In July the family went on holiday leaving mum in the care of the nhs. Sadly she received a morphine overdose that stopped her breathing and sent her into a coma. She now has dementia and its been so hard to see her normal one day and a person we no longer know the next day. I can't begin to tell about the terrible abuse she has given us, calling her granddaughter a prostitute for one thing? I'm devastated. Has anyone else experienced such a dramatic overnight change and how did you cope? Is it normal dementia behaviour to be so preoccupied with death and debauchary?
