RESUMEN
Negative symptoms of schizophrenia remain clinically and theoretically understudied and represent an unmet psychiatric need. Negative symptoms are assumed to be related to other psychiatric disorders, but their association with dissociative symptoms is yet to be explored, particularly in light of depression and anxiety symptoms. We examined the five domains of negative symptoms (anhedonia, asociality, avolition, blunted affect and alogia) in an Israeli national sample of 1930 participants of whom 645 (33.4%) were with increased risk for dissociative disorder. The results show that anhedonia, blunted affect and alogia significantly associated with risk for dissociative disorder, above and beyond depression and anxiety. When assessing for negative symptoms it may be worth screening for dissociation and vice versa and thus make a more accurate clinical picture of the interplay between them.

Dissociation and diminished sense of agency are experiential distortions of disintegration in the perception of self and action. Although one is often implied in the other, they are seldom studied together. Assessing their relationship and shared influences may allow for a more comprehensive and nuanced understanding of dissociative experiences. We aimed to examine their temporal (concurrent or directional) co-occurrence, and to elucidate their etiology, focusing on posttraumatic symptoms (PTS), poor sleep, and their hypothesized joint effect. N = 113 adults oversampled for the existence of trauma exposure history reported PTS and then, for a week, wore an actigraphic sleep monitor, reported subjective sleep quality each morning, and reported state dissociation (depersonalization, derealization, and absorption) and sense of agency four times each day. Data were analyzed using multilevel linear modeling. Higher state dissociation correlated with diminished state sense of agency, but only contemporaneously, not directionally. Both hypothesized etiological factors, namely, PTS (especially complex) and poor sleep (objective and subjective) predicted state dissociation and diminished state sense of agency, but psychological distress seemed to overshadow these main effects. However, robust interactive effects suggested that poor sleep predicted dissociation and disruptions in the sense of agency only among individuals with low PTS. These findings suggest that PTS and poor sleep quality are separate paths to dissociation and impaired sense of agency. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

OBJECTIVE: Dysfunctional cognitions play a central role in the development of post-traumatic stress disorder (PTSD). However the role of specific dissociation-related beliefs about memory has not been previously investigated. This study aimed to investigate the role of dissociation-related beliefs about memory in trauma-focused treatment. It was hypothesized that patients with the dissociative subtype of PTSD would show higher levels of dissociation-related beliefs, dissociation-related beliefs about memory would decrease after trauma-focused treatment, and higher pre-treatment dissociation-related beliefs would be associated with fewer changes in PTSD symptoms. METHOD: Post-traumatic symptoms, dissociative symptoms, and dissociation-related beliefs about memory were assessed in a sample of patients diagnosed with PTSD (n = 111) or the dissociative subtype of PTSD (n = 61). They underwent intensive trauma-focused treatment consisting of four or eight consecutive treatment days. On each treatment day, patients received 90â min of individual prolonged exposure (PE) in the morning and 90â min of individual eye movement desensitization and reprocessing (EMDR) therapy in the afternoon. The relationship between dissociation-related beliefs about memory and the effects of trauma-focused treatment was investigated. RESULTS: Dissociation-related beliefs about memory were significantly associated with PTSD and its dissociative symptoms. In addition, consistent with our hypothesis, patients with the dissociative subtype of PTSD scored significantly higher on dissociation-related beliefs about memory pre-treatment than those without the dissociative subtype. Additionally, the severity of these beliefs decreased significantly after trauma-related treatment. Contrary to our hypothesis, elevated dissociation-related beliefs did not negatively influence treatment outcome. CONCLUSION: The results of the current study suggest that dissociation-related beliefs do not influence the outcome of trauma-focused treatment, and that trauma-focused treatment does not need to be altered specifically for patients experiencing more dissociation-related beliefs about memory because these beliefs decrease in association with treatment.
This study investigated the role of dissociation-related beliefs about memory on trauma-focused treatment.Dissociation-related beliefs were related to post-traumatic and dissociative symptoms, and were especially prominent in patients with the dissociative subtype of post-traumatic stress disorder.Dissociation-related beliefs about memory do not impact the effectiveness of trauma-focused treatment. In fact, trauma-focused treatment effectively decreased these beliefs, suggesting that dissociation-related beliefs about memory should not be a determining factor in withholding patients from receiving trauma-focused therapy.

