I must align with the "Can't" faction. PD is, as was pointed out earlier, just not a disease that can be cured. At least not by anyone but the patients themselves. I have come to see PD as being a disorder very much like anxiety. Doctors don't cure anxiety. They can only mask its symptoms.
The child may be, through exposure in utero, be born anxious. But a larger number are born with a genetic makeup that makes them vulnerable to the environmental factors. Years go by before the stresses of life send the anxious patient seeking help. That usually brings a pill that masks the symptoms but little more.
Meanwhile, beneath the surface, anxiety has been taking a toll on the heart but that will not be a factor for years. For now, the increasing anxiety takes a toll. The home becomes both refuge and prison. The effort to maintain the status quo becomes harder and harder, and panic attacks lurk in the shadows. At some point the cardiac damage begins to be felt and the world begins to close in.
This blending of genetics, environment, life events, personality, social support, systems failure, and the onslaught of physical degeneration combined with an absence of support in the society leads to greater and greater cardiac damage. It becomes harder and harder to do the simplest task....
That's what PD is. I don't think there is a name for it. Like a tar ball on Pensacola Beach, we are the cost of certain decisions made before we were born about the kind of society we would have. Some major changes must be made to the society to prevent new cases and we existing ones just need a quiet place to fish.
