I am noticing that Dad is nearly always looking asleep. I try to spend time sitting in same room but he always looks asleep but will occasionally lift head and open eyes. TV is on with programs he expresses an interest in but doesn't appear to want to watch. Maybe this is cataracts and he couldn't see clearly even if he was looking. Maybe it's dementia taking hold. What have others noticed caring for someone with Vascular Dementia? is this sleepy phase quite late in the advanced stages? I came downstairs to take dog in garden at 3.00 AM and he was wide awake watching tv quietly. He's not going to bed or putting his feet up at the moment but sitting in chair 24/7. Nurses have also told hiom to lie down but he won't.
