History of traumatic brain injury in prison populations: A systematic review

Attentional Orienting and Disfluency-Related Memory Boost Are Intact in Adults With Moderate-Severe Traumatic Brain Injury

PURPOSE

Traumatic brain injury (TBI) is associated with a range of cognitive-communicative deficits that interfere with everyday communication and social interaction. Considerable effort has been directed at characterizing the nature and scope of cognitive-communication disorders in TBI, yet the underlying mechanisms of impairment are largely unspecified. The present research examines sensitivity to a common communicative cue, disfluency, and its impact on memory for spoken language in TBI.

METHOD

Fifty-three participants with moderate-severe TBI and 53 noninjured comparison participants listened to a series of sentences, some of which contained disfluencies. A subsequent memory test probed memory for critical words in the sentences.

RESULTS

Participants with TBI successfully remembered the spoken words (b = 1.57, p < .0001) at a similar level to noninjured comparison participants. Critically, participants with TBI also exhibited better recognition memory for words preceded by disfluency compared to words from fluent sentences (b = 0.57, p = .02).

CONCLUSIONS

These findings advance mechanistic accounts of cognitive-communication disorder by revealing that, when isolated for experimental study, individuals with moderate-severe TBI are sensitive to attentional orienting cues in speech and exhibit enhanced recognition of individual words preceded by disfluency. These results suggest that some aspects of cognitive-communication disorders may not emerge from an inability to perceive and use individual communication cues, but rather from disruptions in managing (i.e., attending, weighting, integrating) multiple cognitive, communicative, and social cues in complex and dynamic interactions. This hypothesis warrants further investigation.

A literature review of outcome and treatment options after acquired brain injury: Suggestions for adult offenders using knowledge from the general population

BACKGROUND

Acquired brain injury (ABI) is a major health problem, often with negative effects on behaviour and mental health as well as cognition. Prevalence of ABI is exceptionally high among offenders and increases their re-offending risk. Information on risk factors for ABI and its outcomes among offenders that could guide effective treatment for them is, nevertheless, scarce and dispersed. However, there is a more substantial literature about the general population that could inform work with brain-injured offenders, especially when selecting for samples or subgroups with similar relevant characteristics, such as lower socio-economic status (SES), pre-injury lower tested intelligence score (<85) and pre-injury mental health problems.

AIMS

To explore brain injury data from non-offender samples of otherwise similar socio-economic and mental health and ability characteristics to offenders then, first, to describe their untreated outcomes and, secondly, outcomes after frequently used interventions in these circumstances, noting factors associated with their effectiveness.

METHOD

Three databases were systematically searched for the years 2010-2022; first, using terms for brain injury or damage and cognitive (dys)function, mental health or quality of life. Second, in a separate search, we used these terms and terms for interventions and rehabilitation. In the second review, studies were selected for clear, distinguishable data on age, sex, SES and lifestyle factors to facilitate inferences for offenders. A narrative analytical approach was adopted for both reviews.

RESULTS

Samples with characteristics that are typical in offender groups, including lower SES, lower pre-injury intelligence quotient (<85), prior cognitive impairments and prior mental health problems, had poorer cognitive and behavioural outcomes following ABI than those without such additional problems, together with lower treatment adherence. With respect to treatment, adequate motivation and self-awareness were associated with better cognitive and behavioural outcomes than when these were low or absent, regardless of the outcome measured.

CONCLUSIONS

More complex pre-injury mental health problems and social disadvantages typical of offenders are associated with poorer post-brain injury recovery. This paper adds to practical knowledge by bringing together work that follows specific outcome trajectories. Overall, succesful ABI-interventions in the general population that aim at pre-injury difficulties comparable to those seen among offenders, show that personalising injury-specific treatments and taking account of these difficulties, maximised positive outcomes.

Characteristics of forensic psychiatric patients with a neurocognitive disorder

BACKGROUND

Emotional and behavioural disturbances accompanying neurocognitive disorders may sometimes lead to a criminal offence. Our knowledge of this specific forensic subpopulation is lagging behind the knowledge on, and attention for, 'classic' psychiatric disorders in forensic populations.

AIMS

To gain knowledge on the prevalence and characteristics of individuals with neurocognitive disorders in the forensic population.

METHOD

This retrospective database study uses an anonymised data-set of the National Database of penitentiary psychiatric centres (PPC) (N = 8391), which collects data on all patients admitted to one of the four PPCs (mental health clinics within the prison system) in The Netherlands since May 2013. Inclusion criterion for this study was the presence of a Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision (DSM-IV-TR) or Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) diagnostic code belonging to the category of neurocognitive disorders.

RESULTS

A DSM-IV-TR or DSM-5 diagnostic code of a neurocognitive disorder was classified in 254 out of 8391 unique individuals, resulting in a prevalence of 3.0% in the total PPC population. The most prevalent diagnosis was unspecified neurocognitive disorder (59.1%). The neurocognitive disorder group significantly differed from a random control group from the database (n = 762) on demographic, clinical and criminological variables.

CONCLUSIONS

The prevalence of neurocognitive disorders in this real-world clinical sample is remarkably lower than in two earlier studies in similar populations. Also remarkable is the relatively high prevalence of an unspecified neurocognitive disorder. These findings lead us to hypothesise that neurocognitive disorders may be underdiagnosed in this population. Forensic psychiatric settings should evaluate whether they have sufficient expertise available in neuropsychological assessment.

Forensic neurology: a distinct subspecialty at the intersection of neurology, neuroscience and law

Neurological evidence is increasingly used in criminal cases to argue that a defendant is less responsible for their behaviour, is not competent to stand trial or should receive a reduced punishment for the crime. Unfortunately, neurologists are rarely involved in such cases despite having the expertise to help to inform these decisions in court. In this Perspective, we advocate for the development of 'forensic neurology', a subspecialty of neurology focused on using neurological clinical and scientific expertise to address legal questions for the criminal justice system. We review literature suggesting that the incidence of criminal behaviour is higher in people with certain neurological disorders than the general public and that undiagnosed neurological abnormalities are common in people who commit crimes. We discuss the need for forensic neurologists in criminal cases to provide an opinion on what neurological diagnoses are present, the resulting symptoms and ultimately whether the symptoms affect legal determinations such as criminal responsibility or competency.

