question: My 87 year old father fell off a ladder approx. 1 1/2 year ago.  He broke both arms and shattered his left wrist which now has a plate in it.  He also hit his head.  He was taken to the hospital and they did tests to make sure his head injuries were not life threatening.  He is now 88 and is going to a geriatric psychiarist and takes anixiety medecine.  They do not seem to be helping him.  He is lathargic and  sleeps most of the time.  He has no apetite.  I was reading about dementhia and I would like your professinal opinion on should we request this test be done.  His caregiver is my Mom who is 87.  My sister and I live about 4 miles from them and are there when needed but also give them the respect they deserve and not smother them.  It just seems that all they want to do is give him pills and have not taken any test such as for dementhia, alzheimers or parkinsons.  We dont know where to turn.  The Dr.s he goes to are not very understanding.  Please respond.
