Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to investigate the efficacy of neuroscience-guided computerized cognitive training exercises on the remediation of cognitive deficits and symptoms associated with recent-onset schizophrenia and to examine the influence of subject characteristics, brain structure and function, and pharmacotherapy on the response to remediation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Participation in this study will last approximately 12 months and will involve individuals with recent-onset schizophrenia. All participants will undergo baseline assessments that will include an interview, written tests, blood draws, and electroencephalogram (EEG) and magnetic resonance imaging (MRI) scans. Participants will then be assigned randomly to receive treatment with either computerized neuroadaptive cognitive training or commercially available computer games. Participants will be asked to complete 60-minute sessions of their assigned treatments 5 days per week for 8 weeks. For participants receiving cognitive training, exercises will focus on improving speed and accuracy in the perception of and response to verbal and visuospatial targets. The 8 weeks of treatment will focus on targeted cognitive training (TCT). Participants assigned to practice computer games will play standard commercially available games, with no targeted response.

Participants will repeat baseline assessments after the computer training and Month 6 of follow-up. The EEG and MRI will be repeated only at post training assessment visit. There will be a blood draw at Week 2 of treatment as well. After the Month 6 assessment, participants in the control condition will be offered an opportunity to complete an additional 8 weeks of computer training with different modules.

Computer games

Intervention Type BEHAVIORAL

The control treatment involves commercially available computer games that participants will practice 1 hour per day, 5 days per week, for 16 weeks.

2

Participants will receive targeted cognitive training with neuroplasticity-based software created by Posit Science Corporation.

Group Type EXPERIMENTAL

Neuroadaptive cognitive training

Intervention Type BEHAVIORAL

Neuroadaptive cognitive training includes cognitive remediation exercises that participants will practice 1 hour per day, 5 days per week, for 8 weeks. The exercises are specifically designed to improve speed and accuracy in the perception of and response to verbal targets. The treatment will focus on TCT.

Intervention Type BEHAVIORAL

Neuroadaptive cognitive training includes cognitive remediation exercises that participants will practice 1 hour per day, 5 days per week, for 8 weeks. The exercises are specifically designed to improve speed and accuracy in the perception of and response to verbal targets. The treatment will focus on TCT.
