Yes, please edit TV viewing where you can. My Granny’s favourite Tv show was Midsomer Murders, which she insisted on watching on rotation. Even when she was still in her own home and compos mentis, she’d get visibly annoyed if we visited while it was on. She ended up believing her entire family had been murdered. Eventually we couldn’t even phone her, as she was convinced we were scammers, impersonating her dead relatives to trick her.
