Titre : Brain structural trajectories in youth at familial risk for schizophrenia or bipolar disorder according to development of psychosis spectrum symptoms Type de document : texte imprimé Auteurs : Gisela SUGRANYES, Auteur ; Elena DE LA SERNA, Auteur ; Daniel ILZARBE, Auteur ; Jose Carlos PARIENTE, Auteur ; Roger BORRAS, Auteur ; Soledad ROMERO, Auteur ; Mireia ROSA, Auteur ; Inmaculada BAEZA, Auteur ; Maria Dolores MORENO, Auteur ; Miguel BERNARDO, Auteur ; Eduard VIETA, Auteur ; Josefina CASTRO-FORNIELES, Auteur Article en page(s) : p.780-789 Langues : Anglais (eng) Mots-clés : Adolescent Bipolar Disorder/diagnostic imaging Brain/diagnostic imaging Cross-Sectional Studies Genetic Predisposition to Disease Humans Magnetic Resonance Imaging Psychotic Disorders/diagnostic imaging Schizophrenia/diagnostic imaging/genetics High-risk studies bipolar psychosis schizophrenia structural MRI Index. décimale : PER Périodiques Résumé : BACKGROUND: The evaluation of child and adolescent offspring of patients with schizophrenia (SzO) or bipolar disorder (BpO) may help understand changes taking place in the brain in individuals at heightened risk for disease during a key developmental period. METHODS: One hundred twenty-eight individuals (33 SzO and 46 BpO, considered jointly as 'Familial High Risk' (FHR), and 49 controls) aged 6-17 years underwent clinical, cognitive and neuroimaging assessment at baseline, 2- and 4-year follow-up. Twenty FHR participants (11 SzO and 9 BpO) developed psychotic spectrum symptoms during follow-up, while 59 FHR participants did not. Magnetic resonance imaging was performed on a 3Tesla scanner; cortical surface reconstruction was applied to measure cortical thickness, surface area and grey matter volume. RESULTS: FHR participants who developed psychotic spectrum symptoms over time showed greater time-related mean cortical thinning than those who did not and than controls. By subgroups, this effect was present in both BpO and SzO in the occipital cortex. At baseline, FHR participants who developed psychotic spectrum symptoms over time had smaller total surface area and grey matter volume than those who did not and than controls. Over time, all FHR participants showed less longitudinal decrease in surface area than controls. In those who developed psychotic spectrum symptoms over time, this effect was driven by BpO, while in those who did not, this was due to SzO, who also showed less grey matter volume reduction. CONCLUSION: The emergence of psychotic spectrum symptoms in FHR was indexed by smaller cross-sectional surface area and progressive cortical thinning. Relative preservation of surface area over time may signal different processes according to familial risk. These findings lay the foundation for future studies aimed at stratification of FHR youth.

Titre : Sex differences and implications in outcome in children and adolescents at clinical high risk for psychosis Type de document : texte imprimé Auteurs : Jordina TOR, Auteur ; Inmaculada BAEZA, Auteur ; Xavier ALVAREZ-SUBIELA, Auteur ; Marta RODRIGUEZ-PASCUAL, Auteur ; Daniel MUÑOZ-SAMONS, Auteur ; Anna SINTES-ESTEVEZ, Auteur ; Elena DE LA SERNA, Auteur ; Olga PUIG, Auteur ; Gisela SUGRANYES, Auteur ; Daniel ILZARBE, Auteur ; Josep Maria HARO, Auteur ; Montserrat DOLZ, Auteur Article en page(s) : p.1461-1472 Langues : Anglais (eng) Mots-clés : Sex differences clinical high risk for psychosis children and adolescents psychosis outcome Index. décimale : PER Périodiques Résumé : Background Sex differences have been identified in young adults along the psychosis continuum, but studies in children and adolescents are scarce. This study aimed to evaluate possible sex differences in clinical characteristics and outcomes in children and adolescents with clinical high risk for psychosis (CHR). Methods A naturalistic longitudinal cohort study assessed sociodemographics, CHR symptoms, functioning, and mood at baseline and at 18 months' follow-up in 221 CHR participants (154 females and 67 males) and 159 controls (93 females and 66 males). Regression analyses were performed to test baseline differences, and multinominal regression was used to test the implication of sex in outcome. Results Despite initial pairwise differences in attenuated positive symptoms, regression analyses failed to show sex differences in CHR symptoms when control group was added to the analyses. The interaction between sex and group significantly predicted depressive symptoms (B 2.907, p .040, 95% CI: [ 5.681, 0.133]) and caffeine use lifetime (OR 0.36, 95% CI: [0.138, 0.924], p .034). A significant interaction between age and sex showed that the older the age in females, the greater the probability of non-remission of CHR at follow-up, as compared to males (B 0.338, IC 95%: [0.123, 0.933], p .036), but no relevant associations with sex were found in psychosis outcome. Conclusions No sex-related differences in CHR symptoms were observed in a CHR children and adolescent population. Outcomes related to non-remission of CHR state in older females could reflect the greater prevalence of psychosis-like experiences in adolescent females. These results invite us to reconsider the usefulness of the current CHR criteria in young populations, especially if we do not take into account a gender perspective and how age might affect it.
