"What seems to be affected, if we go by the scene where she brings 
Harry to Hogwarts, is her patronus. The impression I get is that 
while not every wizard/witch is an animagus (in fact, isn't it 
rather rare?), practically any can produce a patronus if they are 
sufficiently skillful. I think the confusion arises from the fact 
that if a witch or wizard is an animagus, their animagus form and 
their patronus are the same animal (a stag, e.g., in the case of 
James Potter)." <snip>


CH3ed:
Tonks' patronus was definitely affected (as Harry and Snape 
witnessed it). And it seems her skills as metamorphmagus 
deteriorated as well since Hermione observed that Tonks couldn't 
change her appearance like she used to. 

I suspect it is harder to become an animagus than to produce a 
patronus, but I think you can learn to do both (even Peter could 
become a rat with the help of James and Sirius). 

 I tend to agree with la Gatta that a person's animagus form and 
patronus are probably the same (can you imagine Peter sending a rat 
patronus after a dementor? ;O) ), but I don't think that is canon. 
The stag patronus belongs to Harry (we have never seen James' 
patronus. It was Harry who cast that stag patronus that drove all 
the dementors away at the end of PoA). And we were told by Lupin 
that James was a stag when he transformed.
