Sudden change is usually medical, not decline
A sudden shift in confusion, alertness, behavior, or a new fall over a day or two is rarely the dementia itself getting worse. It is most often something acute and treatable. An infection, dehydration, a new medication, constipation, untreated pain, or a small stroke. Doctors call this delirium and treat it as an emergency, because the cause can be serious. The next hour is for finding and fixing the cause, not accepting it as the new normal.
A facility has a duty to assess, call a clinician, and tell you. You are usually not in the room, so your leverage is to name that duty and get it on the record.
