From the summary (no, I didn't read the article): "Currently, the best of those established treatment options can only improve symptoms in 60 to 70 percent of patients" and " the drug had completely erased all traces of symptoms in two-thirds of PTSD patients." To me, the 60 to 70 percent sounds very close to the two-thirds of patients (roughly 66.667%). So, this is better how? I did see in the summary that this drug is reaching some patients who were not helped by other therapy (perhaps part of the 30-40 percent?), so that is a good thing, but the rate of help is not better. What are the (projected) long-term side-effects? Is it worth the long-term costs?
