I do not have PD (my motherinlaw does) but I am also affected by flickering lights, especially red or amber colored. I have epilepsy and too much flickering light can cause me to seizure. One time my husband had me do a whole bunch of work on a pc with an amber screen. After about 8 hours straight on the computer I had a seizure that night. Something I hadn't done in years. However I have worked on a regular pc with a black and white screen and with a color screen for the same amount of time and never had any problems. So I strongly agree that lights do affect a person neurologically.
