There should be way more effective spells for enthralling victims, DPs ruling is that Hearts Ease can't erase trauma, but artificial madness, is exactly the kind of thing mind-healing D&D spells should be most useful for.
I mean Dresden Mind manipulation, seem most like a form of ability drain to me, so a Restoration spell should break the damage the magic has done, though of course the trauma of what you were made to do, while your mind was altered should linger with you, but Dresden Mind manipulation, should work either like that or like a madness curse.
It's not like the reason Dresden mind damage is so hard to undo is conceptual, it's because it's exponentially easier in Dresden to break a mind than to put it back together, so this is one of the places, where D&Ds magic being much better at such things, should mean that it can put it together.
Also remember that DP ruled Heart's Ease, work better on cases such as staring into the Far Realm and being driven mad, than on cases of mundane trauma, and Dresden Mind magic, is more like the Far Realm madness than mundane trauma.
I get D&D magic not being able to erase black magic corruption, I don't agree with it but I get it, black magic leaves a stain on the soul that can't be erased, but mind magic has never been said to corrupt just break, and fixing broken things is something D&D magic excels at.
The thing DP nixed was Heart's ease just removing was mundane mental problems, he hasn't nixed Heart's ease removing magically caused mental problems, and that's exactly what is preventing Dresden mind magic victims from recovering, so with Heart's Ease they should be able to recover with time and help, as while they still have all the memories to keep them traumatized, the damage done by the spells themselves, as opposed to what they were made to do by the spells, has been reversed.
Of course they should still need a long time to recover, but it should be what they were made to do, and how long they were there that matter, not how much their minds were ravaged by magic.
