Indeed, not to mention the cognitive issues brought on by depression itself. I am taking notes, which I was already used to because my memory was impaired by the depression. The extent of things I'm forgetting, like others have mentioned, is more or less "did I see that movie already" or "did I say/do that already." It's not really a big deal to me so far, given that it's limited to the ECT time period, should be temporary, and it's hard to distinguish from the symptoms I already had. I can usually recover most of my memories anyway if I run through the "check list" in my head or apply some logical reasoning. If it doesn't get worse than this, then it's totally worth it in my opinion. Honestly I can't even really tell whether the memory issues are really due to the ECT treatment, or due to going under general anaesthesia multiple times a week, which is admittedly pretty intense.
