Social cognition impairments can contribute to social participation difficulties following traumatic brain injury (TBI). However, little attention has been given to these impairments during adolescence, a period of life when peer relationships are central. The aim of the current study was to examine the impact of a moderate to severe TBI sustained in adolescence on multiple facets of social cognition. Twenty-three adolescents who had sustained a moderate-to-severe TBI were compared with a group of 23 typically developing peers. The Integrated Social Cognition Battery (mentalising, social knowledge, emotion recognition) and the Interpersonal Reactivity Index were administered, along with non-social cognition tests (selective attention, working memory, executive functions), IQ estimation, and a socio-demographic questionnaire. Adolescents with TBI reported having a significantly lower ability to take other people's perspectives versus controls. They also presented significantly lower levels of mentalising. After controlling for non-social higher-order cognitive variables, the group effect on mentalising remained marginally significant, whereas the effect on perspective taking remained significant. Our findings suggest the presence of primary deficits in social cognition following TBI in adolescence. These deficits could partially underlie the social reintegration difficulties encountered following TBI. A systematic assessment of social cognition in clinical practice is necessary. 相似文献

Pediatric traumatic brain injury (TBI) can result in a range of social impairments, however longitudinal recovery is not well characterized, and clinicians are poorly equipped to identify children at risk for persisting difficulties. Using a longitudinal prospective design, this study aimed to evaluate the contribution of injury and non-injury related risk and resilience factors to longitudinal outcome and recovery of social problems from 12- to 24-months post-TBI. 78 children with TBI (injury age: 5.0–15.0 years) and 40 age and gender-matched typically developing (TD) children underwent magnetic resonance imaging including a susceptibility-weighted imaging (SWI) sequence 2–8 weeks post-injury (M = 39.25, SD = 27.64 days). At 12 and 24-months post- injury, parents completed questionnaires rating their child’s social functioning, and environmental factors including socioeconomic status, caregiver mental health and family functioning. Results revealed that longitudinal recovery profiles differed as a function of injury severity, such that among children with severe TBI, social problems significantly increased from 12- to 24-months post-injury, and were found to be significantly worse than TD controls and children with mild and moderate TBI. In contrast, children with mild and moderate injuries showed few problems at 12-months post-injury and little change over time. Pre-injury environment and SWI did not significantly contribute to outcome at 24-months, however concurrent caregiver mental health and family functioning explained a large and significant proportion of variance in these outcomes. Overall, this study shows that longitudinal recovery profiles differ as a function of injury severity, with evidence for late-emerging social problems among children with severe TBI. Poorer long-term social outcomes were associated with family dysfunction and poorer caregiver mental health at 24-months post injury, suggesting that efforts to optimize the child’s environment and bolster family coping resources may enhance recovery of social problems following pediatric TBI. 相似文献

Previous studies have reported a dissociation between social behavioral impairments after severe traumatic brain injury (TBI) and relatively preserved performances in traditional tasks that investigate cognitive abilities. Theory of mind (ToM) refers to the ability to make inferences about other's mental states and use them to understand and predict others' behavior. We tested a group of 15 patients with severe TBI and 15 matched controls on a series of four verbal and non-verbal ToM tasks: the faux pas test, the first-order and second-order false belief task, the character intention task and the Reading the Mind in the Eyes Test. Participants with severe TBI were also compared to controls on non-ToM inference tasks of indirect speech act from the Montreal Evaluation of Communication (M.E.C.) Protocol and empathy (Davis Interpersonal Reactivity Index - I.R.I.) and tests for executive functions. Subjects with TBI performed worse than control subjects on all ToM tasks, except the first-order false belief task. The findings converge with previous evidence for ToM deficit in TBI and dissociation between ToM and executive functions. We show that ToM deficit is probably distinct from other aspects of social cognition like empathy and pragmatic communication skills. 相似文献

