Case Study: Antimanic Effectiveness of Dextroamphetamine in a Brain-Injured Adolescent

A relatively enduring and counterintuitive antimanic response to dextroamphetamine in a brain-injured adolescent who had failed trials involving divalproex, lithium, haloperidol, and carbamazepine is described. This finding combined with data from previous reports of antimanic effects of test doses of stimulants imply that such a pharmacological probe may prove relevant for the prediction of treatment response of mania to dextroamphetamine and perhaps for subclassification of bipolar disorder.

Social impairment and depression after traumatic brain injury

OBJECTIVE Previous studies have shown that social impairment is associated with major depression throughout the first year after traumatic brain injury (TBI). This study examined the specific social factors that were associated with post-TBI depression. METHOD A consecutive series of 65 patients with closed head injuries were cross-sectionally and longitudinally examined using a semistructured psychiatric interview, the Hamilton Depression Rating Scale, and the Social Functioning Exam during in-hospital care and at 3-, 6-, 9-, and 12-month follow-ups. RESULTS Depressed subjects showed poorer social functioning at the initial evaluation, and at 6, 9, and 12 months. Measures of preinjury job dissatisfaction and fear of job loss were significantly associated with depression at the initial evaluation. Concurrent impaired close personal relationships as well as continued fear of job loss were associated with depression at 6, 9, and 12 months after TBI. CONCLUSIONS These findings suggest that two of the psychosocial factors associated with depression during the acute TBI period (patients satisfaction with work and fear of job loss) are the same as those operant during the chronic period, but an additional psychosocial factor (close interpersonal relationships) is also operant during the chronic period. These findings support the need for early targeted social intervention in cases of TBI.

Cognitive outcome in children and adolescents following severe traumatic brain injury: influence of psychosocial, psychiatric, and injury-related variables

Previous studies of childhood traumatic brain injury (TBI) have emphasized injury-related variables rather than psychiatric or psychosocial factors as correlates of cognitive outcomes. We addressed this concern by recruiting a consecutive series (N = 24) of children age 5 through 14 years who suffered a severe TBI, a matched group who sustained a mild TBI, and a second matched group who sustained an orthopedic injury. Standardized intellectual, memory, psychiatric, family functioning, family psychiatric history, neurological, and neuroimaging assessments were conducted at an average of 2 years following injury. Severe TBI, when compared to mild TBI and orthopedic injury, was associated with significant decrements in intellectual and memory function. A principal components analysis of independent variables that showed significant (p < .05) bivariate correlations with the outcome measures yielded a neuropsychiatric factor encompassing severity of TBI indices and postinjury psychiatric disorders and a psychosocial disadvantage factor. Both factors were independently and significantly related to intellectual and memory function outcome. Postinjury psychiatric disorders added significantly to severity indices and family functioning and family psychiatric history added significantly to socioeconomic status in explaining several specific cognitive outcomes. These results may help to define subgroups of children who will require more intensive services following their injuries.

Adaptive functioning following traumatic brain injury and orthopedic injury: A controlled study

OBJECTIVE To study adaptive functioning after severe traumatic brain injury (TBI). DESIGN Case-control study. SETTING A university hospital and three regional and four community hospitals. SUBJECTS A consecutive series (n=24) of children age 5 through 14 years who suffered severe TBI were individually matched to subjects who sustained a mild TBI and to a second group who sustained an orthopedic injury with no evidence of TBI. MAIN OUTCOME MEASURES Standardized adaptive functioning, intellectual, psychiatric, and neuroimaging assessments were conducted on average 2 years after injury. RESULTS Severe TBI was associated with significantly (p < .05) lower Vineland Adaptive Behavior composite, communication, and socialization standard scores and lower Child Behavior Checklist parent-rated social competence scores compared with children with orthopedic injury. Severe TBI and mild TBI subjects were significantly (p < .05) more impaired than orthopedic subjects on teacher-rated adaptive function. Family functioning, psychiatric disorder in the child, and IQ were significant variables, explaining between 22% and 47% of the variance in adaptive functioning outcomes. CONCLUSIONS Severe TBI is associated with significant deficits in child adaptive functioning. This association appears to be mediated by family dysfunction, child psychiatric disorder, and intellectual deficits.

Posttraumatic stress symptomatology after childhood traumatic brain injury

The purpose of this study was to quantify and to identify predictors of posttraumatic stress disorder (PTSD) symptomatology after traumatic brain injury (TBI). Fifty children aged 6 to 14 years, hospitalized after TBI, were assessed soon after TBI regarding injury severity and preinjury psychiatric, socioeconomic, family functioning, and family psychiatric history status; neuroimaging was also analyzed. Psychiatric assessments were repeated 3, 6, 12, and 24 months after TBI. Only 2 of 46 (4%) subjects with at least one follow-up assessment developed PTSD. However, the frequency with which subjects experienced at least one PTSD symptom ranged from 68% in the first 3 months to 12% at 2 years in assessed children. The presence of an internalizing disorder at time of injury followed by greater injury severity were the most consistent predictors of PTSD symptomatology. It is apparent, therefore, that PTSD and subsyndromal posttraumatic stress disturbances occur despite neurogenic amnesia. These problems should be treated, particularly if symptoms persist beyond 3 months.

