ABSTRACT

OBJECTIVE: The investigators examined predictors of treatment response to anger self-management training (ASMT) among patients with chronic moderate-severe traumatic brain injury (TBI). METHODS: A multicenter randomized clinical trial comprising 90 participants with moderate-severe TBI was conducted. Fifty-four participants who were randomly assigned to receive active treatment and provided complete data were included in the current secondary analysis. Model averaging was used to examine the relative importance and significance of pretreatment variables for predicting change during treatment. Dependent variables were pre- to posttreatment changes in trait anger (TA) and anger expression-out (AX-O) subscale scores of the State-Trait Anger Expression Inventory-Revised. Predictors included demographic, injury-related, and neuropsychological variables, including both objective and self-reported measures of executive function, as well as readiness to change and participation of a significant other in treatment. RESULTS: Change in both dependent variables was predicted by higher baseline anger. Greater change in TA was additionally predicted by White race, higher education, shorter posttraumatic amnesia, and worse self-reported (but not objectively measured) executive dysfunction; the latter predictor may have indicated better self-awareness. Greater change in AX-O was additionally predicted by better episodic memory and, paradoxically, lower readiness to change. CONCLUSIONS: Further research should focus on adapting psychoeducational anger treatments to better serve the diverse populations affected by moderate-severe TBI. These findings suggest that providing memory aids to support the use of learned strategies after treatment cessation would be beneficial. Further research should also examine the construct of readiness to change and specific aspects of executive function that may affect treatment response in psychoeducational treatments. These findings were derived from only one model of anger intervention, and the relevance to other treatment approaches cannot be assumed.

ABSTRACT

Objective: To examine patterns of change in social participation in persons with moderate-severe traumatic brain injury (msTBI) between 1 and 2 years postinjury, and predictors of observed change. Participants: 375 participants with msTBI enrolled in a single TBI Model System site. Measures and Methods: The dependent variable in a linear regression was a reliable change score for the Social Relations subscale of the Participation Assessment with Recombined Tools-Objective, administered at 1- and 2-year follow-ups. Predictors of change included demographics, injury severity, social and functional status at Year 1, and changes in function and life circumstances between years 1 and 2. Results: Social participation status did not change substantially for 3 4 of the sample, while approximately equal proportions of the remainder improved or declined. The regression model was significant (p < 0.001). Improvement was predicted by private vs. public insurance and decline was predicted by a reduction in the FIM functional outcome measure from year 1 to year 2. Marginal predictors included education (higher levels predicting improvement) and year 1 marital status (single status predicting decline). Conclusions: Longitudinal change in social participation in the chronic phase of msTBI deserves further study, with attention to resource limitations and the impact of changes in functional status.

ABSTRACT

Psychiatric sequelae of traumatic brain injury (TBI) can cause significant and often chronic impairment in functioning and quality of life; however, their phenomenological and mechanistic complexities continue to present significant treatment challenges. The clinical presentation is often an amalgam of syndromes and co-occurring symptoms that require a highly nuanced and systematic approach to treatment. Although few randomized controlled trials have tested treatments for psychiatric problems after TBI and the synthesis of results continues to be compromised by the heterogeneity of study populations, small samples, and differing inclusion criteria and outcome measures, an increasing body of literature supports evidence-based treatment strategies. We provide a narrative review of pharmacological, psychoeducational/behavioral, and neuromodulation treatments for psychiatric conditions in adults with TBI and discuss known or postulated mechanisms of action for these treatment approaches. Where data are available, we focus on randomized controlled trials and large case series in which a psychiatric condition provides both a selection criterion and a primary or secondary outcome. We conclude by proposing directions for future research, particularly the need for novel neuropharmacological, behavioral, and neurophysiological studies and pragmatic trials of multicomponent and adaptive models that will increase understanding of the mechanisms underlying post-TBI psychiatric disorders and accelerate dissemination and implementation of effective person-centered care.

