ABSTRACTThe purpose of this study was to investigate the neurological correlates of both subjective fatigue as well as objective fatigability in individuals with traumatic brain injury (TBI). The study has a cross-sectional design. Participants ( N?=?53) with TBI (77% male, mean age at injury 38 years, mean time since injury 1.8 years) underwent a structural magnetic resonance imaging (MRI) scan and completed the Fatigue Severity Scale (FSS), while a subsample ( N?=?36) was also tested with a vigilance task. While subjective fatigue (FSS) was not related to measures of brain lesions, multilevel analyses showed that a change in the participants’ decision time was significantly predicted by grey matter (GM) lesions in the right frontal lobe. The time-dependent development of the participants’ error rate was predicted by total brain white matter (WM) lesion volumes, as well as right temporal GM and WM lesion volumes. These findings could be explained by decreased functional connectivity of attentional networks, which results in accelerated exhaustion during cognitive task performance. The disparate nature of objectively measurable fatigability on the one hand and the subjective experience of fatigue on the other needs further investigation. 相似文献

ObjectivesTo compare individuals with traumatic brain injury (TBI) to healthy controls (CTLs) on measures of sleepiness, fatigue, and sleep, and explore correlates of sleepiness and fatigue separately for each group. MethodsParticipants were 22 adults with moderate/severe TBI (time since injury ?1 year; mean = 53.0 ± 37.1 months) and 22 matched healthy CTLs. They underwent one night of polysomnographic (PSG) recording of their sleep followed the next day by the Maintenance of Wakefulness Test (MWT). They also completed a 14-day sleep diary, the Epworth Sleepiness Scale (ESS), the Functional Outcomes of Sleep Questionnaire (FOSQ), and the Multidimensional Fatigue Inventory (MFI). ResultsThere were no significant group differences on measures of objective (MWT) or subjective (ESS) sleepiness, both groups being quite alert. However, TBI participants reported greater consequences of sleepiness on their general productivity (FOSQ), spent more time in bed at night, and napped more frequently and for a longer time during the day. Subjective fatigue was significantly higher in TBI participants on the general, physical, and mental fatigue MFI subscales. There were no between-group differences on any sleep parameters derived either from PSG or sleep diary. ConclusionsFatigue appeared to be a more prominent symptom than sleepiness when assessed between 1 and 11 years after TBI. Participants with TBI used compensatory strategies such as increasing time spent in bed and daytime napping in this sample. Future research should document the time course of sleepiness and fatigue after TBI and investigate treatment options. 相似文献

ABSTRACTFatigue is one of the most commonly reported sequelae after traumatic brain injury (TBI). This study evaluated the impact of a graduated physical activity programme on fatigue after TBI. Using a prospective randomised single-blind crossover design, 123 individuals with TBI, over the age of 18, were enrolled. Interventions included a home-based walking programme utilising a pedometer to track daily number of steps at increasing increments accompanied by tapered coaching calls over a 12-week period. Nutritional counselling with the same schedule of coaching calls served as the control condition. Main outcome measures included: the Global Fatigue Index (GFI), the Barrow Neurological Institute (BNI) Fatigue Scale Overall Severity Index Score, and the Multidimensional Fatigue Inventory (MFI). Step counts improved over time regardless of group assignment. The walking intervention led to a decrease in GFI, BNI Total, and MFI General scores. Participants reported less fatigue at the end of the active part of the intervention (24 weeks) and after a wash out period (36 weeks) as measured by the BNI Overall. The study suggests that walking can be used as an efficient and cost-effective tool to improve fatigue in persons who have sustained a TBI. 相似文献

