In stressful situations like emergencies and hospitalization, people with Alzheimer's or other dementias may feel frightened, confused, and agitated. This can lead to uncooperative or aggressive behavior. In the hospital, they may forget how to work a call button or try to get out of bed with a broken hip. For these reasons and others, someone should remain in the hospital with them as much as possible to see that they get the best possible care and to explain the dementia to each staffer encountered. It’s also important to plan carefully for discharge.