ABSTRACT

PURPOSE: To describe where, with whom, and how time was spent daily, and to characterize positive and negative affect, boredom, enjoyment, and perceived accomplishment as a function of time, activity, location, and social context, in people with chronic moderate-severe traumatic brain injury and depression/anxiety. RESEARCH METHOD: Participants (N = 23) responded to a smartphone app five times daily for approximately 2 weeks prior to treatment in a trial of Behavioral Activation. The app queried activity and physical/social context; concurrent positive and negative affect; and perceived boredom, enjoyment, and accomplishment. Descriptive statistics captured time use, and linear mixed models were used to analyze relations between affect and contextual factors. RESULTS: Ecological Momentary Assessment (EMA) response rate was positively correlated with integrity of episodic memory and education. Participants spent most time at home versus elsewhere, and alone versus with others. The most frequent activity was watching TV. Mixed model results based on 17 participants with >33% response rate showed that positive affect was associated with being outside of home, and with other people; however, socializing was related to higher negative affect. TV watching was related to lower negative affect but also low accomplishment. CONCLUSIONS: EMA can provide unique information on the effects of social context and activity on mood in TBI. Clinicians should consider negative as well as positive affect associated with increasing social participation. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

ABSTRACT

OBJECTIVE: To identify psychosocial and functional predictors of self-reported depression and anxiety symptoms at year 2 following traumatic brain injury (TBI). SETTING: Five Department of Veterans Affairs (VA) Polytrauma Rehabilitation Centers (PRCs) within the TBI Model Systems (TBIMS). PARTICIPANTS: A total of 319 service members/veterans enrolled in VA TBIMS who were eligible for and completed both 1- and 2-year follow-up evaluations. DESIGN: Secondary analysis from multicenter prospective longitudinal study. MAIN MEASURES: Demographic, injury-related, military, mental health, and substance use variables. Questionnaires included the Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), and Neurobehavioral Symptom Inventory. Rating scales included the Participation Assessment with Recombined Tools-Objective and Disability Rating Scale. RESULTS: The final sample was largely male (96%) and predominantly White (65%), with a median age of 27 years. In unadjusted analyses, pre-TBI mental health treatment history and year 1 employment status, community activity, sleep difficulties, and self-reported depression and anxiety symptoms were associated with year 2 PHQ-9 scores; pre-TBI mental health treatment history and year 1 community activity, social contact, problematic substance use, sleep difficulties, and self-reported depression and anxiety symptoms were associated with year 2 GAD-7 scores. In multivariable analyses, only year 1 community activity and depression symptoms uniquely predicted year 2 PHQ-9 scores, and only year 1 employment status, community activity, problematic substance use, and anxiety symptoms uniquely predicted year 2 GAD-7 scores. CONCLUSION: Anxiety and depression commonly occur after TBI and are important treatment targets. Some predictors (eg, participation and substance use) are modifiable and amenable to treatment as well. Early identification of anxiety and depression symptoms is key.

ABSTRACT

This study aims to characterize the patterns of functional change experienced between 5 and 10 years after moderate-severe traumatic brain injury (TBI). The study included TBI Model Systems national database participants (N = 372) at six sites who experienced TBI, received inpatient rehabilitation, and were followed at 5 and 10 years post-TBI. Outcome measures included self- or proxy-reported Functional Independence Measure (FIMTM) structured interview at 5 and 10 years post-TBI and domain change indices (DCIs) at 10 years to assess subjective change over the previous 5 years. When all seven FIM and subjective DCI subscales were considered together, 69% reported improvement in at least one subscale and 41% reported decline in at least one subscale; 51% reported more domains improved than declined, and 20% reported more domains declined than improved. Age at injury, post-traumatic amnesia duration, FIM, and depression and anxiety at year 5 were associated with FIM change and DCI measures. Although most persons with moderate-severe TBI do not experience widespread change from year 5 to 10 on individual FIM subscales or perceived domain-specific subscales, the vast majority do report change in one or more domains, with more improvement than decline and more change in subjective DCI than in FIM. Clinicians and researchers should be alert to the possibility of both positive and deleterious changes many years after TBI.

ABSTRACT

Moderate to severe traumatic brain injury (TBI) is a common cause of long-term disability. Due to challenges that include inconsistent access to follow-up care, persons with TBI being discharged from inpatient rehabilitation facilities (IRFs) are at risk for rehospitalization, poor reintegration into the community, family stress, and other unfavorable outcomes resulting from unmet needs. In a six-center randomized pragmatic comparative effectiveness study, the BRITE trial (Brain Injury Rehabilitation: Improving the Transition Experience, ClinicalTrials.govNCT03422276), we compare the effectiveness of two existing methods for transition from IRF to community living or long-term nursing care. The Rehabilitation Discharge Plan (RDP) includes patient/family education and referrals for continued care. The Rehabilitation Transition Plan (RTP) provides RDP plus individualized, manualized care management via phone or videoconference, for 6 months. Nine hundred patients will be randomized (1:1) to RDP or RTP, with caregivers also invited to participate and contribute caregiver-reported outcomes. Extensive stakeholder input, including active participation of persons with TBI and their families, has informed all aspects of trial design and implementation planning. We hypothesize that RTP will result in better patient- and caregiver-reported outcomes (societal participation, quality of life, caregiver well-being) and more efficient use of healthcare resources at 6-months (primary outcome) and 12-months post-discharge, compared to RDP alone. Planned analyses will explore which participants benefit most from each transition model. With few exclusion criteria and other pragmatic features, the findings of this trial are expected to have a broad impact on improving transitions from inpatient TBI rehabilitation. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT03422276.

