My dad is 93 and has dementia. My husband is his full time caretaker. We have grown accustomed to the tissue hoarding aspect of this disease, but is anyone else experiencing their loved one drinking from a water bottle for a sip or two and then pouring the bottle out either on the ground or in his lap. At dinner he has taken his glass of water poured it into the floor. Always denies doing it. Is this his own quirk, or have you also experienced it?
