Rebirth... is Voldemort disadvantaged?

I discovered someting in my Mythology book last year, which had to do 
with cauldrons of rebirth. 

Dead soldiers in Celtic Myth were put into a cauldrons such as the 
Bran's Cauldron of Rebirth, which was big enough to fit a full grown 
man in. Then they were returned back to life. 

However, there was a disadvantage when this occured. These soldiers 
would never talk again.

So this got me thinking that some sort of disadvantage had occured to 
Voldemort as a consequence of his rebirth... It might have to do with 
Harry's blood... Or what if the missing finger on the arm that 
Wormtail sacraficed, proved to have some sort of effect in Voldemort 
in the long term?
