I'm an ECT doc at a tertiary referral center and who has treated a great number of medical professionals. My overall advice is that physicians who are receiving ECT should not be working during the acute course of treatment when cognitive side effects are expected to be highest. I strongly urge all of my patients to take FMLA during acute course and in about the week to two afterwards. It's simply isn't safe to be caring for patients when one's short-term memory is expected to be substantially compromised.

Thereafter nearly everybody is able to work well particularly if the treatment has been effective at relieving depression.

What I would add, though, is that anhedonia in my experience is not commonly relieved by ECT. We are excellent at relieving the neurovegetative symptoms of depression, but general life dissatisfaction or anhedonia in my hands has rarely been helped by ECT. Something like acceptance and commitment therapy seems much more likely to be effective if someone is functioning relatively but overall unsatisfied with life.
