Filter by:Background: Presence of a series of typical physical symptoms is an enduring and functionally relevant feature of early-onset schizophrenia (EOS). Psychotherapy improves clinical symptoms in adults with schizophrenia, although data in adolescents with EOS remain scarce. The purpose of this study is to examine the efficacy of the adapted group psychotherapy in improving clinical symptoms from a perspective of neuroimaging in a sample of symptomatically stable adolescents with EOS. Methods: Investigators conducted a double-blind randomized controlled trial using multidomain, adaptive, group psychotherapy in 28 EOS patients, who were randomly allocated into either training (group psychotherapy) or active control (health education) groups. Data of diffusion tensor imaging, and clinical symptoms were obtained at baseline and after an average of 2 hours/day, 2 days/week for 4 weeks of intervention.
Cognitive deficits (CD) are considered one of the essential characteristics in psychotic disorders and occur throughout the course of the disease, being a key characteristic in the evolution of the disease and in the functionality and prognosis of patients. Intervening in the early stages of the disease and specifically in adolescence, a period of high brain plasticity can reduce disabilities in adulthood associated with early-onset psychosis. The objective of this study is to assess the efficacy of cognitive rehabilitation therapy in adolescents with a first psychotic episode, comparing two groups of these patients: a first group (CCRT) will carry out 40 sessions of a computerized cognitive remediation therapy with the usual treatment too, and a second group will perform only the usual treatment (TAU). The main hypothesis is that the CCRT group will present a significant improvement in verbal memory, visual attention, executive function, and social cognition and will present better global functioning compared to the TAU group.
The purpose of this study is to examine the nature of reward processing dysfunctions in schizophrenia using neuroimaging techniques that capture in vivo brain functioning, such as EEG and fMRI.
In this study,investigators will recruit 100 DSM-Ⅴdefined EOS Han patients, older than 7 years old and onset of illness before 17 years old, and all EOS patients will receive a 8-week systematic olanzepine titration treatment and a battery of assessments of treatment effect and safety. Blood olanzepine plasma concentration will be tested regularly and genotyping of 8 polymorphisms of 5-HTR2A, DRD2 and COMT genes will be conducted by Polymerase Chain Reaction （PCR）, Restriction Fragment Length Polymorphism (RFLP) and TaqMan probes genotyping technology. The aim of the study is to explore the predictive factors on olanzepine treatment response in EOS, which can guide the individualized treatment and improve the cure rate of EOS in clinical setting.
