I am diagnosed as schizoaffective and I had treatment three years ago. I had 8 sessions and it improved my concentration and helped my morning depression. I only got short term memory loss first time and of course it came back.
It has given me fever dreams which I still have to this day but I get back to sleep so it isn't a huge problem.
I was scared witless before first session but the anaesthetic kicked in right away. I don't think my morning melancholia could have been treated any other way. So for depression I would say it is worth considering.