PurposeAlthough many patients with schizophrenia are impaired in mental states attribution abilities, a significant number perform within normal or near-normal ranges in mental state attribution tasks. No studies have analysed cognitive or behavioural differences between patients with – to some extent – preserved mental state attribution skills and those with poor mentalising abilities.Material and methodsTo examine characteristics of “poor” and “fair” mentalisers, 58 patients with schizophrenia performed a mental state attribution task, a test of general intelligence, and two executive functioning tests. “Poor” and “fair” mentalising skills were defined according to a median-split procedure; the median score in the patient group was also within two standard deviations of the control group. In addition, patients’ social behavioural skills and psychopathological profiles were rated.ResultsPatients performing within normal or near normal ranges on the mental state attribution task had fewer social behavioural abnormalities than patients with poor mentalising abilities (even when controlled for intelligence), but did not differ in executive functioning. Fair mental state performers showed less disorganisation and excitement symptoms than poor performers. The degree of disorganisation mediated the influence of mental state attribution on social behavioural skills.ConclusionsSchizophrenia patients with (partially) preserved mentalising skills have fewer behavioural problems in the social domain than patients with poor mentalising abilities. Conceptual disorganisation mediates the prediction of social behavioural skills through mentalising skills, suggesting that disorganised patients may require special attention regarding social-cognitive skills training. 相似文献

The purpose of the present study was to investigate two theoretical frameworks for understanding acquired deficits in social behavior in individuals with severe traumatic brain injury (TBI). Recent research has found that brain injury can lead to impairments in implicit processes including social cognition. Impairments in implicit social cognition have been recently advanced as an explanation for acquired social deficits, as implicit social cognition is hypothesized to mediate the processing and understanding of often subtle, nonverbal cues in social interactions. In contrast, the executive dysfunction account posits that deficits in higher order cognitive functions, such as attention, planning ability, and mental flexibility, are the locus for acquired deficits in social cognition and behavior. To test these two theories, 22 participants with severe TBI and 25 matched controls were administered a measure of implicit social cognition (Implicit Association Test, IAT), as well as two measure of explicit social attitudes and a range of executive functioning measures. The TBI participants were found to perform normally on the IAT and explicit measures of gender stereotyping but demonstrated executive deficits. Performance on the IAT and executive functions were correlated. Performance in general did not fit well with the implicit social cognition explanation for social dysdecorum following TBI. More evidence was found to support the executive account. 相似文献

Alterations in cerebrovascular function are evident acutely in moderate to severe traumatic brain injury (TBI), although less is known about their chronic effects. Adolescent and adult patients with moderate to severe TBI have been reported to demonstrate diffuse activation throughout the brain during functional magnetic resonance imaging (fMRI). Because fMRI is a measure related to blood flow, it is possible that any deficits in blood flow may alter activation. An arterial spin labeling (ASL) perfusion sequence was performed on seven adolescents with chronic moderate to severe TBI and seven typically developing (TD) adolescents during the same session in which they had performed a social cognition task during fMRI. In the TD group, prefrontal CBF was positively related to prefrontal activation and negatively related to non-prefrontal, posterior, brain activation. This relationship was not seen in the TBI group, who demonstrated a greater positive relationship between prefrontal CBF and non-prefrontal activation than the TD group. An analysis of CBF data independent of fMRI showed reduced CBF in the right non-prefrontal region (p<.055) in the TBI group. To understand any role reduced CBF may play in diffuse extra-activation, we then related the right non-prefrontal CBF to activation. CBF in the right non-prefrontal region in the TD group was positively associated with prefrontal activation, suggesting an interactive role of non-prefrontal and prefrontal blood flow throughout the right hemisphere in healthy brains. However, the TBI group demonstrated a positive association with activation constrained to the right non-prefrontal region. These data suggest a relationship between impaired non-prefrontal CBF and the presence of non-prefrontal extra-activation, where the region with more limited blood flow is associated with activation limited to that region. In a secondary analysis, pathology associated with hyperintensities on T2-weighted FLAIR imaging over the whole brain was related to whole brain activation, revealing a negative relationship between lesion volume and frontal activation, and a positive relationship between lesion volume and posterior activation. These preliminary data, albeit collected with small sample sizes, suggest that reduced non-prefrontal CBF, and possibly pathological tissue associated with T2-hyperintensities, may provide contributions to the diffuse, primarily posterior extra-activation observed in adolescents following moderate to severe TBI. 相似文献

