I have been caring for my elderly mother with Dementia for the past 5 years. She lives in private sheltered accommodation. A Carer or myself visit 3 x daily to see that she is okay and I take her out for lots of outings and drives. The lady who lives opposite my Mother also suffers from Dementia but sadly does not seem to get much support from her family. The lady opposite has been continually ringing my Mother's doorbell and going into her apartment throughout the day and helping herself to my Mother's food and asking to borrow money etc. We tried putting a "Please do not disturb as resting" sign but this is just ignored so my Mother has her important rests disturbed. My mother is also frail and registered blind.The other lady has also been going into my Mother's apartment after we have put my Mother to bed. We have been so patient and this problem has been going on for about 2 years. When I asked the Manager about this problem she said she would speak to the lady's family but nothing ever changed. She also said my Mum is fine about it all! Sometimes I find the lady drunk in my Mother's apartment and she slept on my Mother's sofa one night. Unfortunately my Mother is very frail and she is also very kind and her good nature is being taken advantage of. We estimate that this lady is costing my Mother around £75 per week in food and "borrowed" money. I feel very sorry for the other lady as she has very little contact or visits from her family. She definitely meeds support and help. I am wondering in the absence of any support from the Manager what are my Mother's rights?
