Cohort Description

The study includes 250 patients with first-episode psychosis or bipolar disorder, 250 individuals at high risk for psychosis or bipolar disorder, and 250 healthy controls between 15 to 35 years of age. Subjects will be recruited from Pusan National University Yangsan Hospital. MRI data will be collected using a 3T Siemens Vida MR scanner. Subjects are assessed on a yearly basis after the baseline, 3 months, six months and one year. We would like to develop a model for predicting transition to psychosis and bipolar disorder by using various biological markers, and present a pluripotent diagnostic system covering various mental disorders at the same time in the direction of quantitative psychiatry.
