MULTIPLE PERSONALITY DISORDER
Multiple personality disorder, or dissociative identity disorder, is a mental condition that’s interesting on many levels. Perhaps most intriguing of all is how some sufferers not only exhibit personality and behavior changes as they switch between their different identities, but some also have measurable physiological variations between each persona. For instance, one of a patient’s personalities may need eyeglasses and another won’t. Or, one identity might be diabetic and another will have perfect health. In such cases, it isn’t simply a matter of the patients thinking they need eyeglasses or insulin, their bodies actually go through legitimate alterations, such as differences in intraocular pressure or blood sugar levels.
