My Mom is 90 years old and two weeks ago experienced difficulty standing and wheezing when breathing. She was hospitalized and treated for a small amount of fluid in her lungs. She improved though was having difficutly swallowing and still unable to stand with help. The hospital transferred her to a rehab facility 4 days ago and now she will not talk, move her arms or legs, will not sit in a wheelchair, tries to slide out of the wheel chair when a hoist is used to transfer her from the bed. She also doesn't seem to recognize me and will not keep her eyes open. I have no idea what is going on. She had a small brain bleed 8 years ago, which affected her short term memory but has been able to walk with a walker from the living room to the bathroom. All the hospital tests were normal (heart, lung, brain (showed small residual from stroke), no new TIA. Any thoughts? It's like something is attacking her brain, but brain scan showed nothing.