Traumatic brain injury and mental health outcomes among recently incarcerated men

This study examined the association between experiencing a traumatic brain injury (TBI) before or during incarceration and several postrelease negative mental health consequences in a cohort of men recently released from prison. The goal of the study was to explicate the variety of mental health-related issues incurring a TBI has on one's ability to successfully reintegrate back into society following incarceration. Using data from the LoneStar Project, we used ordinary least squares regression and logistic regression to assess the prevalence of depressive symptoms, stress, trauma flashbacks, and psychosis in a representative sample of men released from Texas prisons (N = 498) approximately 9 months post-prison release. Recently released men with a history of head injury exhibited higher levels of depression, B = 0.204, 95% CI [.071, .337]; stress, B = 0.266, 95% CI [.116, .416]; experiencing trauma-related flashbacks, odds ratio (OR) = 2.950, 95% CI [1.740, 5.001]; and psychosis, OR = 3.093, 95% CI [1.601, 5.975], compared to their non-head-injured counterparts. TBIs-whether sustained before or during incarceration-pose significant risks for adverse mental health outcomes, particularly for recently released individuals during the already challenging and strained period of reintegration.

Self-reported traumatic brain injury in a sample of impulsive violent offenders: neuropsychiatric correlates and possible "dose effects"

Background

Traumatic brain injury (TBI) is a major public health problem that may be associated with numerous behavioral problems, including impulsivity, aggression and violence. Rates of self-reported TBI are high within offender populations, but the extent to which TBI is causally implicated in causing illegal behavior is unclear. This study examined the psychological and functional correlates of histories of traumatic brain injury in a sample of impulsive violent offenders.

Methods

Study participants, all men, had been recruited to participate in a randomized controlled trial of sertraline to reduce recidivism. Study entry criteria were an age of at least 18 years, a documented history of two or more violent offenses and a score of 70 or above on the Barratt Impulsiveness Scale. An extensive list of standardized questionnaires was administered to obtain information on previous TBI and other neuropsychiatric conditions or symptoms.

Results

In the sample of 693 men, 66% were aged between 18 and 35 years old, and 55% gave a history of TBI ("TBI+"). Overall, 55% of study participants reported at least one TBI. High levels of neuropsychiatric symptomatology were reported. In 75% of TBI+ individuals, their most severe TBI (by self-report) was associated with loss of consciousness (LOC) < 30 min. Compared to TBI- (those without history of TBI) participants, TBI+ individuals were more impulsive (Eysenck Impulsivity), irritable, angry, and reported higher levels of assaultive behavior, depressive symptomology, alcohol use disorder, suicidal ideation, suicide attempts, and lower quality of life. Potential "dose effects" of TBI severity and frequency in terms of neuropsychiatric symptomatology were identified.

Conclusion

Like other studies of offender populations, single and multiple TBIs were very common. The associations of TBI, TBI severity, and TBI frequency (i.e., TBI "burden") with adverse neuropsychiatric phenomena suggest TBI contributes importantly to offender morbidity but the select nature of the sample and cross-sectional study design constrain the interpretation of these findings.

Psychiatric sequelae of traumatic brain injury - future directions in research

Despite growing appreciation that traumatic brain injury (TBI) is an important public health burden, our understanding of the psychiatric and behavioural consequences of TBI remains limited. These changes are particularly detrimental to a person's sense of self, their relationships and their participation in the wider community, and they continue to have devastating individual and cumulative effects long after TBI. This Review relates specifically to TBIs that confer objective clinical or biomarker evidence of structural brain injury; symptomatic head injuries without such evidence are outside the scope of this article. Common psychiatric, affective and behavioural sequelae of TBI and their proposed underlying mechanisms are outlined, along with a brief overview of current treatments. Suggestions for how scientists and clinicians can work together in the future to address the chasms in clinical care and knowledge are discussed in depth.

Adverse Childhood Experiences and Offending as a Function of Acquired Brain Injury Among Men in a High Secure Forensic Psychiatric Hospital

BACKGROUND

Acquired brain injury (ABI) is a serious problem that disproportionately affects individuals in correctional services, but relatively little is known about ABI risks and correlates in forensic psychiatric services.

METHODS

We conducted a retrospective chart review of all admissions to a high secure forensic hospital in Ontario, Canada from January 2009 to December 2012 (n = 637) and collected data on ABI, psychiatric diagnoses, developmental disadvantage, criminal offending, and in-hospital aggression. A k-means cluster analysis was employed to assess risk factors by which men with ABI could be identified and multivariate general linear models were used to identify ABI-related differences in offending history and in-hospital aggression.

RESULTS

One-fifth of the men had a documented ABI indicator. Based on our cluster analysis, ABI was more likely to be identified by greater adverse childhood experiences (ACEs), more health problems from pregnancy to childhood, and lower socioeconomic status, suggesting that ABI within the forensic context is associated with greater developmental disadvantage. Men with ABI had more serious pre-admission offences, but not more serious admission offences or in-hospital aggression. Men with ABI were more likely than those without to have higher scores on the Violence Risk Appraisal Guide or to be diagnosed with mood and personality disorders, and less likely to have a schizophrenia diagnosis, suggesting an association between ABI and general mental health pathologies but not with psychotic illness.

CONCLUSIONS

The disadvantage of ABI among men in forensic psychiatric hospitals is most likely evinced in antisocial behaviour rather than serious mental illness. Given that ACEs are likely to precede or co-occur with ABI, strategies that mitigate ACEs hold promise for ABI prevention.

Clinical Policy: Critical Issues in the Management of Adult Patients Presenting to the Emergency Department With Mild Traumatic Brain Injury: Approved by ACEP Board of Directors, February 1, 2023 Clinical Policy Endorsed by the Emergency Nurses Association (April 5, 2023)

This 2023 Clinical Policy from the American College of Emergency Physicians is an update of the 2008 “Clinical Policy: Neuroimaging and Decisionmaking in Adult Mild Traumatic Brain Injury in the Acute Setting.” A writing subcommittee conducted a systematic review of the literature to derive evidence-based recommendations to answer the following questions: 1) In the adult emergency department patient presenting with minor head injury, are there clinical decision tools to identify patients who do not require a head computed tomography? 2) In the adult emergency department patient presenting with minor head injury, a normal baseline neurologic examination, and taking an anticoagulant or antiplatelet medication, is discharge safe after a single head computed tomography? and 3) In the adult emergency department patient diagnosed with mild traumatic brain injury or concussion, are there clinical decision tools or factors to identify patients requiring follow-up care for postconcussive syndrome or to identify patients with delayed sequelae after emergency department discharge? Evidence was graded and recommendations were made based on the strength of the available data. Widespread and consistent implementation of evidence-based clinical recommendations is warranted to improve patient care.

