I have mood swings and I also have outbursts that are way out of line with the situation.

I can hear myself saying things that can never be unsaid, but I am powerless to stop myself.

I don't have the mood swings, but I read it is a part of PD.

When I am emotionally struggling, I play guitar. Drills, lessons, songs, solos, instrumentals, whatever comes to mind. In that moment it is just me and the guitar

Mood swings can definitely occur with all the parkinsonisms as well as changes in personality. Some days I’m sweet as sugar, and others I’m a firebrand. And then there are days like today…..

No I don't but talk to your Dr maybe meds can help
