Kerry Hodgson received 307 electro-convulsive therapy (ECT) treatments over the course of 10 years. It was supposed to help with her depression. Instead, it wiped out much of her long-term memory.
It's also induce cognitive issue. It takes myself more time to learn things than before I had ECT (I had "only" 5 ECT), which is really frustrating because I wanted to come back to university and I can be as efficient as I want to. Also had the memory loss (came back for me after 2/3 years but I had less ECT).
