I was wondering if another possible use might be to lift an Imperius 
Curse? We see cases in the books where people fight it off, and cases 
where the victims are freed by the death of the caster (maybe-this 
defense was used by some DEs who claimed to have been Imperio'd by 
LV). But we have not been shown a counter-curse, and it would seem 
that once the curse has been successfully applied a mere "Stupefy". 
(Since, for example, Crouch Jr. remains Imperiused for long periods, 
during which his father doubtless sleeps...)
