New insights into biological underpinnings of schizophrenia

Researchers have implicated 10 new genes in the development of schizophrenia using a method called whole exome sequencing, the analysis of the portion of DNA that codes for proteins. A global consortium of schizophrenia research teams incorporated genetic data from over 125,000 people to gain deeper insights into the genetic underpinnings of schizophrenia.

Researchers found that PTSD affects infection risks for men and women differently, having, for example, more of an effect on a woman's risk of urinary tract infection and a man's risk of skin infection.

The researchers say that tranexamic acid (TXA), a drug that prevents bleeding into the brain by inhibiting blood clot breakdown, has the potential to save hundreds of thousands of lives.
