Traumatic Brain Injury and Depression in a Community-Based Sample: A Cohort Study Across the Adult Life Span

Interventions that aim to increase social participation through recreation or leisure activity for adults with moderate to severe traumatic brain injury: a scoping review

PURPOSE

Social isolation and reduced social participation are common after traumatic brain injury (TBI). Developing interventions that aim to increase social participation through recreation or leisure activities continues to be challenging. This scoping review was conducted to provide an overview of interventions used to increase social participation through in-person recreation or leisure activity for adults with moderate to severe TBI living in the community.

METHODS

Using the Arksey and O'Malley framework, a scoping review of the literature published from 2005 to 2023 was conducted across four databases: Medline, CINAHL, PsycINFO and Scopus. Quality appraisals were conducted for included studies.

RESULTS

Following the removal of duplicates, 10,056 studies were screened and 52 were retained for full-text screening. Seven papers were included in the final review. Studies varied with respect to the type of intervention and program outcomes. The interpretation was impeded by study quality, with only two studies providing higher levels of evidence. Barriers and facilitators to successful program outcomes were identified.

CONCLUSIONS

Few studies with interventions focused on increasing social participation in leisure or recreation activity were identified. Further research incorporating mixed methods and longitudinal design to evaluate effectiveness over time is needed to build the evidence base for increasing social participation through leisure activity.

Adolescent alcohol and cannabis use as risk factors for head trauma in the Northern Finland Birth Cohort study 1986

BACKGROUND

The aim of this study was to assess the associations between cannabis use and frequency of alcohol intoxication in adolescence with the risk of traumatic brain injury and craniofacial fractures in early adulthood. Hypothesis was that using alcohol and cannabis in adolescence could increase the risk for head traumas.

METHODS

Data from the Northern Finland Birth Cohort 1986 (n = 9432 individuals) were used to investigate the prospective association between the self-reported frequency of alcohol intoxication (n = 6472) and cannabis use (n = 6586) in mid-adolescence and register-based, head trauma diagnoses by ages 32-33 years. To test the robustness of these associations, the statistical models were adjusted for a range of other confounders such as illicit drug use, previous head trauma and self-reported mental health problems.

RESULTS

In multivariate analyses, cannabis use was statistically significantly associated with a greater risk of traumatic brain injury among females [hazard ratio (HR) 1.9, 95% confidence interval (CI) 1.1-3.2, P = 0.024). Frequent alcohol intoxication was a statistically significant independent risk factor for both traumatic brain injury (HR 2.6, 95% CI 1.7-3.9, P < 0.001) and craniofacial fractures (HR 2.7, 95% CI 1.6-4.8, P < 0.001) among males.

CONCLUSIONS

Cannabis use in adolescence appears to associate independently with elevated risk for traumatic brain injury among females, and frequent alcohol intoxication in adolescence seems to associate with elevated risk of both traumatic brain injury and craniofacial fractures among males.

Interaction between APOE ɛ4 and Age Is Associated with Emotional Distress One Year after Moderate-Severe Traumatic Brain Injury

Emotional distress is common following moderate-severe traumatic brain injury (TBI) and is associated with poorer post-injury outcomes. Previously investigated sociodemographic, psychological, and injury-related factors account for only a small proportion of variance in post-TBI emotional distress, highlighting a need to consider other factors such as genetic factors. The apolipoprotein E gene (APOE) has been commonly studied in the TBI literature, with the ɛ4 allele linked to worse neuronal repair and recovery. Few studies have investigated the potential relationship between APOE ɛ4 and emotional distress after moderate-severe TBI, and results have been varied. We examined whether APOE ɛ4 was associated with emotional distress 1 year following moderate-severe TBI, and whether this relationship was moderated by age, sex, and TBI severity (as indexed by the duration of post-traumatic amnesia [PTA]). Moderate-severe TBI survivors provided saliva samples following inpatient admission to a TBI rehabilitation hospital. They completed a self-report measure of emotional distress, the Hospital Anxiety and Depression Scale (HADS), at a follow-up interview ∼1 year post-injury. Complete genetic and follow-up data were available for 441 moderate-severe TBI survivors (mean age = 39.42 years; 75% male). We constructed a linear regression model that included APOE ɛ4 carriage status (carrier vs. non-carrier) and interactions with age, sex, and TBI severity (APOE × age, APOE × sex, APOE × age × sex, and APOE × PTA duration) to predict total score on the HADS, while covarying for the main effects of age, sex, PTA duration, and previous head injury. There was a significant main effect of APOE ɛ4, whereby ɛ4 carriers reported less emotional distress than non-carriers (p = 0.04). However, we also found a significant interaction with age such that APOE ɛ4 carriers reported increasingly greater emotional distress with older age compared with non-carriers (p = 0.01). A sensitivity analysis (n = 306) suggested that the APOE × age interaction, and main effects of age and previous head injury, were not unique to individuals with pre-injury mental health problems (n = 136). However, the main effect of APOE ɛ4 was no longer significant when individuals with pre-injury mental health problems were removed. Our findings highlight the importance of considering moderation of genetic associations, suggesting that APOE ɛ4 may be a risk factor for emotional distress specifically among older survivors of moderate-severe TBI. If these findings can be independently replicated, APOE ɛ4 carriage status, interpreted in the context of age, could be incorporated into risk prediction models of emotional distress after moderate-severe TBI, enhancing targeted early detection and intervention efforts.

