This special issue on psychiatric/psychological injury and law covers major developments in the field, and illustrates the complexities for mental health professionals in dealing with psychiatric/psychological injuries in court. The articles vary in the range of topics covered, and include ones on posttraumatic stress disorder, other trauma reactions, dissociation, disability, pain, and traumatic brain injury, in particular but also new areas, such as the effects of early penile injury. Work in the area of psychiatric/psychological injury and law needs to be scientifically-informed, comprehensive, and impartial, and the series of articles to follow will help workers in the area meet this standard...

Defense reactions to threatening situations are vital adaptations to stress that protect organisms from injury and ensure survival. We retrospectively investigated the role of peritraumatic dissociation (PD) in the occurrence of severe psychopathology and dissociative patterns of reactions in borderline personality disorder (BPD). We recruited 28 patients with a clinical diagnosis of BPD and 15 healthy controls. The BPD group was divided according to the level of PD (low vs. high): BPD and PD (n = 15) and BPD only (n = 13)...

: Mitochondria play a variety of functional roles in cortical neurons, from metabolic support and neuroprotection to the release of cytokines that trigger apoptosis. In dendrites, mitochondrial structure is closely linked to their function, and fragmentation (fission) of the normally elongated mitochondria indicates loss of their function under such pathological conditions as stroke and brain trauma. Using in vivo two-photon microscopy in mouse brain, we quantified mitochondrial fragmentation in a full spectrum of cortical injuries ranging from severe to mild...

BACKGROUND: Despite empirical evidence suggesting complex associations between childhood trauma and self-harm, there is a dearth of research investigating this association in the female prison population. The current study explored pathways to self-harm following childhood trauma, by investigating the mediating roles of Post-traumatic Stress Disorder (PTSD) symptoms, emotion regulation and dissociation, in this relationship, within a sample of 89 female prisoners. METHODS: Cross-sectional, interview-format, questionnaire study within a female prison population...

BACKGROUND: Early traumatic experiences are thought to be causal factors in the development of trauma-related dissociative experiences, including depersonalization and derealization. The rubber hand illusion (RHI), a well-known paradigm that measures multi-sensorial integration of a rubber hand into one's own body representation, has been used to investigate alterations in the experience of body ownership and of body representation. Critically, however, it has never been studied in individuals with trauma-related disorders...

BACKGROUND AND OBJECTIVES: Although previous studies showed that thought and emotion suppression represent risk factors for intrusions development, the mechanisms that explain these relations were less explored. This study aims to examine the relationships between thought and emotion suppression and the symptoms of intrusion following the exposure to a trauma-related event. Moreover, we explored if these relationships would be mediated by peritraumatic state dissociation and state anxiety...

The first part of the series of three articles on posttraumatic stress disorder (PTSD) in Court to appear in the journal reviews the history of the construct of PTSD and its presentation in the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition; American Psychiatric Association, 2013) and the ICD-11 (International Classification of Diseases, 11th Edition; World Health Organization, 2018). There are 20 symptoms of PTSD in the DSM-5. PTSD symptoms are arranged into a four-cluster model, which has received partial support in the literature...

BACKGROUND: Ketamine has been well studied for its efficacy as an analgesic agent. However, intranasal (IN) administration of ketamine has only recently been studied in the emergency setting. The objective of this study was to elucidate the efficacy and adverse effects of a sub-dissociative dose of IN Ketamine compared to IV and IM morphine. METHODS: A single-center, randomized, prospective, parallel clinical trial of efficacy and safety of IN ketamine compared to IV and IM morphine for analgesia in the emergency department (ED)...

BACKGROUND: Psychopathy is a specific syndrome that predicts future violent and aggressive behavior in adults. Studies in youth and adults have demonstrated a strong association between early traumatic incidents and later dissocial behavior. Moreover, the impact of personality pathology and emotional dysregulation on aggressive and violent behavior is well established. However, few studies have addressed the relationship between early traumatization and psychopathic traits in adolescents...

The neuroimaging literature provides compelling evidence for functional dysconnectivity in people with psychosis. However, it is likely that at least some of the observed alterations represent secondary effects of illness chronicity and/or antipsychotic medication. In addition, the extent to which these alterations are specific to psychosis or represent a transdiagnostic feature of psychiatric illness remains unclear. The aim of this study was therefore to examine the diagnostic specificity of functional dysconnectivity in drug-naïve first-episode psychosis (FEP)...

This study aims to investigate the prevalence of deliberate self-harm and its relationships to childhood and recent trauma and different patterns of dissociative features. A total of 100 male and 100 female college students were administered a 58-item questionnaire designed to detect the extent of dissociation, deliberate self-harm, and trauma history. Participants with deliberate self-harm behaviors reported more traumatic experiences and dissociative features than participants without such behaviors. Furthermore, the prevalence of deliberate self-harm (i...

