My JW father ( in his late 70's ) suffered from delirium, and was hospitalised for 5 months in 2018.
This is what I recall of our family experience here in Australia:
In early December 2017, Dad was told he would be having an operation in mid-late January 2018 to replace a leaky heart valve.
( unbeknownst to people who were there )
gone into a state of delirium at my parents home in Victoria, I was able to hear what was transpiring via phone link to me in New South Wales with JW family who were in attendance... he was making all kinds of accusations ( I won't go into detail here ) about some people, including my siblings and Elders at the hall..... a local congregation Elder had come to Dads house and was in the process of getting into a heated argument with my father....