High Risk of Substance Use Disorder-Related Outcomes in Veterans Released from Correctional Facilities in Mid to Late Life

BACKGROUND

Veterans Affairs (VA) is likely to encounter a growing number of veterans returning to the community in mid to late life following incarceration (i.e., experiencing reentry). Yet, rates of negative health outcomes due to substance use disorders (SUDs) in this population are unknown.

OBJECTIVE

To determine risk of and risk factors for SUD-related emergency department visits and inpatient hospitalizations (ED/IPH) and overdose death among older reentry veterans compared with never-incarcerated veterans.

DESIGN

Retrospective cohort study using national VA and Medicare healthcare systems data.

PARTICIPANTS

Veterans age  ≥50, incarcerated for  ≤5 consecutive years, and released between October 1, 2010, and September 30, 2017 (N = 18,803), were propensity score-matched 1:5 with never-incarcerated veterans (N = 94,015) on demographic characteristics, reason for Medicare eligibility, and SUD history.

MAIN MEASURES

SUD-related ED/IPH (overall and substance-specific) were obtained from in-/outpatient VA health services and CMS data within the year following release date/index date (through September 30, 2018). Overdose death within 1 year was identified using the National Mortality Data Repository. Fine-Gray proportional hazards regression compared risk of SUD-related ED/IPH and overdose death between the two groups.

RESULTS

The number of SUD-related ED/IPHs and overdose deaths was 2470 (13.1%) and 72 (0.38%) in the reentry sample versus 4402 (4.7%) and 198 (0.21%) in the never-incarcerated sample, respectively. Mid-to-late-life reentry was associated with higher risk of any SUD-related ED/IPH (13,136.2 vs. 2252.8 per 100,000/year; adjusted hazard ratio [AHR] = 2.19; 95% confidence interval [CI] = 2.08, 2.30) and overdose death (382.9 vs. 210.6 per 100,000/year; AHR = 2.24, 95% CI = 1.63, 3.08).

CONCLUSIONS

Older reentry veterans have more than double the risk of experiencing SUD-related ED/IPH (overall and substance-specific) and overdose death, even after accounting for SUD history and other likely confounders. These findings highlight the vulnerability of this population. Improved knowledge regarding SUD-related negative health outcomes may help to tailor VA reentry programming.

The association between self-reported traumatic brain injury, neuropsychological function, and compliance among people serving community sentences

BACKGROUND

Traumatic brain injury is overrepresented in incarcerated samples and has been linked to a number of poor correctional outcomes. Despite this, no research has explored the impact of a recent TBI on compliance outcomes for individuals serving community-based.

METHOD

We screened for a history of TBI in 106 adults on community sentences and collected compliance (arrests, sentence violations) and related variables (e.g., risk scores, substance use) over 6 months. Sixty-four participants also completed the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), the Comprehensive Trail Making Test and Color-Word Inference Test.

RESULTS

A TBI in the last year predicted a significantly higher likelihood of arrest, even when controlling for risk of reconviction and current substance use, but was not associated with non-compliance with sentence conditions nor with performance on the neuropsychological tests. In addition, no significant associations were found between performance on neuropsychological tests and measures of non-compliance.

CONCLUSIONS

TBI in the last year was an independent predictor of arrest. This result suggests that those with a recent TBI on a community sentence may need additional monitoring or support to reduce the risk of reoffending.

Executive functioning as mediator of the association between traumatic brain injury and prison bullying

OBJECTIVE

This study examined whether executive functioning (EF) mediated the relationship between childhood traumatic brain injury (TBI) and engaging in bullying in prison (BP).

PARTICIPANTS

A sample of male adults in custody in Uruguay (N = 236), drawn from five prisons.

METHODS

Inmates filled out self-report questionnaires examining TBI (Head Injury Questionnaire), EF (Behavior Rating Inventory of Executive Function Adult, BRIEF-A) and bullying in prison (Direct and Indirect Prisoner Behavior Checklist - revised, SCALED, DIPC-SCALED-r).

RESULTS

Findings showed that TBI was associated with prison bullying after controlling for age, level of education, socioeconomic status, and civil status. The mediation analysis indicated that the relationship between TBI and bullying was fully mediated via executive impairment, especially through the behavioral regulation component (mainly inhibition and emotional control).

CONCLUSION

These findings suggested that compensating for EF difficulties in adult inmates with brain injuries might help to decrease the bullying in prison.

Rehabilitation among individuals with traumatic brain injury who intersect with the criminal justice system: A scoping review

Traumatic brain injury (TBI), a leading cause of morbidity and mortality globally, is highly prevalent among individuals who intersect with the criminal justice system (CJS). It is well-established that TBI negatively impacts individuals' interactions both within the CJS and upon release and is associated with serious disciplinary charges and higher recidivism rates. Although rehabilitation is fundamental to TBI recovery, it is not known to what extent rehabilitation is available to, or used by, individuals who intersect with the CJS. This scoping review explores the availability and extent of rehabilitation for individuals with TBI who intersect with the CJS, based on available literature. A systematic search of electronic databases (MEDLINE, Embase, Cochrane CENTRAL Register of Clinical Trials, CINAHL, APA PsycINFO, Applied Social Sciences Index and Abstracts, and Proquest Nursing and Allied Health), relevant organizations' websites, and reference lists of eligible articles identified 22 peer-reviewed articles and 2 gray literature reports that met predetermined eligibility criteria. Extracted data were synthesized through a descriptive numerical summary and qualitative content analysis. This review provides evidence that existing rehabilitation interventions are already serving individuals with TBI with a history of CJS involvement; however, they rarely consider or acknowledge TBI or CJS in their interventions. Findings also suggest opportunities to integrate rehabilitation for individuals with TBI who intersect with the CJS through TBI screening, education on TBI within CJS settings, and linkages to the community to facilitate continuity of care. This review also highlights significant gaps in knowledge regarding sex, gender, and other intersecting factors. Research to understand how these experiences impact the rehabilitation process throughout the CJS is urgently needed to enable timely and appropriate rehabilitation and continuity of care for diverse individuals with TBI who intersect with the CJS.