ABSTRACT

OBJECTIVE: To develop a measure of global functioning after moderate-severe TBI with similar measurement precision but a longer measurement range than the FIM. DESIGN: Phase 1: retrospective analysis of 5 data sets containing FIM, Disability Rating Scale, and other assessment items to identify candidate items for extending the measurement range of the FIM; Phase 2: prospective administration of 49 candidate items from phase 1, with Rasch analysis to identify a unidimensional scale with an extended range. SETTING: Six TBI Model System rehabilitation hospitals. PARTICIPANTS: Individuals (N=184) with moderate-severe injury recruited during inpatient rehabilitation or at 1-year telephone follow-up. INTERVENTIONS: Participants were administered the 49 assessment items in person or via telephone. MAIN OUTCOME MEASURES: Item response theory parameters: item monotonicity, infit/outfit statistics, and Factor 1 variance. RESULTS: After collapsing misordered rating categories and removing misfitting items, we derived the Brain Injury Functional Outcome Measure (BI-FOM), a 31-item assessment instrument with high reliability, greatly extended measurement range, and improved unidimensionality compared with the FIM. CONCLUSIONS: The BI-FOM improves global measurement of function after moderate-severe brain injury. Its high precision, relative lack of floor and ceiling effects, and feasibility for telephone follow-up, if replicated in an independent sample, are substantial advantages.

ABSTRACT

OBJECTIVE: To assess the impact of staff training focused on improved treatment and communication with patients in post-traumatic amnesia (PTA) or other disorders of explicit (declarative) memory. A major aim was to minimize questions demanding recall from explicit memory, e.g., orientation quizzing, and personal/medical history questions, which may produce unreliable information and exacerbate patient frustration and anxiety. METHODS: Mixed-methods design. Inpatients with impairments of explicit memory were observed before (n = 4) and after (n = 4) training, with staff interactions recorded verbatim. Records were coded for types of questions and patient responses. Clinicians who worked before and after training were surveyed regarding perceived changes in practice, team functioning, and patient behavior. RESULTS: Explicit memory questions decreased significantly, as did irrelevant or "don't know" responses from patients, with large nonparametric effect sizes noted. The frequency of questions not relying on explicit memory remained stable. Most clinicians reported positive effects on their own and others' practice with memory impaired patients, and one-quarter noted less patient frustration or agitation. CONCLUSIONS: Although questioning patients is a natural part of medical care, targeted staff training can result in positive changes in communication practice and should be considered for facilities treating patients in PTA.

ABSTRACT

OBJECTIVE: To examine heterogeneity in the temporal patterns of depression and participation over the first 2 years post traumatic brain injury (TBI). DESIGN: Observational prospective longitudinal study. SETTING: Inpatient rehabilitation centers, with 1- and 2-year follow-up conducted primarily by telephone. PARTICIPANTS: Persons with TBI (N=2307) enrolled in the Traumatic Brain Injury Model Systems database, followed at 1 and 2 years post injury. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Patient Health Questionnaire-9 (PHQ-9) and Participation Assessment With Recombined Tools-Objective (PART-O). RESULTS: Using latent class modeling we examined heterogeneity in the longitudinal relationship between PHQ-9 and PART-O. The identified 6 classes were most distinct in terms of (1) level of PHQ-9 score and (2) association between the year 1 PART-O score and year 2 PHQ-9 score. For most participants, PART-O at year 1 predicted PHQ-9 at year 2 more than the reverse. However, there was a subgroup of participants that demonstrated the reverse pattern, PHQ-9 predicting later PART-O, who were on average, older and in the "other" employment category. CONCLUSIONS: Results suggest that links between participation and depression are stronger for some people living with TBI than for others and that variation in the temporal sequencing of these 2 constructs is associated with demographic characteristics. These findings illustrate the value in accounting for population heterogeneity when evaluating temporal among outcome domains.

