Short answer. Agitation and aggression sit on a spectrum but are not the same. Agitation is restless, distressed behaviour — pacing, calling out, resistance, escalating tension. Aggression is the physical end of it: hitting, grabbing, pushing, or combativeness, most often triggered during hands-on care such as bathing, dressing, or toileting. The research-backed approach to both is the same and it is nonpharmacologic first: treat the behaviour as a communication of unmet need or a reaction to what is being done to the person, and use the DICE approach (Describe, Investigate, Create, Evaluate) to find and remove the trigger (Kales, Gitlin, & Lyketsos, 2015; Gitlin, Kales, & Lyketsos, 2012). For physical aggression specifically, the first priority is safety — create space and stop the triggering activity — and only then decode.
The behavioural-symptoms literature treats agitation and aggression as neuropsychiatric symptoms of dementia, not as willful acts. Gitlin, Kales, and Lyketsos (2012) and the follow-on DICE framework (Kales, Gitlin, & Lyketsos, 2015) reframe them as the visible end of an unmet-need pathway: pain, fear, overstimulation, a misread interaction, or — very commonly for physical aggression — the experience of being touched or moved in a way the person does not understand and cannot consent to.
This distinction between agitation and aggression matters for the caregiver in two ways. First, physical aggression is disproportionately care-related: the most combative moments cluster around intimate care tasks, where a person with dementia may perceive help as an intrusion or an assault. Second, the safety stakes are higher, so the response has an extra first step — protect both people — before the decoding work begins.
The evidence is consistent that nonpharmacologic strategies should be tried first for both. Antipsychotics carry well-documented harms in dementia and offer modest benefit; major guidance places behavioural decoding ahead of medication for most agitation and aggression, reserving drugs for severe, persistent cases that do not respond and are handled in clinical partnership (Gitlin, Kales, & Lyketsos, 2012; Alzheimer's Association, 2024).
| Agitation | Aggression | |
|---|---|---|
| What it looks like | Restlessness, pacing, calling out, repetitive requests, rising tension, verbal resistance | Hitting, grabbing, pushing, scratching, biting; combativeness |
| Most common trigger | Overstimulation, unmet physical need, disrupted routine, sundowning | Hands-on care (bathing, dressing, toileting); feeling cornered or intruded upon |
| Primary risk | Distress, escalation | Physical harm to the person or caregiver |
| First move | Decode the unmet need; lower arousal | Ensure safety and stop the triggering task first, then decode |
| Medication role | Nonpharmacologic first; drugs are last resort | Same — nonpharmacologic first; drugs reserved for severe, unresponsive cases |
Agitation often precedes aggression, which means the most reliable way to reduce physical aggression is to catch and defuse the agitation earlier — before it reaches the physical end of the spectrum.
When aggression is physical, order matters. Safety comes before decoding.
Once everyone is safe, run the DICE pass (Kales, Gitlin, & Lyketsos, 2015):
Sustained or worsening aggression, or any pattern that puts someone at risk, warrants a clinical review — and the first questions there should be about pain, infection, medication, and constipation, which frequently drive escalations that look purely behavioural. Medication is an adjunct for severe, persistent cases that don't respond to decoding, not a first line (Gitlin, Kales, & Lyketsos, 2012).
This page is about the distinction between agitation and aggression and how to handle the physical end safely. For a deeper framework on why agitation episodes happen and how to find the unmet need behind them, see the companion page on decoding agitation episodes.
The pattern under most of these is care-triggered: the aggression clusters around bathing, dressing, and toileting. Recognising it as a reaction to the task — not a change of character — is what makes the DICE modifications work.
