Most forms of treatment, in terms of therapy, psychiatric medication, or more invasive options, cease to be effective when they're removed, eventually.
ECT and ketamine, for example, are sometimes found to be effective for O(months) after initial more frequent treatment, while most of the psychiatric meds you run through earlier if you're pursuing that type of treatment take weeks to become effective (or not), weeks to stop, and the beneficial effects often stop much sooner than the side effects after taking them (...if they stop at all, in some cases).
ECT can and often does do lasting damage. It should not be used lightly. But singling out ECT for being a recurring treatment seems unreasonable when the other avenues of treatment, both behavioral and otherwise, have the same caveat.
