简要总结
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.
详细描述
Cognitive deficits (DC) are considered one of the essential features in psychotic disorders and occur throughout the course of the disease. Recent meta-analyses have shown that cognitive remediation therapy can reduce DCs in basic cognitive processes such as attention, memory, and problem solving and can have an impact on social functioning.
The aim of this study is to evaluate the effectiveness of a computerized cognitive remediation intervention in cognitive and functional improvement in patients with a first psychotic episode that is psychopathologically stable but presents cognitive impairment.
The hypotheses that are raised are:
-
In relation to the cognitive field. Participants in the computerized cognitive remediation therapy + treatment as usual (CCRT) group versus the participants in the treatment as usual (TAU) group are expected to improve in (evaluated by MATRICS):
-
Verbal memory
-
Visual attention
-
Executive function
-
Social cognition
-
In relation to other symptoms. Participants in the CCRT group versus the participants in the TAU group are expected to:
