Can a patient be asked to leave a memory care facility due to aggression, anger, and other bad behavior with no notice?

Oh my what a stressful situation....for everyone. I know when I have visited facilities, there were places that my parents could not wait to leave because of a certain overbearing resident. If it is not a palatable environment, pretty soon customers will shop elsewhere, and residents will want to move out (if the problem isn't resolved) and the facility management is keen to resolve problems quickly. Yes I did refer to the outbursting patient as a problem, because in a facility everyone becomes qualitified, according to their needs, they have to make decisions on levels of care, and facilities want to balance the level of care "mix" with their staffing requirements. So if there is one person who's off the charts with their needs, they are going to have a very hard time meeting everyone's needs, safely. Thus the imperative to have those patients evaluated for different or more medications. Are there any treatments such as brain stimulators or implants, to help curb the outbursts? Would seem to be a worthwhile endeavour.