BACKGROUND: Dissociative experiences commonly occur in schizophrenia spectrum disorders (SSD). Yet little is known about how dissociative experiences in SSD are related to SSD symptoms. Accordingly, we investigated the relations between dissociative experiences and SSD symptoms, focusing on symptoms bridging these 2 symptom clusters as well as their relation to reported trauma history. STUDY DESIGN: Network analyses were conducted on the responses of 248 individuals with an SSD who enrolled from multiple mental health centers in The Netherlands. Dissociative experiences were assessed via the Dissociative Experience Scale, SSD symptoms using the Positive and Negative Syndrome Scale, and trauma history through the Trauma History Questionnaire. STUDY RESULTS: The results indicated that dissociative symptoms in SSD are mostly independent of other symptoms, but that emotional distress bridges between the dissociative and SSD symptom clusters. Furthermore, results revealed associations between positive and negative SSD symptoms and trauma through emotional distress, whereas dissociative symptoms remained relatively isolated. CONCLUSION: Because SSD symptoms and dissociative experiences clustered relatively independent from each other, our findings promote the idea of tailored treatment approaches for individuals with an SSD with frequent dissociative experiences, specifically targeting these symptoms.

INTRODUCTION: Subjective cognitive deficits have been broadly reported in schizophrenia and described by Huber as basic symptoms. It remains unclear however to what extent they may be related to psychosocial stressors including trauma. METHODS: We assessed basic symptoms using the Frankfurt Complaint Questionnaire (FCQ) in a sample of 40 patients with schizophrenia. Trauma-related symptoms were assessed concurrently using the Trauma Symptom Checklist-40, symptoms of dissociation using the Dissociative Experiences Scale, and sensitization phenomena using the Complex Partial Seizure-like Symptoms Inventory and Limbic System Checklist-33. Psychotic symptoms were measured by Health of the Nation Outcome Scales. The dosage of antipsychotic medication was assessed in terms of equivalents of chlorpromazine, and antidepressant medication in terms of equivalents of fluoxetine. Spearman correlations were performed to explore the relationship between FCQ and other trauma-related measures. To determine the relative contributions of trauma-related symptoms to basic symptoms a linear regression analysis was performed. RESULTS: The results showed that higher levels of basic symptoms of schizophrenia were associated with greater levels of symptoms of dissociation, traumatic stress, and sensitization or kindling-like processes in schizophrenia. Among the trauma-related variables, sensitization phenomena assessed with Complex Partial Seizure-like Symptoms Inventory were closely associated with basic symptoms. DISCUSSION: These results indicate that basic symptoms measured by FCQ might be related to trauma. The potential of trauma to influence neurodevelopmental hypotheses of schizophrenia is discussed.