A number of studies have now documented that traumatic brain injury (TBI) is associated with deficits in the recognition of basic emotions, the capacity to infer mental states of others (theory of mind), as well as executive functioning. However, no study to date has investigated the relationship between these three constructs in the context of TBI. In the current study TBI participants (N=16) were compared with demographically matched healthy controls (N=17). It was found that TBI participants' recognition of basic emotions, as well as their capacity for mental state attribution, was significantly reduced relative to controls. Performance on both of these measures was strongly correlated in the healthy control, but not in the TBI sample. In contrast, in the TBI (but not the control) sample, theory of mind was substantially correlated with performance on phonemic fluency, a measure of executive functioning considered to impose particular demands upon cognitive flexibility and self-regulation. These results are consistent with other evidence indicating that deficits in some aspects of executive functioning may at least partially underlie deficits in social cognition following TBI, and thus help explain the prevalence of social dysfunction in TBI. 相似文献

Objective: Examination of social cognition as a target for assessment and intervention is beginning to gain momentum in a number of illnesses and acquired disorders. One facet of social cognition is decision making within interpersonal situations. This skill forms an important part of our everyday lives and is commonly impaired in those with neurological and mental health conditions. A novel task was developed to allow the assessment of decision making specifically within a social context and was examined within a group known to experience this difficulty. Method: Participants with severe traumatic brain injury (TBI) were compared to healthy control participants on the Social Decision Making Task (SDMT), which required the participant to learn who the “friendly” players were in a game of toss. Participants also completed a nonsocial decision-making task, the Iowa Gambling Task (IGT) as well as a battery of neuropsychological tests and social cognition tasks. Current social functioning was also examined. Results: Consistent with predictions, the TBI group made poorer decisions on the SDMT than the control group; however, group differences were not evident on the IGT. No significant relationships were observed between the SDMT and either measures of executive functioning (including working memory and reversal learning) or social cognition (including emotion recognition and theory of mind). Performance on the SDMT and the IGT were not associated, suggesting that the two tasks measure different constructs. Conclusions: The SDMT offers a novel way of examining decision making within a social context following TBI and may also be useful in other populations known to have specific social cognition impairment. Future research should aim to provide further clarification of the mechanisms of action and neuroanatomical correlates of poor performance on this task. 相似文献

BackgroundA wide variety of psychiatric conditions are associated with social cognitive deficits. The relationship between social cognition and many factors, especially executive functions (EF), has been examined, but there is no study examining sleep and social cognition in children with attention deficit activity disorder (ADHD). It is important to find new approaches and intervention areas to improve their social cognitive skills. The main hypothesis of our study was that sleep disturbance would predict lower social cognition scores. We hypothesized that sleep disturbances and EF impairment could predict lower social cognitive performance.MethodsEighty-five children aged 7–12 years with drug-naïve ADHD were included in the study. Reading the Mind in the Eyes Test (RMET) and Faux Pas Recognition Test (FPRT) were used for social cognition performance; Stroop test was used for executive function performance. Sleep disturbance was evaluated with Children's Sleep Habits Questionnaire (CSHQ), ADHD severity with Conners Parent Rating Scale (CPRS). Hierarchical multiple regression analyses were performed to determine predictive factors of the FPRT and RMET.ResultsAge, gender, and comorbidity were included at step 1, CPRS-RS score was included at step 2, Stroop test part V score was included at step 3, CSHQ total score and sleep duration were included at step 4. Lower sleep disturbance score on CSHQ was associated with higher social cognition FPRT score (p = 0.014). There was no significant relationship between CSHQ and social cognition RMET score. Lower EF score on Stroop test part V was associated with higher social cognition FPRT score (p = 0.002) and higher social cognition RMET score (p < 0.001).ConclusionThese results showed that sleep disturbance and EF are both associated with social cognitive impairment, sleep particularly with the cognitive component. Identifying sleep problems in children with ADHD may provide helpful information in understanding and treating social cognitive impairments. This study is the first to draw attention to the relationship between sleep and social cognition. 相似文献

