  Abstract Neuroanatomical evidence on the relationship between posttraumatic stress disorder (PTSD) and dissociative disorders is still lacking. We acquired brain structural magnetic resonance imaging (MRI) scans from 17 patients with dissociative identity disorder (DID) and co-morbid PTSD (DID-PTSD) and 16 patients with PTSD but without DID (PTSD-only), and 32 healthy controls (HC), and compared their whole-brain cortical and subcortical gray matter (GM) morphological measurements. Associations between GM measurements and severity of dissociative and depersonalization/derealization symptoms or lifetime traumatizing events were evaluated in the patient groups. DID-PTSD and PTSD-only patients, compared with HC, had similarly smaller cortical GM volumes of the whole brain and of frontal, temporal and insular cortices. DID-PTSD patients additionally showed smaller hippocampal and larger pallidum volumes relative to HC, and larger putamen and pallidum volumes relative to PTSD-only. Severity of lifetime traumatizing events and volume of the hippocampus were negatively correlated. Severity of dissociative and depersonalization/derealization symptoms correlated positively with volume of the putamen and pallidum, and negatively with volume of the inferior parietal cortex. Shared abnormal brain structures in DID-PTSD and PTSD-only, small hippocampal volume in DID-PTSD, more severe lifetime traumatizing events in DID-PTSD compared with PTSD-only, and negative correlations between lifetime traumatizing events and hippocampal volume suggest a trauma-related etiology for DID. Our results provide neurobiological evidence for the side-by-side nosological classification of PTSD and DID in the DSM-5.

  Title Distinct intrinsic network connectivity patterns of post-traumatic stress disorder symptom clusters Type (up) Journal Article
  Year 2015 Publication Acta Psychiatrica Scandinavica Abbreviated Journal Acta Psychiatr Scand  
  Volume 132 Issue 1 Pages 29-38  
  Keywords adult survivors of child abuse; functional neuroimaging; multivariate analysis; post-traumatic stress disorders  
  Abstract OBJECTIVE: Post-traumatic stress disorder (PTSD) is considered a multidimensional disorder, with distinct symptom clusters including re-experiencing, avoidance/numbing, hyperarousal, and most recently depersonalization/derealization. However, the extent of differing intrinsic network connectivity underlying these symptoms has not been fully investigated. We therefore investigated the degree of association between resting connectivity of the salience (SN), default mode (DMN), and central executive (CEN) networks and PTSD symptom severity. METHOD: Using resting-state functional MRI data from PTSD participants (n = 21), we conducted multivariate analyses to test whether connectivity of extracted independent components varied as a function of re-experiencing, avoidance/numbing, hyperarousal, and depersonalization/derealization. RESULTS: Hyperarousal symptoms were associated with reduced connectivity of posterior insula/superior temporal gyrus within SN [peak Montreal Neurological Institute (MNI): -44, -8, 0, t = -4.2512, k = 40]. Depersonalization/derealization severity was associated with decreased connectivity of perigenual anterior cingulate/ventromedial prefrontal cortex within ventral anterior DMN (peak MNI: 8, 40, -4; t = -3.8501; k = 15) and altered synchrony between two DMN components and between DMN and CEN. CONCLUSION: Our results are consistent with prior research showing intrinsic network disruptions in PTSD and imply heterogeneous connectivity patterns underlying PTSD symptom dimensions. These findings suggest possible biomarkers for PTSD and its dissociative subtype.

