Establishing a Clinical Database and Biobank for Schizophrenia：A Cohort Study

Participants will undergo follow-up for a minimum of one year, with regular clinical data collection at baseline, half a month, 1st month, 3rd months, 6th months, 9th months and 12th months. Baseline assessments will include demographic information, medical history, and previous medication use. For participants on antipsychotics at baseline, the Simpson-Angus Scale for extrapyramidal symptoms(SAS) will also be administered. At baseline and each follow-up, data on current medication, physical examination, anthropometry, ECG, EEG, psychiatric scales (PANSS, CGI, GAF, PSP, SAS, TESS, MMAS-8), the MATRICS Consensus Cognitive Battery, and laboratory tests (blood routine, liver and renal function, lipids, fasting glucose, fasting insulin, HbA1c) will be obtained, alongside fMRI, eye movement, and fNIRS measures. Blood samples will be collected and stored for mechanistic investigations.

Volunteers will undergo assessments, including SCID scale, SCL-90, Chinese Perceived Stress Scale(CPSS), the Measurement and Treatment Research to Improve Cognition in Schizophrenia(MATRICS) Consensus Cognitive Battery, blood test(blood routine, liver function, renal function, blood lipids, fasting blood glucose, fasting serum insulin, fasting blood glycosylated hemoglobin), as well as functional MRI, eye movement, functional near-infrared spectroscope and electroencephalogram. Blood samples for exploring difference between patients and healthy people will be collected and stored.
