I was advised that my mother has dementia. My siblings and I have not been very close for years. I live across the country. I have emailed & phoned, but get little response. Any information is vague. Both my siblings share Durable Power of Attorney. I have always kept in close touch with my mother and noticed her forgetfulness. Then my sister moved mother to her house and took her phone away from her without telling me. It was months of emails and calls to them both before I was told what had been done. Mother has been there over a year and they're still keeping up the pretense she is living in her condo, which has a reverse mortgage. This is suspicious to me. I have no idea what their plans are, but do feel she's not getting the optimum care she needs. This is very difficult for me.
