Abstract
It has been argued that young children's brains
are “plastic,” and may sustain substantial
brain insult with little loss of function. Recent research
suggests that this notion may not apply for generalized
cerebral pathology. The present study aimed to evaluate
this proposition using a sample of 73 young children, divided
into 3 groups: severe head injury (HI; N
= 17); mild–moderate HI (N = 32);
and noninjured controls (N = 24). Preinjury screening
established equivalence across groups for age, sex, preinjury
ability, behavioral adjustment, socioeconomic status, and
family functioning. Children were evaluated as soon as
possible postinjury, and again 12 months postinjury, in
three domains: intellectual ability, language, and memory.
Results indicated that severe HI was associated with substantial,
persisting difficulties in all areas. In contrast, children
with mild–moderate HI experienced fewer difficulties,
and often performed similarly to controls, both acutely
and 12 months postinjury. There was no evidence of differential
recovery of function associated with injury severity, with
performance increments consistent across groups and probably
due to either age-appropriate developmental gains, or test–related
practice effects. Poorer outcome at 12 months postinjury
was predicted by injury severity primarily, with earlier
age at injury, and premorbid ability associated with outcome
in specific domains. (JINS, 1997, 3,
