Families should seek prompt medical care when agitation—a marked increase in restlessness, distress, or aggression—begins suddenly or is clearly worse than usual. Call 911 or the local emergency number if anyone is in immediate danger or the person suddenly cannot speak or move one side of the body. Not every episode requires an emergency department visit. Agitation can occur in advanced dementia, but a new pattern may signal pain, illness, dehydration, infection, or a medication problem rather than dementia alone.

When is agitation an emergency?
Call emergency services when aggression creates an immediate threat to the person, a caregiver, or anyone nearby. While waiting for help, avoid touching or restraining the person unless doing so is necessary for safety, as MedlinePlus advises.
Sudden trouble speaking or moving one side of the body also requires urgent medical attention. These can be stroke-like symptoms, according to NHS dementia guidance. Do not wait for the agitation to settle before seeking emergency help when either danger or stroke-like symptoms are present.
Which changes require a prompt clinician call?
Contact the person's dementia clinician promptly when agitation accompanies a clear departure from their usual behavior. Warning signs include: Sudden yelling, striking out, grimacing, disrupted sleep, frequent repositioning, refusal to eat, or labored breathing may also signal pain or illness.
This matters when the person cannot explain what hurts or feels wrong. Fever, infection, dehydration, and medication effects can cause an abrupt confused state called delirium. The National Institute on Aging recommends medical assessment when behavior changes suddenly or becomes markedly worse.
- Sudden confusion
- A major change in memory or mood
- Fever
- Fainting or falling
- Sudden incontinence
What treatable causes should be checked?
New agitation should prompt a search for physical discomfort and other treatable contributors. The behavior may be the person's only visible way of communicating a problem.
A clinician may need to consider: The Alzheimer's Association's treatment guidance emphasizes evaluating these contributors before deciding how to treat a new behavioral symptom. Families can help by noting when the change began and what physical signs appeared with it.
- Medication side effects or interactions
- Infection-related pain
- Constipation or urinary retention
- Hunger, thirst, fatigue, or a full bladder
- Skin irritation or uncomfortable temperatures
What can families do while arranging care?
If no one is in immediate danger, reduce noise, activity, and other stimulation. Check whether the person is hungry, thirsty, tired, too hot or cold, constipated, uncomfortable from a full bladder, or bothered by skin irritation. Compare the episode with the person's usual pattern.
Record what happened beforehand, how long it lasted, and whether eating, drinking, sleep, movement, or toileting changed. These details can help the clinician distinguish an ongoing dementia symptom from a new medical problem. If the behavior escalates into immediate danger, stop trying to manage it alone and call emergency services.
Is medication always the answer?
Medication is not a universal treatment for agitation. A clinician must weigh the type of dementia, possible physical causes, symptom severity, and medication risks. The FDA approved brexpiprazole specifically for agitation associated with dementia due to Alzheimer's disease.
That approval does not cover every cause of agitation or every form of dementia. The FDA approval notice also notes that antipsychotics retain a boxed warning about increased death risk in older people with dementia-related psychosis. Before discussing medication, bring the clinician a brief record of the behavior, its timing, accompanying symptoms, and any recent medication changes.
