When physical aggression—behavior that could physically harm someone—starts, stop the care task, stay calm, and create distance if you can do so safely. Do not argue, restrain the person, or insist on finishing bathing, dressing, medication, or another task. Aggression can occur alongside agitation in dementia, but it may reflect frustration or an unmet need rather than deliberate intent. Once everyone is safe, look for triggers and arrange medical assessment if the behavior is sudden or worsening.

What should you do during an aggressive episode?
Lower your voice and use short, reassuring statements. Acknowledge the person's feelings instead of correcting facts or trying to prove a point, as recommended by the Alzheimer's Association. For example, say, "You seem frightened.
I'm going to give you some space." Avoid questions or explanations that demand sustained attention. When it is safe: Completing the task is less important than immediate safety. Pressing ahead may intensify an interaction the person already experiences as confusing or threatening.
- Step back or leave briefly.
- Reduce noise and move other people away.
- Redirect attention to a calming or familiar activity.
- Postpone the care task until the person is calmer.
When does aggression require medical attention?
Arrange a medical assessment when aggression begins suddenly or becomes more frequent or severe. The National Institute on Aging identifies possible triggers including pain, infection, depression, constipation, poor sleep, medication effects, and medication interactions. Record what changed and when.
Note recent sleep, bowel habits, signs of discomfort, medication changes, and whether episodes cluster around meals, personal care, or particular times. Do not assume a new behavior is simply an unavoidable stage of dementia. A clinical assessment can help identify a treatable source of distress.
How can you identify and reduce triggers?
Write down what happened immediately before, during, and after each episode. This simple record can reveal patterns that are hard to notice during a stressful event.
Look for environmental and communication triggers such as: Change one likely trigger at a time. For example, offer one-step directions, allow more time, reduce background noise, or try personal care with fewer people present.
- Loud noise, clutter, or crowds.
- Unfamiliar people or surroundings.
- Rushed demands.
- Instructions with too many steps.
- A task that appears to cause fear or frustration.
What should a household safety plan include?
Secure firearms, kitchen knives, car keys, and other items that could cause harm. Decide in advance where other household members can go and whom the caregiver can contact for immediate help. If aggression continues, maintain a safe distance and seek help.
Do not move closer merely to calm the person or recover an object when doing so could put someone at risk. Call 911 when the situation is an emergency. Tell the dispatcher and responders that the person has dementia and is acting aggressively, guidance also given by the Alzheimer's Association.
When might medication be considered?
Clinical guidance recommends trying psychosocial and environmental measures first. These approaches address the person's distress, surroundings, communication, routine, and possible unmet needs. The NICE dementia guideline reserves antipsychotics for situations involving risk of harm or severe distress.
It recommends the lowest effective dose for the shortest feasible period, with review at least every six weeks. In the United States, FDA-approved options for agitation associated with dementia due to Alzheimer's disease include brexpiprazole and, since April 30, 2026, Auvelity. These approvals do not cover every dementia type, and both medications carry important safety considerations that require an individualized discussion with the prescribing clinician.