The social outcomes of pediatric traumatic brain injury (TBI) were examined in a prospective, longitudinal study that included 53 children with severe TBI, 56 with moderate TBI, and 80 with orthopedic injuries, recruited between 6 and 12 years of age. Child and family functioning were assessed at baseline, at 6- and 12-month follow-ups, and at an extended follow-up a mean of 4 years post injury. Growth curve analyses revealed that pediatric TBI yields negative social outcomes that are exacerbated by family environments characterized by lower socioeconomic status, fewer family resources, and poorer family functioning. After controlling for group membership, age, race, socioeconomic status, and IQ, path analyses indicated that long-term social outcomes were accounted for in part by specific neurocognitive skills, including executive functions and pragmatic language, and by social problem-solving. Deficits in these domains among children with TBI are likely to reflect damage to a network of brain regions that have been implicated in social cognition. 相似文献

Background: Up to now, little is known about higher order cognitive abilities like social cognition and social problem solving abilities in alcohol-dependent patients. However, impairments in these domains lead to an increased probability for relapse and are thus highly relevant in treatment contexts. Method: This cross-sectional study assessed distinct aspects of social cognition and social problem solving in 31 hospitalized patients with alcohol use disorder (AUD) and 30 matched healthy controls (HC). Three ecologically valid scenario-based tests were used to gauge the ability to infer the mental state of story characters in complicated interpersonal situations, the capacity to select the best problem solving strategy among other less optimal alternatives, and the ability to freely generate appropriate strategies to handle difficult interpersonal conflicts. Standardized tests were used to assess executive function, attention, trait empathy, and memory, and correlations were computed between measures of executive function, attention, trait empathy, and tests of social problem solving. Results: AUD patients generated significantly fewer socially sensitive and practically effective solutions for problematic interpersonal situations than the HC group. Furthermore, patients performed significantly worse when asked to select the best alternative among a list of presented alternatives for scenarios containing sarcastic remarks and had significantly more problems to interpret sarcastic remarks in difficult interpersonal situations.
Conclusions: These specific patterns of impairments should be considered in treatment programs addressing impaired social skills in individuals with AUD. 相似文献

Executive function mediated by prefrontally driven distributed networks is frequently impaired by traumatic brain injury (TBI) as a result of diffuse axonal injury and focal lesions. In addition to executive cognitive functions such as planning and working memory, the effects of TBI impact social cognition and motivation processes. To encourage application of cognitive neuroscience methods to studying recovery from TBI, associated reorganization of function, and development of interventions, this article reviews the pathophysiology of TBI, critiques currently employed methods of assessing executive function, and evaluates promising interventions that reflect advances in cognitive neuroscience. Brain imaging to identify neural mechanisms mediating executive dysfunction and response to interventions following TBI is also discussed. 相似文献

