Electric shock treatment

I really would like to talk to someone who knows about this treatment. I would like to let people consider this scenario (which really happened) to a fellow patient when we were in a facility together. A woman who would have been around 25 to 30 years old and was unwell at the time was given papers for the approval of receiving electric shock treatment. I was sitting next to her out the back where you were allowed to smoke (back in the day) when she asked me to go over the papers with her because she was having trouble comprehending them. I remember going through some of the side effects bit scary chance of heart attack was one of them. I was getting concerned because she was unwell and seemed to be giving the go ahead for this treatment she didn't really understand. She did not have an advocate. Why not? How can someone who is unwell be asked to do this. She had the treatment. She returned in a wheelchair. She had wet herself and her head was lolling down. She was very quiet unresponsive and was definitely not aware what was going on around her. This happened about ten years ago and sometimes makes me wonder about the system. Does anyone know about the protocols for this. Seems disgusting that she didn't have anyone to give her advocacy in a situation like this
