Yeah this story was on HN before a few weeks ago and I raised similar - it’s nuts to give that to someone who probably doesn’t have the mental state to be able to comprehend what is going on. Don’t understand how it is possibly ethical to do.

Especially with the effects being temporary - can you imagine how awful it must be to regain lucidity outside of your control and then lose it again for the sake of an experiment like this? Awful experiment.

I would imagine the losing it again part is typically somewhat similar to how someone remembers a surgery under anesthesia -- they don't.

What an interesting take. I was imagining how precious one last conversation with a loved one would be.

Yeah well I was imagining how medical ethics work with respect to putting patients through unnecessary suffering. Temporarily restoring someone’s lucidity with the knowledge they will lose it again (having already suffered the progression of the disease the first time) is more helpful to you than it is to them
