ObjectiveThe purpose of this study was to review the literature relating to the psychosocial costs associated with traumatic brain injury (TBI).MethodsNine online journal databases, including MEDLINE, CINAHL, PsychINFO, and PUBMED, were queried for studies between July 2010 and May 2012 pertaining to the economic burden of head injuries. Additional studies were identified through searching bibliographies of related publications and using Google internet search engine.ResultsOne hundred and eight potentially relevant abstracts were identified from the journal databases. Ten papers were chosen for discussion in this review. All but two of the chosen papers were US studies. The studies included a cost-benefit analysis of the implementation of treatment guidelines from the US brain trauma foundation and a cost-effectiveness analysis of post-acute traumatic brain injury rehabilitation.ConclusionVery little research has been published on the economic burden that mild and moderate traumatic brain injury patients pose to their families, careers, and society as a whole. Further research is needed to estimate the economic burden of these patients on healthcare providers and social services and how this can impact current health policies and practices.
Opinions about persisting post-concussional symptoms after minor traumatic brain injury still reflect a polarization of views around the sterile debate concerning the psychological vs organic origins of symptoms. Reviews of the experimental literature do not always integrate the often diverse perspectives that explain persisting symptoms of concussion. As a result, the disorder is still poorly understood. In this review, a diasthesis-stress paradigm examines the interaction between physiological and psychological factors that generate and maintain post-concussional symptoms. Motivational factors and different coping strategies are considered to explain why some people are at risk of developing a post-concussional syndrome. The early iatrogenic potential of GPs and hospital doctors who may create insecurity or reinforce illness perceptions is considered. Finally, the rationale and effectiveness of interventions that ameliorate the impact of early post-concussional symptoms is reviewed to see if prevention of the post-concussional syndrome is more effective than cure.
The frequency of alexithymia and the proportion of cases reporting low emotional empathy after traumatic brain injury (TBI) were compared with a control group. The study also examined the relationship between alexithymia and emotional empathy, controlling for the influence of cognitive ability, severity of head injury, and time since injury. A total of 64 TBI patients and matched controls completed the 20-Item Toronto Alexithymia Scale (TAS-20) and Balanced Emotional Empathy Scale (BEES). The TBI group exhibited a significantly higher frequency of alexithymia (60.9%) and low emotional empathy (64.4%) than did the control group (10.9% and 34.4%). Significant moderate negative correlations were found between TAS-20 and BEES scores, with TAS-20 total scores accounting for a significant amount of variance in BEES scores. However, no significant correlation was obtained between Subscale 1 of the TAS-20 (difficulty identifying feelings) and BEES scores in the TBI group. Additionally, there were no significant relationships between alexithymia, emotional empathy, injury severity, and time since injury. The results suggest an inverse relationship between alexithymia and emotional empathy.
Demographic factors and cognitive impairment have been found previously to have associations with outcome after brain injury. Kendall and Terry (1996) suggest that preinjury psychosocial functioning, neurological factors, and cognitive impairment have a direct relationship with multidimensional psychosocial adjustment, but that cognitive impairment also has an indirect relationship by means of the mediation of appraisal and coping variables. The aim of this study was to explore these theoretical relationships at very late stages of recovery after brain injury. A total of 131 participants who were more than 10 years after injury (mean 5 15.31 yr) completed a neuropsychological assessment, plus outcome measures that included employment status, community integration, life satisfaction, quality of life (QoL), and emotion. Results indicated that injury severity was predictive of life satisfaction; gender and relationship status predicted community integration; and age at injury predicted employment status. Impairment in working memory directly predicted all outcomes except QoL and anxiety. An indirect relationship was also evident between working memory, life satisfaction, and depression. Results partially support Kendall and Terry's model but the variables that significantly influence outcome seem to be determined by the outcome dimensions selected. (JINS, 2006, 12, 350-358.)
Deficits in emotional recognition and perception following traumatic brain injury (TBI) have been associated with alexithymia (Henry et al., 2006; Williams et al., 2001). This study examined the prevalence of alexithymia in a TBI population, and its relationship to injury severity, neuropsychological ability and affective disorder. A total of 121 patients completed the Toronto Alexithymia Scale-20 (TAS-20), a measure that addresses 3 distinct characteristics of the alexithymia concept; difficulty identifying feelings, difficulty describing feelings, and externally oriented thinking. Patients also completed a neuropsychological assessment and measures of depression and anxiety. Results confirm a high prevalence of alexithymia after TBI, relative to the general population and an orthopedic control group. There was no relationship between injury severity and the presence of alexithymia. A negative relationship was found between alexithymia and verbal and sequencing abilities, but there was no relationship with executive dysfunction or any other cognitive domain. Moderate correlations were obtained between alexithymia and affective disorder; regression analyses indicated that alexithymia, depression, and anxiety should be considered distinct, but overlapping constructs. The results of this study suggest that increased neuropsychological attention should be directed towards emotional change after head injury and its relationship with cognition and psychosocial outcome.
This study examines: (a) the impact of traumatic brain injury (TBI) on emotional empathy, (b) the relationship between emotional empathy and neuropsychological ability, and (c) the influence of low emotional empathy on measures of affect. Eighty-nine patients completed the Balanced Emotional Empathy Scale (BEES), a number of neuropsychological tests, some of which were ecologically valid tests of executive ability, plus two measures of affect, the Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI). The TBI cohort showed a high frequency (60.7%) of low emotional empathy scores compared to the control group (31%). There was no relationship between injury severity and the ability to empathize, or between emotional empathy and neuropsychological performance. There was no evidence to suggest that low scores on affective measures influenced emotional empathy scores. A high proportion of TBI patients lack the ability to empathize, but the deficit does not appear related to any specific cognitive impairment and cannot be predicted by measures of affect. (JINS, 2008, 14, 289-296.)
It is unclear how well performance on recently developed, specialized executive tests, reflects problems that patients and their relatives complain of in real life. The ecological validity of four specialised tests of executive function: the Hayling and Brixton Tests, and the Zoo Map and Key Search sub-tests from the Behavioural Assessment of Dysexecutive Syndrome (BADS) battery, was assessed against the Dysexecutive Questionnaire from the BADS in a sample of 59 severely brain injured individuals. Results indicated that only the Hayling C was significantly negatively correlated (r=-.26, P<.05) with the informant version of the Dysexecutive Questionnaire. An index of insight was not correlated with any of the executive tests. It is concluded that these tests have limited ecological validity when used to assess patients following severe head trauma.
Objectives: To examine very long term psychosocial outcome following severe brain injury in a large cohort, with the aim of evaluating Thomsen's observation that even after very serious head trauma the long term outcome in some patients is reasonably good. Methods: The cohort consisted of 80 patients who had suffered severe brain injury evaluated at a mean time of 17 years post injury (range 10-32 years). Information regarding employment status and relationship status was obtained during clinical interview. Psychosocial outcome measures included the Supervision Rating Scale, Satisfaction with Life Scale, Hospital Anxiety and Depression Scale (HADS), Patient Competency Rating Scale, and Community Integration Questionnaire. Results: Of the cohort, 72.0% lived independently, 28.7% were in full time employment, and 60.0% were married or cohabiting. The mean rating of life satisfaction was ''slightly dissatisfied'', but no serious emotional problems were evident from self report ratings on the HADS. Mean functional competency ratings and community integration levels were just below those reported for non-disabled patients. Conclusions: Results indicate that although long term psychosocial functioning in patients with severe head injury remains compromised, long term adjustment may be better than expected from data reported by studies assessing psychosocial outcome at earlier stages of recovery.
