Of course, but at least Picard was still aware of who he was, he didn't "lose" his memories or "time" or anything like that. I didn't get that with Seven, I really had the impression she regressed to the 7 or 8 year old Annika she was when she was first assimilated.
Then again... maybe that's just who she is now, a child in an adult body having to grow up again. Would be plausible considering her cortical implants are gone as well (and who knows how much of her personality/memories were stored there).
Yes... who knows, indeed?
