Agitation in dementia shows up as restlessness, pacing, shouting, or physical aggression, and it almost always has a specific cause behind it. Pain, poor sleep, constipation, a soiled diaper, medication interactions, or a loud, overstimulating room are common triggers, and finding the trigger often stops the behavior without medication, according to the National Institute on Aging's guidance on coping with agitation and aggression. For caregivers, agitation is also one of the heaviest parts of the job. A 2024 survey found that families dealing with more agitated behaviors reported significantly higher burden, anxiety, and depression, and these caregivers were already putting in close to 40 hours a week of care, according to a survey reported by the Annals of Long-Term Care.

What Causes Agitation in Dementia
Agitation is rarely random. The National Institute on Aging identifies pain, depression, stress, poor sleep, constipation, a soiled diaper, medication interactions, and overstimulation as the most common underlying triggers, and treating that specific cause often resolves the behavior on its own, per the NIA's guidance. A person with dementia frequently cannot explain what's wrong — they may not recognize their own discomfort or have the words to describe it.
The behavior itself becomes the communication. Checking for the most common physical causes first (a full bladder, tight clothing, hunger, a missed dose of pain medication) is a reasonable starting point before assuming the agitation is simply "the disease." Environmental factors matter just as much. Background noise, visual clutter, too many people in a room, and even an unfamiliar environment can push someone into an agitated state, according to the same NIA guidance. Reducing those triggers — turning off the TV, limiting visitors, simplifying the room — can lower how often episodes occur.
How to Respond in the Moment
When agitation starts, the NIA recommends responding with a calm, steady voice and listening to the person's frustration rather than arguing or trying to reason with them, since logical persuasion rarely works once someone is already agitated, according to guidance reposted by the University of Georgia Caregiver Resource Center. Correcting facts or insisting the person is "wrong" tends to escalate the situation rather than calm it. Offering something familiar can redirect attention away from the source of distress.
A favorite photograph, soothing music, a cherished object, or a short walk outside have all been shown to help de-escalate episodes, per the NIA's agitation guidance. If the behavior turns aggressive — hitting, grabbing, or pushing — the NIA advises staying at a safe distance until it passes and protecting the person from hurting themselves, rather than physically restraining or confronting them, according to the same guidance. Stepping back gives the episode room to run its course without turning it into a physical struggle.
Preventing Episodes Before They Start
Consistency reduces agitation. Keeping bathing, dressing, and meals on the same daily schedule, and building in quiet rest periods between activities, helps prevent agitation from accumulating over the course of a day, according to the NIA.
A predictable routine lowers the number of decisions and transitions a person with dementia has to process, which in turn lowers stress. Unpredictability — a new caregiver, a changed schedule, an unannounced outing — tends to have the opposite effect.
- Keep daily activities (waking, meals, bathing) at consistent times
- Build short rest periods between activities rather than back-to-back tasks
- Limit background noise and the number of people in the room
- Keep familiar objects, photos, or music within easy reach
- Watch for physical discomfort — pain, hunger, a full bladder — before assuming the cause is behavioral
The Toll Agitation Takes on Caregivers
Agitation isn't just hard to manage in the moment — it's one of the main reasons caregiving becomes unsustainable. In the 2024 survey of 250 family caregivers of people with Alzheimer's disease, nearly all care recipients showed at least one agitated behavior, and caregivers facing more frequent agitation reported significantly higher burden, anxiety, and depression, per the Annals of Long-Term Care survey.
Verbal aggression (reported by 28.5% of caregivers), spitting (22.5%), and hitting (18.1%) were the behaviors caregivers found most distressing, and these specific behaviors are commonly cited as factors that push families toward long-term care placement, according to the same survey. Recognizing that these behaviors carry real caregiver-health consequences — not just inconvenience — can make it easier to ask for respite help or additional support sooner rather than later.
When Medication Becomes an Option
On May 11, 2023, the FDA approved brexpiprazole (brand name Rexulti) as the first drug specifically approved to treat agitation associated with Alzheimer's dementia, based on two 12-week randomized, placebo-controlled trials in patients aged 51 to 90, according to the FDA's press release. Rexulti carries the boxed warning shared by other antipsychotic medications: an increased risk of death in elderly patients with dementia-related psychosis.
The most common side effects reported in trials were headache, dizziness, urinary tract infection, nasopharyngitis, and sleep disturbance, per the FDA. Because of that boxed warning, medication is typically considered after non-drug approaches — identifying triggers, adjusting routines, and de-escalation techniques — haven't adequately controlled the behavior. A conversation with the person's prescriber about the specific risks and benefits for their situation is the appropriate next step before starting any new medication.
Frequently Asked Questions
Can agitation in dementia be stopped without medication?
Often, yes. The National Institute on Aging reports that identifying and addressing the underlying trigger — pain, poor sleep, constipation, or overstimulation — frequently stops the behavior without drugs.
What was the first drug approved specifically for dementia-related agitation?
Brexpiprazole (Rexulti), approved by the FDA on May 11, 2023, for agitation associated with Alzheimer's dementia.
Should I physically restrain someone having an aggressive episode?
No. The NIA advises staying at a safe distance and protecting the person from self-injury rather than restraining or confronting them.
