My 75 yr old mother-in-law has begun wetting her bed, leaving the house and lying about her whereabouts, saying she is dying and not eating, continues to make up stories and in general be angry and disconnected to family. Recently, she went to the hospital and the doctor said she appears to be in advanced stages of dementia. When reading online about legally obtaining guardianship it says she must be deemed incompetent. Is this something the court will do in the process of the hearing or is this something the family must do, i.e. have a Licensed Social worker and/or doctor make a diagnosis?
