The current study aims to evaluate the impacts of yoga and aerobic exercise on neuro-cognitive function, symptoms and brain changes in early psychosis. A total of 120 female subjects who aging from 18-55 years old, and diagnosed with psychotic disorders within the past 5 years, will be randomized into 3 groups: 1) yoga therapy, 2) aerobic exercise, and 3) waitlist group as the control. All groups will try to be kept consistent with their medication with no more than 25% change in their entry level dosage for at least six weeks. The primary outcomes of the present study will be neuro-cognitive changes; the secondary outcomes will be changes of brain structure and function.
