简要总结
Cognitive remediation (CR) and aerobic exercise have separately shown promising results in schizophrenia cognitive improvement, despite this, the impact in improving functionality is still limited. Aerobic exercise increases Brain Derived Neurotrophic Factor (BDNF) levels, promoting neuronal and cognitive plasticity, which can maximize the impacts of CR. The aim of this randomized controlled trial is to study the efficacy of a 3-month intensive program that combines CR plus physical exercise comparing it to cognitive remediation plus a control activity.
详细描述
Cognitive remediation (CR) and physical exercise have separately shown promising results in schizophrenia cognitive improvement, despite this, the impact in improving functionality is still limited. Physical exercise increases Brain Derived Neurotrophic Factor (BDNF) levels, promoting neuronal and cognitive plasticity, which can maximize the impact of CR. The aim of this project is to study the efficacy of an intensive program (3 months) that combines CR and physical exercise by a randomized controlled trial where 74 patients with chronic schizophrenia will be randomized to two groups: 1) CR plus physical exercise; 2) CR plus control activity (health promotion). Primary outcome measures will be cognitive performance, functional outcome, negative symptoms and BDNF levels. Measures will be blindly assessed at baseline, at 3 months follow up and at 15 months follow up. The investigators expect that: i) the CR plus physical exercise will be superior to CR plus control activity in improving cognition, functional outcome, negative symptoms and in increasing BDNF levels in the short and medium term (3 and 15 months); ii) changes in BDNF levels after the CR plus physical exercise will be an adequate biomarker of the cognitive improvement obtained with this treatment.
