After the KISS

Has it ever been mentioned in canon what happens to the witch or 
wizard who has been kissed by a Dementor? I know that the soul is 
kissed, but does the witch remain alive? Can this witch then function 
as a magic person? So you think s/he can talk/walk/so magic after 
being kissed, or do they become vegetables? [Are they taken to St. 
Mungo's and killed, like pulling the plug on someone who is alive 
only by virtue of respirator?]
It is dreadful to be KISSED as I gather from canon, but can one go 
back and learn about magic? Become a magic person again?
Any thoughts?
