Functional Recovery During Inpatient Rehabilitation in Children With Anoxic or Hypoxic Brain Injury.

OBJECTIVES: To (1) describe characteristics of children with anoxic or hypoxic brain injuries (AnHBI) who presented to an inpatient rehabilitation unit, (2) explore functional outcomes of children with AnHBI at discharge, and (3) examine differences between children with AnHBI associated with cardiac arrest (CA) vs those with respiratory arrest (RA) only. DESIGN: Retrospective cohort study. SETTING: Pediatric inpatient rehabilitation hospital in the Northeast United States. PARTICIPANTS: A total of 46 children and adolescents ages 11 months to 18 years admitted to an inpatient rehabilitation brain injury unit (1994-2018) for a first inpatient admission after AnHBI. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Pediatric Cerebral Performance Category Scale (PCPC), Pediatric Overall Performance Category, and Functional Independence Measure for Children developmental functional quotients (WeeFIM DFQs) total and subscale scores. RESULTS: Most children had no disability before injury (PCPC=normal, n=37/46) and displayed significant functional impairments at admission to inpatient rehabilitation (PCPC=normal/mild, n=1/46). WeeFIM and PCPC scores improved significantly during inpatient rehabilitation (WeeFIM DFQ Total, P=.003; PCPC, P<.001), although many children continued to demonstrate significant impairments at discharge (PCPC=normal/mild, n=5/46). Functioning was better for the RA-only group relative to the CA group at admission (WeeFIM DFQ Total, P=.006) and discharge (WeeFIM DFQ Total, P<.001). Ongoing gains in functioning were noted 3 months after discharge compared with discharge (WeeFIM DFQ Cognitive, P=.008). CONCLUSIONS: In this group of children with AnHBI who received inpatient rehabilitation, functional status improves significantly between rehabilitation admission and discharge. By discharge, many children continued to display significant impairments, a minority of children had favorable neurologic outcomes, and children with CA have worse outcomes than those with RA-only. Given the small sample size, future research should examine functional recovery during inpatient rehabilitation in a larger, multisite cohort and include longer-term follow-up to examine recovery patterns over time.

Emergence to the conscious state during inpatient rehabilitation after traumatic brain injury in children and young adults: a case series.

OBJECTIVE: To describe clinical patterns related to emergence to the conscious state (CS) in children and young adults with traumatic brain injury receiving acute inpatient rehabilitation. SETTING: One academically affiliated pediatric brain injury rehabilitation unit. PARTICIPANTS: Fourteen consecutive patients aged 1 to 20 years with traumatic brain injury and disorders of consciousness. DESIGN: Retrospective case series. MAIN MEASURES: The primary outcome was emergence to CS during the inpatient rehabilitation admission. Factors evaluated for relationship to emergence to CS included age at injury, admission level of consciousness, admission Rappaport Coma/Near-Coma Scale score, and admission Cognitive and Linguistic Scale responsiveness item score. RESULTS: Ten of 14 patients emerged to CS during the inpatient rehabilitation admission. Those who emerged to CS had higher levels of responsiveness at admission to rehabilitation. There was a trend toward older age in those who emerged to CS. CONCLUSIONS: In this limited cohort, the majority of patients with disorders of consciousness after traumatic brain injury emerged to CS during acute inpatient rehabilitation, underscoring the presence of functional goals for inpatient rehabilitation in this population. Larger cohorts are needed to further explore clinical variables associated with emergence to CS.

Examining acute rehabilitation outcomes for children with total functional dependence after traumatic brain injury: a pilot study.

OBJECTIVE: To examine in a pilot cohort factors associated with functional outcome at discharge and 3-month follow-up after discharge from inpatient rehabilitation in children with severe traumatic brain injury (TBI) who entered rehabilitation with the lowest level of functional skills. PARTICIPANTS: Thirty-nine children and adolescents (3-18 years old) who sustained a severe TBI and had the lowest possible rating at rehabilitation admission on the Functional Independence Measure for Children (total score = 18). METHODS: Retrospective review of data collected as part of routine clinical care. RESULTS: At discharge, 59% of the children were partially dependent for basic activities, while 41% remained dependent for basic activities. Initial Glasgow Coma Scale score, time to follow commands, and time from injury to rehabilitation admission were correlated with functional status at discharge. Time to follow commands and time from injury to rehabilitation admission were correlated with functional status at 3-month follow-up. Changes in functional status during the first few weeks of admission were associated with functional status at discharge and follow-up. CONCLUSIONS: Even children with the most severe brain injuries, who enter rehabilitation completely dependent for all daily activities, have the potential to make significant gains in functioning by discharge and in the following few months. Assessment of functional status early in the course of rehabilitation contributes to the ability to predict outcome from severe TBI.

