thyroid problems often accompany pd and so do hormones or lack of. you might want to add them. also i used to take little green pills after being diagnosed with Irritable Bowel syndrome.

this was before pd diagnosis and very shortly before motor pd symptoms emerged,
therefore i was on synthroid and prem forgot the rest of the word but it was a combination of estrogen and another hormone due to early menopause.

my hormone system is shutting down. its' significant and understudied.
