They can't ramp things up that quickly... But we need to insist that this is not enough, eg aim to increase by another $10-15 million each year over the next few years.
I think they can go faster than increasing to $15m - thought I'm not sure what would be feasible. Certainly I think $250m in one year is unrealistic, and even if the NIH set that as a budget I don't think there would be anything like enough quality applications to spend the money. But given the years of neglect, I don't think this is good enough as a start.
Maybe $25m, a fivefold increase on historic levels, would have been a decent downpayment. But given we suddenly have a whole load of NIH institutes suddenly 'taking this seriously' - implying a lot more groups to pay into the pot - I can't see the $15m as anything but disappointing, although I do recognise it is the first serious increase in (forever?). Maybe it will go continue to ramp up at a decent rate in the next few years. If it's $93m for MS (I'd thought it was higher) that would do as a medium-term goal, and would transform the field.
I'm a little sceptical about settig a target so high that the NIH won't take it seriously, even if it goes down well with patients generally. Though of course I'd love to see the NIH spend $250m a year.
There will never be an ideal, exact figure, I'm thinking aloud here on what would be reasonable and achievable.
