Autism spectrum disorder in young patients with congenital central hypoventilation syndrome: role of the autonomic nervous system dysfunction.
One in twelve kids who needed a breathing machine at birth also has autism—watch long NICU time and sugar swings, then check heart-rate to spot who needs help fastest.
01Research in Context
What this study did
The team looked at the kids with congenital central hypoventilation syndrome (CCHS). They checked each child for autism and tracked NICU stay length, blood sugar problems, and heart-rate variability.
A short NICU stay and stable glucose meant lower autism odds. Low heart-rate variability (weak parasympathetic tone) was linked to poorer daily-living scores.
What they found
Eight point seven percent of CCHS patients also had ASD—about one in twelve. Longer ventilation in the newborn period and any glycemic swing doubled the chance of later ASD.
Kids with flatter heart-rate rhythms scored lower on communication, self-care, and social skills.
How this fits with other research
Modabbernia et al. (2016) pooled 67 studies and found that neonatal acidosis or low Apgar scores raise ASD odds. Wilson et al. (2024) now pinpoints CCHS as one specific high-risk group and names blood-sugar swings as a new marker.
Némorin et al. (2025) split 458 ASD toddlers into four profiles using symptom and adaptive scores. B et al. echo this move: they cluster CCHS kids by autonomic tone and show the same adaptive gap, just with a different ruler—heart-rate instead of behavior checklists.
Jokiranta et al. (2014) showed epilepsy rides along with ASD. B et al. swap epilepsy for autonomic failure but tell the same story: add a second brain system problem and daily skills drop further.
Why it matters
If you serve infants on long-term ventilation, flag any stay over two weeks or glucose roller-coaster for early autism screening. Track heart-rate variability during clinic visits—cheap, fast, and it warns you which kids may need stronger adaptive-skills programming. Pair your usual ABA assessment with a quick autonomic read and you can start communication or self-care goals sooner, before gaps widen.

<h4>Background</h4>Congenital central hypoventilation syndrome (CCHS) is a rare condition characterized by alveolar hypoventilation and autonomic nervous system (ANS) dysfunction requiring long-term ventilation. CCHS could constitute a risk factor of autism spectrum disorder (ASD) due to birth injury related to respiratory failure, which remains to be determined. ANS dysfunction has also been described in ASD and there are indications for altered contribution of ANS-central nervous system interaction in processing of social information; thus, CCHS could be a risk factor for ASD based on pathophysiological background also. Our study aimed to determine the prevalence of ASD among CCHS patients, identify risk factors, and explore the relationship between the ANS, evaluated by heart rate variability indices, and adaptative functioning.<h4>Results</h4>Our retrospective study, based on the analysis of records of a French national center of patients with CCHS under 20 years of age, determined that the prevalence of ASD (diagnosed by a psychiatrist, following the criteria of DSM-4 or DSM-5) was 6/69 patients, 8.7% (95% confidence interval: 3.3-18.0%). In a case (CCHS with ASD, n = 6) - control (CCHS without ASD, n = 12) study with matching on sex, longer neonatal hospitalization stay and glycemic dysfunction were associated with ASD. Adaptative functioning was assessed using Vineland Adaptative behavioral scales (VABS) and heart rate variability indices (including daytime RMSSD as an index of parasympathetic modulation) were obtained from ECG Holter performed the same day. In 19 young subjects with CCHS who had both ECG Holter and VABS, significant positive correlations were observed between RMSSD and three of four sub-domains of the VABS (communication: R = 0.50, p = 0.028; daily living skills: R = 0.60, p = 0.006; socialization: R = 0.52, p = 0.021).<h4>Conclusion</h4>Our study suggests a high prevalence of ASD in patients with CCHS. Glycemic dysfunction and longer initial hospitalization stays were associated with ASD development. A defect in parasympathetic modulation was associated with worse adaptative functioning.
