Bradley Ferguson analyzed the stress levels of eight adolescents who are severely affected by autism spectrum disorder at The Center for Discovery, a residential facility in New York that provides advanced care and research for individuals with complex conditions. Using wrist and ankle monitors, Ferguson found that there was a rise in the body’s electrodermal activity – which results from increased levels of sweat – 60% of the time before an individual showed behavioral issues.
‘Individuals affected by autism spectrum disorder have a hard time communicating their discomfort when they become stressed.’
“Individuals who are severely affected by autism spectrum disorder are often unable to verbally communicate their discomfort when they become stressed,” Ferguson said. “However, their body still responds to stressors, just like anyone else. Therefore, being alerted of increases in electrodermal activity can allow parents and caregivers to intervene prior to engagement in problem behavior with the goal of ensuring the health and safety of those involved.”
Ferguson collaborated on the study with David Beversdorf, a professor of radiology, neurology, and psychology in the MU College of Arts and Science as well as principal investigator of the Cognitive Neuroscience Laboratory in the MU School of Medicine. Ferguson also collaborated with Theresa Hamlin, Johanna Lantz, and Tania Villavicencio at The Center for Discovery, and John Coles at Calspan-University of Buffalo Research Center and The State University of New York at Buffalo.
“Important work is being done to try to identify predictors for when a person with autism is at greatest risk of having a behavioral episode,” Beversdorf said. “This research highlights the individual variability in this response that must be considered, and may also have implications for individualized treatment approaches moving forward.”
