About

Borderline personality disorder (BPD) is a common mental disorder in adolescents with significant individual and societal repercussions, characterized over the long term by emotional hyperresponsiveness, relational instability, identity disturbances and self-aggressive behavior. The etiology of BPD is multifactorial and involves exposure to traumatic life events, which are present in the majority of cases. This explains the very common co-morbidity between BPD and post-traumatic stress disorder (PTSD), which involves emotionally painful memory relapses of one or more traumatic events, associated with an emotional trauma avoidance syndrome (s). ) and hypervigilance. Brain imaging studies in adolescents with BPD have shown decreases in the volume of gray matter within the frontolimbic network, as well as a decrease in frontolimbic white matter bundles. These brain changes are considered to be biological markers of TPB. However, the exact same brain changes are seen in PTSD. Although it represents more than a third of adolescents hospitalized in psychiatry, neuroscientific studies of BPD in adolescence are still scarce. The expertise we have acquired in U1077 in adolescents with PTSD offers us an exceptional opportunity to characterize in BPD with and without PTSD structural anomalies, including the hippocampus, and functional at rest, never used for hour in the teenager's BPD. Beyond that, carrying out an 18-month follow-up of the patients will allow us to assess the predictive value of these anomalies on the level of general psychopathology in all the patients studied and the intensity of the symptoms of traumatic relapse in the patients with PTSD. This modeling of disorders integrating psychopathological, neuropsychological and neuroanatomical approaches will provide the clinician with new knowledge necessary for therapeutic innovation.

A - RESEARCH OBJECTIVES

1. Primary objective:

   • Compare the hippocampal volume between adolescent girls with BPD with and without PTSD

2. Secondary objectives:

   • 1 - Evaluate the link, transverse and long-term (18 months), between the hippocampal volume and the level of general psychopathology in all the patients studied, and between the hippocampal volume and the intensity of the symptoms of traumatic revival in adolescent girls with PTSD.
   • 2 - Compare the volume of the hippocampal subfields between adolescent girls with BPD with and without PTSD, and assess in patients with PTSD the link, transverse and long-term (18 months), between volumes of the hippocampal sub-fields and intensity symptoms of traumatic revival
   • 3 - Compare the volume and integrity of the white matter bundles of the fronto-limbic network between adolescent girls with BPD with and without PTSD
   • 4 - Compare resting brain activity between adolescent girls with BPD with and without PTSD
   • 5 - Explore the links between changes in the brain and the intensity of the main psychological alterations associated with BPD in adolescence: i) attachment insecurity; ii) emotional dysregulation; iii) attention deficit and dysexecutive syndrome; iv) hypermentalization; and v) autobiographical memory and dissemination of identity.

B - Secondary evaluation criteria:

• 1 - Hippocampal volume (VBM); Global Clinical Assessment Scale score (CGA-S; Endicott et al., 1976); "Réviviscences" score in the French version of the UCLA Post-Traumatic Stress Disorder Reaction Index for Children and Adolescents (UCLA PTSD-RI C / A; Steinberg et al., 2013).
• 2 - Volume of each hippocampal subfield (Ammon's Horn [CA] 1, CA2, CA3, dentate gyrus, subiculum: anatomical MRI; Region Of Interest [ROI] method; Postel et al., 2019); "Intrusion" score of the French version of the UCLA PTSD-RI C / A.
• 3 - Orbitofrontal and cingulate cortex volume (VBM); anisotropy fraction (fractional anisotropy; FA) and average diffusivity (apparent diffusion coefficient; ADC) of fronto-limbic white matter beams (IRM Diffusion Tensor Imaging [DTI]; Le Bihan et al., 2001).
• 4 - Functional connectivity of brain networks in the resting state: default network (default mode network), salience network and central executive network; Viard et al., 2019).
• 5 - Brain modifications (VBM, ROI, AF, ADC, functional connectivity of resting networks) and: i) "Insecure attachment" score to Individual Relationship Model Cards (Ca-MIR; Pierrehumbert et al., 1996); ii) score "Separation-distress" and "Fear" in the French version of the Affective Neuroscience Personality Scale (ANPS; Pahlavan et al., 2008); iii) Continuous Performance Test omission score (CPT; Conners, 2002) and Wisconsin Card Sorting Test perseverance score (WCST; Heaton et al., 1993); iv) "Hypermentalisation" score in the French version of the Movie Assessment of Social Cognition (MASC; Martinez et al., 2017) and of the Reflective Functioning Questionnaire (RFQ; Badoud et al., 2015); and v) measurement of the quality of autobiographical productions (Reese et al., 2011), total score in the French version of the Assessment of Identity Development in Adolescence (AIDA; Goth et al., 2012).
