My dad is still being diagnosed and I’m thinking it will be good to try and introduce some activity that uses his brain and keeps him engaged. Over the last couple of days he seems to have perked up and I believe it is down to the fact that he has been doing a few jobs around the house using his brain to do this and he hasn’t done that for years. Don’t know what sparked it off but long may it last. Can you please suggest any good exercises or puzzles etc. Is there a book of suitable mental challenges for him. Thanks just trying to do as much as possible to keep this upward trend going for him.