Background: The effect of dissociation and parenting style on the relationship between psychological trauma and psychotic symptoms has not previously been investigated. Objective: The aim of this study was to develop a moderated mediation model to assess whether the association between psychological trauma and psychotic symptoms is mediated by dissociation and moderated by parental maltreatment. Methods: Inpatients with major depressive disorder (MDD) and bipolar depression (BP) were recruited. Self-reported and clinical rating scales were used to measure the level of dissociation, psychotic symptoms, history of psychological trauma and parental maltreatment. The PROCESS macro in SPSS was used to estimate path coefficients and adequacy of the moderated mediation model. High betrayal trauma (HBT), low betrayal trauma (LBT), paternal maltreatment, and maternal maltreatment were alternatively entered into the conceptual model to test the adequacy. Results: A total of 91 patients (59 with MDD and 32 with BP) were recruited, with a mean age of 40.59 ± 7.5 years. After testing with different variables, the moderated mediation model showed that the association between LBT and psychotic symptoms was mediated by dissociation and moderated by maternal maltreatment. A higher level of maternal maltreatment enhanced the effect of LBT on dissociation. Conclusions: Healthcare workers should be aware of the risk of developing psychotic symptoms among depressive patients with a history of LBT and maternal maltreatment.
Antecedentes: El efecto de disociación y el estilo parental en la relación entre el trauma psicológico y los síntomas psicóticos no se han investigado previamente.Objetivo: El objetivo de este estudio fue desarrollar un modelo de mediación moderada para evaluar si la asociación entre trauma psicológico y síntomas psicóticos es mediada por la disociación y moderada por el maltrato de los padres.Métodos: Fueron reclutados pacientes hospitalizados con trastorno depresivo mayor (TDM) y depresión bipolar (DB). Se utilizaron escalas clínicas y de auto-reporte para medir el nivel de disociación, síntomas psicóticos, antecedentes de trauma psicológico y maltrato de los padres. La macro PROCESS en SPSS se utilizó para estimar los coeficientes de ruta y adecuación del modelo de mediación moderada. Alto exposición al trauma de traición (HET), baja exposición al trauma de traición (BET), maltrato paterno y maltrato materno fueron alternativamente ingresados en el modelo conceptual para probar la adecuación.Resultados: Se reclutaron un total de 91 pacientes (59 con TDM y 32 con DB), con una edad media de 40,59 ± 7,5 años. Después de probar con diferentes variables, el modelo moderado de mediación mostró que la asociación entre BET y síntomas psicóticos estuvo mediada por la disociación y moderada por el maltrato materno. Un nivel superior del maltrato materno aumentó el efecto de BET sobre la disociación.Conclusiones: Los trabajadores del área de la salud deben ser conscientes del riesgo del desarrollo de síntomas psicóticos entre los pacientes depresivos con antecedentes de BET y maltrato materno.

BACKGROUND: Suicide attempt is the most predictive risk factor of suicide. Trauma - especially sexual abuse - is a risk factor for suicide attempt and suicide. A common reaction to sexual abuse is dissociation. Higher levels of dissociation are linked to self-harm, suicide ideation, and suicide attempt, but the role of dissociation in suicidal behavior is unclear. METHODS: In this naturalistic study, ninety-seven acute psychiatric patients with suicidal ideation, of whom 32 had experienced sexual abuse, were included. Suicidal behaviour was assessed with The Columbia suicide history form (CSHF). The Brief trauma questionnaire (BTQ) was used to identify sexual abuse. Dissociative symptoms were assessed with Dissociative experiences scale (DES). RESULTS: Patients who had experienced sexual abuse reported higher levels of dissociation and were younger at onset of suicidal thoughts, more likely to self-harm, and more likely to have attempted suicide; and they had made more suicide attempts. Mediation analysis found dissociative experiences to significantly mediate a substantive proportion of the relationship between sexual abuse and number of suicide attempts (indirect effects = 0.17, 95% CI = 0.05, 0.28, proportion mediated = 68%). Dissociative experiences significantly mediated the role of sexual abuse as a predictor of being in the patient group with more than four suicide attempts (indirect effects = 0.11, 95% CI = 0.02, 0.19, proportion mediated = 34%). CONCLUSION: The results illustrate the importance of assessment and treatment of sexual abuse and trauma-related symptoms such as dissociation in suicide prevention. Dissociation can be a contributing factor to why some people act on their suicidal thoughts.

