My wife is currently caring an elderly man suffering from Dementia. His short term memory is very poor and he is constantly asking for his wife. his wife died recently and he becomes very upset when told this, he soon forgets the fact that she has died and when told again becomes very upset. My wife has been told by her supervisor that she must not hide this information from him and he must be told if he asks. She finds this very upsetting and questions the benefits of this practice. Any views on this matter would be helpful or any web sites giving advice on this matter would be appriciated. Thank you.
