It's true that a patient can't receive involuntary without consent. I was close to receiving an ECT a few years back because I was a minor and it was my parents decision. They've now told me it was a last case scenario, but my onset was at about 14 years old and was extremely severe. With a regular medicine regiment I was able to see what would be in my near future if I didn't start cooperating. All in all a medicine treatment that's maintained could prevent an ECT scenario. Though many have had positive outcomes from it. Sorry for the rant, if you want to talk PM me.
