L’épidémiologie des Troubles des conduites alimentaires (TCA) permet d’envisager que la problématique dans ces affections soit liée en grande partie à la problématique plus générale de la féminité et à celle de la constitution de l’identité de genre psychique et corporelle à l’adolescence. Nous allons particulièrement aborder ici la problématique d...
Borderline personality disorders account for 50% of adolescent hospitalization cases in psychiatry. The severity and psychopathological complexity of these symptoms indicate the need for inclusive models of understanding. Adopting a holistic approach allows for the consideration of not only the patient's environment, but also their position within...
Introduction
Emotion regulation is altered in many psychiatric disorders in adolescence, but the understanding of mechanisms that underlie this alteration is still poor.
Methods
The PERCEPT study explores alexithymia, empathy, facial emotion recognition (FER) and defence mechanisms in a sample of adolescents in psychiatric care ( n = 61, 74% of gi...
Background:
The extent and nature of sexual abuse (SA) and its consequences in psychiatry are still poorly described in adolescence.
Objective:
This article describes the frequency of SA reported in an adolescent population hospitalized in psychiatry, and assesses its links with the severity of mental disorders and the medical issues of these ad...
Malgré l'enjeu majeur de santé publique qu'elles représentent, les maltraitances infantiles, et particulièrement les négligences, restent sous-estimées en psychiatrie, tant dans leur prévalence que leur impact sur la santé. De plus, le phénomène de mal-traitance reste habituellement associé à un fort déterminisme socio-culturel et est très peu éval...
Background
Literature data about emotion perception in patients with borderline personality disorders (BPD) revealed some discrepancies between some patients that are vigilant and accurate to detect their emotional environment and others that are impaired at identifying emotions of others. Even if some links between childhood adversity and facial a...
Anorexia nervosa is a psychiatric disorder that mainly affects women (sex ratio 1/10) and for which the prognosis remains poor (10% of deaths and high risk of chronicity). This disorder is associated with a risk of infertility explained by different physiopathological pathways. Thus, the clinical and subclinical forms of this disease may be over-re...
The epidemiology of adolescent psychiatric disorders and the relational complexity of their management make exposure to adolescent psychiatry essential during medical school. However, some clinical particularities can complicate the students’ learning experiences. Our work aimed to explore the experience of being a medical student during clerkships...
Background:
Randomized controlled trials showed the efficacy of family therapy for anorexia nervosa during adolescence, but studies examining its long-term beneficial effect are still needed. This article presents the results of a 54-month post-randomization follow-up of a previously reported randomized controlled trial that compared two post-hosp...
Although previous cross-sectional studies suggested significantly dysregulated immune response in alexithymia, there is a lack of longitudinal studies. We sought to determine the reliability of the reported relationship between alexithymia and decreased immune response in a longitudinal study. Thirty-eight healthy women who had participated in a cr...

Background
Anorexia nervosa (AN) mainly affects women (sex ratio 1/10) and most often starts during adolescence. The prognosis of AN remains poor (10% of deaths and high risk of chronicity). Body dissatisfaction, disturbances in recognition and identification of body sensations are some of the key symptoms of AN. However, there is a contrast betwee...
Au décours du confinement de mars 2020 lié à la Covid -19, nous avons pu observer une patientèle composée de jeunes souffrant de troubles des conduites alimentaires ayant décompensé pendant la période suspendue du confinement. Nous avons souhaité, après avoir décrit la présentation clinique de ces troubles qui nous a semblé singulière, nous interro...
Background: Psychopathological models of adolescent borderline personality disorder (BPD) suggest that non-suicidal self-injuring (NSSI)—a particularly frequent symptom in girls—may constitute a way of coping with distress resulting from interpersonal concerns they typically experience as a developmental psychopathological feature.
Objectives: Our...
Introduction: Borderline personality disorder (BPD) in adolescents is characterized by emotional dysregulation, insecure attachment, a history of stressful life events (SLEs) as well as dysfunctional parent–child interactions. The respective contribution of each of these factors on BPD affective symptoms is not yet clear. The purpose of this study...
In adolescent psychiatry, when patients present high-risk sexual behaviours, analysing the symptoms usually leads back to a traumatic sexual event in childhood. These clinical situations include a first stage in which the trauma is constituted and a second adolescent stage in which the mnemic trace can lead to the traumatic experience being reprodu...
Background
Emotional dysregulation seems to be a core feature of Borderline Personality Disorders (BPD). In addition, recent research in the adolescent population has shown that suicidal behaviours have been associated with maladaptive strategies of emotion regulation.
Methods
This study examined the relative contributions of emotional dysregulati...
The authors begin by presenting the epistemological foundations that enabled them to design a therapeutic mediation framework aimed at enhancing the treatment of hospitalized anorexic patients. This unique framework utilizes bodily exploration through sound and music vibration. The authors were inspired by a method of dynamic structuring of the bod...
Freud notait que Kral Krauss avait écrit que « Le coït n’est que le succédané insuffisant de la masturbation ». Il soulignait la pertinence de cette sentence en rappelant que l’important était les fantasmes qui accompagnaient la satisfaction… et que c’était bien cela qui était dramatique (succès damné). Puisqu’ils élevaient l’objet sexuel a un degr...
Objective
Among medically assisted procreation (MAP) patients, the prevalence of eating disorders (ED), clinical or subclinical, current or past, is considerable. In addition to metabolic repercussions, the literature suggests that these patients present with more sexual dysfunction, leading to anxiety.
This quantitative research on a population of...
Within the European Research Network on BPD (EURNET-BPD; n = 85 BPD adolescents, n = 84 healthy controls, aged 13–19), this study explored the combination of three types of adversity—maltreatment, stressful life events (early separation from parents, parental suicide attempt, parental chronic disease) and parental bonding—as predictors of BPD, on a...
Hypereality and belief
The real is not merely the excess that invades or overwhelms us; it is also what is not perceived as not having been sufficiently given and which always eludes us. On the individual and collective scale, it takes the form of economic rationale and unrealistic positivism.
Art, as a falsification of the real, is a useful remedy...
En particulier en ce qui concerne les symptômes de l’adolescent, la notion d’état limite a confirmé l’intérêt d’une attention dimensionnelle et développementale envers différents modes de fonctionnement psychique plutôt qu’une rigide approche catégorielle. À l’intérieur de ce cadre sémiologique, il en ressort une redéfinition de la notion de comorb...
This article presents the theoretical, scientific, and methodological foundations for the design and implementation of an innovative technological and clinical platform that combined sound, music, and vibrotactile mediation used in a therapeutic setting by adolescents suffering from anorexia nervosa. In 2019, we carried out a pilot experiment with...

