Le diable à Küsnacht : psychanalyse jungienne des possessions

Constatant une lente érosion de la place du religieux dans nos sociétés modernes, ainsi qu'une construction - voire un bricolage - d'une foi et d’une pratique religieuses plus individualistes, cette recherche vise à porter un regard psychanalytique jungien sur les manifestations de possessions diaboliques en tant que miroir, s'il en est un, de ces errances religieuses. Quelle place les possessions ont-elles tenue à travers l’histoire des religions chrétiennes? Comment se manifestent et comment sont reçues aujourd'hui les pérégrinations du diable? Est-il possible qu'une lecture jungienne de ces phénomènes nous amène à réaffirmer l'inévitable dissociabilité de la psyché, et comment cette variable pourrait-elle permettre au clinicien de mieux comprendre et appréhender les phénomènes de possession? Ce travail de recherche se présente tout d’abord par une confrontation d’un clinicien à deux cas de possession diabolique dans son bureau, autour desquels s’articulent ensuite plusieurs volets qui permettent d’appréhender, chacun à leur façon, un des aspects des possessions diaboliques : l’aspect historique, psychiatrique, sociologique et enfin le volet plus spécifiquement jungien. Cette recherche se conclut sur un dernier cas clinique de possession à travers lequel l’ensemble des différents volets abordés permet au clinicien d’élaborer différemment la problématique des possessions, ainsi que leur contenu archétypal.

Cognitive inhibition and interference in dissociative indentity disorder: the effects of anxiety on specific executive functions:The effects of anxiety on specific executive functions

Using an experimentally based, computer-presented task, this study assessed cognitive inhibition and interference in individuals from the dissociative identity disorder (DID; n=12), generalized anxiety disorder (GAD; n=12) and non-clinical (n=12) populations. Participants were assessed in a neutral and emotionally negative (anxiety provoking) context, manipulated by experimental instructions and word stimuli. The DID sample displayed effective cognitive inhibition in the neutral but not the anxious context. The GAD sample displayed the opposite findings. However, the interaction between group and context failed to reach significance. There was no indication of an attentional bias to non-schema specific negative words in any sample. Results are discussed in terms of the potential benefit of weakened cognitive inhibition during anxious arousal in dissociative individuals.

Auditory hallucinations in dissociative identity disorder and schizophrenia with and without a childhood trauma history: Similarities and differences.

Little is known about similarities and differences in voice hearing in schizophrenia and dissociative identity disorder (DID) and the role of child maltreatment and dissociation. This study examined various aspects of voice hearing, along with childhood maltreatment and pathological dissociation in 3 samples: schizophrenia without child maltreatment (n = 18), schizophrenia with child maltreatment (n = 16), and DID (n = 29). Compared with the schizophrenia groups, the DID sample was more likely to have voices starting before 18, hear more than 2 voices, have both child and adult voices and experience tactile and visual hallucinations. The 3 groups were similar in that voice content was incongruent with mood and the location was more likely internal than external. Pathological dissociation predicted several aspects of voice hearing and appears an important variable in voice hearing, at least where maltreatment is present.

A review of the dissociative disorders: from multiple personality disorder to the posttraumatic stress

In this paper we review the idea of dissociation, dissociative disorders and their relationship with the processes of consciousness. We will deal specifically with multiple personality disorder and posttraumatic stress disorder. Both polarize the discussion of diagnostic categories with dissociative symptoms. This review compares the initial ideas (one century old) with the current scenario and emerging trends in research, which are relating cognitive processes and dissociative phenomena and disorders from a neuroscientific approach. We discuss the ideas on dissociation, hypnosis and suicide associated with these disorders. There seems to be a lack of consensus as to the nature of dissociation with theoretical, empirical and clinical implications.

Somatoform and dissociative disorders

• The somatoform disorders are psychiatric illnesses that present as physical disorders. • The somatoform disorders are not to be confused with malingering, which is the intentional production of symptoms to avoid some responsibility or duty. • Somatisation is a method of expressing anxiety and distress and is found in all cultural groups. • The distress and suffering experienced by clients with a somatoform disorder are real, although the medical basis for their symptoms is not. • Clients with a somatoform disorder are most frequently encountered in primary health care settings. • The dissociative disorders are marked by an abrupt, temporary change in consciousness, cognition, memory, identity or behaviour.

A memory-based model of posttraumatic stress disorder: evaluating basic assumptions underlying the PTSD diagnosis.

In the mnemonic model of posttraumatic stress disorder (PTSD), the current memory of a negative event, not the event itself, determines symptoms. The model is an alternative to the current event-based etiology of PTSD represented in the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; American Psychiatric Association, 2000). The model accounts for important and reliable findings that are often inconsistent with the current diagnostic view and that have been neglected by theoretical accounts of the disorder, including the following observations. The diagnosis needs objective information about the trauma and peritraumatic emotions but uses retrospective memory reports that can have substantial biases. Negative events and emotions that do not satisfy the current diagnostic criteria for a trauma can be followed by symptoms that would otherwise qualify for PTSD. Predisposing factors that affect the current memory have large effects on symptoms. The inability-to-recall-an-important-aspect-of-the-trauma symptom does not correlate with other symptoms. Loss or enhancement of the trauma memory affects PTSD symptoms in predictable ways. Special mechanisms that apply only to traumatic memories are not needed, increasing parsimony and the knowledge that can be applied to understanding PTSD.

