My 81 year old stepdad just had what appeared as a stroke to those who were with him but test seemed to show the old stroke and not a current one, he had hit his head 3 wks prior and seemed more tired than normal, should the test him for a longer period re the mri , cat scan. He is at Hershey medical center and I live out of state, I am concern he didnt get need tap if there eas a stroke. He is week on right side and speaking some gibberish.