Co-occurrence of mental disorders including severe PTSD, somatic symptoms, and dissociation in the aftermath of trauma is common and sometimes associated with poor treatment outcomes. However, the interrelationships between these conditions at symptom level are not well understood. In the present study, we aimed to explore direct connections between PTSD, somatic symptoms, and dissociation to gain a deeper insight into the pathological processes underlying their comorbidity that can inform future treatment plans. In a sample of 655 adult inpatients with a diagnosis of severe PTSD following childhood abuse (85.6% female; mean age = 47.57), we assessed symptoms of PTSD, somatization, and dissociation. We analyzed the comorbidity structure using a partial correlation network with regularization. Mostly positive associations between symptoms characterized the network structure. Muscle or joint pain was among the most central symptoms. Physiological reactivation was central in the full network and together with concentrations problems acted as bridge between symptoms of PTSD and somatic symptoms. Headaches connected somatic symptoms with others and derealization connected dissociative symptoms with others in the network. Exposure to traumatic events has a severe and detrimental effect on mental and physical health and these consequences worsen each other trans-diagnostically on a symptom level. Strong connections between physiological reactivation and pain with other symptoms could inform treatment target prioritization. We recommend a dynamic, modular approach to treatment that should combine evidence-based interventions for PTSD and comorbid conditions which is informed by symptom prominence, readiness to address these symptoms and preference.

Previous research has shown that emotions can alter our sense of ownership. Whether this relationship is modulated by differences in emotion experience and awareness, however, remains unclear. We investigated this by comparing the susceptibility to the rubber hand illusion (RHI) between participants who were either exposed to a low-arousing emotion induction (sadness) or placed in a neutral control group. Several factors that might influence this relationship were considered: dissociative symptoms were included to observe if a sadness induction led to a higher RHI score in participants scoring high in dissociation, as a result of detached emotion experience. Whether the level of awareness of the emotion mattered was also tested, as subliminal processing was shown to require less focal attention. Therefore, our sample (N = 122) was divided into three experimental groups: Sad pictures were presented to two of the three groups differing in presentation mode (subliminal: n = 40, supraliminal: n = 41), neutral pictures were presented supraliminally to the control group (n = 41). Additionally, the effects of slow (3 cm/s) and fast (30 cm/s) stroking, applied either synchronously or asynchronously, were examined as the comforting effects of stroking might interfere with the emotion induction. Results showed that the supraliminal sadness induction was associated with a stronger subjective illusion, but not with a higher proprioceptive drift compared to the subliminal induction. In addition, a stronger subjective illusion after fast and synchronous stroking was found compared to slow and asynchronous stroking. A significant proprioceptive drift was detected independent of group and stroking style. Both slow and synchronous stroking were perceived as more comforting than their respective counterparts. Participants with higher dissociative symptoms were more susceptible to the subjective illusion, especially in the supraliminal group in the synchronous condition. We concluded that individual differences in emotion experience are likely to play a role in body ownership. However, we cannot clarify at this stage whether differences in proprioception and the subjective illusion depend on the type of emotion experienced (e.g. different levels of arousal) and on concomitant changes in multisensory integration processes.

Individuals with posttraumatic stress disorder (PTSD) are at increased risk for the development of various forms of dementia. Nevertheless, the neuropathological link between PTSD and neurodegeneration remains unclear. Degeneration of the human basal forebrain constitutes a pathological hallmark of neurodegenerative diseases, such as Alzheimer's and Parkinson's disease. In this seed-based resting-state (rs-)fMRI study identifying as outcome measure the temporal BOLD signal fluctuation magnitude, a seed-to-voxel analyses assessed temporal correlations between the average BOLD signal within a bilateral whole basal forebrain region-of-interest and each whole-brain voxel among individuals with PTSD (n = 65), its dissociative subtype (PTSD+DS) (n = 38) and healthy controls (n = 46). We found that compared both with the PTSD and healthy controls groups, the PTSD+DS group exhibited increased BOLD signal variability within two nuclei of the seed region, specifically in its extended amygdaloid region: the nucleus accumbens and the sublenticular extended amygdala. This finding is provocative, because it mimics staging models of neurodegenerative diseases reporting allocation of neuropathology in early disease stages circumscribed to the basal forebrain. Here, underlying candidate etiopathogenetic mechanisms are neurovascular uncoupling, decreased connectivity in local- and large-scale neural networks, or disrupted mesolimbic dopaminergic circuitry, acting indirectly upon the basal forebrain cholinergic pathways. These abnormalities may underpin reward-related deficits representing a putative link between persistent traumatic memory in PTSD and anterograde memory deficits in neurodegeneration. Observed alterations of the basal forebrain in the dissociative subtype of PTSD point towards the urgent need for further exploration of this region as a potential candidate vulnerability mechanism for neurodegeneration in PTSD.