Preliminary findings on TBI knowledge of professionals working with justice-involved youth

Professionals working with justice-involved youth (JIYs) play a critical role in identifying and providing supports and services related to traumatic brain injury (TBI). The aim of this study was to better understand the knowledge of TBI of professionals working with JIYs, a research priority identified by the National Conference of State Legislatures. Fifty employees of an urban juvenile court system completed an online survey about their TBI knowledge. Respondents scored an average of 77.31% correct, yet patterns emerged in item responses and based on participant characteristics that indicate opportunities for training and education on TBI. The results of this preliminary study provide foundational evidence on TBI knowledge of professionals working with JIYs, inform future TBI-related trainings and education provided to professionals working with JIYs, and inform other practices and policies related to JIYs with TBI.

Measuring long-term outcomes after injury: current issues and future directions

Maximizing long-term outcomes for patients following injury is the next challenge in the delivery of patient-centered trauma care. The following review outlines three important components in trauma outcomes: (1) data gathering and monitoring, (2) the impact of traumatic brain injury, and (3) trajectories in recovery and identifies knowledge gaps and areas for needed future research.

The relevance of social and commercial determinants for neurological health

A disconnect has developed over the past two decades between neurological and neuroscientific research, which have seen notable innovation and development, and our increasing understanding of the role of social and commercial determinants of health, including the health of the nervous system. Over the next two decades, grounding neurological research in public health and epidemiological principles can bring about a paradigm shift, away from reductionism, over-medicalisation, and health inequities towards neurological research that reduces inequalities and has true relevance to the populations it aims to serve. People who are involved in neurological and neuroscientific research and practice, as clinicians, researchers, publishers, and funders, can create change by being more aware of the social and commercial determinants of health, reprioritising research funding, and advocating for greater neurological health equity.

White matter integrity in delinquent emerging adults and non-delinquent controls, and its relationship with aggression, psychopathic traits, and cannabis use

Background

Atypical white matter integrity may be one of the biological factors related to delinquency. In adults, decreased white matter integrity has been related to antisocial behavior, but findings from research in adolescent and young adult populations are either mixed or lacking. Here we investigated this association within a naturalistic sample of delinquent young adults (age 18–27).

Methods

In a sample of 95 young adult, delinquent men and 22 age and gender matched controls, we assessed white matter integrity through fractional anisotropy and mean diffusivity measures. We compared white matter integrity between the groups, and within the delinquent group assessed the association between white matter integrity and aggression, psychopathic traits, and cannabis use.

Results

We found no differences in fractional anisotropy or mean diffusivity between delinquent young adults and non-delinquent controls. Additionally, within the group of delinquent young adults, we found no associations between white matter integrity and aggression, psychopathic traits, or cannabis use.

Conclusion

Our null findings suggest that white matter integrity differences may be unrelated to antisocial behavior in emerging adults, and/or that white matter differences between delinquent populations and controls may only arise later in life.

An examination of autonomic and facial responses to prototypical facial emotion expressions in psychopathy

Meta-analyses have found that people high in psychopathy categorize (or “recognize”) others’ prototypical facial emotion expressions with reduced accuracy. However, these have been contested with remaining questions regarding the strength, specificity, and mechanisms of this ability in psychopathy. In addition, few studies have tested holistically whether psychopathy is related to reduced facial mimicry or autonomic arousal in response to others’ dynamic facial expressions. Therefore, the current study presented 6 s videos of a target person making prototypical emotion expressions (anger, fear, disgust, sadness, joy, and neutral) to N = 88 incarcerated adult males while recording facial electromyography, skin conductance response (SCR), and heart rate. Participants identified the emotion category and rated the valence and intensity of the target person’s emotion. Psychopathy was assessed via the Psychopathy Checklist-Revised (PCL-R). We predicted that overall PCL-R scores and scores for the interpersonal/affective traits, in particular, would be related to reduced emotion categorization accuracy, valence ratings, intensity ratings, facial mimicry, SCR amplitude, and cardiac deceleration in response to the prototypical facial emotion expressions. In contrast to our hypotheses, PCL-R scores were unrelated to emotion categorization accuracy, valence ratings, and intensity ratings. Stimuli failed to elicit facial mimicry from the full sample, which does not allow drawing conclusions about the relationship between psychopathy and facial mimicry. However, participants displayed general autonomic arousal responses, but not to prototypical emotion expressions per se. PCL-R scores were also unrelated to SCR and cardiac deceleration. These findings failed to identify aberrant behavioral and physiological responses to prototypical facial emotion expressions in relation to psychopathy.

Protocol for a scoping review on rehabilitation among individuals with traumatic brain injury who intersect with the criminal justice system

Traumatic brain injury (TBI), a leading cause of both death and disability worldwide, is highly prevalent among individuals who intersect with the criminal justice system. TBI is associated with increased behavioural, psychological, or negative outcomes, such as higher rates of mental health problems, aggression, and violent offending that may lead to negative interactions with the criminal justice system, reincarceration, and recidivism. Although rehabilitation is often recommended and holds promise in addressing TBI-related impairments, there is currently a paucity of reviews on rehabilitation for individuals with TBI who intersect with the criminal justice system (CJS). Concurrently, to the best of our knowledge, there is currently no review that considers rehabilitation among individuals with TBI who intersect with all parts of the CJS (i.e., policing, courts, corrections, and parole). This protocol is for a scoping review to address the above gaps, specifically, to identify the types of rehabilitation interventions and/or programs available to, or used by, individuals with TBI who intersect with all parts of the CJS. Primary research articles that meet pre-defined inclusion criteria will be identified from electronic databases (MEDLINE® ALL, Embase and Embase Classic, Cochrane CENTRAL Register of Clinical Trials, CINAHL, APA PsycINFO, Applied Social Sciences Index and Abstracts, Criminal Justice Abstracts, Nursing and Allied Health, and Dissertation and These Global), reference lists of included articles, and scoping or systematic reviews. Grey literature will also be searched to identify non-peer-reviewed reports. Retrieved articles will be screened by two reviewers and any disagreements will be resolved by a third reviewer. Data will be summarized quantitatively and analyzed using content analytic techniques. Intersecting identities will be charted and considered in the analysis. Stakeholders will be engaged to obtain feedback on preliminary results and the implications of findings. The scoping review will summarize the current state of rehabilitation available to, or used by, individuals with TBI who intersect with all parts of the CJS to (a) inform opportunities to integrate rehabilitation in the criminal justice system for diverse individuals and (b) identify opportunities for future research.

