Hi @shalfbeast, we hope you’re doing well.
While there isn’t a strict age, people who develop Parkinson’s under the age of 50 are considered to have young onset Parkinson’s.
We have a page about this here: Young onset Parkinson's | Parkinson's UK
If there’s anything you’d like to ask, please remember we’re here on freephone 0808 800 0303 and always happy to talk things through.
Sending our warmest wishes
The Parkinson’s UK Moderation Team
