My father is 69 and has advanced Parkinson's and I believe Lewy Body Dementia. He has a lot of trouble with his phone, and believes people are going in and changing the numbers. He will look at his recent call list and try to call someone, but hit the wrong button and it will call someone else. No matter how much I try to show him what is actually happening, he does not believe me and believes that my explanation makes no sense. He has a password on his phone, but we had to simplify it because he always forgets. He has aides who help him during the day, and he thinks they are getting into his phone. He will call me throughout the day and then insist he did not call me and someone is doing something. I have gotten him a easy to use phone, but he cannot figure it out and deletes numbers all the time.
Every time I try to give him a rational explanation, he yells at me and tells me I'm wrong. I have also tried to redirect him, but he gets insistent. I will show him the phone and that no numbers are changed, and he then says I delete the evidence or someone else did. Is there anything I can do?