Focusing on Formononetin: Recent Perspectives for its Neuroprotective Potentials

Nervous system is the most complex system of the human body, hence, the neurological diseases often lack effective treatment strategies. Natural products have the potential to yield unique molecules and produce integrative and synergic effects compared to standard therapy. Mounting evidence has shown that isoflavonoids contained in traditional medicinal plant or dietary supplementation may play a crucial role in the prevention and treatment of neurological diseases due to their pronounced biological activities correlating to nervous system. Formononetin, a non-steroidal isoflavonoid, is a bioactive constituent of numerous medicinal plants such as red clover (Trifolium pratense) and Astragalus membranaceus. Emerging evidence has shown that formononetin possesses considerable anti-inflammatory, antioxidant and anti-cancer effects. This review intends to analyze the neuropharmacological potential of formononetin on the therapy of nervous system disorders. The neuroprotective properties of formononetin are observed in multiple neurological disorders including Alzheimer’s disease, dementia, cerebral ischemia, traumatic brain injury, anxiety, and depression. The beneficial effects of formononetin are achieved partially through attenuating neuroinflammation and oxidative stress via the related signaling pathway. Despite its evident effects in numerous preclinical studies, the definite role of formononetin on humans is still less known. More well-designed clinical trials are required to further confirm the neuroprotective efficacy and safety profile of formononetin before its application in clinic.

Developing a National Trauma Research Action Plan: Results from the Neurotrauma Research Panel Delphi Survey

BACKGROUND

In 2016, the National Academies of Science, Engineering and Medicine called for the development of a National Trauma Research Action Plan. The Department of Defense funded the Coalition for National Trauma Research to generate a comprehensive research agenda spanning the continuum of trauma and burn care. Given the public health burden of injuries to the central nervous system, neurotrauma was one of 11 panels formed to address this recommendation with a gap analysis and generation of high-priority research questions.

METHODS

We recruited interdisciplinary experts to identify gaps in the neurotrauma literature, generate research questions, and prioritize those questions using a consensus-driven Delphi survey approach. We conducted four Delphi rounds in which participants generated key research questions and then prioritized the importance of the questions on a 9-point Likert scale. Consensus was defined as 60% or greater of panelists agreeing on the priority category. We then coded research questions using an National Trauma Research Action Plan taxonomy of 118 research concepts, which were consistent across all 11 panels.

RESULTS

Twenty-eight neurotrauma experts generated 675 research questions. Of these, 364 (53.9%) reached consensus, and 56 were determined to be high priority (15.4%), 303 were deemed to be medium priority (83.2%), and 5 were low priority (1.4%). The research topics were stratified into three groups-severe traumatic brain injury (TBI), mild TBI (mTBI), and spinal cord injury. The number of high-priority questions for each subtopic was 46 for severe TBI (19.7%), 3 for mTBI (4.3%) and 7 for SCI (11.7%).

CONCLUSION

This Delphi gap analysis of neurotrauma research identified 56 high-priority research questions. There are clear areas of focus for severe TBI, mTBI, and spinal cord injury that will help guide investigators in future neurotrauma research. Funding agencies should consider these gaps when they prioritize future research.

Outcomes after emergency general surgery and trauma care in incarcerated individuals: an EAST multi-center study

BACKGROUND

The US incarcerates more individuals than any other country. Prisoners are the only population guaranteed health care by the US constitution, but little is known about their surgical needs. This multicenter study aimed to describe the acute care surgery (ACS) needs of incarcerated individuals.

METHODS

Twelve centers prospectively identified incarcerated patients evaluated in their emergency department (ED) by the ACS service. Centers collected diagnosis, treatment, and complications from chart review. Patients were classified as either emergency general surgery (EGS) patients or trauma patients and their characteristics and outcomes were investigated. Poisson regression accounting for clustering by center was used to calculate the relative risk (RR) of readmission, re-presentation within 90 days, and failure to follow up as an outpatient within 90 days for each cohort.

RESULTS

Over 12 months, ACS services evaluated 943 patients, 726 (80.3%) from jail, 156 (17.3%) from prison, and 22 (2.4%) from other facilities. Most were men (89.7%) with a median age of 35 years (IQR 27,47). Trauma patients comprised 54.4% (n = 513) of the cohort. Admission rates were similar for trauma (61.5%) and EGS patients (60.2%). Head injuries and facial fractures were the most common injuries, while infections were the most common EGS diagnosis. Self-harm resulted in 102 trauma evaluations (19.9%). Self-inflicted injuries were associated with increased risk of readmission (RR 4.3, 95%CI: 3.02-6.13) and reevaluation within 90 days (RR 4.96, 95%CI 3.07-8.01).

CONCLUSIONS

Incarcerated patients who present with a range of trauma and EGS conditions frequently require admission, and follow-up after hospitalization was low at the treating center. Poor follow-up coupled with high rates of assault, self-harm, mental health, and substance use disorders highlight the vulnerability of this population. Hospital and correctional facility interventions are needed to decrease self-inflicted injuries and assaults while incarcerated.

Intellectual/developmental disabilities among people incarcerated in federal correctional facilities in Ontario, Canada: Examining prevalence, health and correctional characteristics

BACKGROUND

There is little research with people who experience intellectual/developmental disabilities and imprisonment.

METHODS

The study linked health and correctional data to examine prevalence of intellectual/developmental disabilities and health and correctional characteristics among adults experiencing their first federal incarceration between 1 January 2002 and 31 December 2011 (n = 9278) and two non-incarcerated groups (n = 10,086,802).

