NEURO-COGS: Neurometabolic Mechanisms of Cognitive Training in Schizophrenia

Краткое описание

This study will examine brain metabolic and excitatory/inhibitory mechanisms related to cognitive and visual functioning in adults with schizophrenia and healthy control participants. Participants will complete behavioral assessments, cognitive testing, electroencephalography, magnetic resonance imaging, and magnetic resonance spectroscopy assessments. After baseline assessments, participants will be randomly assigned to one of two computerized cognitive training programs: perceptual discrimination training or cognitive control training. Each training program will include approximately 10 hours of training over 2 to 6 weeks. The study will evaluate changes in cognitive and visual task performance, EEG measures, and brain metabolite concentrations before and after cognitive training. Some participants may also complete optional extended baseline assessments before cognitive training.
