When you first have ECT you usually have 3 treatments a week for 6 - 9 treatments. Some people stop there but others have maintenance treatments when the ECT "wears off". Right now I call in if I start to go down hill and get a treatment. The last time it was a month between treatments. The time before it had been three weeks.

As for memory loss, I would say minimal and inconsequential things like forgetting that we have a Panera in town. When reminded of something I have forgotten it all comes back. Usually memory loss covers the time just before and after treatments... minutes, to hours to days. I can remember everything around the treatments. ECT has been a positive thing for me.

There are people who have maintenance ECT for years. The woman who played Princess Leia in Star Wars has ECT monthly and has for years.