RESULTS

The prevalence of intellectual/developmental disabilities was 2.1% in the incarcerated group and 0.9% in the non-incarcerated group. Before incarceration, those with, versus without, intellectual/developmental disabilities were at greater risk of traumatic brain injury, mental illness, and substance use disorders. While incarcerated, those with intellectual/developmental disabilities were more likely to incur serious institutional disciplinary charges. Post-incarceration, persons with intellectual/developmental disabilities were at greater risk of emergency department visits, and psychiatric and acute hospitalizations, than the non-incarcerated groups.

CONCLUSIONS

People with intellectual/developmental disabilities are overrepresented in Canadian federal correctional institutions. The authors offer strategies to support people prior to, during, and post-incarceration.

The prevalence, characteristics, and psychiatric correlates of traumatic brain injury in incarcerated individuals: an examination in two independent samples

PRIMARY OBJECTIVE

Identify the prevalence, characteristics, and psychological correlates of traumatic brain injury (TBI) among incarcerated individuals.

RESEARCH DESIGN

Three aims: (1) Determine the prevalence and characteristics of TBI in 1469 adults incarcerated in Wisconsin state prisons (1064 men, 405 women); (2) Characterize the relationship between mild TBI and mental illness in a sub-sample of men and women; (3) Reproduce the findings from Aim 1 and Aim 2 in an independent sample of 1015 adults incarcerated in New Mexico state prisons (600 men, 415 women).

METHODS AND PROCEDURES

Standardized TBI assessment with structured clinical interviews and self-report questionnaires.

MAIN OUTCOMES AND RESULTS

Rates of TBI were approximately five times greater than the general population, with a substantially higher rate of TBI caused by assault. In the Wisconsin sample, mild TBI was associated with greater levels of post-traumatic stress disorder (PTSD) among women (but not among men). In the New Mexico sample, TBI of any severity was associated with greater levels of major depressive disorder (MDD) among women (but not among men).

CONCLUSIONS

This study thus provides novel data on TBI and its correlates among individuals incarcerated in state prisons, and highlights a specific treatment need within the prison population.

Neurobiology of Female Homicide Perpetrators

Neurobiology of female homicide perpetrators is not well understood. Data from private interviews and examinations of females were re-analyzed comparing those who committed homicide (n = 9); other violent crimes, no known homicide (n = 51); nonviolent crimes, no known violent convictions (n = 49); and noncriminals (n = 12). Homicide perpetrators suffered the most childhood sexual abuse (CSA); most recent abuse; had the most neurological histories, mainly traumatic brain injuries (TBIs); most health care access for abuse-related injuries; lowest AM and PM salivary cortisol; and greatest proportion who committed crime under the influence of alcohol. Only CSA, years since last abuse, TBI, neurological histories, and health care access for abuse-related injuries were significant. Those who committed homicide under the influence of alcohol suffered the most recent abuse and had the lowest AM cortisol and flattest diurnal cortisol slope (DCS) compared with others; though the n precludes determining significance. Amount of time since last abuse, AM cortisol and DCS progressively decreased as crime severity increased; other variables progressively increased as crime severity increased. These preliminary findings suggest that low AM cortisol, flat DCS, greater CSA frequency and severity, recent abuse, TBIs, and health care access for abuse-related injuries could be risk factors for females committing homicide. Further study is needed due to the small n of homicide perpetrators. Abuse victims may be at greater risk for alcohol use and cortisol dysregulation associated with perpetrating violence, especially homicide. Frontal lobe damage from TBIs may decrease ability to control behaviors associated with emotions from the limbic system. Health care providers released these women when their abuse-related injuries were not life-threatening; yet, they were life-threatening for victims of their subsequent homicides. Females accessing health care for abuse-related injuries present a critical opportunity for violent crime prevention interventions.

Strengthening the Connection Between Acquired Brain Injury (ABI) and Family Violence: The Importance of Ongoing Monitoring, Research and Inclusive Terminology

Family violence (FV) harms communities worldwide so FV prevention strategies and effective responses are urgently needed. This article reports on FV apparent in a study which explored the experiences of people with both ABI and justice system encounters in Victoria, Australia. One hundred interviews and one focus group consulted people with ABI, their families and carers, and various stakeholder groups in the Victorian justice system in Australia. Qualitative content analysis determined dominant themes and sub-themes and the less common themes. Inductive interpretive content analysis identified themes commonly found in previous published research and themes that appeared unique to, or unanticipated in, our data, such as the FV theme upon which this article focuses. Our findings reveal that FV has adversely affected many people with ABI who came into contact with Victoria's justice system. Further, as ABI and FV often co-occur with substance abuse, mental health problems, socio-economic and many other significant disadvantages, for some FV perpetrators with an ABI, their ABI symptoms and characteristic co-morbidities may be a mitigating factor in their offending. The connection between ABI and family violence emerged as a troubling research theme. Indeed, the impact of FV on too many of our participants with an ABI compels us to call for further related research and secondary prevention programs targeted at FV victims, and offenders, living with ABI. An intersectional understanding of family violence and TBI/ABI in social ecological contexts is required to better understand brain injury at both individual and population levels.

Executive functioning among first time and recidivist inmates in Uruguay

Previous research has found association between antisocial behavior and deficits in executive functioning. However, research into a link between them accounting for criminal history has found divergent results in western countries. The present study sought to determine the severity of executive functioning deficits in offenders compared to a normative sample, and the differences between first time offenders as compared to recidivists in Uruguay using a cross-sectional design. The neuropsychological performance of 334 male adult inmates was assessed using the BRIEF- A and a normative sample of 377. Results indicated that offenders performed significantly worse than non-offenders in the global score and the subscales of the BRIEF-A. Moreover, first time offenders exhibited less performance deficits in cognitive functioning than recidivist offenders. Compared to first time offenders, recidivist showed executive dysfunction concerning behavioral regulation index and globally. These results enhance our knowledge about executive dysfunction associated with criminality and may help to tailor the offenders' programs to offenders with executive deficits.