ABSTRACT

OBJECTIVE: To examine the association between social Internet use and real-world societal participation in survivors of moderate-severe traumatic brain injury. DESIGN: Prospective cross-sectional observational study. SETTING: Ten Traumatic Brain Injury Model Systems Centers. PARTICIPANTS: A total of 331 participants in the Traumatic Brain Injury Model Systems, interviewed at any follow-up year between April 2014 and March 2015. MAIN MEASURES: Survey on Internet use, including social media and other online socialization; Participation Assessment with Recombined Tools-Objective with separate analyses of Productivity, Social Relations, Out and About subscales; covariates included demographics, injury variables, and functional and emotional status at follow-up. RESULTS: Participants were classified as social Internet users (N = 232) or nonusers (N = 99). Users had significantly higher Participation Assessment with Recombined Tools-Objective Social Relations scores than nonusers. A similar finding pertained to Out and About scores, with the between-group difference significantly greater for those with greater depressive symptoms severity. Users and nonusers did not differ significantly on Productivity subscale. CONCLUSIONS: The positive association between social Internet use and real-world social participation suggests that people with traumatic brain injury do not use social media as an alternative to real-world socialization. Rather, it is likely that similar barriers and facilitators affect both online and real-world social participation following traumatic brain injury. Emotional function should be considered as a moderating factor in further studies.

ABSTRACT

OBJECTIVES: Treatment enactment, a final stage of treatment implementation, refers to patients' application of skills and concepts from treatment sessions into everyday life situations. We examined treatment enactment in a two-arm, multicenter trial comparing two psychoeducational treatments for persons with chronic moderate to severe traumatic brain injury and problematic anger. METHODS: Seventy-one of 90 participants from the parent trial underwent a telephone enactment interview at least 2 months (median 97 days, range 64-586 days) after cessation of treatment. Enactment, quantified as average frequency of use across seven core treatment components, was compared across treatment arms: anger self-management training (ASMT) and personal readjustment and education (PRE), a structurally equivalent control. Components were also rated for helpfulness when used. Predictors of, and barriers to, enactment were explored. RESULTS: More than 80% of participants reported remembering all seven treatment components when queried using a recognition format. Enactment was equivalent across treatments. Most used/most helpful components concerned normalizing anger and general anger management strategies (ASMT), and normalizing traumatic brain injury-related changes while providing hope for improvement (PRE). Higher baseline executive function and IQ were predictive of better enactment, as well as better episodic memory (trend). Poor memory was cited by many participants as a barrier to enactment, as was the reaction of other people to attempted use of strategies. CONCLUSIONS: Treatment enactment is a neglected component of implementation in neuropsychological clinical trials, but is important both to measure and to help participants achieve sustained carryover of core treatment ingredients and learned material to everyday life.

ABSTRACT

OBJECTIVE: To characterize the influence of additional (both prior and subsequent) traumatic brain injuries (TBIs) on recovery after a moderate to severe index TBI. SETTING: Traumatic Brain Injury Model Systems centers. PARTICIPANTS: Persons with moderate to severe TBI (N = 5054) enrolled in the TBI Model Systems National Database with complete outcome data for the outcomes of interest at 1-, 2-, and 5-year follow-up. DESIGN: Secondary analysis of a prospective longitudinal data set. MAIN MEASURES: Prior and intercurrent TBI from the Ohio State University TBI Identification Method (OSU TBI-ID), Disability Rating Scale (DRS), and Functional Independence Measure (FIM). RESULTS: Prior moderate-severe TBIs significantly predicted overall level of functioning on the DRS, FIM Cognitive, and FIM Motor for participants with less severe index injuries. Moderate-severe intercurrent TBIs (TBIs subsequent to the index injury) were predictive of poorer functioning for both Index Severity groups, reflected in higher mean scores on the DRS in participants with less severe index injuries and lower mean Cognitive FIM in participants with more severe index injuries. CONCLUSION: Multiple brain injuries, particularly those of moderate or greater severity, have a significantly greater impact on patients' level of functioning compared with a single injury, but not the rate or shape of recovery.

