title: Residual developmental disabilities in children with transient hypertonicity in infancy.
abstract: Developmental disabilities occurred in children who manifested transient neurologic abnormalities in early infancy. In an attempt to identify associated problems at an earlier age, the neuromotor and developmental progress of 33 children who had transient hypertonicity during early infancy was analyzed. At 2-3 years of age, various developmental abnormalities were identified in more than two-thirds of these children. Delays in speech and language development and also in fine motor/adaptive and behavioral difficulties were most frequently present. Over time, these problems persisted and other disorders also became apparent. At 5 years of age or older, learning disabilities were frequent and associated with language and perceptual problems. None of the patients had epilepsy; mental retardation was present in only 2 children. Our study demonstrates that children with transient hypertonicity in early infancy are at risk for various developmental problems which can be identified as early as 2 years of age. It also indicates that although their severity lessens over time, these developmental abnormalities tend to persist.