Incidence of Depression after Traumatic Brain Injury: A Nationwide Longitudinal Study of 2.2 Million Adults

Although improvements in acute care for traumatic brain injury (TBI) have increased the patient survival rate, many survivors often suffer from neuropsychiatric sequelae such as depression. This study investigated the influence of TBI on the risk of depression using South Korean nationwide data. Data were extracted from the National Health Insurance Service database for patients who experienced TBI from 2010 to 2017 (n = 1,141,593) and for 1:1 matched controls without TBI (n = 1,141,593). Patients under 18 years old or with a history of depression were excluded. TBI was used as a time-varying exposure and a time-dependent Cox regression model was adopted. Age, sex, insurance premium and type, region of residence, past psychiatric diseases, and Charlson Comorbidity Index were adjusted. The incidence of depression in the patients with TBI and matched controls was 34.60 and 21.42 per 1000 person-years, respectively. The risk of depression was higher in the patients with TBI (hazard ratio [HR] 1.19, 95% confidence interval [CI] = 1.18-1.20) than in the matched control group. After stratification by sex and age, the risk was higher in men and the younger age group. In subgroup analyses, patients with skull fracture showed the highest risk of depression. Notably, during the first year after TBI, the depression risk was almost 11 times higher than that in the matched control group (HR 11.71, 95% CI = 11.54-11.87). Our findings highlight a significant association of TBI with an increased risk of subsequent depression. Therefore, continuous awareness with regard to patients' mental health is needed.

Lifetime History of Traumatic Brain Injury and Behavioral Health Problems in a Population-Based Sample

OBJECTIVE

To investigate the relationships between indices of lifetime history of traumatic brain injury (TBI) exposure and measures of behavioral health status among Ohioans.

PARTICIPANTS

A random sample (n = 6996) of Ohioans contacted to complete the 2014 Ohio Behavioral Risk Factors Surveillance System (BRFSS).

DESIGN

A cross-sectional survey.

MAIN MEASURES

The Ohio State University TBI Identification Method adapted for BRFSS module and BRFSS behavioral indicators.

RESULTS

After demographic adjustment, lifetime history of TBI was found to be associated with increased odds of binge drinking, heavy drinking, smoking, a depressive disorder, or mental health not being good (≥2 days and ≥14 days in last 30 days). Mixed findings across behavioral indicators were observed in regard to number and severity of injury. Age at first injury showed no remarkable associations with the behavioral health indicators.

CONCLUSIONS

Ohioans who have sustained at least one TBI with loss of consciousness in their lifetime are at increased risk for poor behavioral health, including alcohol misuse, smoking, and depression. The findings underscore the need for community-based mental health treatment programs to screen for TBI history in their intake evaluations, and to train clinicians on the provisions of accommodations for cognitive and behavioral deficits.

The additional burden of PTSD on functioning and depression in veterans with traumatic brain injury

BACKGROUND

Many United States veterans and active military with a history of traumatic brain injury (TBI) also experience challenges from comorbid posttraumatic stress disorder (PTSD), yet the additional burden of PTSD is not clear.

PURPOSE

To address this knowledge gap, this study examined the relationship of PTSD to cognitive, social, and physical functioning and depressive symptoms in veterans recently diagnosed with TBI.

METHODS

Veterans were recruited from a VA rehabilitation clinic. The Patient Competency Rating Scale and Center for Epidemiologic Studies Depression Scale measured functioning and depression, respectively. Chart review captured PTSD diagnosis.