Objective: Research with partner-violent men has found that a subset of this population reports dissociative experiences during their violence (e.g., inability to remember violence [despite admission that it had occurred]; flashbacks during violence). However, the literature examining this phenomenon has been primarily limited to clinical observations and case studies, and there is a need for more thorough empirical investigation regarding the prevalence and correlates of dissociative violence among individuals in intimate partner violence (IPV) intervention programs...

Childhood sexual abuse (CSA) is an extreme traumatic event associated with numerous long lasting difficulties and symptoms (e.g., Herman, 1992). These include, among other things, the impediment of basic interpersonal structures of attachment (Rumstein-McKean & Hunsley, 2001), as well as impairment of mental integration manifested in dissociation (Van Den Bosch et al., 2003). Theoretically, attachment insecurities and dissociation are closely linked, since dissociation is generated as a way to resolve the conflicted attachment demands faced by the abused child (e...

A history of traumatic brain injury (TBI) is linked to an increased risk for the later development of dementia. This encompasses a variety of neurodegenerative diseases including Alzheimer's Disease (AD) and chronic traumatic encephalopathy (CTE), with AD linked to history of moderate-severe TBI and CTE to a history of repeated concussion. Of note, both AD and CTE are characterized by the abnormal accumulation of hyperphosphorylated tau aggregates, which are thought to play an important role in the development of neurodegeneration...

INTRODUCTION: Complicated grief (CG) has been the subject of increasing attention in the past decades but its relationship with separation anxiety disorder (SEPAD) is still controversial. The aim of the current study was to explore the prevalence and clinical significance of adult SEPAD in a sample of help-seeking individuals with CG. METHODS: 151 adults with CG, enrolled in a randomized controlled trial comparing the effectiveness of (CG) treatment to that of interpersonal therapy, were assessed by means of the Inventory of Complicated Grief (ICG), the Structured Clinical Interview for DSM-IV, the Hamilton Rating Scale for Depression (HAM-D), the Work and Social Adjustment Scale (WSAS), the Adult Separation Anxiety Questionnaire (ASA-27), the Grief Related Avoidance Questionnaire (GRAQ), the Peritraumatic Dissociative Experiences Questionnaire (PDEQ), and the Impact of Events Scale (IES)...

Several authors have studied dissociation within the borderline personality disorder (BPD) population and postulated 3 dissociative subgroups. Conversely, other authors suggest that dissociation may play a central role in the development of trauma-related disorders and specifically in BPD. Nevertheless, the role of dissociation in BPD seems to be controversial. Our aim is to perform a meta-analytic review of the literature to evaluate the extent of dissociation in BPD compared to other psychopathological disorders to clarify its role in this specific condition...

According to recent findings stressful experiences may influence various physiological disturbances and also neuroanatomical changes and some studies also show that psychotherapy and meditation may influence brain functions. Traumatic stress is frequently related to a dissociative response that disintegrates conscious experience. In this context, self-reflection is an essential principle in the process of posttraumatic growth related to spiritual experiences and meditation states that enable mental integration and create the novel integrated self...

Controversy exists regarding the merits of exposure-based treatments for posttraumatic stress disorder (PTSD) versus a phased approach when prominent dissociative symptoms are present. The first aim of this study was to examine the degree to which diagnosing dissociation in two traumatized patients' vignettes influenced clinicians' preference for phase-oriented treatment and whether clinicians' treatment experience contributed to their treatment preference. The second aim was to assess the extent to which participants had observed traumatized patients worsen when treated with exposure therapy or phase-oriented therapy and whether the theoretical orientation and treatment experience of the clinician were related to the observed deterioration...

Traumatic brain injury (TBI)-induced agitation and aggression pose major obstacles to clinicians in the acute hospital and rehabilitation settings. Thus, management of these symptoms is crucial. Antipsychotic drugs (APDs) are a common treatment approach for alleviating these symptoms. However, previous preclinical TBI studies have indicated that daily and chronic administration of these drugs (e.g., haloperidol; HAL) can exacerbate cognitive and motor deficits. Quetiapine (QUE) is an atypical APD that differs from many typical APDs, such as HAL, in its relatively rapid dissociation from the D2 receptor...

Elevations on certain Conners' CPT-II scales are known to be associated with invalid responding. However, scales and cutoffs vary across studies. In addition, the methodology behind developing performance validity tests (PVTs) has been challenged for mistaking true impairment for noncredible presentation. Using ability-based tests as a PVT makes clinicians especially vulnerable to this criticism. The present study examined the ability of CPT-II to dissociate effort from impairment in 47 adults clinically referred for neuropsychological assessment...
