Dear Jan -
PLEASE do not drop out without talking to your psychiatrist. It is my understanding that unless ketamine is used as the general anesthetic, a
temporary loss in short term memory almost always "goes with the territory" of RUL ECT, but one recovers from it after 4 - 6 weeks. (This is in marked distiction to BL ECT, where there can be permanent retrograde amnesia.)
Frankly, I'm somewhat surprized that your practitioner didn't mention this up front. But seriously, it is not to worry.
Mike
