And that's primarily because depression has mainly the younger folks at a time when they can be very productive as well, which then cut down quite a bit in terms of productivity and this is where typically the socio-economic measures for burden comes from.

So now where quarter of the whole depressed population is adequately treated at one point and out of those only a part of those do respond to the treatment.
