What sister in law?

We were at Austinmer Beach the other day when I saw Mum's sister in law and her family. As I headed over to talk to them, Mum said "I don't want to talk to those people, I don't know them." I said, "It's your sister in law, Pat. You know Pat, Dad's sister!" She said "No I don't know any Pat, I didn't know I had a sister in law.'

This is very worrying. It's the first time she hasn't recognized someone.

Over the past 4 months or so, she has got her two cats mixed up. She'd pick up a cat and say, "What's this cat's name? I forget." So I had to start telling her the cats' names. Then she'd keep asking, "How many cats have I got?"

On the other hand she remembers the most amazing things and would blitz the Coledale Hospital's Trivia Quiz every time.
