Hi!
Unfortunately, it's been my experience that one has to wait until the disease progresses to the point where the parent becomes a danger to self or others. It is like living a Nightmare!!!!!
But when he/she reaches that stage it's best to just call the cops, because he/she can have incredible stregth and can literly be dangerous to be around.
Then as usually happends the parent is held either a week or 48 hours for an evaluation, and then released, it's up to the patient to take his/her meds, and usually they don't like to take them, which means the whole cycle will repeat in just a matter of time.......

You could speak with legal aid or an attorney to see, what one can do, but I think it's usually up to the patient to ask for help..........

It's all rediculous I know...........

What are her current symptoms?
