Child and Infant Learning Project

In the first phase of this multi-site, 10-year longitudinal study, infants with one of four
types of single-suture craniosynostosis were recruited: sagittal, metopic, right unilateral
coronal, and left unilateral coronal. A case-matched "control" group of healthy, normal
infants was also followed. This study, which is now in its second phase, is following this
same cohort of children at the age of 7 years.

Enrollment criteria at Phase 1:

- Confirmed diagnosis of single-suture, nonsyndromic craniosynostosis (sagittal,
metopic, unilateral coronal, or lambdoid)

- Corrective (cranioplastic) surgery not yet performed

- Child born at 34 weeks gestation or later

- Absence of neurological conditions/significant health problems

- 33 months or younger at time of enrollment (male or female).

Enrollment criteria at Phase 2:

All participants enrolled in phase 1 are invited to participate in phase 2.