Acquired Brain Injury and Interventions in the Offender Population: A Systematic Review

Background and Aims: The prevalence of acquired brain injury (ABI) in offender populations appears much higher than in the general population, being estimated at 50% compared to 12%, respectively. Taking into account ABI-related cognitive and social impairments or behavioral changes in forensic treatments might be relevant and may improve treatment outcomes. The aim of the current review is to summarize and integrate the literature on psychological interventions or treatments for consequences of ABI in the forensic setting. Reviewing this literature could provide crucial information for improving treatment options for offenders with ABI, which may contribute to reducing recidivism. Methods: The PubMed/MEDLINE, PsychInfo, CINAHL, COCHRANE, and Web of Science databases were searched for studies in adult offenders with ABI that evaluated the effect of psychological interventions with a focus on ABI-related impairments and recidivism. Results: This review identified four intervention studies that met the inclusion criteria. These included an adult population (≥18-year-old) in a forensic setting (given the focus of the current review on treatment, defined here as an environment in which offenders are treated while being incarcerated or as outpatients), non-pharmacological treatments and were published in English or Dutch between 2005 and 2020. All studies reported some positive effects of the intervention on interpersonal behavior, cognition and recidivism. The aspects of the interventions that seemed most beneficial included personalized treatment and re-entry plans, support for the individual and their environment and psychoeducation about the effects of ABI. Discussion: Although positive effects were reported in the studies reviewed, all studies had methodological limitations in terms of sample size, study design and outcome measures which affects the strength of the evidence. This limits strong conclusions and generalizability to the entire offender population. Conclusion: Despite high prevalence of ABI in offender populations, interventions in forensic settings seldom address the effect of ABI. The few studies that did take ABI into account reported positive effects, but those results should be interpreted with caution. Future studies are warranted, since this does seem an important venue to improve treatment, which could eventually contribute to reducing recidivism.

A Systematic Review of Quality of Life Assessments of Offenders

Strength-based theories of rehabilitation emphasize the importance of opportunities for offenders to achieve "good lives" to not re-offend. The extent to which these groups feel enabled to achieve a good life may be measured through subjective, overall quality of life (QoL). The aim is to systematically review the QoL instruments used among detained offenders and synthesize the factors related to their QoL. A systematic literature review was conducted to retrieve articles that assessed the overall QoL of a sample of detained offenders using a validated instrument. The instruments' specificity, dimensionality, and respondent and administrator burden were assessed, and factors reported as significantly related to QoL were summarized. In total, 41 articles were included in the review: 20 reported on forensic samples and 20 on prisoners, with one study randomly assigning offenders to either forensic treatment or prison. Among the included articles, 12 validated instruments were utilized. Only one instrument, the Forensic Inpatient Quality of Life Questionnaire, was specifically developed for and validated in forensic patients. Detained offending populations reported lower QoL than the general population, and those with untreated mental illness reported the lowest. The most consistent predictors of QoL longitudinally were social factors, while substance use and detention-specific variables were not consistently related. In general, the relationships between poor mental health, loneliness, and poor QoL seen in offenders are also seen among other marginalized populations. To improve the evidence base for QoL assessment in this vulnerable group, current gold standard QoL instruments should be validated in detained populations.

Pediatric traumatic brain injury and abusive head trauma

Childhood traumatic brain injury (TBI) commonly occurs during brain development and can have direct, immediately observable neurologic, cognitive, and behavioral consequences. However, it can also disrupt subsequent brain development, and long-term outcomes are a combination of preinjury development and abilities, consequences of brain injury, as well as delayed impaired development of skills that were immature at the time of injury. There is a growing number of studies on mild TBI/sport-related concussions, describing initial symptoms and their evolution over time and providing guidelines for effective management of symptoms and return to activity/school/sports. Mild TBI usually does not lead to long-term cognitive or academic consequences, despite reports of behavioral/psychologic issues postinjury. Regarding moderate to severe TBI, injury to the brain is more severe, with evidence of a number of detrimental consequences in various domains. Patients can display neurologic impairments (e.g., motor deficits, signs of cerebellar disorder, posttraumatic epilepsy), medical problems (e.g., endocrine pituitary deficits, sleep-wake abnormalities), or sensory deficits (e.g., visual, olfactory deficits). The most commonly reported deficits are in the cognitive-behavioral field, which tend to be significantly disabling in the long-term, impacting the development of autonomy, socialization and academic achievement, participation, quality of life, and later, independence and ability to enter the workforce (e.g., intellectual deficits, slow processing speed, attention, memory, executive functions deficits, impulsivity, intolerance to frustration). A number of factors influence outcomes following pediatric TBI, including preinjury stage of development and abilities, brain injury severity, age at injury (with younger age at injury most often associated with worse outcomes), and a number of family/environment factors (e.g., parental education and occupation, family functioning, parenting style, warmth and responsiveness, access to rehabilitation and care). Interventions should identify and target these specific factors, given their major role in postinjury outcomes. Abusive head trauma (AHT) occurs in very young children (most often <6 months) and is a form of severe TBI, usually associated with delay before appropriate care is sought. Outcomes are systematically worse following AHT than following accidental TBI, even when controlling for age at injury and injury severity. Children with moderate to severe TBI and AHT usually require specific, coordinated, multidisciplinary, and long-term rehabilitation interventions and school adaptations, until transition to adult services. Interventions should be patient- and family-centered, focusing on specific goals, comprising education about TBI, and promoting optimal parenting, communication, and collaborative problem-solving.

Examining the Efficacy of Communication Partner Training for Improving Communication Interactions and Outcomes for Individuals With Traumatic Brain Injury: A Systematic Review

OBJECTIVE

To describe the evidence regarding communication partner training (CPT) interventions for individuals with traumatic brain injury (TBI) and their conversation partners.

DATA SOURCES

Eleven key databases-PubMed, CINAHL, Cochrane Registry of Controlled Trials, Embase, Linguistic and Language Behavior Abstracts, ProQuest, Scopus, Web of Science, PsycBITE, SpeechBITE, and ERIC-were searched from inception through 2019.

STUDY SELECTION

Selected articles had to be peer reviewed, written in English, experimental or quasiexperimental design, report on TBI communication partners, and describe interventions or strategies targeting communication partners.

DATA EXTRACTION

Of 1088 articles identified, 12 studies were selected for data extraction, critical appraisal, and analysis with considerations of sex and gender. The Oxford Centre for Evidence-Based Medicine's guideline was used to critically appraise Levels of Evidence. Assessment of bias was conducted using the Cochrane Collaboration tools for randomized controlled trials and risk of bias in nonrandomized studies of interventions for nonrandomized controlled trials and the risk of bias in N-of-1 trials scale.

