My MIL has been in a care home for six weeks - emergency social worker involved over Christmas as she physically assaulted ( not for the first time ) her husband age 87 . She does not appear to be settling and we have been advised she may need to move to an EMI unit due to her challenging behaviour . She has hit back at staff and other residents but we don't seem to get much detail from the home . Today I visited with my daughter ( her grand daughter ) who she remembered and seemed content with our company for about an hour . We said goodbye and she said she was just having a rest before lunch - she seemed fine . We tried to leave but the lift was broken and we had to walk back into the dementia unit to leave via the staircase . We heard her before we saw her !! She was hysterical crying out - where am I ? Where is Ron ? Take me home !! Etc etc . I calmed her down and spoke to the staff . Apparently this is how she is whenever she is not with family visitors and it is this behaviour that leads to other residents telling her to be quiet and her arguing and then hitting out . What can we do as family to help as we can't be at the home 24/7 ? How will an EMI unit work any better ? Any advise appreciated
