Mother age 66 she is affected delusional syndrome. she refused to take treatment &bills.she thinks we are giving poison&acid. can it be without bill?

What's your question: Can WHAT be without a bill? This forum is free of charges to the public. All you need to do is pose a question. If your mother is refusing to take any treatment and she is thinking you're trying to poison her then, several possibilities come to mind. She needs labs & an imaging study of the head. Call the doctor for advice on how to get this done plus get treatment into her if she is refusing.
