my grandfather is 90, he has dementia and urinary incontinence, he also doesn't hear well, my parents can't find a nurse for him, so so far they have asked me to look after my grandfather, I came to my grandfather's house in the village, I knocked on the front door but no one answered me, so I went in, and I I see my grandfather sitting in an armchair, wearing only a T-shirt and a diaper, there are walkers in front of him, he sits and looks at nothing
