Recording stress signals in children and young people with autism

Biophysiological Characterization of Stress in Autism Spectrum Disorders: Analysis of Peripheral Markers of the ANS and the HPA Axis

Observational Universite Cote d'Azur · NCT07535801

This project will see if stress-related body signals like heart rate changes and cortisol behave differently in children and young people with autism who have frequent behavioral crises compared with neurotypical peers.

What this trial studies

This observational project follows participants aged 3 to 22 to record physiological stress signals in everyday settings, focusing on the autonomic nervous system (for example heart rate variability) and the hypothalamic-pituitary-adrenal axis (for example cortisol). The study enrolls a group with autism and recurrent behavioral crises and a neurotypical control group to compare responses. Data are collected during real-life situations rather than only in the lab to capture natural stress reactions. The goal is to better characterize patterns that precede or accompany challenging behaviors in participants with limited communication.

Who should consider this trial

Good fit: Ideal participants are children and young people aged 3–22 with a clinical diagnosis of autism, recurrent behavioral crises (at least three episodes per week), enrolled in a participating care center, and with parental consent (and assent when appropriate).

Not a fit: Patients with known cardiac or hormonal disorders that interfere with physiological monitoring, those without frequent crises, or those unable to attend the participating site are unlikely to gain direct benefit from participation.

Why it matters

Potential benefit: If successful, the findings could help predict behavioral crises earlier and guide personalized support or interventions to reduce harm.

How similar studies have performed: Previous research has reported altered heart rate variability and cortisol responses in some people with autism but findings have been inconsistent and fewer studies have captured stress responses in real-life settings.
