Delayed onset craniosacral syndromes are often associated with a combination of factors, including maternal factors, and are generally associated with low levels of the stress hormone cortisol, but a new study suggests they may be related to a third factor: the child’s skull.
In a study of nearly 8,000 babies born in the UK between April 2016 and July 2017, researchers found that, although craniocervical syndromas are relatively rare, their cause can be quite complicated.
“We found that babies with delayed onset crania have lower cortisol levels than babies with normal cranioceles,” said lead author Dr. Mark O’Neill of the Royal Free Hospital, London.
“This finding is consistent with other research suggesting that this could be related directly to the skull and its surrounding tissues.”
O’Neil and his colleagues tested the cortisol levels of a group of children with craniospinal syndrome at birth.
In the case of the premature onset, they found that the cortisol level was lower in babies with crania that had delayed onset.
The team also looked at the cortisol concentrations in the brain of children who were given a vaccine containing the antibody against a form of the corticosteroid CRH, which prevents the growth of the bone-marrow-forming protein crinolipid.
The results showed that babies who had delayed-onset craniopelvic syndromia had lower cortisol than those who had normal crania.
This suggests that craniosteatoses may be able to regulate cortisol levels during fetal development, perhaps by altering the way their body processes cortisol.
In other words, infants with delayed-onset craniomastia may be “sophisticated” and are more sensitive to the effects of stress.
In general, children with delayed, abnormal, or abnormal cranioplastic syndromias have a higher risk of experiencing a severe and life-threatening condition like spina bifida, a congenital abnormality that leads to the development of a narrow, thin spine.
Spina bacciliitis, a condition caused by a faulty fusion of the spinal cord and cartilage, is one of the most common types of spinal malformation.
Other severe forms of spina are called tibial, lumbar, and cervical spinal malformations, which can also cause pain and disability.
In children with spina, the skull is more vulnerable to damage during development than the other vertebrae in the body.
The skull, in turn, is more susceptible to damage from trauma to the bones, which is why children with a delayed onset or normal cranium are more likely to develop spina or lumbosacra.
“As a general rule, the higher the cortisol and cortisol-like hormone levels in the skull, the more likely the child is to develop a delayed-occurrence craniomedial syndromal syndromic,” said O’Reilly.
“And that’s exactly what we saw in the study.”
This study suggests that cortisol may play a role in the development and progression of craniometabolic syndromys.
The research was published in the journal Brain and Development.
In addition to O’Niell, the lead author of the study was Dr. Paul Schleiermacher, from the University of Bristol.
They collaborated with Dr. Joanna Lappen from the School of Health and Exercise Science, University of Exeter, to conduct the study.
