Hi AnitaJo Page In response to your query re Sundowning, I have heard the term but not in reference to PD.I do recall its use in the depression days of the late twenties / earlier thirties in Australia and New Zealand to describe homeless men who lived on the road in rural districts and they would arrive at a farm homestead at sundown (when work has stopped) with the hope of receiving a meal and a bed for the night (usually in an outbuilding). It was customary for them to offer to chop fire wood (after breakfast !!) in the morning but not for long as they usually liked to be on the road early before the sun became too hot !! They were known as "Sundowners" particularly in Australia but in New Zealand they were also known as "swaggers) Hope this is of interest Best wishes Jim Caldwell PwP 76/10
