I hope you’re well.
In light of the information that you’ve given regarding your mother’s recent diagnosis, I think it would be worth you reading the ‘newly diagnosed’ section on the Parkinson’s website for advice on the help and support that is available to your mother. You can this section here.
We also have an entire section on Levodopa here which you may find useful as it goes into detail about its benefits as well as the risks and side effects associated with the drug. I’m sure you’ll receive a lot of advice from other forum members, however, I think the links above will be a good place for you to start.
I hope you find the above information useful.
All the best and do keep us posted on how you get on.
