My Brother has stage 3 Parkinson, along with Addisons and long covid, not a great outlook for a person barely in his 60s, many meds you find others rave about are usually only those almost uniquely for their singular issues.

Battling one issue with one med is fine, battling more than one, well let's say not much hope. My brother's timeline has been reduced by least 15 years due to Addisons.
