My husband and I believe that his mother has the on set of dementia. She doesn’t remember where any one in the family lives. And she doesn’t really drive because she says she doesn’t remember how to get there. She is really nasty and thinks my husband is out to steal her money.  She’s like a stranger to our kids and on occasion has made my oldest daughter, who she always claimed was her favorite cry.  How do we get this person to see and doctor?
