ABSTRACT
BACKGROUND:
Accurate early diagnosis of adolescent borderline personality disorder (BPD) is critical for prompt treatment. The aim of this study was to assess the alteration of brain surface morphology and to evaluate its relationship with core features in adolescent BPD.METHODS:
A total of 52 adolescents with BPD aged 12-17 years and 39 age- and sex-matched healthy controls (HCs) were prospectively enrolled into the study. Brain magnetic resonance imaging (MRI) was obtained with both 3D-T1 weighted structural sequence and resting-state functional data. The structural data was analyzed for surface morphology parameters including the local gyrification index (LGI), mean curvature and surface area. The functional MRI data was analyzed for seed-based functional connectivity (FC). Correlative analysis of surface morphology and core features of adolescent BPD was performed.RESULTS:
Adolescents with BPD showed the following altered surface morphology in the limbic-cortical circuit when compared to the HCs (1) reduced LGI in the left fusiform and right superior temporal gyrus; (2) reduced mean curvature in the left precentral gyrus and right rostral anterior cingulate cortex, and increased mean curvature in the bilateral pericalcarine; and (3) reduced surface area in the left paracentral gyrus, left pars triangularis, right insula and right lateral orbitofrontal gyrus (P < 0.05, FWE correction). In addition, these brain regions with altered surface morphology were significantly correlated with several core features including the mood instability, self-identity problems, and non-suicidal self-injury behavior in adolescents with BPD (P < 0.05). Furthermore, there was enhanced functional connectivity among these altered brain regions within the limbic-cortical circuit (voxel P < 0.001, cluster P < 0.05, FWE corrected).CONCLUSIONS:
Adolescents with BPD had significant alterations of brain surface morphology in the limbic-cortical circuit, which was correlated with core BPD features. These results implicated the surface morphology parameters and FC alterations may potentially serve as neuroimaging biomarkers for adolescents with BPD.Palavras-chave
