10 weeks is a long time for anyone to be in hospital, it must be really challenging for you all. Have you had any support or contact with your local social services? They may be able to help. You can also get in touch with your local Parkinson's adviser who will be able to talk you through some next steps.
If you'd like to read about home care and care options we do have a page on our website at https://www.parkinsons.org.uk/information-and-support/home-care-and-care-homes. But in this case you might find it useful to speak to someone directly, you can do this by calling our helpline on 0808 800 0303. Our helpline is for everyone affected by Parkinson's, our advisers support to family and friends too.
Let me know what you think of the above and if I can do anything else.
