This is unfortunate in many respects as her quality of life is poor regardless of what appears on the surface. But our hands are tied when the person involved digs in their heels and is doing their utmost to hang on. Dementia, in particular, is an issue where there may be more resistance than average because the person is struggling to make a connection to the outer world, and this keeps their focus on wanting to be in the earth plane very, very, strongly, as opposed to making a judicious exit. Unfortunately, that is the mindset she is in currently. She is wanting to reclaim what she is aware has been lost, and as long as that is a strong desire it will reduce the effectiveness of any encouragement to transition. So time will tell how things go, but you have done the best you can here. There are potential benefits from doing further sessions but, as you know, this can be quite a long-term proposition when an entire lifetime has gone into bringing about her cognitive decline. So there would be much work involved with an uncertain prognosis given the advanced stage of her decline.
