Neighbor diagnosed. How can I help?

Hello my dear sweet neighbor of the past ten years has just been diagnosed with Parkinson’s. She is in her 60’s, single/lives alone and only retired from working in public health a couple years ago. And because she has been such a wonderful neighbor, I just would love any tips on how my husband and I can help or offer support. Any small gadgets/tools or gifts that you think are essential. Any books she should read? Anything that helped you find comfort when you/your loved one first were diagnosed. Thank you so much for any help and time you give!
