A distant relative has apparently become increasingly delusional over the past few weeks. At this point, he's constantly seeing people 'invading' his house....very large people with big, flat heads about the size of a large pizza... He's also getting increasingly confused and upset about not being able to remember things. His kids have taken away his guns and knives (at least I hope they got all of them) out of concern that he would either hurt himself or someone else. At this point, he's afraid to stay in his house because of the 'invaders' and one of his sons has moved him in with his family for the time being. His kids have made an appointment for him at the VA hospital in northern Utah, but it's not right away. His DIL is convinced that it's mold in his house that is making him ill, but while it's a possibility I'd be more concerned about a possible physical cause (brain tumor, metabolic disorder, etc.) I suppose if he improves at his son's house that it's probably indicative of an environmental cause.
Anyway....any of you in the medical or mental health fields have any advice for his family while they wait for his appointment?
Modified to add - he was at our house on the 4th of July and seemed fine at that time. None of us noticed any discernable changes in mental state at that time, although of course we have no idea how long he's been having these issues. Things just seem to have really escalated in the past 4-6 weeks....
