New here. Main caregiver for my dad who still lives alone. He's paranoid schizophrenic, on meds, but his mental state has declined since having a heart attack and stint placement in April. He's delusional. People are coming in at night stealing his groceries & clothing but they leave some of those things also. They've left food he doesn't like. Food that he's normally eaten as long as I've been alive. His mental health provider says dementia/sundowners or possible stroke. He has a primary care appt later this week. I've talked to the dr to let him know what's going on. I told him I need to know what to do. He said we'd talk about what to look for, what to expect, etc.
I'm also probably going to get a nanny cam before his appt. I'm curious to see if he's up at night.
I would also be concerned about his delusions. We had a family friend with dementia who had delusions. He lived alone and he became convinced that there were loud children inside his home. He ran out into the street, fell and fractured his hip. He never recovered from it. So, delusions can cause the patient to harm themselves or others. I'd stress that to his healthcare providers.
If it turns out to be Alzheimer's/Dementia, here on this Aging Care website are excellent articles. Scroll down to the bottom of the age to the blue section, and click on ALZHEIMER'S CARE.... now start reading.
Hopefully the doctor will be able to narrow down the issues, and possible give Dad some meds to help him out.
