What is Craniosynostosis?
Craniosynostosis is a birth defect of the brain characterized by the premature closure of one or more of the fibrous joints between the bones of the skull (called the cranial sutures) before brain growth is complete. Closure of a single suture is most common. The abnormally shaped skull that results is due to the brain not being able to grow in its natural shape because of the closure. Instead it compensates with growth in areas of the skull where the cranial sutures have not yet closed. The condition can be gene-linked, or caused by metabolic diseases, such as rickets or an overactive thyroid. Some cases are associated with other disorders such as microcephaly (abnormally small head) and hydrocephalus (excessive accumulation of cerebrospinal fluid in the brain). The first sign of craniosynostosis is an abnormally shaped skull. Other features can include signs of increased intracranial pressure, developmental delays, or mental retardation, which are caused by constriction of the growing brain. Seizures and blindness may also occur.

Is there any treatment?
Treatment for craniosynostosis generally consists of surgery to relieve pressure on the brain and the cranial nerves. For some children with less severe problems, cranial molds can reshape the skull to accommodate brain growth and improve the appearance of the head.

What is the prognosis?
The prognosis for craniosynostosis varies depending on whether single or multiple cranial sutures are involved or other abnormalities are present. The prognosis is better for those with single suture involvement and no associated abnormalities.

What research is being done?
The NINDS conducts and supports a wide range of studies that explore the complex mechanisms of early neurological development. The knowledge gained from these fundamental studies provides the foundation for understanding how this process can go awry and offers hope for new ways to treat and prevent brain birth defects, including craniosynostosis.
