My MIL was diagnosed with stageIV lung cancer with mets to the brain in May 2006. Since June she has had full brain radiation, 2 rounds of chemo, a brain tumor removed, and most recently, gamma knife radiation on two more small brain tumors. On Saturday she was alert and seemed herself and at our house for a visit. Monday morning I found her unresponsive laying in bed. We brought her to the ER and the only thing they could tell us was that she was very dehydrated. She has been on fluids since Monday afternoon, but she is still completely confused to the point of not even knowing where she is. She is talking about things that happened in the past. While in the ER they did a ct scan and an MRI but didn't see any more brain tumors. No one is able to tell us why she is so confused. This happened so fast and I don't understand why. I am waiting on a call back from her oncologist to see if she can tell us what to expect next. If she is currently in the hospital, can she be evaluated by a hospice nurse? She has not eaten since Sunday night and I am very concerned that we are going to lose her soon.
