There seems to be an on slot of new information making claims to be able to cure this difficult condition. It is a terrible problem and the victims seem to be the family and friends who care about the person suffering. They are the ones who try to maintain their affection and still not lose their tempers when the patient is demanding and not reasonable in what they believe.
I hope they create a solution and soon. It is heartrending to watch the memory loos in someone who was a very vital personality.
