Welcome Leah..I have been on SSDI for 2 yrs..I was dx with pd in 2004..I hired a disability attorney from the git go, and its important to have all your medical documentation in order..If you have a dx of pd related depression it will work in your benefit to push your claim through, or any other disabling illness plus Parkinsons..If you have depression see a psychiatrist..(if you havent already)..and get documentation

Lawyers usually work on a precentage of the settlement..Mine requested 25%, but only if the claim went through the appeals process..My claim went right through on the first shot, so the lawyer didnt charge me anything
