Kate said she had to initially think about the logistics of bringing Derek home and having to care for him 24/7, but when he came through the door, it was an emotional moment for the entire family.
She recalled: “He definitely knows he’s home, it’s a huge thing.
“There were periods where I didn’t know if he knew who I was, and we would be caring for somebody who was effectively a stranger, which would be terrifying for him and strange for us.
“He definitely knows who I am, he definitely knows he’s home. He also can’t access the ability to say things, it’s a really strange place he’s in.
“Sometimes he can respond to extraordinary things, really specific things – he remembered the surname of our accountant randomly.
“The next minute he can’t speak, and he just seems to disappear within himself with a stare.”
