pre existing conditions rule is covered then I have found companies to be v. helpful.

Keep them in the loop, and I found UK insurance providers to be most helpful. When you have a positive dx of PD, they have more on their plate chasing fraudulent "bad backs", "headaches" and "depression" claims that take up 90% of their time.

PD is serious and life changing, you know that and they know that as well.
