What is mental illness? New research says Schizophrenia is eight different diseases, not one

Schizophrenia appears to be a group of eight distinct disorders, so says new research published online Sept. 15 in the American Journal of Psychiatry, a publication of the American Psychiatric Association: “schizophrenia is not a single disease, but a group of eight distinct disorders, each caused by changes in clusters of genes that lead to different sets of symptoms.” After comparing “the DNA of 4,200 people with schizophrenia to that of 3,800 healthy people,” researchers also “found that certain genetic profiles matched particular symptoms.” The research was funded by the National Institutes of Health. Liz Szabo, commented on the findings in USA TODAY, September 15, 2014, noting that Schizophrenia is eight different diseases, not one. This is an interesting article that highlights how new research may reveal ways to better identify the problem and lead to better therapies.
