He doesn't sleep during the day or at night. He goes thru all cabinets. I'm scared he'll eat something not edible. Tonite he's up at 1 AM going thru fridge drinking god knows what. Before I caught him with a bottle of ketchup going into his mouth. And he smelled like pancake syrup so I can only imagine what he had already stuffed himself with. He says he's starving and that nobody is there to feed him. I have noticed his mind and body have declined quite a bit over 2 to 3 months. Please help, I don't know what to do with him anymore. My mom as well is 90yrs old, he is very demanding of her so I try and keep her out of his sight. My poor mom is getting close to dementia herself but I would appreciate someone helping me to solve his sleep and behavior.