FINDINGS

In the sample of 83 veterans, 65% had a current PTSD diagnosis. After controlling for sociodemographic variables and TBI severity, PTSD was a significant predictor of lower cognitive, social, and physical functioning and higher depressive symptomatology.

DISCUSSION

Clinicians should incorporate PTSD assessment in their work with veterans with TBI. Integrated behavioral health and rehabilitation interventions that provide strategies for veterans to manage TBI symptoms and PTSD are critical.

Association of remote traumatic brain injury and military employment with late-life trajectories of depressive symptom severity

BACKGROUND

Traumatic brain injury (TBI) and military service are common lifetime exposures among current older adults that may affect late-life mental health. The objective of the present study was to evaluate the association between TBI with loss of consciousness (LOC) and military employment and late-life depressive symptom severity trajectory.

METHODS

1445 males and 2096 females adults at least 65 years old without dementia or recent TBI were enrolled and followed biennially for up to 10 years in the Adult Changes in Thought study from Kaiser Permanente Washington in Seattle, Washington.

RESULTS

Using group-based trajectory modeling, we documented four distinct depressive symptom severity trajectories that followed a similar course in males and females (Minimal, Decreasing, Increasing, and Persistent). In multinomial regression analyses, TBI with LOC in males was associated with greater likelihood of Persistent versus Minimal depressive symptom severity compared to individuals without TBI (OR = 1.51, 95% CI: 1.01, 2.27; p=0.046). Males reporting past military employment had greater likelihood of Decreasing versus Minimal depressive symptom severity compared to individuals without past military employment (OR = 1.54, 95% CI: 1.03, 2.31; p=0.035). There was no association between TBI or military employment and depression trajectories in females, and no evidence of effect modification by age or between exposures.

LIMITATIONS

Lifetime history of TBI was ascertained retrospectively and may be subject to recall bias. Also, past military employment does not presuppose combat exposure.

CONCLUSIONS

Remote TBI and past military employment are relevant to late-life trajectories of depressive symptom severity in dementia-free older males.

Quality of life after traumatic brain injury: a cross-sectional analysis uncovers age- and sex-related differences over the adult life span

Traumatic brain injury (TBI) is the leading cause of disability in the working population and becomes increasingly prevalent in the elderly. Thus, TBI is a major global health burden. However, age- and sex-related long-term outcome regarding patient’s health-related quality of life (HRQoL) is yet not clarified. In this cross-sectional study, we present age- and sex-related demographics and HRQoL up to 10 years after TBI using the Quality of Life after Brain Injury (QOLIBRI) instrument. The QOLIBRI total score ranges from zero to 100 indicating good (≥ 60), moderate (40–59) or unfavorable (< 40) HRQoL. Two-thirds of the entire chronic TBI cohort (102 males; 33 females) aged 18–85 years reported good HRQoL up to 10 years after TBI. TBI etiology differed between sexes with females suffering more often from traffic- than fall-related TBI (p = 0.01) with increasing prevalence during aging (p = < 0.001). HRQoL (good/moderate/unfavorable) differed between sexes (p < 0.0001) with 17% more females reporting moderate outcome (p = 0.01). Specifically, older females (54–76-years at TBI) were affected, while males constantly reported good HRQoL (p = 0.017). Cognition (p = 0.014), self-perception (p = 0.009), and emotions (p = 0.016) rather than physical problems (p = 0.1) constrained older females’ HRQoL after TBI. Experiencing TBI during aging does not influence HRQoL outcome in males but females suggesting that female brains cope less well with a traumatic injury during aging. Therefore, older females need long-term follow-ups after TBI to detect neuropsychiatric sequels that restrict their quality of life. Further investigations are necessary to uncover the mechanisms of this so far unknown phenomenon.

Treatment of Depression After Traumatic Brain Injury: A Systematic Review Focused on Pharmacological and Neuromodulatory Interventions

BACKGROUND

Depression is the most common psychiatric sequela after traumatic brain injury (TBI) and poses a variety of treatment challenges. There is a lack of clinical trials focused on biological interventions used to manage TBI depression.

OBJECTIVE

The aim of this systematic review is to summarize the current evidence of psychotropic and neuromodulatory interventions used to treat TBI depression and to provide directions for future research.

