I hope you'll let me weigh in on this, though not suffering with this disorder...

Other than the use of the MPD rather than the DID (as we do in USA) the information appears to be accurate. Brain waves, blood pressure, allergies... all can be different (though they don't have to be) with the various aspects of a person. Very interesting isn't it? I'd like for the naysayers to try and control THEIR bodies that way, said naysayers who think y'all are "faking" it... if you could control your bodies so powerfully on purpose, I doubt any of you would be "disordered" in any way!
