Brief report: parental report of sleep behaviors following moderate or severe pediatric traumatic brain injury

OBJECTIVE: Determine the effect of moderate and severe traumatic brain injuries (TBI) on the sleep of school-aged children. METHODS: A concurrent cohort-prospective design compared children aged 6-12 years who sustained moderate TBI (baseline n = 56), severe TBI (n = 53), or only orthopedic injuries (n = 80). Retrospective parental report of pre-injury sleep was collected about 3 weeks post-injury. Post-injury assessments occurred prospectively a mean of 6, 12, and 48 months later. RESULTS: Growth curve analyses compared the groups over time. The moderate TBI group had worse pre-injury sleep than the other groups. The moderate TBI and orthopedic injury groups displayed a small decline in sleep problems from pre- to post-injury. Children with severe TBI displayed increased post-injury sleep problems. CONCLUSIONS: Children who sustain severe TBI are at elevated risk for post-injury sleep problems. Because sleep problems may result in daytime impairments and family distress, additional clinical and research attention is warranted.     

An online family intervention to reduce parental distress following pediatric brain injury

This study examined whether an online problem-solving intervention could improve parental adjustment following pediatric traumatic brain injury (TBI). Families of children with moderate-to-severe TBI were recruited from the trauma registry of a large children's hospital and randomly assigned to receive online family problem solving therapy (FPS; n = 20) or Internet resources (IRC; n = 20) in addition to usual care. The FPS group reported significantly less global distress, depressive symptoms, and anxiety at follow-up than did the IRC group after controlling for baseline symptoms. The FPS group also reported significant improvements in problem-solving skills, although the groups did not differ significantly at follow-up. Findings suggest that an online, skill-building approach can be effective in facilitating parental adaptation after TBI.     

Long-term behavior problems following pediatric traumatic brain injury: prevalence,predictors, and correlates

OBJECTIVE: To study identified rates of long-term behavior problems in children with traumatic brain injury (TBI) compared to children with only orthopedic injuries and risk factors and correlates for new behavior problems following TBI. METHODS: Sample included children with severe TBI (n = 42), moderate TBI (n = 41), and orthopedic injuries only (ORTHO;n = 50). The baseline assessment measured child behavior, adaptation, and neuropsychological, academic, and family functioning. Follow-ups were conducted at 6 and 12 months and at an extended follow-up a mean of 4 years after injury. RESULTS: The prevalence of caseness, defined as elevated behavior problem ratings, was higher in one or both TBI groups than in the ORTHO group at each follow-up (e.g., 36% of severe TBI group, 22% of moderate TBI group, and 10% of ORTHO group at extended follow-up). Most instances of postinjury-onset caseness at the extended follow-up were evident within the first year after TBI. Predictors were severe TBI, socioeconomic disadvantage, and preinjury behavioral concerns. Concurrent correlates included weakness in working memory and adaptive behavior skills, poorer behavior and school competence, and adverse family outcomes. CONCLUSIONS: Postinjury-onset caseness is persistent, risks are multifactorial, and correlates include child dysfunction and family sequelae.     

Long-term parental and family adaptation following pediatric brain injury

OBJECTIVE: To determine whether parents of children with traumatic brain injuries (TBI) report increased injury-related burden, distress, and family dysfunction and to examine the effects of attrition on the results. METHODS: Children with severe TBI, moderate TBI, and orthopedic injuries were followed at six time points from baseline to 6 years after injury. Parents completed measures of injury-related burden, psychological distress, and family functioning at each assessment. Mixed model analysis was used to examine long-term changes. RESULTS: Attrition was higher among families in the severe TBI group with lower burden thereby amplifying group differences. The severe TBI group reported higher injury-related burden over time after injury than the other groups. Family functioning was moderated by social resources. Families of children with severe TBI and low resources reporting deteriorating functioning over the follow-up interval. CONCLUSIONS: Although environmental advantages moderate long-term effects on family functioning, families of children with severe TBI experience long-standing injury-related burden.     

Family burden and parental distress following mild traumatic brain injury in children and its relationship to post-concussive symptoms

OBJECTIVE: To examine the relationship of mild traumatic brain injuries (TBI) and post-concussive symptoms (PCS) to post injury family burden and parental distress, using data from a prospective, longitudinal study. METHODS: Participants included 71 children with mild TBI with loss of consciousness (LOC), 110 with mild TBI without LOC, and 97 controls with orthopedic injuries not involving the head (OI), and their parents. Shortly after injury, parents and children completed a PCS interview and questionnaire, and parents rated premorbid family functioning. Parents also rated family burden and parental distress shortly after injury and at 3 months post injury. RESULTS: Mild TBI with LOC was associated with greater family burden at 3 months than OI, independent of socioeconomic status and premorbid family functioning. Higher PCS shortly after injury was related to higher ratings of family burden and distress at 3 months. CONCLUSIONS: Mild TBI are associated with family burden and distress more than mild injuries not involving the head, although PCS may influence post injury family burden and distress more than the injury per se. Clinical implications of the current findings are noted in the Discussion section.     