BACKGROUND: Although numerous studies have supported the role of childhood maltreatment in the etiology of psychosis, underlying mechanisms have not been well understood yet. The present study aimed to investigate the mediating role of particular forms of dissociation in the relationship between five major types of childhood abuse and psychotic symptoms among patients with schizophrenia spectrum and other psychotic disorders. METHODS: In this cross-sectional correlation study, 70 first-episode psychotic patients and 70 chronic psychotic patients were selected by systematic random sampling (with the sampling interval of 3) from among inpatients and outpatients referring to Baharan Psychiatric hospital, Zahedan, Iran, and were matched based on age, gender, and education level. Moreover, 70 age-, gender-, and education level-matched community controls were recruited from hospital staff and their relatives and friends. All of the participants completed a research interview and questionnaires. Data on experiences of childhood maltreatment, psychosis, dissociation, and demographics were collected and analyzed by SPSS V25 software. RESULTS: The obtained results revealed that the mean scores of sexual abuse, emotional abuse, and physical abuse were higher in psychotic patients than community controls (without any significant difference between first-episode psychotic patients and chronic psychotic patients). Furthermore, the highest mean scores of dissociative experiences belonged to chronic psychotic patients. Multiple-mediation also indicated that absorption and dissociative amnesia played a mediating role in the relationship between sexual abuse and positive symptoms. Moreover, this study demonstrated the role of physical abuse in predicting psychotic symptoms even in the absence of sexual abuse. CONCLUSIONS: This study illustrated specific associations among childhood maltreatment, dissociative experiences, and psychotic symptoms in the clinical population. Thus, to provide appropriate interventions, patients with schizophrenia spectrum and other psychotic disorders were asked about a wide range of possible adverse childhood experiences and dissociative experiences. Nevertheless, further studies using prospective or longitudinal designs need to be carried out to realize the differential contribution of various forms of childhood maltreatment and their potential interactions, more precisely.

OBJECTIVE: Dissociative experiences commonly occur in response to trauma, and while their presence strongly affects treatment approaches in posttraumatic spectrum disorders, their etiology remains poorly understood and their phenomenology incompletely characterized. Methods to reliably assess the severity of dissociation symptoms, without relying solely on self-report, would have tremendous clinical utility. Brain-based measures have the potential to augment symptom reports, although it remains unclear whether brain-based measures of dissociation are sufficiently sensitive and robust to enable individual-level estimation of dissociation severity based on brain function. The authors sought to test the robustness and sensitivity of a brain-based measure of dissociation severity. METHODS: An intrinsic network connectivity analysis was applied to functional MRI scans obtained from 65 women with histories of childhood abuse and current posttraumatic stress disorder (PTSD). The authors tested for continuous measures of trauma-related dissociation using the Multidimensional Inventory of Dissociation. Connectivity estimates were derived with a novel machine learning technique using individually defined homologous functional regions for each participant. RESULTS: The models achieved moderate ability to estimate dissociation, after controlling for childhood trauma and PTSD severity. Connections that contributed the most to the estimation mainly involved the default mode and frontoparietal control networks. By contrast, all models performed at chance levels when using a conventional group-based network parcellation. CONCLUSIONS: Trauma-related dissociative symptoms, distinct from PTSD and childhood trauma, can be estimated on the basis of network connectivity. Furthermore, between-network brain connectivity may provide an unbiased estimate of symptom severity, paving the way for more objective, clinically useful biomarkers of dissociation and advancing our understanding of its neural mechanisms.

