Hello
@Marie A and welcome to Talking Point.
Its always overwhelming when you first get the diagnosis and it feels a steep learning curve. Do remember, though, that nothing will change over night - your dad is still the same person that he was yesterday. Change will come, but you will adapt. Not everyone with dementia will have the same symptoms and your dad may not forget you at all. In her last year mum could not remember my name, and relationships were a bit tricky (sometimes I was her daughter, sometimes I was her mum or her sister, or sometimes her aunt), but she always knew who I
was and her face would light up when she saw me.
The best things that you can do is persuade your dad into getting the legal stuff sorted - it will make life so much easier later on if your dad has organised POA (both finances and health & welfare) and if he has made his will. These things need to be done early before they lose capacity
One of the things that I did early on was ask mum about her family history, quizzed her about the name of family members and got her to tell me the old family stories - I wrote them all down. She could still tell about them accurately and now she has passed away my daughter is researching her family tree. I dont know if something like that would appeal to you, but mum enjoyed telling me about them. If I had left it another year or two, she would not have been able to tell me.
