We know now, and have known for probably over a decade, that most mental illnesses begin in early childhood, so intervening early and aggressively gives us the best outcomes, whether it's in the childhood years or as young adults and beyond. The investment has to happen early. We need to get upstream of this problem. Once we get to older teenage years or young adults, we've lost that window of opportunity. We haven't lost it completely, but it's going to cost a lot more. You're going to have impacts on the justice system at that point, the welfare system. Early intervention really is the key piece, as we've pointed out earlier.
With regard to overall strategies, I'll let Dr. Lipman chime in. However, I would again say that's not an easy answer. You need the evidence to see where your best opportunities are. I think a national approach to that is important.
