I don't know how to respond to this other than to say the drugs clearly have an effect on the central nervous system, some effect on SA, RD very likely, and the sleep reduction is symbiotic with an effect on attention deficits one can guess- do not at all seem like a dead end. With folks like Pfizer continuing to slash and burn RD it's anyone's guess if there are willing partners but I think CX-1739 and AMPA deserves a chance.
