How can we help Mom stay safe in her home?

Delana635 asked...

My 72 year old mother has many signs of dementia. She tried boiling eggs on the stove in a glass mixing bowl,(it shattered) she'd sooner wet the bed & lay in it than to walk across the hall to the bathroom, she believes her dog talks to her, she repeats herself constantly, she can not follow a conversation among many other things, however, the hospital says, "She presents well." She is not safe at home but we can't get anyone to help us. What can we do to make sure she is safe?
