Individual psychological factors have been shown to exacerbate risk for posttraumatic stress disorder (PTSD) symptoms in youth following maltreatment, but the novel contribution of the present study includes a focus on interactive relationships between these factors on specific PTSD symptom clusters. This study identified maltreated youth at highest risk for re-experiencing, avoidance, and hyperarousal symptom clusters via cognitive, affective, and demographic variables. Participants (n=400) included ethnically diverse maltreated youth...

Peritraumatic dissociation, a term used to describe a complex array of reactions to trauma, including depersonalization, derealization, and emotional numbness, has been associated with posttraumatic stress disorder (PTSD) symptoms across a number of studies. Cognitive theory suggests that interpretations of traumatic events and reactions underlie the persistence of PTSD. The present study examined the associations among peritraumatic dissociation, posttraumatic cognitions, and PTSD symptoms in a group of trauma-exposed adults (N = 169)...

All modern clinical studies using the classic hallucinogen lysergic acid diethylamide (LSD) in healthy subjects or patients in the last 25 years are reviewed herein. There were five recent studies in healthy participants and one in patients. In a controlled setting, LSD acutely induced bliss, audiovisual synesthesia, altered meaning of perceptions, derealization, depersonalization, and mystical experiences. These subjective effects of LSD were mediated by the 5-HT2A receptor. LSD increased feelings of closeness to others, openness, trust, and suggestibility...

BACKGROUND: Anxiety sensitivity cognitive concerns (ASCC), refer to fears of mental catastrophe or losing control over mental processes. Recent findings show that ASCC are related to suicide risk, mood disorders and trauma-related disorders. Using controlled experimental psychopathology paradigms could be one heretofore unutilized method of increasing understanding of ASCC. Our goal was to test fear reactivity to four head-mounted display perceptual illusion challenges designed to bring on feelings of cognitive dyscontrol (i...

OBJECTIVES: Healthcare professionals (HCPs) with opioid dependence are at risk for relapse and death, particularly in the first year of recovery; however, maintenance treatment with opioid agonists is controversial in this safety-sensitive group. We evaluated long-term safety, tolerability, and treatment outcomes of injectable, intramuscular, extended-release naltrexone (XR-NTX) in opioid-dependent HCPs. METHODS: This single-arm, multisite, open-label study was conducted in opioid-dependent HCPs who had been detoxified from opioids for at least 2 weeks...

This study inquires into neurobiological response to stress and its clinical correlates among adolescents with post-traumatic stress disorder (PTSD). Structural magnetic resonance imaging (MRI) measures of cerebral anatomy were carried out on 23 female adolescents with PTSD related to severe childhood sexual abuse and 21 matched healthy controls. Clinician Administered PTSD Scale for Children and Adolescents, Adolescent Dissociative Experiences Scale, Childhood Trauma Questionnaire, Schedule for Affective Disorders and Schizophrenia for School Age Children, Beck Depression Scale, and a set of neuro-cognitive tests were administered to all participants...

BACKGROUND: Anomalous self-experiences (ASEs), presumably involving alterations in "core" or "minimal self," have been studied as manifest in schizophrenia and its spectrum, in contrast with mood disorder and personality disorder samples. This is the first study to examine ASEs in panic disorder (PD), beginning the exploration of these disturbances of subjectivity in anxiety disorders. We aimed to clarify what might, or might not, be specific to the schizophrenia spectrum domain - which, in turn, could be useful for developing pathogenetic models for various disorders...

To address the symptoms of depersonalization and derealization a specific dissociative subtype of posttraumatic stress disorder has been included in DSM-5. Depersonalization and derealization have been defined as acute and chronic symptoms of dissociative disorders since DSM-III. Dissociative disorders with chronic features are often diagnosed in North America, Canada and other European countries, but this is not the case in Argentina. Dissociative disorders have clinical and historical features that are strongly connected with hysteria...

BACKGROUND: The dissociative PTSD (D-PTSD) subtype was first introduced into the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) in 2013. Prior to this, studies using latent profile analysis (LPA) or latent class analysis (LCA), began to provide support for the D-PTSD construct and associated risk factors. This research is important, because dissociative symptoms in the context of PTSD may potentially interfere with treatment course or outcome. The aims of the present study were twofold: to systematically review the LCA and LPA studies investigating support for the D-PTSD construct; and to review the associated research on the risk factors or covariates of D-PTSD in the identified studies...

Dissociation involves disruptions of usually integrated functions of consciousness, perception, memory, identity, and affect (e.g., depersonalization, derealization, numbing, amnesia, and analgesia). While the precise neurobiological underpinnings of dissociation remain elusive, neuroimaging studies in disorders, characterized by high dissociation (e.g., depersonalization/derealization disorder (DDD), dissociative identity disorder (DID), dissociative subtype of posttraumatic stress disorder (D-PTSD)), have provided valuable insight into brain alterations possibly underlying dissociation...

REVIEW
Louis Sass, Matthew Ratcliffe
"Atmospheric" alterations are key aspects of altered subjectivity in mental disorder. Karl Jaspers famously described the "delusional mood": a sense of uncanny salience and ominousness that often precedes the onset of schizophrenic psychosis or of delusions. Such experiences, he writes, involve "a transformation in our total awareness of reality" that often verges on ineffability. In psychiatry, these experiential alterations are often referred to in terms of "derealization." Though derealization most obviously refers to a decline in the sense of objective presence or felt actuality, it can also refer to other unusual experiences in which things seem unlike normal or standard reality, including altered familiarity, vitality, meaning, or relevance...

BACKGROUND: This study aimed to extend the current understanding of dissociative symptoms experienced by patients with dissociative (psychogenic, non-epileptic) seizures (DS), including psychological and somatoform types of symptomatology. An additional aim was to assess possible relationships between dissociation, traumatic experiences, post-traumatic symptoms and seizure manifestations in this group. METHOD: A total of 40 patients with DS were compared with a healthy control group (n = 43), matched on relevant demographic characteristics...

BACKGROUND: Posttraumatic stress disorder (PTSD) is associated with hyperarousal and active fight or flight defensive responses. By contrast, the dissociative subtype of PTSD, characterized by depersonalization and derealization symptoms, is frequently accompanied by additional passive or submissive defensive responses associated with autonomic blunting. Here, the periaqueductal gray (PAG) plays a central role in defensive responses, where the dorsolateral (DL-PAG) and ventrolateral PAG (VL-PAG) are thought to mediate active and passive defensive responses, respectively...

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...

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...

Depersonalization (DEP) and derealization (DER) were examined among college students with and without borderline personality disorder (BPD) and/or dissociative disorders (DDs) by self-report and clinician assessment. The Steinberg Depersonalization Questionnaire (SDEPQ), the Steinberg Derealization Questionnaire (SDERQ), the Childhood Trauma Questionnaire, and the screening tool of the BPD section of the Structured Clinical Interview for DSM-IV (SCID-BPD) were administered to 1,301 students. Those with BPD (n = 80) according to the SCID-BPD and 111 non-BPD controls were evaluated using the Structured Clinical Interview for DSM-IV Dissociative Disorders by a psychiatrist blind to the diagnosis...

This study examined in real time the role of sleep and daydreaming as potentiating states for subsequent dissociation in depersonalization/derealization disorder (DDD). Research and theory suggests that dissociation may be exacerbated and maintained by a labile sleep-wake cycle in which "dream-like" mentation intrudes into waking life and fuels dissociative symptoms. We explore and extend this idea by examining the state of daydreaming in dissociation. Daydreaming is a state of consciousness between dreaming and waking cognition that involves stimulus-independent and task-unrelated mentation...