ABSTRACTPost-traumatic fatigue (PTF) is a common, disabling, and often chronic symptom following traumatic brain injury (TBI). Yet, the impact of chronic cognitive and physical fatigue and their associations with psychiatric, sleep, cognitive, and psychosocial sequelae in mild–moderate TBI remain poorly understood. Sixty Veterans with a history of mild–moderate TBI and 40 Veteran controls (VC) were administered the Modified Fatigue Impact Scale, a validated measure of TBI-related cognitive and physical fatigue as well as measures of neuropsychiatric, psychosocial, sleep, and objective cognitive functioning. Compared to VC, TBI Veterans endorsed significantly greater levels of cognitive and physical fatigue. In TBI, psychiatric symptoms, sleep disturbance, and post-traumatic amnesia (PTA) were associated with both cognitive and physical fatigue, while loss of consciousness (LOC) and poor attention/processing speed were related to elevations in cognitive fatigue only. In regression analyses, anxiety, sleep disturbance, and LOC significantly predicted cognitive fatigue, while only post-traumatic stress symptoms and PTA contributed to physical fatigue. Cognitive and physical fatigue are problematic symptoms following mild–moderate TBI that are differentially associated with specific injury and psychiatric sequelae. Findings provide potential symptom targets for interventions aimed at ameliorating fatigue, and further underscore the importance of assessing and treating fatigue as a multi-dimensional symptom following TBI. 相似文献

ObjectivesThe primary aim was to examine whether sleep disturbances persist in children in the chronic stage of recovery from moderate or severe traumatic brain injury (TBI). The secondary aim was to examine whether memory difficulties and/or other previously identified factors relate to sleep disturbances in children with moderate to severe TBI. MethodsThis longitudinal study included 21 children with moderate to severe TBI, 8–18 years old, recruited from an urban tertiary paediatric specialised brain injury rehabilitation unit. Participants were seen 5 years and again 7 years post-injury, on average. Sleep disturbances were assessed with Sleep Disturbance Scale for Children (SDSC). Correlates that were considered included indicators of TBI severity, and questionnaires assessing everyday memory, fatigue, internalizing and externalizing behaviors and pain intensity. ResultsThe SDSC scores of children with moderate to severe TBI indicated greater disturbances in initiating and maintaining sleep, arousal, sleep-wake transition, and excessive somnolence relative to the norms, at follow-up. The mean SDSC scores and the number of participants with subclinical to clinical sleep disturbances on the SDSC remained unchanged from baseline to follow-up. At follow-up, the SDSC initiating and maintaining sleep, and excessive somnolence scales were associated with poorer everyday memory and greater fatigue. ConclusionsChildren with moderate to severe TBI experience ongoing sleep disturbances for years post-injury. Greater sleep disturbances are associated with worse functional outcomes. Further research into sleep disturbances and development of treatments is important, as it could improve the outcomes of children with TBI. 相似文献

ABSTRACTThe objectives of this study were to document the evolution of fatigue in the first year after traumatic brain injury (TBI), and to explore correlates of fatigue. Participants were 210 adults who were hospitalised following a TBI. They completed questionnaires 4, 8, and 12 months post-injury, including the Multidimensional Fatigue Inventory (MFI). Participants with severe TBI presented greater mental and physical fatigue, and reduced activity compared to participants with moderate TBI. For all MFI subscales except reduced motivation, the general pattern was a reduction of fatigue levels over time after mild TBI, an increase of fatigue after severe TBI, and stable fatigue after moderate TBI. Fatigue was significantly associated with depression, insomnia, cognitive difficulties, and pain at 4 months; the same variables and work status at 8 months; and depression, insomnia, cognitive difficulties, and work status at 12 months. These findings suggest that injury severity could have an impact on the course of fatigue in the first year post-TBI. Depression, insomnia, and cognitive difficulties remain strong correlates of fatigue, while for pain and work status the association with fatigue evolves over time. This could influence the development of intervention strategies for fatigue, implemented at specific times for each severity subgroup. 相似文献