  Title Assessing DSM-5 latent subtypes of acute stress disorder dissociative or intrusive? Type (up) Journal Article
  Year 2015 Publication Psychiatry Research Abbreviated Journal Psychiatry Res  
  Volume 225 Issue 3 Pages 476-483  
  Keywords Adult; Age Factors; *Diagnostic and Statistical Manual of Mental Disorders; Dissociative Disorders/classification/*diagnosis/psychology; Female; Humans; Male; Middle Aged; Risk Factors; Social Support; Stress Disorders, Traumatic, Acute/classification/*diagnosis/psychology; ASD subtypes; Dissociative ASD; Intrusive ASD; Latent profile analysis; Risk factors  
  Abstract Acute Stress Disorder (ASD) was first included in the DSM-IV in 1994. It was proposed to account for traumatic responding in the early post trauma phase and to act as an identifier for later Posttraumatic Stress Disorder (PTSD). Unlike PTSD it included a number of dissociative indicators. The revised DSM-5 PTSD criterion included a dissociative-PTSD subtype. The current study assessed if a dissociative-ASD subtype may be present for DSM-5 ASD. Moreover, we assessed if a number of risk factors resulted in an increased probability of membership in symptomatic compared to a baseline ASD profile. We used data from 450 bank robbery victims. Latent profile analysis (LPA) was used to uncover latent profiles of ASD. Multinomial logistic regression was used to determine if female gender, age, social support, peritraumatic panic, somatization, and number of trauma exposures increased or decreased the probability of profile membership. Four latent profiles were uncovered and included an intrusion rather than dissociative subtype. Increased age and social support decreased the probability of individuals being grouped into the intrusion subtype whereas increased peritraumatic panic and somatization increased the probability of individuals being grouped into the intrusion subtype. Findings are discussed in regard to the ICD-11 and the DSM-5.

  Title Posttraumatic stress in deployed Marines: prospective trajectories of early adaptation Type (up) Journal Article
  Year 2015 Publication Journal of Abnormal Psychology Abbreviated Journal J Abnorm Psychol  
  Volume 124 Issue 1 Pages 155-171  
  Keywords  
  Abstract We examined the course of PTSD symptoms in a cohort of U.S. Marines (N = 867) recruited for the Marine Resiliency Study (MRS) from a single infantry battalion that deployed as a unit for 7 months to Afghanistan during the peak of conflict there. Data were collected via structured interviews and self-report questionnaires 1 month prior to deployment and again at 1, 5, and 8 months postdeployment. Second-order growth mixture modeling was used to disaggregate symptom trajectories; multinomial logistic regression and relative weights analysis were used to assess the role of combat exposure, prior life span trauma, social support, peritraumatic dissociation, and avoidant coping as predictors of trajectory membership. Three trajectories best fit the data: a low-stable symptom course (79%), a new-onset PTSD symptoms course (13%), and a preexisting PTSD symptoms course (8%). Comparison in a separate MRS cohort with lower levels of combat exposure yielded similar results, except for the absence of a new-onset trajectory. In the main cohort, the modal trajectory was a low-stable symptoms course that included a small but clinically meaningful increase in symptoms from predeployment to 1 month postdeployment. We found no trajectory of recovery from more severe symptoms in either cohort, suggesting that the relative change in symptoms from predeployment to 1 month postdeployment might provide the best indicator of first-year course. The best predictors of trajectory membership were peritraumatic dissociation and avoidant coping, suggesting that changes in cognition, perception, and behavior following trauma might be particularly useful indicators of first-year outcomes.

  Title [Clinical forms of post-traumatic depression] Type (up) Journal Article
  Year 2015 Publication L'Encephale Abbreviated Journal Encephale  
  Volume 41 Issue 4 Pages 346-354

