Dear Bill- the degree of confusion your father has seems rather severe-- but some confusion in a strange and stressful setting like hospital or nursing home is not unusual. There's even a so-called "sundown syndrome" which describes the disorientation, often at night, that older patients experience. Even a brief stay can cause some confusion, as we learned when Peter was an inpatient for one day,not even over night, to relieve an impaction and he found all his PD symptoms worsened, a little confused, very shaky,etc. Onthe way home he commented that when we left home this AM he didn't know he was "going to Chicago"! (I assured him he didn't!) This has mostly ended now, but may be at least part of your father's problem.I hope when he's back in familiar surroundings it was gradually pass. How worrisome for you all now, though. Take care. Camilla Flintermann,CG for Peter 78/7,Ohio