Childhood traumatic brain injury (TBI) is a common, acquired disability, which has significant implications for subsequent development, and for later quality of life. To date few studies have documented outcomes in these children into adolescence, when academic, social and personal demands increase. The objective of this study was to document functional outcomes at 10 years post-injury, and to identify predictors of outcome including injury, socio-demographic and pre-injury characteristics. The study employed consecutive recruitment to a prospective, longitudinal study. Children with a diagnosis of TBI between 2 and 12 years were initially recruited and divided according to injury severity (mild, moderate, severe). The sample was reviewed at 10 years post-injury and intellectual, adaptive, executive and social domains were investigated. Results indicated that, at 10 years post child TBI, survivors' functional abilities fell overall within the low average to average range regardless of injury severity, suggesting no extreme impairments at a group level for any of the domains under investigation. Significant group differences were identified, though, for adaptive abilities and for speed of processing, with more severe injury associated with poorer performances in each instance. Further, a similar trend was identified for measures of intellectual ability and executive functions. Individual rates of impairment were considerably higher than population expectations across all severity groups for these domains. Although rates of social impairment were also elevated, they were less related to injury factors, suggesting that cognitive/adaptive outcomes and social consequences of TBI may have different bases. 相似文献

ABSTRACTThis study examined the relationships between the Executive Function Performance Test (EFPT), the NIH Toolbox Cognitive Function tests, and neuropsychological executive function measures in 182 persons with traumatic brain injury (TBI) and 46 controls to evaluate construct, discriminant, and predictive validity. Construct validity: There were moderate correlations between the EFPT and the NIH Toolbox Crystallized (r?=??.479), Fluid Tests (r?=??.420), and Total Composite Scores (r?=??.496). Discriminant validity: Significant differences were found in the EFPT total and sequence scores across control, complicated mild/moderate, and severe TBI groups. We found differences in the organisation score between control and severe, and between mild and severe TBI groups. Both TBI groups had significantly lower scores in safety and judgement than controls. Compared to the controls, the severe TBI group demonstrated significantly lower performance on all instrumental activities of daily living (IADL) tasks. Compared to the mild TBI group, the controls performed better on the medication task, the severe TBI group performed worse in the cooking and telephone tasks. Predictive validity: The EFPT predicted the self-perception of independence measured by the TBI-QOL (beta = ?0.49, p?<?.001) for the severe TBI group. Overall, these data support the validity of the EFPT for use in individuals with TBI. 相似文献

The corpus callosum (CC) is vulnerable to severe traumatic brain injury (TBI). Social cognition requires integration of non-verbal and verbal information in order to understand social behaviour and may be compromised if the CC is damaged. 17 adults with severe, chronic TBI and 17 control participants underwent structural MRI and Diffusion Tensor Imaging. A region of interest analysis examined fractional anisotropy (FA) and mean diffusivity (MD) across regions of the CC. Performance on The Awareness of Social Inference Test (TASIT): part 1 (emotion recognition) and parts 2 and 3 (social inference), was examined in relation to FA and MD. Across participants, higher genu FA values were related to higher TASIT part 3 scores. Increased splenium FA was associated with better performance for TASIT parts 1–3. There was no association between DTI values and TASIT in the controls alone. In the TBI group, FA of the genu and splenium was correlated with TASIT part 3. The pattern of performance was similar when controlling for non-social cognitive ability. In conclusion, social information is complex and multi-modal requiring inter-hemispheric connection. People with TBI, regardless of focal grey matter injury, may lose social cognitive ability due to trauma related changes to the corpus callosum. 相似文献

Prospective memory (PM) is the ability to remember to perform a future action at a specified later time, which is investigated through the use of event-based and time-based tasks. Prior investigations have found that PM is impaired following traumatic brain injury (TBI). However, there is limited information regarding the cognitive functions that mediate TBI and PM performance. Thus, this study investigated time-based PM in TBI patients, and the relationship among time-based PM, time perception, and executive functions. To accomplish this objective, 18 severe TBI patients and 18 healthy matched controls performed a time-based PM task, a time reproduction task, and two executive functions (Stroop and n-back) tasks. While both groups increased their monitoring frequency close to the target time, TBI patients monitored more and were less accurate than healthy controls at the target time confirming the time-based PM dysfunction in these patients. Importantly, executive functions, particularly inhibition and updating abilities, were strongly related to time-based PM performance; both time perception and executive functions are involved in time-based prospective memory in controls, whereas, only executive functions appear to be involved in TBI time-based prospective memory performance. 相似文献

