My 93 year old mum has a diagnosis of mixed alzheimers & vascular dementia and lives at home. I am her carer and struggling to give her the level of support she needs and support my brother. My brother has cancer and has just been advised he has a limited time left. I feel she needs to know if only so she can say goodbye, but know that she won’t remember and will be going through the trauma of finding out repeatedly. My brother would also like to say goodbye to her. Any suggestions please?