ABSTRACT

We compared two treatments for depression and/ or anxiety in chronic moderate to severe traumatic brain injury (TBI) (Clinicaltrials.gov NCT02061553). Fifty-nine participants were randomized 2:1 to a single session of Behavioural Activation followed by 8 weeks of daily SMS (text) messages in the form of implementation intentions supporting individualized goals for increased rewarding/ meaningful activities (INT), or a single (attention control) session focused on the importance of motivation followed by 8 weeks of motivational SMS messages (MOT). Both conditions resulted in modestly improved emotional status. The INT condition led to more exposure to environmental reward and greater productivity. Gains in both conditions were of questionable clinical significance but suggested different mechanisms of action, which should be confirmed by further research. The delivery of frequent text messages proved to be a very feasible means of supporting treatment in this population.

ABSTRACT

PURPOSE/OBJECTIVE: To examine the relationship of cognitive status to employment outcomes at 1-year post moderate-severe traumatic brain injury (TBI), using a brief telephone-administered instrument. Research Method/Design: Prospective longitudinal study in which 320 people with moderate-severe TBI, all employed at injury, were enrolled during inpatient rehabilitation and evaluated at 1-year postinjury. Follow-up measures included whether and when participants had returned to work (RTW), and cognitive status assessed with the Brief Test of Adult Cognition by Telephone (BTACT). Multivariable logistic regression and survival analyses were used to assess the contribution of BTACT (overall and subscale scores) to employment outcomes, controlling for covariates with known associations to those outcomes, including demographic variables, injury severity, and driving status. RESULTS: Fewer than 40% of participants (n = 124) were employed at 1-year follow-up. BTACT scores were strongly associated with RTW even after controlling for known covariates. Females had faster and higher rates of RTW compared to males. Resumption of driving and injury severity were also related to RTW. CONCLUSIONS/IMPLICATIONS: Neurocognitive status is a potentially modifiable factor with an important relationship to RTW following TBI. Vocational rehabilitation efforts should provide cognitive remediation or compensation as well as addressing transportation barriers. As a brief telephone-based assessment, the BTACT offers a new and efficient tool for evaluation of episodic memory and executive function.

ABSTRACT

Objective: To explore the experience of work-related stress in brain injury professionals and to identify the contributing factors to work-related stress. Methods: 17 brain injury professionals participated in one-time interviews conducted either in person or utilising video conferencing. The data were analysed utilising a Grounded Theory approach. Results: Participants reported that working in brain injury rehabilitation is difficult due to the complex and unpredictable nature of brain injury. The impact of limited funding and resources was endorsed by all participants as the most stressful aspect of working in this field. Emotional experiences associated with treating survivors and organisational factors increase the risk for work-related stress. Brain injury professionals rely on support provided by coworkers and supervisors. Conclusion: This study provides a deeper understanding of work-related stress and challenges of working in the brain injury rehabilitation field, as well as appreciation for the personal and organisational strategies that may help to offset stress. The unpredictable nature of working in brain injury rehabilitation impacted professionals at the micro, mezzo, and macro levels of practice. Overall, it was apparent that the participants interviewed were highly resilient individuals, demonstrating acceptance and flexibility in the limitations they face working in the field of brain injury rehabilitation.

ABSTRACT

Traumatic axonal injury (TAI), a signature injury of traumatic brain injury (TBI), is increasingly known to involve myelin damage. The objective of this study was to demonstrate the clinical relevance of myelin water imaging (MWI) by first quantifying changes in myelin water after TAI and then correlating those changes with measures of injury severity and neurocognitive performance. Scanning was performed at 3 months post-injury in 22 adults with moderate to severe diffuse TBI and 30 demographically matched healthy controls using direct visualization of short transverse component (ViSTa) MWI. Fractional anisotropy (FA) and radial diffusivity (RD) were also obtained using diffusion tensor imaging. Duration of post-traumatic amnesia (PTA) and cognitive processing speed measured by the Processing Speed Index (PSI) from Wechsler Adult Intelligence Scale-IV, were assessed. A between-group comparison using Tract-Based Spatial Statistics revealed that there was a widespread reduction of apparent myelin water fraction (aMWF) in TBI, consistent with neuropathology involving TAI. The group difference map of aMWF yielded topography that was different from FA and RD. Importantly, aMWF demonstrated significant associations with PTA (r = -0.564, p = .006) and PSI (r = 0.452, p = .035). In conclusion, reduced myelin water, quantified by ViSTa MWI, is prevalent in moderate-to-severe diffuse TBI and could serve as a potential biomarker for injury severity and prediction of clinical outcomes.