Social cognition is widely regarded as an essential skill with which to understand the social world. Despite this, the role that social cognition plays in outcome, and whether deficits are remediable after traumatic brain injury (TBI), are not yet well known. The current review examines the construct of social cognition and presents a conceptual biopsychosocial model with which to understand the social cognitive process. This is related to the literature on social cognitive deficits in TBI and we discuss relevant treatment developments to date within this population. We then review social cognition treatment programmes researched in other clinical populations in order to advise and inform approaches for those living with TBI. Whilst treatments have focused on emotion perception skills in the TBI literature, programmes developed for other clinical populations have had broader targets, focusing on Theory of Mind skills and/or modifying interpretational cognitive biases. Moreover, they have largely proven to be efficacious. Programmes that are contextualised, collaborative, and experiential seem optimal in enabling generalisation relevant to individuals’ everyday social lives. We argue that there is therefore scope to improve the evidence-based social cognitive treatment options available for those with TBI, taking into account specific adaptations necessary for this population. 相似文献

BackgroundMost developmental theories of autism spectrum disorders (ASD) emphasize a link between the ability to infer others' emotional states with their everyday social functioning. However, rarely has this association been empirically examined in this population.MethodsWe conducted a meta-analysis to quantitatively summarize correlations between performance on facial emotion recognition tasks and theoretically related variables broadly related to social functioning and other cognitive abilities.ResultsSixty-two correlation coefficients from 27 separate articles met our inclusion criteria. Correlations between the ability to recognize facial expressions (FER) and each category of variables were moderate but significant in the expected direction. FER was positively correlated with age, nonverbal and verbal intelligence, Theory of Mind, and adaptive functioning, and negatively correlated with alexithymia and higher ASD symptoms.ConclusionsThe findings of this meta-analysis indicate that FER abilities represent an important social cognitive ability given its relation to real-world social behavior and other characteristics and cognitive abilities. However, the striking lack of studies in this area calls for more research to gain a clearer understanding of the developmental significance of FER, especially in relation to the broader social impairment characteristic of ASD. 相似文献

ABSTRACTPost-traumatic hypopituitarism (PTH) associated with chronic cognitive, psychiatric, and/or behavioural sequelae is common following moderate to severe traumatic brain injury (TBI). More specifically, due to a cascade of hormonal deficiencies secondary to PTH, individuals with TBI may experience debilitating fatigue that can negatively impact functional recovery, as it can limit participation in brain injury rehabilitation services and lead to an increase in maladaptive lifestyle practices. While the mechanisms underlying fatigue and TBI are not entirely understood, the current review will address the specific anatomy and physiology of the pituitary gland, as well as the association between pituitary dysfunction and fatigue in individuals with TBI. 相似文献

Traumatic brain injury (TBI) often results in impairments in cognitive skills as well as depression. As a result of these changes in cognition and mood, individuals with TBI may reduce their levels of participation and often report reduced health-related quality of life (HrQOL). The current study compares levels of past and present activity participation between healthy participants and persons with TBI using a client-centred approach in measurement. We additionally examine the relationship between activity participation, emotional functioning and HrQOL in persons with TBI. Fifty-two individuals with TBI who live in the community and 30 healthy age-matched controls performed a battery of cognitive tests and rated their affective symptomatology and activity participation (using the Activity Card Sort Test). Participants with TBI reported significantly lower current activity participation compared to controls. Current levels of activity and participation in the TBI sample were significantly related to age, time since injury, and HrQOL. Additionally, depressive symptomatology was significantly associated with HrQOL, but not with activity participation. Following TBI, levels of activity participation are reduced in most aspects of life, but more profoundly in social activities, high demand leisure activities and household activities. Additionally, high levels of depressive symptoms are associated with negative reports of HrQOL, regardless of current levels of activity participation. 相似文献
