A warm welcome to the forum.
I’m sorry to hear about your mother’s deteriorating health. We have a section on the Parkinson’s UK website with information on support for family and friends which I think will be useful to you. We also have a lot of information on stem cell research, here.
Lastly, our helpline and local advisers can also offer support to you and your mother. If you contact them on 0808 800 0303, one of our trained advisers can provide more information and advice on your situation.
I hope the above information has been useful.
