I disagree that "depression is as biological as cancer and heart disease" due to the fact of etiology. While it does spring up out of the blue in many cases, for the most part depression appears to be triggered by complex life circumstances. That is not say that it is not a real disease state with a discrete biological basis. It should just be kept in mind that often the most salient things involved in getting someone depressed and getting them out of depression are not biomedical. It's possible that this is a mostly rhetorical statement by the NIMH head, but I've been disappointed the attitude I see a lot of researchers take towards depression, like it's solely the result of bad gene expression or bad brain connectivity.
