A newly published study in the journal Frontiers in Psychiatry titled 'A biomarker discovery framework for childhood anxiety' suggests that latent factors extracted from electroencephalogram (EEG) recordings in childhood are promising candidate biomarkers for anxiety disorders and for externalizing disorders. This study found that appropriate age was important - with accuracy improving up to seven years of age for anxiety and three to five years of age for externalizing disorders (primarily ADHD).
SAN FRANCISCO, Aug. 3, 2023 /PRNewswire-PRWeb/ -- A newly published study in the journal Frontiers in Psychiatry titled 'A biomarker discovery framework for childhood anxiety' suggests that latent factors extracted from electroencephalogram (EEG) recordings in childhood are promising candidate biomarkers for anxiety disorders and for externalizing disorders. This study found that appropriate age was important - with accuracy improving up to seven years of age for anxiety and three to five years of age for externalizing disorders (primarily ADHD). The study also suggests that anxiety emerges later than some other neurodevelopmental disorders.
The study was led by University of San Francisco (USF) Professor William Bosl, PhD, director of the USF Center for AI and Medicine and professor of Health Informatics, and co-first author Michelle Bosquet Enlow, PhD, together with colleagues at Harvard Medical School and Boston Children's Hospital, where Dr. Bosl holds affiliate faculty appointments.
"Until now, it's been widely accepted that anxiety disorders can only be effectively diagnosed after the emergence of clinical symptoms, which results in missed opportunities to intervene during critical formative periods," stated Bosl. "Our study shows that EEG recordings contain information about brain function that is useful for early detection of childhood anxiety disorders, creating new opportunities for early detection and intervention. Importantly, new technical advances will soon make EEG widely available as a low-cost, easy-to-administer, time-efficient brain measurement method that could be included in routine clinical practice, transforming opportunities for wide screening for risk and preventative intervention. With childhood anxiety disorders on the rise, these findings come at a critical time."
EEG recordings from two (5, 7 years) or three (3, 5, 7 years) sessions gave much better results than 7-year recordings alone, suggesting a developmental trajectory for anxiety disorders. However, the 7-year recordings were essential to detection. EEG recordings in the first year of life were not predictive of future anxiety outcomes.
The paper was co-authored by: Michelle Bosquet Enlow, PhD, Department of Psychiatry and Behavioral Sciences, Boston Children's Hospital, and Department of Psychiatry, Harvard Medical School Charles Nelson, PhD, director of the Laboratories of Cognitive Neuroscience at Boston Children's Hospital, the Department of Pediatrics at Harvard Medical School and the Harvard Graduate School of Education Eric F. Lock, PhD, Division of Biostatistics, School of Public Health, University of Minnesota
The study was supported by the National Institute of Mental Health (R01MH078829), the Koret Foundation through the University of San Francisco, the Tommy Fuss Center for Neuropsychiatric Disease Research, the Program for Behavioral Science, Department of Psychiatry and Behavioral Sciences, Boston Children's Hospital, and the National Institute of General Medical Sciences (R01GM130622).
