This study looked at the use of head circumference and head tilting reflex as two biomarkers that can be used during their well - baby visits by their primary care providers.

At the end of nine months, those infants with a head circumference above or equal to the 75th percentile, a head circumference that was in 10 percent discrepancy with the height of the baby, or those who failed the head tilting reflex test were considered at risk for ASD or a developmental language delay.

This study looked at the use of head circumference and head tilting reflex as two biomarkers that can be used during well - baby visits by primary care providers.

«We will continue looking at the efficacy of the head circumference and head tilting reflex as a screening tool for these disorders,» said Andrea Gropman, MD, a contributor to the study and Division Chief of Neurogenetics at Children's National.

Researchers, including a team from Children's National Health System, have identified head circumference and head tilting reflex as two reliable biomarkers in the identification of autism spectrum disorders (ASD) in children that are between 9 and 12 months of age.

In animal models, exposure to cigarette smoke or nicotine during fetal development alters the expression of the nicotinic acetylcholine receptor in areas of the brainstem important for autonomic function, 28 alters the neuronal excitability of neurons in the nucleus tractus solitarius (a brainstem region important for sensory integration), 29 and alters fetal autonomic activity and medullary neurotransmitter receptors.30 In human infants, there are strong associations between nicotinic acetylcholine receptor and serotonin receptors in the brainstem during development.31 Prenatal exposure to tobacco smoke attenuates recovery from hypoxia in preterm infants, 32 decreases heart rate variability in preterm33 and term34 infants, and abolishes the normal relationship between heart rate and gestational age at birth.33 Moreover, infants of smoking mothers exhibit impaired arousal patterns to trigeminal stimulation in proportion to urinary cotinine levels.35 It is important to note also that prenatal exposure to tobacco smoke alters the normal programming of cardiovascular reflexes such that there is a greater - than - expected increase in blood pressure and heart rate in response to breathing 4 % carbon dioxide or a 60 ° head - up tilt.36 These changes in autonomic function, arousal, and cardiovascular reflexes might all increase an infant's vulnerability to SIDS.