ABSTRACT

OBJECTIVE: To explore associations of specific physical and neuropsychiatric medical conditions to motor and cognitive functioning and life satisfaction over the first 10 years following traumatic brain injury (TBI). SETTING: Telephone follow-up through 6 TBI Model System centers. PARTICIPANTS: In total, 404 individuals or proxies with TBI enrolled in the TBI Model System longitudinal study participating in 10-year follow-up. DESIGN: Individual growth curve analysis. MAIN MEASURES: FIM Motor and Cognitive subscales, Satisfaction With Life Scales, and Medical and Mental Health Comorbidities Interview. RESULTS: Hypertension, diabetes, cancers, rheumatoid arthritis, and anxiety negatively affected the trajectory of motor functioning over time. Diabetes, cancers, chronic bronchitis, anxiety, and depression negatively impacted cognitive functioning. Numerous neuropsychiatric conditions (sleep disorder, alcoholism, drug addiction, anxiety, panic attacks, posttraumatic stress disorder, depression, and bipolar disorder), as well as hypertension, liver disease, and cancers, diminished life satisfaction. Other medical conditions had a negative effect on functioning and satisfaction at specific follow-up periods. CONCLUSION: Natural recovery after TBI may include delayed onset of functional decline or early recovery, followed by progressive deterioration, and is negatively affected by medical comorbidities. Results contribute to the growing evidence that TBI is most appropriately treated as a chronic medical condition complicated by a variety of comorbid conditions.

ABSTRACT

OBJECTIVES: Individuals with moderate-severe traumatic brain injury (TBI) experience a transitory state of impaired consciousness and confusion often called posttraumatic confusional state (PTCS). This study examined the neuropsychological profile of PTCS. METHODS: Neuropsychometric profiles of 349 individuals in the TBI Model Systems National Database were examined 4 weeks post-TBI (±2 weeks). The PTCS group was subdivided into Low (n=46) and High Performing PTCS (n=45) via median split on an orientation/amnesia measure, and compared to participants who had emerged from PTCS (n=258). Neuropsychological patterns were examined using multivariate analyses of variance and mixed model analyses of covariance. RESULTS: All groups were globally impaired, but severity differed across groups (F(40,506)=3.44; p<.001; ŋp 2 =.206). Rate of forgetting (memory consolidation) was impaired in all groups, but failed to differentiate them (F(4,684)=0.46; p=.762). In contrast, executive memory control was significantly more impaired in PTCS groups than the emerged group: Intrusion errors: F(2,343)=8.78; p<.001; ŋ p 2=.049; False positive recognition errors: F(2,343)=3.70; p<.05; ŋp 2=.021. However, non-memory executive control and other executive memory processes did not differentiate those in versus emerged from PTCS. CONCLUSIONS: Executive memory control deficits in the context of globally impaired cognition characterize PTCS. This pattern differentiates individuals in and emerged from PTCS during the acute recovery period following TBI. (JINS, 2019, 25, 302-313).

ABSTRACT

OBJECTIVE: To examine the prevalence of selected medical and psychiatric comorbidities that existed prior to or up to 10 years following traumatic brain injury (TBI) requiring acute rehabilitation. DESIGN: Retrospective cohort. SETTING: Six TBI Model Systems (TBIMS) centers. PARTICIPANTS: In total, 404 participants in the TBIMS National Database who experienced TBI 10 years prior. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Self-reported medical and psychiatric comorbidities and the onset time of each endorsed comorbidity. RESULTS: At 10 years postinjury, the most common comorbidities developing postinjury, in order, were back pain, depression, hypertension, anxiety, fractures, high blood cholesterol, sleep disorders, panic attacks, osteoarthritis, and diabetes. Comparing those 50 years and older to those younger than 50 years, diabetes (odds ratio [OR] = 3.54; P = .0016), high blood cholesterol (OR = 2.04; P = .0092), osteoarthritis (OR = 2.02; P = .0454), and hypertension (OR = 1.84; P = .0175) were significantly more prevalent in the older cohort while panic attacks (OR = 0.33; P = .0022) were significantly more prevalent in the younger cohort. No significant differences in prevalence rates between the older and younger cohorts were found for back pain, depression, anxiety, fractures, or sleep disorders. CONCLUSIONS: People with moderate-severe TBI experience other medical and mental health comorbidities during the long-term course of recovery and life after injury. The findings can inform further investigation into comorbidities associated with TBI and the role of medical care, surveillance, prevention, lifestyle, and healthy behaviors in potentially modifying their presence and/or prevalence over the life span.
