Dad, 95 with Dementia is in AL Memory Care. 3 months now and he's been a pleasure they tell me. Until recently. He also has 70 to 90% blockage of the right carotid artery. Anyway, he walks around the facility constantly. No problems until recently. He screams at other patients who also walk. Lately he's put his fist up to another man's face. To me that is totally unacceptable. First time I saw him raise his voice, I told him that was being rude and we are not rude people! Now the AL is testing him for a UTI. They tell me that it's very common and will lead to aggression. I'm not sure if it's that or progression of Dementia. I am not against a mild tranquilizer if needed. Of course I'm hoping it's a UTI. His unit is small, only about 20 people and only he and 3 others walk unassisted. Anyone else encountered this with their loved one? Am I wrong to suggest medication?
