MAPS: Query: MPD and dissociative anaesthetics

["jeff" <eassonj@xxxxxxxxxxxxxx>]

in my psychology course today i learned about MPD (multiple 
personality disorder).  supposedly, these people have different 
vitals (eg heart rate, blood pressure, etc) and sometimes can even 
write with different hands with the different personalities.

i was told that the personalities only exist one at a time ... in 
other words, two can't be "out" at the same time.

what would happen to these people (if anything) when given a 
dissociative (like ketamine or pcp)?  since they're naturally 
dissociative i wonder about this ... could this be a cure ... or at 
least a treatment?

thanx in advance
