Dad has COPD + Parkinson's & unable to move upper arms. Mother has heart condition + Alzheimer's and falls frequently. They live in an independent facility at this time with no nursing care. There are 5 siblings who cooperate & share the common concern for our parents' quality of life. Mother's confusion has escalated, almost as if hallucinating. Dad is not able to help her up when she falls. We fear for their safety. Where do we go from here?
You may find that the director has them on her/his radar. They may already be getting some help informally (like the staff responding when your mom has fallen). When that starts to occur, they'll start tracking their needs and at some point you'll get a request for a sit-down.
I agree with the previous poster that their doctor should be consulted. However, keep in mind that s/he only sees them briefly during visits (and elders are often putting on their best face for the doctor). The dementia spectrum is so broad and nuanced that you really need to live with someone to see how they are. A doctor may test for their 'level', but that doesn't begin to give a real picture of how a person lives.
Assisted Living is great when it's needed, but if they were my parents, I'd want them in the least restrictive environment possible. If they like where they live, why not stay if they can?
Hope all goes well.
