text: does anyone know what "sun-downing syndrome" is?   usually that refers to a condition where a person becomes confused at night.  such as when a person suffers from a form of dementia, they can often keep it together for only so long during the day.  at night, when there is less stimulation to keep them alert, or they become fatigued, they just can't control their symptoms as well.  this is when they may become agitated or combative.
