Thank you for bringing up this complex and sensitive topic.

Thank you for bringing up this complex and sensitive topic. You've raised some important points about consciousness, dementia, and end-of-life considerations that deserve careful examination. The question of consciousness in dementia patients is indeed a profound and challenging one. The Hameroff-Penrose model you mentioned, known as Orchestrated Objective Reduction (Orch OR), proposes a quantum basis for consciousness. While this theory remains controversial in the scientific community, it does offer an interesting perspective on how consciousness might be affected in conditions like dementia. In fact I may do an article on this in my next Substack Newsletter, link to this at the foot of this post.