Attention Deficit Hyperactivity Disorder in Children and Adolescents Following Traumatic Brain Injury

To better characterize pediatric psychopathology after neurological insult, secondary attention deficit hyperactivity disorder (SADHD)-or ADHD that develops after traumatic brain injury (TBI)-and its clinical and neuroimaging correlates were investigated. Outcome data were available for 118 children, ages 5 through 14 at the time of hospitalization following TBI (severe TBI n = 37; mild-moderate TBI n = 57) and orthopedic injury (n = 24). Standardized psychiatric, adaptive functioning, cognitive functioning, family functioning, and family psychiatric history assessments were conducted on all participants. Severity of injury and neuroimaging lesion assessments were conducted on TBI participants only. The diagnosis of SADHD was mutually exclusive with preinjury ADHD, which occurred in 13 of 94 TBI participants and 4 of 24 orthopedic injury participants. SADHD occurred in 13 of 34 eligible participants with severe TBI but resolved in 4 of 13 of these participants. SADHD also occurred in 1 of 8 eligible moderate TBI participants, only in the presence of preinjury ADHD traits and 3 of 39 of eligible mild TBI cases. SADHD occurred in 1 of 20 of eligible participants with orthopedic injury without any brain injury. SADHD was significantly associated with TBI severity recorded by categorical and dimensional measures, intellectual and adaptive functioning deficits, and personality change due to TBI, but not with lesion area or location. These results suggest that SADHD is a clinically important syndrome after severe TBI in children and adolescents.

Posttraumatic stress symptoms in children following orthopedic or traumatic brain injury

Examined posttraumatic stress (PTS) symptoms in children following pediatric traumatic brain injury (TBI). Children (ages 6-12) with TBI (n = 81) and orthopedic injury (01; n = 59) were assessed 6 and I2 months postinjury. Parents of children with severe TBI reported higher levels of child PTS symptoms than did parents of children with moderate TBI or 0 1 at the 6- and 12-month follow-ups. Group differences in child-reported PTS symptoms emerged at the 12-month follow-up with higher symptom levels reported by children with severe TBI than by those with moderate TBI or OI. At both follow-ups, rates of clinically significant symptom levels were higher in the severe TBI group than in the moderate TBI or OI groups. The group differences in parent and child reports were significant even after taking ethnicity, social disadvantage, and age at injury into account. Parent and child reports of child PTS symptoms were related to family socioeconomic status. Implications for clinical intervention with children and families following pediatric TBI are discussed.     

The relationship of caregiver coping to family outcomes during the initial year following pediatric traumatic injury

This study identified coping strategies associated with caregiver outcomes following pediatric injury and examined injury type as a moderator of coping efficacy. Families of 103 children with traumatic brain injury (TBI) and 71 children with orthopedic injuries were followed prospectively during the initial year postinjury. The groups had comparable preinjury characteristics and hospitalization experiences but differed on neurological insult. In hierarchical regression analyses, acceptance was associated with lower burden and denial was associated with greater distress in both groups. Active coping resulted in higher distress following TBI but not orthopedic injuries. Conversely, the use of humor was related to diminishing distress following TBI but unrelated to distress following orthopedic injuries. Results are discussed in terms of the implications for intervention following TBI.     

Race as a moderator of parent and family outcomes following pediatric traumatic brain injury

OBJECTIVE: To use data from a prospective, longitudinal study to determine whether race moderates parent and family outcomes during the first year following pediatric traumatic brain injuries (TBI). METHOD: Participants included 73 white and 18 black children with moderate to severe TBI and their families, and 32 white and 23 black children with orthopedic injuries only (OI) and their families. Assessments of parent and family functioning occurred shortly after injury (baseline) and at 6- and 12-month follow-ups. RESULTS: Race was a significant moderator of group differences in parental psychological distress and perceived family burden, by and large independent of socioeconomic status. The negative consequences of TBI were relatively less pronounced for parents of black children than for parents of white children at baseline, but became more pronounced at the two follow-ups. Black and white parents differed in preferred coping strategies, which may partially account for their different reactions to their children's injuries. CONCLUSIONS: The sociocultural factors associated with race may moderate the effects of pediatric TBI and OI on parents and families.     

The role of the family for behavioral outcome in children and adolescents following traumatic brain injury

This study assessed the behavioral outcome of 51 children with traumatic brain injury (TBI) up to 2 years following injury. Children with severe injuries, but not those with mild or moderate injuries, were reported by parents to have a greater incidence of behavior problems following TBI. Regression analyses indicated that the presence of a partner for the primary caregiver of the child and the acute emotional reaction of the parent to the injury were both predictive of child behavioral outcome, although not by 2-year follow-up. These findings suggest that parental coping resources may impact on the development of child behavioral sequelae following TBI, emphasizing the role of the family in the child's response and the importance of supportive intervention.     

