My grandfather had a similar fate. Roughly 4 months before his death, my uncle was taking care of him for a week while my grandmother was traveling. My uncle had, for the longest time, been adamant that the medication had made his dementia worse. Unbeknownst to the rest of the family, he stopped administering the dementia meds for the week that he was caring for him. It was bizarre interacting with him during this lucidity. He was able to do most physical things without assistance (he still had a bad hip) and you could engage with him in conversation. He knew who I was without prompting, something he hadn’t been able to do for about 4 years. He knew all his children and grandchildren. He also shared stories from his middle years, something he had stopped doing during the early stages. It wore off though, in about a week or so he began to have the brain fog set in. His doctor was also not too happy to hear about the withdrawal. The only person who seemed disturbed and worried about this moment of lucidity was his caretaker, who had worked with dozens of elderly folks with memory issues prior. She said it almost always happened before a sudden decline. She was right, about 3 weeks later he became very ill and then died within a few months.
