(CBS) – Researchers have discovered that five major psychiatric disorders share common genetic risk factors.

The largest ever genetic study of pyschiatric illness found autism, attention deficit-hyperactivity disorder, bipolar disorder, major depressive disorder and schizophrenia shared several risk factors.