Résumé
Objectif
Les étudiants en médecine, parfois encore eux-mêmes en phase adolescente, peuvent être amenés à effectuer un stage en psychiatrie de l’adolescent, où les patients ont un âge proche du leur. L’objectif de cette étude est d’explorer leur vécu afin de mieux les accompagner, tant dans les outils pédagogiques que dans les mouvements psy...
La psychothérapie institutionnelle est moribonde, appauvrie entre autres par la financiarisation des soins et l’ultrahygiénisme. Parallèlement à cette dyna- mique préoccupante de rapports de pouvoir laissant le soin relationnel pour compte, le contexte social laisse apparaître un mouvement de transition citoyenne qui contient dans ses principes com...
L’auteur souligne les apports vitaux de la sexualité à l’adolescence, rappelle les dangers de sa répression comme le risque de ses excès, de faire verser le sujet dans l’enfermement pervers et la destructivité plutôt que de favoriser sa créativité personnelle dans le jeu.
Background
Anorexia nervosa (AN) is a serious psychiatric illness that begins most of the time during adolescence. An early and efficacious intervention is crucial to minimize the risk of the illness becoming chronic and to limit the occurrence of comorbidities. There is a global consensus on optimal treatment for adolescents suffering from AN: int...
Adolescence is a period of biological, psychological, and psychosocial transformations during which internal mutations take place. On the basis of a clinical case of a teenager presenting with Crohn’s disease concomitantly with psychiatric disorders, we will discuss our interest concerning the coexistence of three pathological entities (Crohn’s dis...
Introduction
Techniquement le Light Painting est une prise de vue photographique qui consiste à révéler les traces lumineuses d’une source grâce à un temps d’exposition relativement lent. Il a été démontré que la prise de photos augmente la sensation hédonique jusqu’à l’accès à la joie et en même temps potentialise l’implication des sujets dans ce...
Les femmes enceintes souffrant de troubles des conduites alimentaires (TCA) ont le plus souvent une régression des symptômes pendant la grossesse, mais avec une aggravation fréquente dans le post-partum, ce qui ne sera pas sans effet sur la rencontre avec le bébé à venir.
L’objectif de cette étude a été d’évaluer l’expérience de la grossesse chez d...
Social worker educators and health care institutions are currently overwhelmed by teenagers named “tweeners,” often considered as “psychopaths.” Their main way of calling for help is by acting out. This results in both relational problems and attachment disorders. These symptoms prevent them from building transitional spaces in which to develop. To...
La psychogenèse de l’homosexualité féminine et la psychopathologie des troubles des conduites alimentaires (TCA) présentent des similarités, notamment concernant la place du féminin. La sexualité des TCA est un point nodal de cette psychopathologie, particulièrement à l’adolescence, moment sensible d’après-coup de la mise en place de l’axe narcissi...
Introduction: Experiencing adverse life events and early disturbed patterns of interaction are crucial determinants for the development of Borderline Personality Disorder (BPD). Parental suicidal attempts can be considered a major adverse life event and a potentially traumatic experience. The aim of this study was to examine differences in parental...
Several researchers point to disorganized attachment as a core feature of borderline personality disorder (BPD). However, recent studies suggest that specific internal working models (IWMs) of each parent combine to account for child outcomes and that a secure relationship with one parent can protect against the deleterious effects of an insecure r...

