Some people are resistant to depression and anhedonia, or lack of pleasure, even when exposed to chronic stress. To measure susceptibility to … Read more

Comparative genetic architectures of schizophrenia in East Asian and European populations

As we all know, schizophrenia is a debilitating psychiatric disorder with prevalence of about ~1% lifetime risk across different populations. However, previously literatures mainly reported in European populations and the results remained ungeneralizable. The present study has explored the biological insights of schizophrenia in the largest sample size of East Asian populations up to now. … Read more
