Do clinical characteristics predict the cognitive course in early-onset schizophrenia-spectrum disorders? / Charlotte M. TEIGSET in Journal of Child Psychology and Psychiatry, 59-9 (September 2018)
[article]
Titre : Do clinical characteristics predict the cognitive course in early-onset schizophrenia-spectrum disorders? Type de document : Texte imprimé et/ou numérique Auteurs : Charlotte M. TEIGSET, Auteur ; Christine MOHN, Auteur ; Cathrine BRUNBORG, Auteur ; Monica JUUHL-LANGSETH, Auteur ; Aina HOLMÉN, Auteur ; Bjørn Rishovd RUND, Auteur Article en page(s) : p.1012-1023 Langues : Anglais (eng) Mots-clés : Cognition early-onset schizophrenia suicide attempts general symptoms Index. décimale : PER Périodiques Résumé : Background Being in a period with extensive brain maturation, adolescents with early-onset schizophrenia-spectrum disorders (EOS) provide unique neurodevelopmental data that may contribute to a better understanding of schizophrenia at all ages. Cognitive dysfunction is a central feature of schizophrenia and is more pronounced in EOS than in later onset illness. However, there is limited research on both the long-term course of global cognition in EOS, and how cognition over time is influenced by clinical characteristics during the early illness period. Methods Thirty-one EOS patients and 73 controls (age 12?18) were assessed on clinical variables at baseline (PANSS, duration of untreated psychosis [DUP], hospitalizations, suicide attempts, and remission). Neuropsychological assessments with the MATRICS Consensus Cognitive Battery (MCCB) were conducted at baseline and after both 1 and 2 years, and composite scores of total performances were calculated. The analyses were performed with a linear mixed model. Results The present study found that global cognition followed a stable course over the first years of the disease in EOS, though at a significantly lower level in EOS compared with the controls. We did not detect a relationship between DUP, remission, positive/negative symptoms, and hospitalizations on one hand, and long-term cognition on the other hand, but PANSS-general and suicide attempt history at baseline were identified as risk factors of longitudinal cognitive function. Conclusions Though at different levels, the EOS group and the controls had a similar cognitive course over 2 years. Some baseline characteristics (psychotic symptoms, DUP, remission, and hospitalization) had no influence on cognition within the first 2 years of illness. In contrast, general symptoms and a history of suicide attempts at baseline were more potent risk factors of the cognitive course than the psychotic-specific symptoms, and should, therefore, be subject to specific attention in the evaluation and treatment of patients with early-onset psychosis.
