I had 36 one-hour sessions of rTMS- There is NO memory problems! It simply feels like a woodpecker tapping on your temple. You sit there watching a TV show while...rat-a-tat-tat the magnet zaps your head... It's no big deal and there's no medical problems. The only problem I experienced is it didn't do anything for me. But that's understandable as nothing has worked at all for me, not meds, not ECT, not Ketamine, nothing. It's definitely worth a try if you're miserable.