  Abstract INTRODUCTION: As a result of determinants specific to the psychopathological structure of the psychological trauma, psycho-traumatised patients very rarely solicit the health care system directly with a request for treatment centred on their trauma. The medical profession is consulted for non-specific symptoms and complications, which are mainly somatoform, addictions and depressive disorders. After a few epidemiological reminders followed by a discussion concerning contemporary depressive and post-traumatic nosographic features, we define, through our clinical experience collated with the data in the literature, different clinical and etiopathogenic contexts of post-traumatic depression in order to control their therapeutic treatment. CLINICAL FINDINGS: Burnout post-traumatic depression in response to re-experiencing is the most common: it is a reactive psycho-physiological burnout in response to the emotional distress re-experienced during flashbacks, insomnia, a constant feeling of insecurity and the deleterious consequences of this symptomatology in terms of social adaptation. A common genetic predisposition affecting serotoninergic regulation seems to be a vulnerability marker of both depressive and psychotraumatic symptoms. In this case, SSRI will be effective on sadness. In addition, these antidepressants have been widely prescribed for the first-line treatment of depressive and psychotraumatic symptoms. However, this pharmacological class is often insufficient in relieving autonomic hyperactivity such as re-experiencing which are mediated more by noradrenergic hyperactivity. SNRI such as venlafaxine can be used as a first-line treatment. Post-traumatic depression with psychotic features congruent with mood is dominated by a feeling of incurability; the subject blames himself and feels guilty about the traumatic event and its consequences. Symptoms of denial of identity are sometimes observed: confined by an intense depersonalization, the psycho-traumatised subject evokes that he is “no longer himself” and that his mind “is disconnected”. Confronted with the psychological emptiness of the traumatic scene, the psycho-traumatised subject remains devoid of thought as if their mind has left him. In addition to antidepressant therapy, an atypical antipsychotic drug must be prescribed to relieve the melancholic symptoms as well as the concomitant psychotraumatic symptoms. Post-traumatic depression masked by peripheral physical injuries is the result of accidents combining psychological and physical impairment. The physical pain resulting from the accident regularly recalls the drama in the same way as traumatic re-experiencing. Depression masked by this somatic suffering is difficult to diagnose, but the repeated somatic complaints at the forefront of the request for treatment, the breakdown of self-esteem as well as the level of subjective strain due to pain and dysesthesia are all indications. The psychotherapy will focus on the symbolic reconstruction of the organs that have been damaged or destroyed, with the aim of healing the extensive narcissistic impairment. Post-concussive depression is diagnosed following a head trauma, however severe. It is sometimes assigned to neurological lesions and at other times recognised as the expression of a purely psychological reaction. Antidepressant therapy, or possibly trial therapy, is often indicated. The terms traumatic grief and post-traumatic grief are often used synonymously in publications: a conceptual opposition must however been recalled. If the traumatic grief is the result of the loss of an object that holds much psychological importance for the individual, the subject has not however been traumatised by this event and is not suffering and will not suffer from re-experiencing. The therapy will include methods used in the psychotherapeutic treatment of grief; antidepressants are often insufficient. Differently, post-traumatic grief takes shape when the loss of another is concomitant with the confrontation with the reality of the death witnessed in a moment of peri-traumatic dissociation. This grief is often observed following the discovery of the body of a close friend or family member who has committed suicide, or when part of a family has been decimated by an accident whilst the survivors watch their close relations die pending the arrival of the emergency services, or when a military comrade is wounded in combat in front of his partner. The mourning process cannot really begin until the flashbacks cease. CONCLUSIONS: Clinical depression or even melancholia, possibly masked by somatic or post-concussive complaints, is often the initial mode of contact with the health care system for the psycho-traumatised subject. The different clinical and etiopathogenic contexts of post-traumatic depression that we have developed in this work use specific therapies which need to be clarified by further research based on this nosography.

  Title DSM-5's posttraumatic stress disorder with dissociative symptoms: challenges and future directions Type (up) Journal Article

  Abstract The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, formally recognizes a dissociative subtype of posttraumatic stress disorder (PTSD; PTSD with dissociative symptoms). This nomenclative move will boost empirical and theoretical efforts to further understand the links between dissociation, trauma, and PTSD. This article examines the empirical literature showing that patients with PTSD can be divided into 2 different groups based on their neurobiology, psychological symptom profile, history of exposure to early relational trauma, and depersonalization/derealization symptoms. It then explores the conceptual and empirical challenges of conceiving 1 of these types as reflecting a “dissociative” type of PTSD. First, this classification is based on the presence of a limited subset of dissociative symptoms (i.e., depersonalization, derealization). This sets aside an array of positive and negative psychoform and somatoform dissociative symptoms that may be related to PTSD. Second, empirical evidence suggests heightened dissociation in PTSD compared to many other disorders, indicating that dissociation is relevant to PTSD more broadly rather than simply to the so-called dissociative subtype. This article sets out important issues to be examined in the future study of dissociation in PTSD, which needs to be informed by solid conceptual understandings of dissociation.

