A Genetic Family Cohort Study of Bipolar Disorder in Chinese Han Population

This study intends to find out the pathogenic genes of bipolar disorder by collecting the two-phase family of Chinese Han population with the large sample using a family cohort study design, combined with the new generation of high-throughput sequencing technology and Genome-Wide Association Studies (GWAS), Proteomics, bioinformatics analysis, etc., which is expected to be clarified at the genetic level. The pathogenesis of bipolar disorder. At the same time, the investigators will conduct a five-year follow-up of cognitive function, brain function imaging and other major clinical symptoms in patients with bipolar disorder in the core family, and to explore familial bipolar disorder and sporadic biphasic. Differences in the clinical features of the disorder, in order to explore sensitive and specific biomarkers from a multidimensional perspective (cognitive function, brain imaging, genetic features, clinical features, etc.), which may contribute to bipolar disorder in the future. Accurate diagnosis and early identification and prevention have important scientific significance and clinical diagnosis and treatment significance.
