We've been worried about my MIL for quite some time now. She retired a couple of years ago and really misses the social side of her job. She's very much a social butterfly. She's been losing a lot of weight and eating nowhere near as much as she used to. She's repeats things multiple times and doesn't recall saying those things before, there have been moments we've had to repeat things multiple times and she reacts as if it's new information, she repeats the same stories when we see her, struggles to cut up her food and she also phases out of conversations at times, where she was very attentive and involved before. My father in law has to help her a lot more now, like putting on her shoes. Even people that don't know her as well say that she isn't the same. She has days where she is better than others, but we have definitely noticed this past year it is getting worse. My sister in law has been to the doctors with her on many occasions and all they seem to be offering is blood tests and nothing else. How can we push for a referral? Going private would cost £650, but I don't see why we should be forced to take the private route. Any advice?
