Yes, more money should be invested into finding brain-enhancing pharmaceuticals because the effects of brain diseases like dementia and Alzheimer's are devastating on the people that develop them and their families. By investing more resources into this area, the science community could greatly improve the quality of life of millions of people.
The goal of Twenty-First Century humanity is to better ourselves to make life fall into eternal bliss. At least that seems to be the myth. So we should put as much cash as we can into finding the best ways to bathe our brains in chemical enhancement bliss. Then we will be all we can be.
