The blink reflex in neonates with a subsequent poor outcome.
We examined maturational changes in the electrical blink reflex in 11 handicapped children, i.e., 4 cases of developmental delay, 4 of cerebral palsy, 2 of congenital hydrocephalus, and 1 of congenital cytomegalovirus infection. The developmental delay and cerebral palsy cases were all born at 25-36 weeks' gestation. In all cases, prolonged latency, low amplitude, or the absence of the late component of the blink reflex was observed in the follow-up study. These results indicate that prematurity and some congenital impairment mainly influence the maturation of the long-loop reflex arc in the blink reflex.