METHODS

Key words were used to describe the following search terms: "traumatic brain injury", "depression", "pharmacological/drug therapy", and "neuromodulation". Studies focused on pharmacotherapy or neuromodulation in TBI depression were identified in 5 databases: Medline (PubMed), EMBASE (Embase.com), the Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Cochrane Methodology Register), PsycINFO (EbscoHost), and Web of Science. Article inclusion/exclusion using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)-based systematic protocol of extraction and evaluation was applied. Level of evidence for each study was determined using the American Academy of Neurology criteria.

RESULTS

The initial search provided 1473 citations. Twenty-two studies met inclusion criteria. Sixteen studies explored pharmacological interventions with emphasis on serotonergic agents. Results between studies were conflicting, and interventions did not always outperform placebos, although sertraline provided the highest level of evidence for treatment of TBI depression. Six studies examining neuromodulatory interventions show preliminary evidence of efficacy with a range of interventions and modes of delivery used.

CONCLUSIONS

Additional research including large-sample randomized-controlled trials using pharmacological, neuromodulation, or combination treatment is needed. These studies should incorporate premorbid psychosocial functioning, preinjury psychiatric disease, cognitive deficits, and functional recovery when examining outcomes.

Psychiatric Disorders After Traumatic Brain Injury: A Nationwide Population-Based Cohort Study and the Effects of Rehabilitation Therapies

OBJECTIVE

To investigate the risk of psychiatric disorders after traumatic brain injury (TBI), and to clarify whether the post-TBI rehabilitation was associated with a lower risk of developing psychiatric disorders.

DESIGN

A register-based, retrospective cohort design.

SETTING

Using data from the National Health Insurance Research Database of Taiwan, we established an exposed cohort with TBI and a nonexposed group without TBI matched by age and year of diagnosis between 2000 and 2015.

PARTICIPANTS

This study included 231,894 patients with TBI and 695,682 patients without TBI (N=927,576).

INTERVENTIONS

Rehabilitation therapies in TBI patients.

MAIN OUTCOME MEASURES

A multivariable Cox proportional hazards regression model was used to compare the risk of developing psychiatric disorders.

RESULTS

The incidence rate of psychiatric disorders was higher in the TBI group than the control group. Compared with the control group, the risk of psychiatric disorders in the TBI group was twofold (hazard ratio [HR]=2.072; 95% confidence interval [95% CI], 1.955-2.189; P<.001). Among the participants with TBI, 49,270 (21.25%) had received rehabilitation therapy and had a lower risk of psychiatric disorders (HR=0.691; 95% CI, 0.679-0.703; P<.001). In the subgroup analysis, the medium- to high-level intensity rehabilitation therapy was associated with lower risks of psychiatric disorder (HR=0.712 and 0.568, respectively), but there was no significant finding in the low-intensity group.

CONCLUSIONS

We found that TBI was associated with a high risk for developing psychiatric disorders, and that the post-TBI rehabilitation significantly reduced the risk of psychiatric disorders in a dose-dependent manner.

Anxiety and comorbid depression following traumatic brain injury in a community-based sample of young, middle-aged and older adults

BACKGROUND

Anxiety is common following a traumatic brain injury (TBI), but who is most at risk, and to what extent, is not well understood.

METHODS

Longitudinal data from a randomly-selected community sample (Wave 1: 7397, Wave 2: 6621 and Wave 3: 6042) comprising three adult cohorts (young: 20-24 years of age, middle-aged: 40-44, older: 60-64), were analysed. The association between TBI history, anxiety and comorbid depression was assessed, controlling for age, sex, marital/employment status, medical conditions, recent life events, alcohol consumption, social support and physical activity.

RESULTS

Thirteen percent of the sample had sustained a TBI by Wave 3, 35% of whom had sustained multiple TBIs. Cross-sectional analyses revealed that clinically-significant anxiety was more common in people who had sustained a TBI. Longitudinal analyses demonstrated an increased risk of anxiety post-TBI, even after controlling for potential demographic, health and psychosocial confounds. Anxiety was more common than depression, although 10% of those with a TBI experienced comorbid anxiety/depression.

LIMITATIONS

TBIs were not medically confirmed and anxiety and depression were only assessed every four years by self-report, rather than clinical interview. Sample attrition resulted in the retention of healthier individuals at each wave.

CONCLUSIONS

TBIs are associated with a lifelong increased risk of experiencing clinically-significant anxiety, highlighting the chronic nature of TBI sequelae. Positive lifestyle changes (e.g., increasing physical activity, reducing alcohol consumption) may decrease the risk of anxiety problems in the early years after a TBI. Comorbid anxiety and depression was common, indicating that both should be monitored and treated.
