I think, though, a distinction needs to be made. Personality disorders do not lack intent; that is, a person with a personality disorder chooses to continue their behavior. For a neurological disorder, this would be nearly impossible. A middle ground, mental disorder, is a bit less distinct.Kukul said:So what? I didn't choose to be messed up, either.
For a person with autism, their neurology is physically impaired. It is unlikely they can simply elect to overcome their social inhibitions, for example.
For a person with social anxiety -- can they simply choose to overcome said social inhibitions? I would say some yes, and some no. But that is the limitation of the DSM -- mental disorders reside in a grey area where the difference between choice and biology is still indistinct with our medical knowledge.
For a person with borderline personality disorder (and, bear in mind, nothing else, as neurological and mental disorders can present with personality disorders as well), they are equipped to understand their actions, are able to anticipate reactions to their actions, and are capable of understanding beforehand the likely consequences of their actions. They simply, basically, refuse to acknowledge, either through plain denial or a stubborn refusal to accept anything but their own will, their condition, or prefer their condition to the work required to improve said condition or over improvement at all. The only reason this gets to be called a disorder, really, is that a disorder is loosely defined as any state or situation that results in a failure for a person to maintain a reasonable state of existence -- which is why, for example, the DSM-IV includes guidelines for depression that include one or more debilitating states or events that meet a criterion for "disorder."
Frankly, I think "personality disorder" is a bit of a misnomer, since it's only really a disorder for everyone around the person, and not a disorder FOR the person until that person acknowledges it as such -- although some obvious criteria can lead to legitimate diagnoses of "disorder." If your continued negative actions result in you being out in the street with no food, for example.
Not to piss anyone off, but I look forward to a day when the science of the brain catches up to the point where we can definitively pinpoint the causes of so-called disorders. Either we'll find out that many of us who believe we are disordered are simply hiding from our own bad choices, or we'll find out that neurology is everything and answer a lot of questions about things like choice, the soul, etc.
If you have a personality disorder alone, though, you choose to continue to have it, if you even believe you really have it, diagnosis from a medical professional notwithstanding.