Introduction
La sémiologie post-traumatique présente des symptômes caractérisés notamment par des reviviscences du traumatisme. Ce tableau clinique peut s’enrichir des effets de la consommation puis de la dépendance aux drogues. Des liens sont établis aussi avec le trouble de personnalité limite. Nous revenons ici sur le concept de comorbid...
Résumé
Les troubles des conduites alimentaires à l’adolescence sont des troubles situés à l’intersection entre le soma et la psyché nécessitant, pour une prise en charge optimale, d’allier les compétences pédiatriques et psychiatriques. Leur compréhension doit se faire sur un mode développemental diachronique grâce à un modèle biopsychosocial perme...
The modelling of a traumatic complex, which proposes a revised description of borderline functioning, including the subset of borderline personality disorders, makes it significantly possible to consider the links of these pathologies to an addictive appetite depending on the determination of the patient that is both traumatophi-lic and self-therap...
Résumé
Introduction
Pour Winnicott, corps et self entretiennent un rapport étroit, puisque c’est du vrai self que provient le geste spontané, l’idée personnelle et le fait de se sentir réel. Le défaut d’accordage entre corps et psyché témoigne d’une difficulté à éprouver par son corps ce sentiment d’existence. Nous nous intéressons ici à l’enracin...
Longitudinal data point to disorganized attachment toward the mother as a risk factor in the development of borderline personality disorder (BPD). However, several authors posit that the deleterious effects of an insecure relationship with the mother can be moderated by a secure relationship with the father. A few studies do suggest that internal w...

Body, rhythm and creation
Using clinical encounters with contemporary artists (in this case, Boris), we explore the place of the body in creation, through the notion of rhythm. Rhythm is not limited to rhythmicity or tempo, nor measure alone; rather, it bears witness to the incarnation of internal movement. It is in its incarnation that rhythm exis...
Objective:
In recent decades, alexithymia has been considered a risk factor for multiple somatic and psychiatric conditions. Yet, whereas alexithymia has been extensively studied in adults with a substance misuse, only one study has reported data on cannabis abusers from the general population. Hence, our main objective was to explore alexithymia...
Anorexia is a reflection of issues with the body in all its states. The social body and the representation of a model's body, mistreated in order to meet certain standards, the medical body shaken by the mystery of anorexia, and the subjective body and the reality of the flesh. The anorexic body is a testament to a past full of pain and neglect, a...
Background:
The use of illicit substances, in particular cannabis, among French adolescents and young adults has become an important public health concern. A better understanding of the mechanisms involved in pathological substance use is nowadays critical. Psychiatric comorbidities have been previously reported in adult substance abusers but are...
Résumé
Plus de la moitié des troubles bipolaires diagnostiqués chez l’adulte débutent avant 18 ans. C’est un fait établi que l’adolescence est une période à haut risque de décompensation thymique et que les troubles bipolaires à début précoce bien que rares sont les plus sévères. Des antécédents de troubles bipolaires chez les apparentés du premier...
Everything that is grouped under the name of functional limits, anaclitic or narcissistic pathologies, or an identity crisis, currently appears as a topical pathology and "genuine social diseases". These disorders are largely determined by the "phenomenon of adolescence" singularly different today from that observed in previous generations.
Il est fréquent de penser que les femmes souffrant de trouble des conduites alimentaires (TCA) ne peuvent pas être enceintes (aménorrhée, irrégularités du cycle ovulatoire), mais plusieurs études [1–3] révèlent un nombre croissant de femmes souffrant d’un TCA parmi la population ayant recours aux divers traitements de l’infertilité. La stimulation...
Le trouble borderline est le plus fréquent des troubles de la personnalité, et sa prise en charge reste un enjeu majeur pour les psychiatres d’adultes, mais aussi pour les psychiatres d’adolescents et d’enfants. Le trouble borderline, même s’il trouve pour partie son étiopathogénie dans certaines anomalies génétiques, est aussi profondément caracté...

... Nonetheless, increased awareness about body image dissatisfaction and pathological eating behaviors allowed clinicians to also recognize the burden of eating disorders (EDs) [7], during the same period of life in women [8], improving diagnosis and treatment accordingly. Moreover, with improved diagnosis and treatment, the identification of reproductive health concerns has also increased for chronic ED patients [9,10]. For instance, complications are known to arise and impact the pregnancy of ED patients more frequently than the general population [11,12]. ...
... Bowlby (60) also proposed that early experiences of relational withdrawal from attachment figures have an impact on development, a finding supported by several studies linking insecure attachment and borderline symptoms (79)(80)(81). Adverse experiences can lead to distinct perceptual modifications, with relational withdrawal experiences correlating with hypersensitivity in facial emotion recognition and intrusion experiences associated with decreased emotional perceptual accuracy (82). In all cases, attention to the internal world is diminished, likely due to difficulties accessing early parental mirroring functions (83). ...
