I have learned much about Parkinson's disease (PD) from a disability perspective. It is interesting to learn how visual stimuli can affect someone with PD, how such stimulus can be attenuated, and what accommodations might work for someone with an advanced case of this neurological disease.
Whether or not HRC has PD is not so much the issue; the deceptions about her medical condition and ability to perform the highly stressful duties of a U.S. Presidency is very much a concern. If her campaign is a preview of performance to come given her many medical issues (concussions, transverse sinus thrombosis (brain clots), ataxia, and possibly a neurological disorder), then who in good conscious would vote to put her into such a compromising position? How would the Armed Services respond to having a Commander In Chief who is neurologically compromised?
Unless this is just a craven pursuit of power regardless of the costs to a nation...
