I can’t tear myself away from that story on awakening PVS patients with a sleeping pill… Before I finally pack my bags for the night let me direct you to https://blog.bioethics.net/. These guys blogged about that story back in May, when it was really news. They are getting it wrong when calling PVS patients “people who are basically dead” (a weird mistake for professional bioethicists to make!), but their piece together with the comments it elicited is still worth reading. Certainly the short paper in Neurorehabilitation needs to be followed up with a large-scale study.