ObjectiveWe aimed to investigate the presence of brachial plexus injury (BPI) in traumatic brain injury (TBI) patients and to draw attention to BPI, which can be overlooked by physicians in TBI patients. MethodsThe study was designed retrospectively by examining the files of 58 patients with moderate to severe TBI to investigate coexistence of TBI and BPI. ResultsBPI was detected in six of 58 TBI patients (10.3%). BPI was detected after an average 116 days from the initial injury. Three patients had lower trunk BPI and three patients had panplexopathy. ConclusionDiagnosis of BPI in patients with TBI is delayed in the acute period of injury. The clinicians should keep in mind that BPIs may occur and remain undiagnosed in patients with TBI. 相似文献

Abstract This study was undertaken to better understand the subjective experience of long-term cognitive-communicative impairments following severe cerebral insult. An additional aim was to explore the utility of a model of interpersonal communication in elucidating how such difficulties affect communicative interactions. Participants in the study were five dyads in which one member had sustained a severe traumatic brain injury (TBI). Data collection and analysis utilized both qualitative and quantitative methodology. It was found that individuals with long-term TBI continue to experience significant communication difficulties, which in combination with problems of memory, fatigue and irritability commonly generate unsatisfactory interpersonal communication experiences. The model of interpersonal communication provided a useful framework for considering why these interactions are ineffective or unsatisfactory. It is felt that the methodology outlined in this paper may offer a useful means of investigating the relationship between neurogenic communication impairments/disabilities and interpersonal communication difficulties experienced by individuals from a variety of clinical populations. 相似文献

BackgroundIn severe traumatic brain injury (TBI) patients undergoing decompressive hemicraniectomy (DHC), the rate of post-traumatic hydrocephalus (PTH) is high at 12–36%. Early diagnosis and shunt placement can improve outcomes. Herein, we examined the incidence of and predictors of PTH after craniectomy. MethodsA retrospective analysis of prospectively collected database of severe TBI patients at a single U.S. Level 1 trauma center from May 2000 to July 2014 was performed. Demographics, Injury Severity Score (ISS), Glasgow Coma Scale (GCS), bleeding pattern and time-to-cranioplasty were analyzed. Glasgow Outcome Scale (GOS) scores at 6 and 12-months were studied. Statistical significance was assessed at p < 0.05. ResultsA total of 402 patients were enrolled and 105 patients had DHC. Twenty-two (21.0%) of 105 required ventriculoperitoneal shunt (VPS), compared to 18 (6%) of 297 patients without DHC. There was increased odds ratio for shunting after DHC at 3.62 (95%CI:1.62–8.07; p < 0.01). Mean age at time of DHC was 43.8 ± 17.7 years old, and 81.9% were male. Subdural hematoma (SDH) was most common at 57.1%. Median time from admission to cranioplasty was 63 days. Patients who experienced PTH after DHC were younger (35.5 ± 17.7 versus 46.0 ± 17.7 years, p < 0.01) and had higher ISS scores (35 versus 26, p = 0.04) compared to patients without shunt after DHC. ConclusionsAfter severe TBI requiring hemicraniectomy, shunt-dependent hydrocephalus was 21%. Younger patients and higher ISS score were associated with PTH. Shunt-dependent patients achieved similar 6- and 12-month outcomes as those without PTH. Early diagnosis and shunt placement can enhance long-term neurological recovery. 相似文献

AbstractTraumatic brain injury (TBI) is one of the leading causes of death and disability world wide. In the United States alone, nearly 1·7 million individuals are treated in the hospital setting for TBI of all severities, which accounts for over US$48 billion of health care cost annually. This special issue of Neurological Research provides a broad coverage of several important topics in TBI, including contemporary imaging of mild TBI, management of chronic subdural hematoma (cSDH), use of vagus nerve stimulation (VNS) to treat TBI, reviews on blast TBI and chronic traumatic encephalopathy (CTE), as well as basic science studies in different rodent models of TBI. The authors aim to provide some insight on TBI to neurosurgeons, neurologists, rehabilitation doctors, and other specialists treating TBI patients as well as neuroscientists who are involved in neurotrauma research. 相似文献

