we have found that you have to be prepared to shout about your problems to Social Services as well
Total agree with that . also if your mother forgetting to give herself her insulin if can make her mental health worse that what my doctor told me when mum was not taking her medication for diabetes .
so may be that also why you may be seeing a worse decline even with medication she taking for her dementia
You could also as the doctor to do a referral to the district nurse to make sure that your mother taking her insulin injection , they give your mother high priority in visiting her because she insulin dependent . but the main issue is and only you know would your mother cooperate with them , meaning letting them into the house to help her .
As from mt experience from my mother she would not let them help her , as she was so confused .
I also had all the issue you having with your mother in not wanting to wash herself nor change her clothes , all I can say is don't take it personal , she vent out her anger on you because she must know that if she does it to someone in authority they could section her , she not stupid .
when she got so angry with me it felt to me like a teenager getting angry at me, because they don't understand they emotion so they let it all out on me because I am they mother if you get my point
you now in a stage that you have to except that your mother is still your mother , but its not the same relationship as you had in the past, so your grieve for that past relationship and it take a lot of self help on your part to except that , other wise your future is going to get very frustrated as I know I did .
I never wanted this mother I was now seeing , but over the years I came to release that it was the disease doing this to her , because I remember how she was before .
back then I would think she trying to wind me up doing it on purpose , because all of a sudden her real personality was back , the next min it was gone . I had know my mother all my life since childhood how can a disease change her so much it was really not nice to see .
it was hard mentally for me to take it all in what was happening to her .
I do wish you all the best in getting all the support from CPN , SS , Doctor .