ABSTRACT: Both borderline personality features and dissociative symptoms have been associated with different types of childhood trauma. The aim of this investigation was to analyze to what extent emotional, physical, and sexual child maltreatment predict borderline personality features and dissociative symptoms. For this purpose, we analyzed data from 86 consecutively admitted patients who completed the Borderline Symptom List, the Childhood Trauma Questionnaire, and the German version of the Dissociative Experiences Scale for differential diagnosis of a borderline personality disorder. Hierarchical regression analyses revealed that borderline features were mainly predicted by emotional abuse, whereas pathological dissociation was best predicted by sexual and physical abuse. This evidence supports the hypothesis that different kinds of maltreatment may lead to different psychopathological symptoms in adulthood and should be taken into account in the therapy.

Background and Objectives: Anorexia nervosa (AN) is a complex disorder whose etiopathogenesis involves both biological and environmental factors. The aims of the present study were to retrospectively analyze risk factors in young patients with AN and to assess differences in clinical and eating-related symptoms between patients with and without a diagnosis of post-traumatic stress disorder (PTSD) and with or without a history of acknowledged risk factors. Materials and Methods: Sixty-four patients with AN (<25 years old) were recruited and completed an anamnestic evaluation and the following self-report measures: Eating Disorder Examination Questionnaire (EDE-Q), Childhood Trauma Questionnaire (CTQ), State-Trait Anxiety Inventory (STAI-Y), Beck Depression Inventory (BDI), Life Events Checklist (LEC), and Dissociative Experience Scale (DES). The PTSD diagnosis was assigned according to the Structured Clinical Interview for the DSM-5 (SCID-5). Results: The most frequent risk factors were those associated with relational traumatic events and familiarity for psychiatric disorders. Higher severity of body-related symptoms (i.e., those symptoms impacting on body image and perception and leading to body concerns) emerged in patients with PTSD, versus patients without PTSD diagnosis; however, after controlling for dissociative symptoms, only differences in BMI remained significant. Concerning other risk factors, those with a history of childhood trauma were more depressed than patients without such history and those with familiarity with eating disorders reported more AN-related hospitalizations in the past than those individuals without familiarity. Conclusion: These results suggest the importance of investigating the presence of risk factors and PTSD diagnosis in patients with AN, and to treat post-traumatic symptoms in young patients in order to decrease the risk of developing severe forms of AN. Moreover, a particular focus on those patients with a family member affected by an eating disorder could be of clinical utility.

In considering the applicability of hypnosis to treating Complex PTSD (C-PTSD) we examine the relationship between trauma, hypnosis, and dissociation, the latter being a common response to traumatization that is particularly salient in C-PTSD. We then provide an overview of the nature of C-PTSD, which research is beginning to demonstrate is considerably more prevalent than the more circumscribed PTSD syndrome depicted in the DSM. Building on this foundation, we discuss the reasons why hypnotically structured treatment is particularly well suited for C-PTSD, explaining how each of the major aspects of this syndrome can be addressed within a hypnotic framework.

OBJECTIVES: The study aimed to examine whether dissociation and attitudes towards change were associated with the psychopathology in patients with eating disorders (EDs) at 1-year follow-up. METHOD: The study included 110 females with anorexia nervosa and bulimia nervosa (48 and 62 respectively). At the beginning of the study and 1 year later, they were assessed by means of the following questionnaires: Dissociative Experiences Scale, Attitudes Towards Change (ACTA), State-Trait Anxiety Inventory, Rosenberg Self-Esteem Scale, Beck Depression Inventory, Eating Attitude Test, Bulimic Investigatory Test Edinburgh and Body Shape Questionnaire (BSQ). RESULTS: No statistically significant differences were found between both diagnostic groups regarding dissociation scores. The ACTA at baseline, specifically for patients in the contemplation stage, mediate the effect of dissociation on the psychopathological outcome. DISCUSSION: These findings suggest that dissociation might be a transdiagnostic feature related to the EDs outcome. The psychotherapeutic framework must take it into account, particularly in patients in the contemplation stage.

