My sister was diagnosed with frontal temporal dementia in October 2017 by a doctor in Texas where her only child lives. She just recently had a PET scan in Phoenix (where family lives) and the neurologist confirmed that she has FTD. Her bazaar behavior patterns have increased tremendously in the past months.
Be proactive. Research, research. research. Go visit facilities that might be good for her. In this situation, if she is willing, it may be best to move her to a facility near family.
Hope this helps you!
People who have dementia cannot safely live alone beyond the very earliest stage. It sounds like your sister is past that, and is declining.
Among the first things your sister will need help with is where she will live. Can she get by with some in-home help for a while? Or does she need 24-hour supervision? Can she afford that in her home? Is moving in with a family member a suitable option? Assisted living? Memory care? A nursing home? There are lots of related issues, but I think the first decision has to be where will she get the supervision she needs to keep her safe.
Family meetings are a good idea, especially if family is genuinely interested in Sister's welfare. But it is also important that there is one person in charge. Getting financial and healthcare POA in place is very important. Family input is great. Decisions by committee don't often work well.
Keep in touch here. It helps to not be alone.
Next thing is can she private pay for a facility until she qualifies for Medicaid.
If possible your family meeting should be one on one. The person willing to have her near them, should check out what services thst are available in their area. Office of Aging and Social Services are good places. I would also call the local Medicaid office to find out when she would qualify. Someone needs POAs if she is able to understand what they are. Otherwise, its guardianship.
We have looked into legal guardian ~ but the attorney we talked with in Utah doesn't feel we have strong enough evidence.... he said "making bad decisions doesn't mean you can strip a persons rights." I do understand what he is saying, but I am afraid that something is going to go very wrong soon. However, the conversation was a couple months ago and bazaar behavior continues to increase.