DATA SYNTHESIS

A systematic review with a qualitative meta-analysis of themes and findings across the selected studies identified 3 major categories: (1) benefits of the training for those with TBI, (2) risks of CPT, and (3) suggestions to improve its efficacy.

CONCLUSION

Most of the evidence comes from 1 research group, which may be viewed as a weakness in the current body of literature. However, although the evidence to date is modest, CPT may help to increase accessibility and reduce participation inequities in the community for individuals with TBI.

A scoping review of military veterans involved in the criminal justice system and their health and healthcare

BACKGROUND

In the criminal justice system, special populations, such as older adults or patients with infectious diseases, have been identified as particularly vulnerable to poor health outcomes. Military veterans involved in the criminal justice system are also a vulnerable population warranting attention because of their unique healthcare needs. This review aims to provide an overview of existing literature on justice-involved veterans' health and healthcare to identify research gaps and inform policy and practice.

METHODS

A systematic search was conducted to identify research articles related to justice-involved veterans' health and healthcare that were published prior to December 2017. Study characteristics including healthcare category, study design, sample size, and funding source were extracted and summarized with the aim of providing an overview of extant literature.

RESULTS

The search strategy initially identified 1830 unique abstracts with 1387 abstracts then excluded. Full-text review of 443 articles was conducted with 252 excluded. There were 191 articles included, most related to veterans' mental health (130/191, 68%) or homelessness (24/191, 13%). Most studies used an observational design (173/191, 91%).

CONCLUSIONS

Knowledge gaps identified from the review provide guidance on future areas of research. Studies on different sociodemographic groups, medical conditions, and the management of multiple conditions and psychosocial challenges are needed. Developing and testing interventions, especially randomized trials, to address justice-involved veterans care needs will help to improve their health and healthcare. Finally, an integrated conceptual framework that draws from diverse disciplines, such as criminology, health services, psychology, and implementation science is needed to inform research, policy and practice focused on justice-involved veterans.

Examining Employment Outcomes of Offender and Nonoffender Vocational Program Graduates

Researchers have found providing employment opportunities for ex-offenders through job training programs to be effective at reducing recidivism. Examining various community-based programs for ex-offenders can be beneficial as they may be able to provide more stable and consistent programming without relying on the justice system. This study examined employment outcomes of graduates with and without criminal histories ( n = 617) from a community-based vocational training program. Results showed that ex-offender graduates obtained employment at equal rates to nonoffender graduates and received equal pay to their nonoffender counterparts. This could indicate that for the vocationally educated ex-offender, employment outcomes may be able to equal those of other job-searching individuals with similar backgrounds but without a criminal history. Community-based programs for ex-offenders may be able to provide effective programming to improve vocational attainment within this group, thereby potentially easing the burden on criminal justice institutions as the sole provider of offender rehabilitation.

The associations of poor psychiatric well-being among incarcerated men with injecting drug use histories in Victoria, Australia

BACKGROUND

Dual substance dependence and psychiatric and psychological morbidities are overrepresented in prison populations and associated with reoffending. In the context of an increasing prison population in Australia, investigating the needs of vulnerable people in prison with a dual diagnosis can help inform in-prison screening and treatment and improve prison and community service integration and continuation of care. In this study we quantified psychiatric well-being in a sample of people in prison with a history of injecting drug use in Victoria, Australia, and identified factors associated with this outcome.

METHODS AND RESULTS

Data for this paper come from baseline interviews undertaken in the weeks prior to release as part of a prospective cohort study of incarcerated men who reported regular injecting drug use prior to their current sentence. Eligible participants completed a researcher-administered structured questionnaire that canvassed a range of issues. Psychiatric well-being was assessed using the 12-item General Health Questionnaire (GHQ-12) and potential correlates were included based on a review of the literature. Of the 317 men included for analyses, 139 were classified as experiencing current poor psychiatric well-being. In the multivariate model using modified logistic regression, history of suicide attempt (aOR = 1.36, 95%CI 1.03-1.78), two or more medical conditions (aOR = 1.87, 95%CI 1.30-2.67) and use of crystal methamphetamine in the week prior to their current sentence (aOR = 1.52, 95%CI 1.05-2.22) were statistically significantly associated with current poor psychiatric well-being.

CONCLUSIONS

Comprehensively addressing the health-related needs for this vulnerable population will require a multidisciplinary approach and enhancing opportunities to screen and triage people in prison for mental health and other potential co-occurring health issues will provide opportunities to better address individual health needs and reoffending risk.

Wake-promoting effects of vagus nerve stimulation after traumatic brain injury: upregulation of orexin-A and orexin receptor type 1 expression in the prefrontal cortex

Orexins, produced in the lateral hypothalamus, are important neuropeptides that participate in the sleep/wake cycle, and their expression coincides with the projection area of the vagus nerve in the brain. Vagus nerve stimulation has been shown to decrease the amounts of daytime sleep and rapid eye movement in epilepsy patients with traumatic brain injury. In the present study, we investigated whether vagus nerve stimulation promotes wakefulness and affects orexin expression. A rat model of traumatic brain injury was established using the free fall drop method. In the stimulated group, rats with traumatic brain injury received vagus nerve stimulation (frequency, 30 Hz; current, 1.0 mA; pulse width, 0.5 ms; total stimulation time, 15 minutes). In the antagonist group, rats with traumatic brain injury were intracerebroventricularly injected with the orexin receptor type 1 (OX1R) antagonist SB334867 and received vagus nerve stimulation. Changes in consciousness were observed after stimulation in each group. Enzyme-linked immunosorbent assay, western blot assay and immunohistochemistry were used to assess the levels of orexin-A and OX1R expression in the prefrontal cortex. In the stimulated group, consciousness was substantially improved, orexin-A protein expression gradually increased within 24 hours after injury and OX1R expression reached a peak at 12 hours, compared with rats subjected to traumatic brain injury only. In the antagonist group, the wake-promoting effect of vagus nerve stimulation was diminished, and orexin-A and OX1R expression were decreased, compared with that of the stimulated group. Taken together, our findings suggest that vagus nerve stimulation promotes the recovery of consciousness in comatose rats after traumatic brain injury. The upregulation of orexin-A and OX1R expression in the prefrontal cortex might be involved in the wake-promoting effects of vagus nerve stimulation.