ABSTRACTPurpose: Examine the impact of traumatic brain injury (TBI) on parenting behavior over time. Method: Included 206 children (3–7 years old) with moderate to severe TBI or orthopedic injury, using a prospective longitudinal cohort study design. Assessments completed at baseline, 6-months, 12-months, 18-months, 3.5 years, and 6.8 years after injury. Dependent variables included authoritative, permissive, and authoritarian parenting. Results: Injury characteristics had limited impact on parenting behaviors over time. Levels of authoritative parenting remained stable over time; however, levels of warmth and involvement declined over time for those with TBI. Levels of permissive and authoritarian parenting declined for all participants by 3.5 years post injury. SES and stressors impacted parenting behaviors. Conclusions: While there was limited effect of TBI on parenting behavior over time, it remains unclear how individuals respond to these parenting behaviors years after injury. Clinicians should monitor family and parenting behaviors to foster an environment to promote positive recovery. 相似文献

Objectives: An association has been postulated between traumatic brain injury (TBI) and depression. The serotonin transporter (SERT) regulates the concentration of serotonin in the synaptic cleft and represents a molecular target for antidepressants. We hypothesized that SERT expression in the brain changes following TBI. Methods: We performed immunohistochemistry, real-time polymerase chain reaction analysis for mRNA and western blot analysis for protein to examine the time-dependent changes in SERT expression in the cerebrum during the first 14 days after TBI, using a controlled cortical impact model in rats. Results: SERT immunoreactivity in neuronal fibres within the area adjacent to the cortical contusion decreased 1 to 14 days after injury. Significantly decreased SERT mRNA and protein expression were noted in the area adjacent to the cortical contusion 7 days after injury. There were no significant changes in SERT expression in the cingulum of the injured brain. Discussion: The findings of this study indicate that TBI decreases SERT expression in the cerebral cortex. The decreased levels of SERT expression after TBI may result in decreased serotonin neurotransmission in the brain and indicate a possible relationship with depression following TBI. 相似文献

BackgroundWhile traumatic brain injury (TBI) can lead to epilepsy, individuals with preexisting epilepsy or seizure disorder (ESD), depending on the type of epilepsy and the degree of seizure control, may have a greater risk of TBI from seizure activity or medication side effects. The joint occurrence of ESD and TBI can complicate recovery as signs and symptoms of TBI may be mistaken for postictal effects. Those with ESD are predicted to experience more deleterious outcomes either because of having a more severe TBI or because of the cumulative effects of repetitive TBI. MethodsWe conducted a case–control study of all emergency department visits and hospital discharges for TBI from 1998 through 2011 in a statewide population. The severity of TBI, repetitive TBI, and other demographic and clinical characteristics were compared between persons with TBI with preexisting ESD (cases) and those without (controls). Significant differences in proportions were evaluated with confidence intervals. Logistic regression was used to examine the association of the independent variables with ESD. ResultsDuring the study period, 236,164 individuals sustained TBI, 5646 (2.4%) of which had preexisting ESD. After adjustment for demographic and clinical characteristics, cases were more likely to have sustained a severe TBI (OR = 1.49; 95% CI = 1.38–1.60) and have had repetitive TBI (OR = 1.54; 95% CI = 1.41–1.69). ConclusionThe consequences of TBI may be greater in individuals with ESD owing to the potential for a more severe or repetitive TBI. Seizure control is paramount, and aggressive management of comorbid conditions among persons with ESD and increased awareness of the hazard of repetitive TBI is warranted. Furthermore, future studies are needed to examine the long-term outcomes of cases in comparison with controls to determine if the higher risk of severe or repetitive TBI translates into permanent deficits. 相似文献

