I went through a very similar situation a few months ago. I had never thought about disability until the reality was thrust upon me by two converging factors: One -- the results of a complete neuropsychological workup, which were conveyed to me together with the information that some of my ratings and scorings looked like a person's who could readily qualify for disability; and, two -- the combination of PD and Type I diabetes became overwhelming, the PD making it very difficult to control sugar levels, with repeated, disastrous insulin reactions. I simply had, like you, to go on STD; but I did so w/full expectations of returning on at least a 60% basis, plus moonlighting to make up the difference. Once out on STD for a couple of months, both the improved health situation and the confirmations of the neuropsych workup resultls, however, made me start to feel you reservations about returning to the regular workaday situation on any basis, i.e. to recognize that I had no place being in the full time workplace anymore. So, my advice would be to talk with your doctor (s) about it; possibly get yourself a neuropsych. eval, or do whatever you need to do to honestly assess your fitness for sustained working, and do what those kinds of information suggest. I'm now on LTD, working as a consultant 3-5 hours/wk, and plan to submit a claim to social security for disability by month's end. John Bachman