Case Study: Obsessive-Compulsive Disorder after Severe Traumatic Brain Injury in an Adolescent

The neurological underpinnings of obsessive-compulsive disorder (OCD) are still largely undetermined. We report a prospective case study of a young subject who developed OCD and impulsive aggression after traumatic brain injury. The implications are that frontal and temporal lobe lesions may be sufficient to precipitate OCD in the absence of clear striatal injury and that compulsivity and impulsivity may represent different psychophysiological states.

Oppositional defiant disorder symptomatology after traumatic brain injury: A prospective study

Our goal was to prospectively study the course of oppositional defiant disorder (ODD) symptomatology in children and adolescents in the first 2 years after traumatic brain injury (TBI). Fifty children aged 6 to 14, hospitalized after TBI, were assessed soon after TBI regarding injury severity; preinjury psychiatric, socioeconomic, family functioning, and family psychiatric history status; and neuroimaging was analyzed. ODD symptomatology in the first year after TBI was related to preinjury family function, social class, and preinjury ODD symptomatology. Increased severity of TBI predicted ODD symptomatology 2 years after injury. Change (from before TBI) in ODD symptomatology at 6, 12, and 24 months after TBI was influenced by socioeconomic status. Only at 2 years after injury was severity of injury a predictor of change in ODD symptomatology. The influence of psychosocial factors appears greater than severity of injury in accounting for ODD symptomatology and change in such symptomatology in the first but not the second year after TBI in children and adolescents. This appears related to persistence of new ODD symptomatology after more serious TBI.

The Neuropsychiatric Rating Schedule: reliability and validity.

OBJECTIVE To evaluate reliability and validity for the Neuropsychiatric Rating Schedule (NPRS) interview designed to permit diagnosis of organic personality syndrome (OPS) or personality change due to a general medical condition (PC). METHOD Subjects from prospective (n = 50) and retrospective (n = 72) studies of traumatic brain injury were aged 6 through 18 years. Parents and children were informants for the NPRS. Convergent and discriminant validity of subtypes of OPS/PC were assessed against standard scales completed by parents and teachers. Interrater reliability data (n = 20), test-retest reliability data (n = 42), as well as sensitivity-to-change data (n = 37) were collected. RESULTS All subtypes of OPS/PC were diagnosed, but apathy and paranoia subtypes were rare. Rating scale data supported convergent validity of OPS/PC subtypes generated with the NPRS. Affective instability, rage/aggression, and inappropriate social judgment were moderately to highly correlated, but apathy and paranoia could be discriminated from each of these subtypes. Interrater agreement for NPRS items was fair to excellent for all but one item (paranoia). Test-retest reliability was fair to good, and sensitivity to change was demonstrated. CONCLUSION The NPRS generated reliable and valid diagnoses of the common subtypes of OPS/PC.

Traumatic Brain Injury in a Child Psychiatry Inpatient Population: A Controlled Study

OBJECTIVE To extend our findings from child psychiatry outpatients to child psychiatry inpatients regarding the similarity of children with a history of traumatic brain injury (TBI), particularly mild TBI, to matched children without such a history. METHOD This is a chart review of patients consecutively admitted to a child psychiatry inpatient unit over a 5-year period. Children with TBI were matched by age, sex, race, and social class to children with no history of TBI. Axis I and II diagnoses and diagnostic clusters and use of special education services and IQ scores were compared. RESULTS Fifty-six (8.1%) of 694 consecutive patients admitted had a definite TBI. Not one of more than 50 variables compared between TBI and control subjects was significantly different. CONCLUSION In a child psychiatry inpatient unit, patients with a history of TBI were virtually indistinguishable from matched children without TBI. Caution should be exercised before attributing the childs problems, especially long-term problems, to the TBI unless the injury was severe or the child is exhibiting related phobic or posttraumatic stress symptomatology.

Traumatic Brain Injury in a Child Psychiatry Outpatient Clinic: A Controlled Study

OBJECTIVE To demonstrate the similarity of children with a history of traumatic brain injury (TBI), particularly mild TBI, to matched children without such a history, within a child psychiatry outpatient clinic. METHOD This is a chart review of patients presenting to a child psychiatry outpatient clinic over a 3-year period. Children with TBI were matched by age, sex, race, and social class to children with no history of TBI. Axis I and II diagnoses, use of special education services, and IQ scores were compared. RESULTS Seventy-four (5.6%) of 1,333 consecutive clinic cases had a definite TBI. Of these, 64 were mild. Only 3 of 59 comparisons that were made between TBI and control subjects were significant. A developmental communication disorder cluster was significantly more frequent in the TBI group. Autism and a pervasive developmental disorder cluster were significantly more frequent in the control group. CONCLUSION In a child psychiatry clinic, patients with a history of TBI are virtually indistinguishable from matched children without TBI. Caution should be exercised before attributing the childs problems, especially long-term problems, to the TBI unless the injury was severe or the child is exhibiting related phobic or posttraumatic stress symptomatology.
