Neuropsychological outcome was evaluated in a prospective, longitudinal follow-up study of children age 4 months to 7 years at injury with either mild-to-moderate (N = 35) or severe (N = 44) traumatic brain injury (TBI). Age-appropriate tests were administered at baseline, 6 months, 12 months, and 24 months after the injury. Performance was compared on (1)(More)
Children with congenital hydrocephalus, children with attention deficit-hyperactivity disorder, and normal controls were evaluated with measures of focused attention (Visual Orienting and Detection Task), sustained attention (continuous performance test), and attention shifting (Wisconsin Card Sorting Test). Components from these tasks have been linked to(More)
Although children with hydrocephalus frequently show poor development of nonverbal cognitive skills relative to verbal skills, little is known about the neuropathologic correlates of these discrepancies. In this study, cerebral white-matter structures and lateral ventricles were measured from the magnetic resonance images of age-matched children with(More)
Research on change is complicated by problems of measurement and analysis stemming from a conceptualization of change as a series of accumulating increments and decrements. In contrast, individual growth curves depict change as a continuous process underlying individual performance. These two perspectives are reviewed, and some problems with the use of(More)
Compared verbal and nonverbal skills of 65 children ages 5 to 7 years, with a history of shunted hydrocephalus (n = 26), arrested hydrocephalus (n = 11), and no hydrocephalus (n = 28), over a 5-year period. Comparison of these skills in 4 assessments revealed poorer average nonverbal than verbal skills on measures from the McCarthy Scales of Children's(More)
Examined the relationship of hydrocephalus and behavioral adjustment in three groups of 5- to 7-year-old children (N = 84) with a history of early hydrocephalus (spina bifida, prematurity, aqueductal stenosis) and three non-hydrocephalic comparison groups (spina bifida, prematurity, normals). Results revealed no significant group differences on measures of(More)
The effects of early hydrocephalus and related brain anomalies on cognitive skills are not well understood. In this study, magnetic resonance scans were obtained from 99 children aged from 6 to 13 years with either shunted hydrocephalus (n=42) or arrested (unshunted) hydrocephalus (n=19), from patient controls with no hydrocephalus (n=23), and from normal,(More)
Children with arrested, shunted, and no hydrocephalus were compared on verbal and nonverbal memory tasks assessing multiple components of memory. A gradient of severity was hypothesized, with the shunted hydrocephalus group expected to exhibit the most significant memory impairments and the arrested group expected to perform more poorly than children with(More)
Radiographic findings and related information are described for a series of 26 patients from six unrelated families. The tumor complex consists of a presacral teratoma and a sacrococcygeal bony defect occurring in a familial pattern. Many of the patients also had an associated vesicoureteral reflux, skin dimples, retrorectal abscess, and anorectal stenosis.(More)