Background and aims: Behaviours of Concern (BoC) are a debilitating consequence of Traumatic Brain Injury (TBI). Whilst perspectives of clinicians, carers and family members on BoC have been previously explored, few qualitative studies have included individuals with TBI. The aim of this study was to explore the lived experience of BoC in individuals with TBI, their close others and clinicians. Method: Eleven males with TBI and BoC were recruited and 25 semi-structured qualitative interviews were conducted (9 individuals with TBI, 9 close others, 7 clinicians). A six-phase thematic analysis approach was utilised. Results: Frequent and persistent BoC were reported and the key themes identified included the brain injury, control, environment, mood, identity, social relationships, and meaningful participation. Whilst the brain injury contributed to BoC in all cases, the way the other themes manifested and interacted was variable. Conclusions: This study enriches our understanding of factors associated with BoC. Themes emerging from this study will inform interventions designed to reduce BoC and ultimately maximise quality of life for individuals with TBI and their families. 相似文献

ABSTRACTMental fatigue is a frequently occurring symptom after mild, moderate or severe traumatic brain injury (TBI). Such mental fatigue may become a long-lasting problem, irrespective of severity and even after recovery from other neurological or psychiatric symptoms. Two characteristics of this mental fatigue are that patients easily become exhausted and there is generally a long recovery time. There is a need to increase knowledge and awareness of mental fatigue as it interferes considerably with work, studies, and social activities. Assessment is difficult and few treatment studies have been carried out. For the purposes of assessment, the development of the Mental Fatigue Scale is described here, and we also summarise the few treatment studies found for fatigue after TBI. Symptom alleviation is reported through Mindfulness-Based Stress Reduction (MBSR), light therapy and for the psychostimulant methylphenidate and the dopamine stabiliser (-)-OSU6162. However, more knowledge of the origin of mental fatigue and its underlying mechanisms is needed for development of more efficient therapeutic methods. Prospective randomised trials focusing on long-term outcomes are warranted and should include both pharmacological and non-pharmacological treatments. 相似文献

Impairment of prospective memory (PM) is a common problem following traumatic brain injury (TBI) which can affect functional outcomes. PM failures in everyday life can be assessed using self-report questionnaires; however, existing measures tend to be lengthy, which may be problematic for individuals with fatigue and other cognitive impairments. This study aimed to develop a short form of the Comprehensive Assessment of Prospective Memory (CAPM) and examine its psychometric properties. Using theoretical and statistical considerations, the number of items on the CAPM was reduced to 16 including equal numbers representing the basic activities of daily living (BADL) and instrumental activities of daily living (IADL) subscales. The psychometric properties of the new measure, named the Brief Assessment of Prospective Memory (BAPM), were examined by secondary analysis of data from two samples of community dwelling adults (aged 17 to 91 years, n = 527, and 15 to 60 years, n?=?95) with no history of brain injury, and a sample of rehabilitation patients with moderate to severe TBI ( n?=?45). Results indicate that the BAPM has a robust factor structure, strong agreement with the original CAPM, acceptable internal consistency and test-retest reliability, and evidence of criterion-related validity with psychosocial integration as the point of reference for people with TBI. 相似文献

ObjectivesTrigeminal nerve stimulation (TNS) is a promising strategy in treating diseases of the nervous system. In this study, the effects of TNS on traumatic brain injury (TBI) were investigated in a mouse model. Materials and MethodsTBI was induced using a weight-drop device, and TNS treatment was delivered in the first hour after the TBI. Twenty-four hours later, the mice’s behavior, brain edema, and expression of inflammatory factors were tested. Functional magnetic resonance imaging also was used to explore the possible effects of TNS on brain activity. ResultsTNS alleviates TBI-induced neurological dysfunction in animal behavior tests, besides protecting the blood-brain barrier and reducing the level of brain edema. TNS also effectively reduces the level of tumor necrosis factor-α and interleukin 6 and downregulates the cleaved caspase-3 signaling pathway. A series of brain areas was found to be possibly regulated by TNS, thus affecting the neural functions of animals. ConclusionThis study elucidates the role of TNS as an effective treatment for TBI by inhibiting the occurrence of a secondary brain injury. 相似文献
