So sad. Family member (in-law) received ECT for naught. Never the same again. And in the end it turned out that extra nutrition was probably all that was needed since this was right after childbirth. In retrospect seems barbaric. Lifesaver for some, but they don't know who, do they?

You have some good advice here in other posts. Treat like brain damage and get occupational therapy. Get plenty of sleep. Lots of fluids. Good nutrition. Maybe take fish oil. And choline. And whatever else helps brain function.