La schizophrénie dissociative : nouvelle entité clinique, trouble comorbide ou autres considérations nosographiques

L’existence d’un sous-type dissociatif de schizophrénie a été suggérée par plusieurs auteurs pour rendre compte des présentations symptomatologiques d’un groupe de personnes dont le diagnostic principal est dans le spectre de la schizophrénie mais qui présentent aussi des symptômes dissociatifs (Ross, 2004; Şar et al., 2010; Van der Hart, Witztum, & Friedman, 1993). D’origine traumatique, ce type de portrait clinique où symptômes psychotiques et dissociatifs s’entremêlent aurait été décrit il y a déjà plus d’un siècle (Janet & Raymond, 1898) mais serait disparu dans les années ’30, assimilé au concept de « schizophrénie » (Rosenbaum, 1980). C’est dans un nouveau contexte nosographique que le concept de schizophrénie dissociative refait surface. En effet, la nosographie psychiatrique a pris un tournant en 1980 lorsque l’approche préconisée par le DSM est devenue descriptive plutôt que basée sur des conceptualisations psychanalytiques. Du coup, les affections d’alors ont été divisées en troubles dont les symptômes ont tendance à se manifester ensemble (Cooper, 2004) et la comorbidité entre les troubles a augmenté. Étant donné la comorbidité fréquemment rapportée entre les troubles psychotiques et dissociatifs, la similarité phénoménologique de leurs symptômes, ainsi que leur possible étiologie traumatique, Ross (2004) a proposé une série de critères permettant de diagnostiquer une schizophrénie dissociative. L’objectif principal de cette thèse est donc d’établir si la schizophrénie dissociative, telle que définie par Ross (2004), existe. Le premier article porte sur la problématique et le contexte théorique ayant mené à la question de recherche. Il vise à faire un survol des enjeux entourant la question de la schizophrénie dissociative et rend compte des écrits scientifiques sur la symptomatologie similaire entre les troubles psychotiques et dissociatifs, sur leur étiologie traumatique et sur les études sur la dissociation et la schizophrénie. Le deuxième article est quant à lui un article empirique rendant compte de la méthodologie utilisée pour répondre à la question de recherche. En effet, aucune étude jusqu’ici n’a testé systématiquement les critères de la schizophrénie dissociative. Nos résultats démontrent que 24% de notre échantillon (N=50) pourrait recevoir le diagnostic de schizophrénie dissociative avec les critères proposés par Ross (2004). Toutefois, ces critères posant problème, une modification a été proposée et une prévalence de 14% a alors été trouvée. Des vignettes cliniques sont présentées afin de comparer nos participants avec ceux rapportés ailleurs. Les liens entre symptômes psychotiques et dissociatifs sont discutés en essayant de conceptualiser la schizophrénie dissociative de différentes manières, soit comme une nouvelle entité clinique, comme un trouble comorbide ou dans un contexte nosographique psychodynamique.

Limbic brain responses in mothers with post-traumatic stress disorder and comorbid dissociation to video clips of their children.

Maternal dissociative symptoms which can be comorbid with interpersonal violence-related post-traumatic stress disorder (IPV-PTSD) have been linked to decreased sensitivity and responsiveness to children's emotional communication. This study examined the influence of dissociation on neural activation independently of IPV-PTSD symptom severity when mothers watch video-stimuli of their children during stressful and non-stressful mother-child interactions. Based on previous observations in related fields, we hypothesized that more severe comorbid dissociation in IPV-PTSD would be associated with lower limbic system activation and greater neural activity in regions of the emotion regulation circuit such as the medial prefrontal cortex and dorsolateral prefrontal cortex (dlPFC). Twenty mothers (of children aged 12-42 months), with and without IPV-PTSD watched epochs showing their child during separation and play while undergoing functional magnetic resonance imaging (fMRI). Multiple regression indicated that when mothers diagnosed with IPV-PTSD watched their children during separation compared to play, dissociative symptom severity was indeed linked to lowered activation within the limbic system, while greater IPV-PTSD symptom severity was associated with heightened limbic activity. Concerning emotion regulation areas, there was activation associated to dissociation in the right dlPFC. Our results are likely a neural correlate of affected mothers' reduced capacity for sensitive responsiveness to their young child following exposure to interpersonal stress, situations that are common in day-to-day parenting.

Perception of a hectic hospital environment at admission relates to acute stress disorder symptoms in myocardial infarction patients.

OBJECTIVE Hospital crowding is a public health problem that may impact on the quality of medical treatment and increase the risk of developing traumatic stress, e.g., after myocardial infarction (MI). This study examines whether subjective appraisal of crowding at hospital admission due to MI is associated with acute stress disorder (ASD) symptoms. METHOD We investigated 102 consecutive patients with acute MI within 48h after having reached stable circulatory conditions. The appraisal of crowding was measured by the retrospective assessment of the perception of a hectic hospital environment at admission. Furthermore, patients completed the Acute Stress Disorder Scale to rate the psychological stress reaction. RESULTS The perception of a hectic hospital environment was associated with the development of ASD symptoms (r=0.254, P=.013) independently of demographic, peritraumatic and medical factors. Post hoc analysis revealed associations with dissociative (r=0.211, P=.041), reexperiencing (r=0.184, P=.074) and arousal (r=0.179, P=.083) symptoms. CONCLUSION The findings suggest that, besides objective circumstances, the way hospital admission due to MI is perceived by the patient may influence the development of MI-triggered ASD symptoms. The psychological and physiological long-term outcomes of the perception of a hectic hospital environment and the role of preventive interventions need further examination.
