Study: Schizophrenia Is 8 Diseases

September 16, 2014

(CNN) – What we know — and psychiatrists have diagnosed for decades — as schizophrenia may really be eight separate diseases, research published in The American Journal of Psychiatry suggests. Scientists at Washington University in St. Louis analyzed the DNA of more than 4,000 people with schizophrenia. They matched any gene variations they found in the DNA with study participants’ individual symptoms. In doing so, they found several “gene clusters” that appear to cause eight distinct classes of schizophrenia, according to a statement from the university.
