Hi and welcome to our forum, @Shaunb. Your wife is very lucky to have you at her side. You’ll find our members a very friendly lot and many have been where you now, waiting to find out what’s happening.
Is your appointment with a Parkinson’s specialist and do you have a date yet? While it’s hard to wait, only they can make a diagnosis, of course. However, we do have a page that might help you here: Do I have Parkinson's? | Parkinson's UK. Please explore the rest of our site too. There’s even some great information for carers like yourself. It’s a demanding but rewarding role.
While you’re waiting, I hope that you’ll get some answers from others. We also have advisers who can talk to you on your Infoline: 0808 800 0303. Please do get in touch if you need to.
