Brain MRI of teenage girls with borderline personality disorder, with and without PTSD

Official title: NEUROIMAGERIE DU TROUBLE DE LA PERSONNALITE BORDERLINE A L'ADOLESCENCE AVEC ET SANS TROUBLE DE STRESS POST-TRAUMATIQUE

Run by University Hospital, Caen · NCT04852744 · Data updated 2026-11-12

This project will use MRI scans to see if hippocampus size and other brain measures differ between adolescent girls with borderline personality disorder who do and do not have PTSD.

Is this trial a fit for you?

Likely a good fit

Female adolescents aged 13–17 who speak French, have DSM-5 borderline personality disorder, can provide assent with parental consent, and have a general psychopathology level compatible with participation (CGA-S > 20) are ideal candidates.

Probably not a fit

Boys, people outside the 13–17 age range, non‑French speakers, those without BPD, or adolescents with clinical instability that prevents safe MRI participation are unlikely to benefit from joining this project.

What this trial studies

This interventional imaging project enrolls female adolescents (13–17) with borderline personality disorder, some of whom also meet criteria for PTSD, plus a healthy control group, and collects brain MRI data. The primary focus is on hippocampal volume and hippocampal subfields, with additional analyses of fronto-limbic white matter and resting brain activity. Clinical measures of general psychopathology, PTSD symptom intensity, attachment, emotion regulation, attention/executive function, mentalization, and autobiographical memory are collected and linked to imaging findings. Participants are followed cross-sectionally and with a planned 18-month longitudinal link between brain measures and symptom trajectories.

Why it matters

Potential benefit: If successful, this work could identify brain markers that help distinguish BPD with versus without PTSD in adolescents and guide more targeted monitoring or treatment strategies.

How similar studies have gone: Prior neuroimaging studies in adolescents and adults have reported fronto-limbic and hippocampal changes in BPD and in PTSD, so the approach builds on existing findings though direct longitudinal comparisons in adolescent girls are relatively limited.
