Mom started acting and speaking irrationally during a stint in an ICU. Drs said it was ICU psychosis due to isolation. My sister, also an RN, thought it may have been a stroke. After getting her out of that hospital and away from those Drs, we found out my sister was right. Mom was subsequently diagnosed with onset Alzheimer's.
