We are all very worried about my grandmother who is 92 and fell and fractured her femur last week. Prior to this she was of sound mind, lived in her own flat and cooked and went shopping for herself. After surgery a few days after she has rapidly changed into a different lady she is hallucinating , not making sense, ringing relatives up and asking where they are and just general confusion. It's so upsetting and we are at a bit of a loss. She has had all the standard checks done eg bloods, urine and they have come back clear so leaning towards the trauma of the injury and delirium taking hold ? Has anyone got any advice as doctors don't seem too worried and just think she's a frail old lady with dementia when she was not before entering the hospital ..... many thanks for reading