OBJECTIVE: Migraine is a complex episodic disease manifested by dysfunction of the sympathetic nervous system along with numerous neuropsychiatric symptoms. The aim of this study was to identify the dissociative symptoms with neurobiological similarities in episodic and chronic migraine patients and to evaluate their correlation with migraine frequency and severity of attacks. METHODS: The study included 61 episodic, 45 chronic migraine patients diagnosed using the criteria of the International Headache Society and 54 healthy control subjects. Dissociative Experiences Scale, Beck Anxiety Scale and Beck Depression Inventory were filled with the interviews. Demographic, clinical and headache characteristics of the patients were recorded according to migraine types. Results were analyzed by Kruskal-Wallis method and Spearman's correlation tests. RESULTS: Dissociative symptoms were more common in the patients with chronic migraine, and there was a statistically significant difference between the chronic migraine group and the episodic migraine and control groups (p = 0.001, p < 0.001). Dissociative experiences were correlated with depression and anxiety findings, and in both groups, there was a significant correlation between clinical characteristics of migraine and osmophobia in the controlled partial correlation analysis (p < 0.05). CONCLUSION: This study revealed that dissociative symptoms are more common especially in patients with chronic migraine and there is a significant association with osmophobia in both migraine groups. According to these data, we think that dissociative symptoms in chronic migraine patients will be questioned and osmophobia may be a guide in this regard.

BACKGROUND: Pineal lesions are common causes of dorsal midbrain syndrome and typically require surgical intervention in symptomatic patients. We describe a unique case of spontaneous resolution of dorsal midbrain syndrome resulting from a pineal gland cyst. CASE DESCRIPTION: A 23-year-old woman developed a supranuclear upgaze palsy, convergence-retraction nystagmus, and light-near dissociation from a pineal gland cyst (1.0 × 1.3 × 1.2 cm) with mild mass effect on the posterior surface of the tectum. Seven days after symptom onset, she had complete, spontaneous resolution of her symptoms, and examination returned to normal. Repeat magnetic resonance imaging demonstrated an unchanged pineal cyst with new T2/fluid attenuated inversion recovery hyperintensity along the mesial surface of the left thalamus. CONCLUSIONS: Dorsal midbrain syndrome resulting from a pineal cyst may spontaneously improve even without a significant change in lesion size. This suggests that observation may be an appropriate initial management strategy.

Objective: Dissociation and trauma have a well-documented relationship, and dissociation is assumed to result from trauma exposure. If trauma generates dissociative psychopathology, it should be observed after exposure to disaster and be associated with disaster-related psychopathology. Few studies have focused specifically on dissociation as an outcome of disaster trauma. This study examined dissociation and its association with disaster-related psychopathology in survivors of five different disasters. Methods: In the first 6 postdisaster months, directly exposed survivors (N = 216) of mass shootings, floods, or a firestorm completed structured diagnostic interviews providing lifetime predisaster and postdisaster prevalent/incident psychiatric diagnoses and the Dissociative Experiences Scale (DES) 1-3 years after baseline. Results: DES scores were very low; only 1% met the DES Taxon signifying pathological dissociation. In multivariate models including predisaster lifetime major depression, lifetime panic disorder, lifetime generalized anxiety disorder, and lifetime alcohol use disorder; disaster-related PTSD; and number of incident somatoform symptoms as independent covariates, predisaster lifetime major depression and alcohol use disorder were independently associated with both general (DES score) and pathological (DES Taxon) dissociation, and postdisaster incident somatization symptoms were also associated with general dissociation, but postdisaster psychopathology including disaster-related PTSD was not associated with general or pathological dissociation. Conclusions: Neither general nor pathological dissociation was independently associated with disaster-related PTSD or other incident psychopathology. The only psychiatric disorders associated with dissociation were present before the disasters. Coupled with the low dissociation rates, these findings indicate that dissociation does not appear to be a mental health outcome of disaster trauma.
