Hi, my husband has Parkinson’s Dementia diagnosed 6 months ago and recently has started to have hallucinations. I tell the people he sees at night to leave the house and not to come back and this usually works. However he now asks how they got into the house and I don’t know how to answer that question. He says we should call the police beause the house isn’t secure if these people can get in. Please could you advise. Thank you.
