If doctors who have examined him are confused, I don't think we are going to be able to come up with valid explanations.
What kind of doctors have seen Dad? (Internist, GP, Psychiatrist, what?) Have they suggested further tests? If you are looking for second opinions, I suggest a behavioral neurologist or a geriatric psychiatrist.
Good luck to your whole family!
Any vascular or heart disease?
My Dad use to write Code for computer programs, and as he aged he would start forgetting passwords and where he had kept the passwords for safe keeping. Eventually he stopped using his computer.
When it comes to bus electronic arrival boards, sometimes it is easier for an elder to use a regular clock which has hands. Usually that is ingrained into their minds since childhood. I know for myself, I refer a hand clock compared to a digital readout.