  Title An expanded Metrosideros (Myrtaceae) to include Carpolepis and Tepualia based on nuclear genes Type (up) Journal Article
  Year 2015 Publication Systematic Botany Abbreviated Journal  
  Volume 40 Issue 3 Pages 782-790  
  Keywords  
  Abstract The genus Metrosideros (Myrtaceae) comprises 50-60 species, found largely across the Pacific Islands. The relationships within this genus, including the circumscriptions of the subgenera Mearnsia and Metrosideros and their relationships with the other members of the tribe Metrosidereae, namely the New Caledonian endemic genus Carpolepis and the South American Tepualia, are poorly understood. Phylogenetic analyses were carried out using previously published ITS sequences, covering most species of the tribe, and new sequences of five single-copy nuclear genes on a reduced sampling. The independent and combined analyses of the five nuclear genes using a range of approaches, including Bayesian single-gene, concatenated (MrBayes), concordance (BUCKy) and coalescent (*BEAST) analyses, yielded different topologies, indicating important conflicts among individual gene phylogenetic signals. The deep relationships within the tribe Metrosidereae remain poorly resolved, but our results indicate that the species of Carpolepis and Tepualia are likely nested in the genus Metrosideros. A broad circumscription of the genus Metrosideros is therefore adopted, and the new combinations Metrosideros laurifolia var. demonstrans, Metrosideros tardiflora and Metrosideros vitiensis are here published.

  Title High-resolution pollen record from Efate Island, central Vanuatu: Highlighting climatic and human influences on Late Holocene vegetation dynamics Type (up) Journal Article
  Year 2015 Publication Comptes Rendus Palevol Abbreviated Journal  
  Volume 14 Issue 4 Pages 251-261  
  Keywords  
  Abstract Climate changes, sea-level variations, volcanism and human activity have influenced the environment of the southwest Pacific Islands during the Holocene. The high-resolution palynological analysis presented here concerns two specific levels (main lithological changes) of a well-dated Holocene core, Tfer06, collected from Emaotfer Swamp, Efate Island (Vanuatu). Our aim is to understand the role of climatic variability and human activities in shaping vegetation during these changes. Between 3790–3600 cal yr BP, the development of vegetation marked by disturbance is a marker of an increase in sustained El Niño events, also observed in many Asian-West Pacific areas. Between 1500–900 cal yr BP, the increase in introduced taxa and in microcharcoal particles is interpreted as human impact. In a forthcoming paper, the ongoing high-resolution palynological analysis of the whole core will be compared and integrated into regional palaeoecological data.

  Title Rhopalotricha, a New Subgenus of the Fern Genus Lastreopsis (Dryopteridaceae) Type (up) Journal Article
  Year 2015 Publication American Fern Journal Abbreviated Journal  
  Volume 105 Issue 1 Pages 20-30  
  Keywords  
  Abstract A new subgenus of Lastreopsis, subg. Rhopalotricha, is here described based on the results of our recent phylogenetic analyses. Its species differ from others in the genus by having a distinctive type of hair within the grooves of the rachises and costae adaxially. These are 1–3(–4)-celled and clavate, whereas the remainders of the species in the genus have hairs that are 3–12-celled and non-clavate. Subgenus Rhopalotricha also differs by having spores with broadly folded perispores with echinulate surfaces (vs. tuberculate or spiny, and with smooth surfaces). Subgenus Rhopalotricha occurs in the Neotropics, islands of the southwestern Pacific (Samoa, Fiji, and Vanuatu), New Zealand, and Australia. A key is provided to distinguish the species, each of which is treated with synonymy, description, geographic distribution by country, elevation ranges, and discussions. Lectotypes are also designated for Dryopteris amplissima var. subeffusa, Aspidium macrum Fée, and Aspidium latissimum Fée.