A prospective study of short- and long-term outcomes after traumatic brain injury in children: behavior and achievement

Longitudinal behavior and achievement outcomes of traumatic brain injury (TBI) were investigated in 53 children with severe TBI, 56 children with moderate TBI, and 80 children with orthopedic injuries not involving brain insult. Measures of preinjury child and family status and of postinjury achievement skills were administered shortly after injury. Assessments were repeated 3 times across a mean follow-up interval of 4 years. Results from mixed model analysis revealed persisting sequelae of TBI. Recovery of math skills was observed in the severe TBI group but only for children from less stressed families. Social disadvantage in children with TBI predicted more adverse behavioral sequelae and less favorable changes in some outcome measures. The findings suggest that pediatric TBI has long-term effects on behavior and achievement but that postinjury progress is influenced by the family environment.     

Influences on first-year recovery from traumatic brain injury in children

This study examined recovery over the first year following traumatic brain injury (TBI) in children 6-12 years of age. Forty-two children with severe TBI and 52 with moderate TBI were compared to 58 children with orthopedic injuries. The children and their families were evaluated at a baseline assessment and at 6- and 12-month follow-ups. Findings documented cognitive, achievement, and behavioral sequelae of TBI, with only limited evidence for recovery over the first year postinjury. Outcomes were predicted by preinjury factors, TBI severity, and measures of the postinjury family environment. Some of the sequelae of severe TBI were more marked in the context of higher compared with lower levels of family burden or dysfunction. The findings confirm the need to consider environmental contributions to outcomes of TBI in children.     

Recovery of Working Memory Following Pediatric Traumatic Brain Injury: A Longitudinal Analysis

In a prospective longitudinal study, the trajectory of verbal and visual-spatial working memory (WM) development was examined 2-, 6-, 12-, and 24-months following complicated-mild to severe pediatric traumatic brain injury (TBI; n = 55) relative to an orthopedic injury comparison group (n = 47). Individual growth curve modeling revealed an interaction of age, severity, and time for verbal, but not visual-spatial WM. The youngest children with severe TBI had the lowest scores and slowest verbal WM growth. WM outcome is best understood in light of age at injury and TBI severity. Findings support the early vulnerability hypothesis and highlight the need for long-term follow-up.     

Sleep disturbances following mild traumatic brain injury in childhood

OBJECTIVE: To examine objective and subjective reports of sleep disturbance in school-aged children who had sustained mild traumatic brain injury (TBI) at least 6 months prior to the study. METHODS: Eighteen children aged 7-12 years with a history of mild TBI (GCS 13-15. LOC < 15 min) were compared to 30 children with orthopedic injuries using actigraphy and parental and self-report sleep questionnaires. RESULTS: Parents reported greater sleep disturbance in the mild TBI group. No significant differences were found in parental ratings of daytime sleepiness, child-reported sleep difficulties, or objective (actigraph) sleep measures. CONCLUSIONS: The finding of greater parental reports of sleep disturbance following mild TBI 6 months after injury requires greater exploration and future research with a larger sample followed from the point of injury would seem appropriate.     

Mental State Attributions and Diffusion Tensor Imaging After Traumatic Brain Injury in Children

We studied social cognition in 49 children 3 months after moderate to severe traumatic brain injury (TBI) and in 39 children with orthopedic injury (OI). Children underwent diffusion tensor imaging (DTI) and a mental attribution task showing two triangles. Mental state attributions increased when one triangle reacted to intentions of the other, but less so in the TBI than the OI group. DTI identified injury to white matter microstructure in the TBI group, but the relation of DTI to mental attributions did not differ between groups. Moderate to severe TBI produces white matter disconnections that may affect social cognitive networks.

Modeling of Longitudinal Academic Achievement Scores After Pediatric Traumatic Brain Injury

In a prospective longitudinal study, academic achievement scores were obtained from youth 5 to 15 years of age who sustained mild-moderate (n = 34) or severe (n = 43) traumatic brain injuries (TBI). Achievement scores were collected from baseline to 5 years following TBI and were subjected to individual growth curve analysis. The models fitted age at injury, years since injury, duration of impaired consciousness, and interaction effects to Reading Decoding, Reading Comprehension, Spelling, and Arithmetic standard scores. Although scores improved significantly over the follow-up relative to normative data from the standardization sample of the tests, children with severe TBI showed persistent deficits on all achievement scores in comparison to children with mild-moderate TBI. Interactions of the slope and age parameters for the Arithmetic and Reading Decoding scores indicated greater increases over time in achievement scores of the children injured at an older age, but deceleration in growth curves for the younger children with both mild-moderate and severe TBI. These results are compatible with the hypothesis that early brain injuries disrupt the acquisition of some academic skills. Hierarchical regression models revealed that indexes of academic achievement obtained 2 years following TBI had weak relations with the duration of impaired consciousness and socioeconomic status. In contrast, concurrent cognitive variables such as phonological processing and verbal memory accounted for more variability in academic scores. Given the significant and persistent decrement in basic academic skills in youth with severe TBI, it is clear that head-injured youth require intensive, long-term remediation and intervention not only of the academic skills themselves, but also of those cognitive abilities that support the development and maintenance of reading and math.
