I myself don't have parkinsons, my husband does. Lawrence was in Vietnam and exposed to agent orange. This gave him a double dose of parkinsons because he also got it hereditary. I have one concern, there are times that his whole body becomes unresponsive and this will last up to three hours, this is not a typical parkinsons freeze. The Dr. doesn't have a name for it. I have talked to other people who have family members that do the same thing, and they don't know what it's called. Do you have any ideas?
