Seek emergency help when physical aggression—actions that could physically harm someone—creates an immediate danger to the person or others. Seek prompt medical help for aggression that begins suddenly, is new, or is getting worse. Aggression does not always mean dementia has progressed. Pain, constipation, infection, medication effects, sleep loss, hunger, thirst, or problems with care or surroundings may contribute.

When is aggression an emergency?
Treat the situation as an emergency when you cannot keep the person, yourself, or others safe. Do not remain within striking distance while trying to reason with the person.
The National Institute on Aging advises caregivers to: These steps prioritize immediate safety while giving responders important context about the person's condition. The National Institute on Aging's guidance also identifies worsening aggression as a reason to contact a doctor.
- Protect themselves and anyone nearby.
- Stay at a safe distance.
- Call 911 when the aggression creates an emergency.
- Tell responders that the person has dementia.
Why does sudden aggression need prompt assessment?
A sudden behavioral change may point to a treatable physical problem rather than dementia alone. The NHS says abrupt aggression warrants prompt clinical assessment because possible causes include pain, constipation, infection, and medication effects. The NHS dementia behavior guidance emphasizes looking for these underlying causes.
Contact the person's doctor even if the immediate episode has passed. Describe when the aggression began, whether it was out of character, and what happened just before it. Before the appointment or call, make a short record of:.
- Signs of pain or physical discomfort.
- Constipation or possible infection.
- Recent medication additions, removals, or dose changes.
- Sleep loss, hunger, or thirst.
- Changes in routines, surroundings, or how personal care was provided.
When should recurring or worsening behavior reach a doctor?
Contact the person's doctor when aggression becomes more frequent, more intense, or harder to manage safely. A medical review is also appropriate for any new behavior, even when it developed gradually or caused no injury. Do not assume repeated aggression is an unavoidable part of dementia.
A thorough checkup can look for pain, infection, medication side effects, and unmet physical needs that the person may have difficulty communicating. Explain the behavior in concrete terms. Report what the person did, how long it lasted, who was present, and whether a particular activity or care task came before it. Also mention whether the behavior settles when a physical need or environmental problem is addressed.
What should professional care address first?
Clinical care should begin by examining possible medical and environmental causes. This includes pain, delirium—an abrupt disturbance in attention and awareness—and care practices that may be distressing or inappropriate. When immediate danger is absent, non-drug measures usually come first.
These measures focus on treating physical causes, adjusting the surroundings, and changing how care is delivered. NICE's dementia recommendations direct clinicians to assess these factors and use psychosocial and environmental approaches as initial management. The response should match the cause. For example, aggression linked to pain calls for clinical attention to the pain, while distress during a care task may require changes to the approach or setting.
When might medication be considered?
Medication is not the default response to physical aggression. A doctor may consider it in selected cases, but only after assessing clinical and environmental causes. NICE limits antipsychotic treatment to people who risk harming themselves or others or who are experiencing severe distress.
When prescribed, clinicians should use the lowest effective dose for the shortest time and reassess treatment at least every six weeks. Families and caregivers should ask what specific symptom the medicine targets, how benefit will be judged, and when it will be reviewed. NICE's antipsychotic medicine decision aid reports increased risks of stroke and death, so clinicians should discuss expected benefits and harms with the person and family or caregivers.
