It is, or at least was, a controversial treatment for anxiety. And my grandma was drug seeking. She just wanted to be bombed out of her mind on Xanax, so I can even see looking for other treatment options out of desperation because nothing worked the way she wanted and they wouldn’t give her enough Xanax.
I get it. It was just hard to watch her after her treatments. At first the memories came back, but eventually they didn’t.
But that’s just my experience. I’m not going to argue with medical science because even if future science shows mistakes were made, it’s not like I have the knowledge or experience to do better. But science grows by being challenged and proving itself or being proven wrong. I’m okay with it being challenged by actual professionals - not by Scientologists.
