
“Unexpected attacks – as compared to those triggered by certain situations such as flying, being in a closed space or speaking in public – are thought to occur spontaneously, in absence of internal signals or situational triggers,” explains Alicia Meuret, Ph.D., an associate professor at Southern Methodist University and chief investigator of the study.

“The literature on how the body reacts when patients who are prone to them have an unexpected attack is very limited, due to the unexpectedness of the phenomenon. To date we do not know what triggers these attacks, but it is likely that the causes are multifactorial.”

For the study, Dr. Meuret enlisted 43 people with a history of panic attacks to wear portable monitors that captured changes in respiration, heart rate and other bodily functions.

The device was worn in a waist pack, with sensors attached at various points. Elastic bands around the chest and abdomen measured breathing rate, depth and variability.

Electrodes kept track of patients’ cardiac and sweat gland activity, while accelerometers measured body movement. Participants were instructed to press a “panic button” at the moment they felt the onset of an attack, and to write down the symptoms they were feeling at the time.

SMU News: 2012 Research Day at Southern Methodist University

Post author By Margaret Allen
Post date February 14, 2012

SMU News covered the annual 2012 Research Day on Feb. 10 where SMU graduate and undergraduate students presented results of their research studies.

Sponsored by SMU’s Office of Research and Graduate Studies, the event sought to foster communication between students in different programs, give students the opportunity to present their work in formats they will use as professionals, and to share with the SMU community and others the outstanding research being done at the University.

The students presented their studies on posters, and were available to discuss their findings and the significance of the research.

Among the projects at the event were:

Psychology student Vanessa Rae Stevens (under Professor Alicia Meuret) is studying whether people with tattoos and body piercings are also prone to intentional self injury by cutting, scratching, burning, etc.

Psychology student Grant Holland (under Professor George Holden) is studying recordings of interactions between mothers and their children with an eye toward better understanding the effects of tone-of-voice on behavior at bedtime.

Statistics student Holly Stovall (under Professor Lynne Stokes) is examining how to more precisely measure success in teaching programs for No Child Left Behind.

Earth sciences student Mary Milleson (under Professor Neil Tabor) is using core samples taken from Dallas’s White Rock Lake to gain a better understanding of how the growing urbanization of the area over the last 100 years is affecting the lake.

Computer science student Ruili Geng (under Professors Jeff Tian and Liguo Huang) is researching how to make the performance of the web and cloud computing more dependable.

Physics students Bedile Karabuga and Mayisha Zeb Nakib (under Professor Jodi Cooley-Sekula) are examining a specific technique for identifying dark matter.

Nicholas Garlow with the U.S. Department of Health and Human Services created a podcast about the groundbreaking panic attack research of SMU psychologists Dr. Alicia Meuret, Dr. David Rosenfield and Dr. Thomas Ritz.

The Sept. 22 podcast “Predicting Panic Attacks” details the startling findings of Meuret’s newest published study showing significant physiological instability in advance of so-called out-of-the-blue panic attacks.

Your body may give you hints that you’re going to have a panic attack, a short period of intense fear and discomfort. Forty-three panic attack sufferers carried portable recorders that measured respiration, heart rate and other bodily functions, over 2,000 hours.

Alice Meuret is at Southern Methodist University.

“Most of the physiological changes took place long before the patients reported that what they felt was a panic attack.” (10 seconds)

To combat attacks, she suggests:

“Changing respiration when noticing symptoms could be effective in avoiding a full blown panic attack. One should try to breathe as little air as possible, to reverse hyperventilation.’ (14 seconds)

Panic attacks that appeared to strike out of the blue were preceded for almost an hour by significant physiological changes that went undetected by research subjects in a study published in Biological Psychiatry. Panic attacks are intense episodes of terror lasting about 10 minutes that can be unexpected or induced by specific triggers. The disorder, which affects about six million American adults, is twice as common in women as men, according to the National Institute of Mental Health.

Researchers in Texas used portable monitors to record minute-by-minute physiological changes in 43 patients age 23 to 62 with moderate-to-severe panic disorder. Eight indicators, including heart rate, respiration, and skin conductance, an indication of a psychological or physiological reaction to stimuli, were measured during two 24-hour sessions. Patients pressed an event marker when a panic attack occurred and noted the start time. Thirteen attacks averaging eight minutes in length were reported.

The Atlantic: The Upside of a Panic Attack: The Worst Is Over Before You Know It

Science journalist Hans Villarica wrote about the groundbreaking panic attack research of SMU psychologists Dr. Alicia Meuret, Dr. David Rosenfield and Dr. Thomas Ritz in the The Atlantic.

There are plenty of misperceptions about panic attacks. People often tell the anxiety ridden to “take a deep breath,” for instance, when they may actually already be taking too much oxygen in by hyperventilating. Indeed, what experts say is that breathing should instead be slow, shallow, and regular, so that a constant, very small stream of air comes in through the nose. Paper bags are optional too, as cupped hands do the trick just as well.

New research aims to debunk another myth: Panic attacks occur completely out of the blue. Though those who panic don’t realize it, their attacks are in fact foreshadowed by minute physiological signals, according to a study led by Southern Methodist University’s Alicia Meuret in the journal Biological Psychiatry. “The hour before panic onset was marked by subtle but significant waves of changes in patient’s breathing and cardiac activity, not just the moment of onset of the attack or even during the attack,” she says. “Our analysis provided us with a whole different pattern.”

That pattern goes like this: Physiological instabilities occur in repeated bouts or waves and are often initiated by heart rate accelerations, followed by changes in breathing and carbon dioxide levels. Ultimately, breathing becomes much shallower, causing a spike in carbon dioxide levels that lead to symptoms that could no longer escape the attention of those who panic. More precisely, they experience terrifying sensations, such as dizziness, air hunger, and shortness of breath.