The association between sleep disordered breathing, academic grades, and cognitive and behavioral functioning among overweight subjects during middle to late childhood.

STUDY OBJECTIVES: (1) to determine the associations of sleep disordered breathing (SDB) with behavioral functioning, cognitive test scores, and school grades during middle- to late-childhood, an under-researched developmental period in the SDB literature, and (2) to clarify whether associations between SDB and school grades are mediated by deficits in cognitive or behavioral functioning. DESIGN: cross-sectional correlative study. SETTING: Office/hospital, plus reported functioning at home and at school. PARTICIPANTS: 163 overweight subjects aged 10-16.9 years were divided into 4 groups based upon their obstructive apnea+hypopnea index (AHI) during overnight polysomnography and parent report of snoring: Moderate-Severe OSA (AHI > 5, n = 42), Mild OSA (AHI = 1-5, n = 58), Snorers (AHI < 1 + snoring, n = 26), and No SDB (AHI < 1 and nonsnoring, n = 37). MEASUREMENTS: inpatient overnight polysomnography, parent- and self-report of school grades and sleep, parent- and teacher-report of daytime behaviors, and office-based neuropsychological testing. RESULTS: The 4 groups significantly differed in academic grades and parent- and teacher-reported behaviors, particularly inattention and learning problems. These findings remained significant after adjusting for subject sex, race, socioeconomic status, and school night sleep duration. Associations with SDB were confined to reports of behavioral difficulties in real-world situations, and did not extend to office-based neuropsychological tests. Findings from secondary analyses were consistent with, but could not definitively confirm, a causal model in which SDB affects school grades via its impact on behavioral functioning. CONCLUSIONS: SDB during middle- to late-childhood is related to important aspects of behavioral functioning, especially inattention and learning difficulties, that may result in significant functional impairment at school.

Long-term neural processing of attention following early childhood traumatic brain injury: fMRI and neurobehavioral outcomes.

Attentional deficits are common and significant sequelae of pediatric traumatic brain injury (TBI). However, little is known about how the underlying neural processes that support different components of attention are affected. The present study examined brain activation patterns using fMRI in a group of young children who sustained a TBI in early childhood (n = 5; mean age = 9.4), and a group of age-matched control children with orthopedic injuries (OI) (n = 8) during a continuous performance task (CPT). Four children in the TBI group had moderate injuries, and one had a severe injury. Performance on the CPT task did not differ between groups. Both TBI and OI children activated similar networks of brain regions relevant to sustained attention processing, but the TBI group demonstrated several areas of significantly greater activation relative to controls, including frontal and parietal regions. These findings of over-activation of the relevant attention network in the TBI group contrast with those obtained in imaging studies of Attention-Deficit/Hyperactivity Disorder where under-activation of the attention network has been documented. This study provides evidence that young children's brains function differently following a traumatic brain injury, and that these differences persist for years after the injury.

Neural correlates of verbal associative memory and mnemonic strategy use following childhood traumatic brain injury.

Children with traumatic brain injury (TBI) often experience memory deficits, although the nature, functional implication, and recovery trajectory of such difficulties are poorly understood. The present fMRI study examined the neural activation patterns in a group of young children who sustained moderate TBI in early childhood (n = 7), and a group of healthy control children (n = 13) during a verbal paired associate learning (PAL) task that promoted the use of two mnemonic strategies differing in efficacy. The children with TBI demonstrated intact memory performance and were able to successfully utilize the mnemonic strategies. However, the TBI group also demonstrated altered brain activation patterns during the task compared to the control children. These findings suggest early childhood TBI may alter activation within the network of brain regions supporting associative memory even in children who show good behavioral performance.
