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.

Longitudinal study of neurological soft signs in first-episode early-onset psychosis / María MAYORAL in Journal of Child Psychology and Psychiatry, 53-3 (March 2012)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 53-3 (March 2012) . - p.323-331 Titre : Longitudinal study of neurological soft signs in first-episode early-onset psychosis Type de document : texte imprimé Auteurs : María MAYORAL, Auteur ; I.

The study of the progression of NSS during adolescence will provide valuable information about the role of NSS as endophenotypes or biomarkers and about brain development at a stage in which brain maturation has not yet been completed. Methods:  Neurological soft signs were assessed in a sample of 110 first episodes of early-onset psychosis (EOP) and 98 healthy children and adolescents at two different times in a 2-year follow-up period. Results:  Patients with EOP showed more NSS than controls both at baseline (p < .001) and the 2-year follow-up (p < .001). No differences were found in the number of signs among the different diagnostic subgroups (schizophrenia, bipolar disorder, and other psychoses). When we examined the changes in NSS over the follow-up, the reduction of NSS in the patients was greater than the controls for ‘Motor coordination’ (p = .032), ‘Others’ (p < .001), and ‘Total score’ (p < .001) of the NES. Conclusion:  Despite the greater reduction of NSS in patients than in controls along the follow-up, patients still have more neurological signs than healthy controls; therefore, these signs may be considered a trait marker. NSS do not seem to be specific to schizophrenia as they are present in different EOPs.

Sex differences and implications in outcome in children and adolescents at clinical high risk for psychosis / Jordina TOR in Journal of Child Psychology and Psychiatry, 66-10 (October 2025)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 66-10 (October 2025) . - p.1461-1472 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.

The affective dimension of early-onset psychosis and its relationship with suicide / Vanessa SANCHEZ-GISTAU in Journal of Child Psychology and Psychiatry, 56-7 (July 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-7 (July 2015) . - p.747-755 Titre : The affective dimension of early-onset psychosis and its relationship with suicide Type de document : texte imprimé Auteurs : Vanessa SANCHEZ-GISTAU, Auteur ; Inmaculada BAEZA, Auteur ; Celso ARANGO, Auteur ; Ana GONZALEZ-PINTO, Auteur ; Elena DE LA SERNA, Auteur ; Mara PARELLADA, Auteur ; Montserrat GRAELL, Auteur ; Beatriz PAYA, Auteur ; Cloe LLORENTE, Auteur ; Josefina CASTRO-FORNIELES, Auteur Article en page(s) : p.747-755 Langues : Anglais (eng) Mots-clés : Psychosis  suicidality  depression Index. décimale : PER Périodiques Résumé : Background The affective dimension has scarcely been studied in early-onset psychosis. Our aims were to investigate the prevalence and type of affective symptoms in the prodromal and acute phases of early-onset psychosis and to examine their relationship with suicide. We also sought to establish whether the presence of premorbid antecedents or the presence of affective symptoms during the prodromal and acute phase might predict a later diagnosis of bipolar disorder (BP) or schizophrenia (SZ). Method Participants were 95 youths, aged 9–17 years, experiencing a first episode of a psychotic disorder (FEP) according to DSM-IV criteria. Prodromal affective symptoms in the year prior to the onset of full-blown psychosis were assessed by means of the K-SADS. Affective symptoms during the acute episode were evaluated using the Hamilton Depression Rating Scale and the Young Mania Rating Scale. Suicidality was assessed during the acute episode and at 6 and 12 months. Results Half of the patients experienced affective symptoms during the prodrome, with depressive symptoms being the most frequently reported. During the acute episode, 23.2% presented depressive, 41.4% mixed and 18.9% manic symptoms. After logistic regression analysis, only the presence of depressive symptoms was significantly associated with suicidality during the 12 months following the FEP. Neither early premorbid antecedents nor the prevalence or type of affective symptoms during the FEP predicted a diagnosis of BP or SZ at 12 months. However, both depressive and manic prodromal symptoms were associated with a later diagnosis of BP. Conclusions The FEP of both SZ and BP is preceded by an identifiable prodromal phase. Early detection programs should target young people at clinical risk for the extended psychosis phenotype. The high prevalence of affective symptoms during the early phases of psychosis may encourage clinicians to identify and treat them in order to prevent suicide behaviour.
