Earlier today, we reported that NIMH-funded researchers at three different genetic research institutes from around the world collaborated and published three new studies yesterday in the journal, Nature, that suggested a true breakthrough in our understanding of schizophrenia and bipolar disorder. And to think that just earlier this week, I was dismissing the largely inconclusive findings of genetics research in mental illness.

One of the researchers commented on the findings: “There was substantial overlap in the genetic risk for schizophrenia and bipolar disorder that was specific to mental disorders. We saw no association between the suspect gene variants and half a dozen common non-psychiatric disorders.” This is an important discovery — that some of the roots of schizophrenia and bipolar disorder may be very similar. This may also begin to partially explain why drugs — atypical antipsychotics — developed for schizophrenia also appear to work for bipolar disorder.
