Treating Agitation in Alzheimer’s Disease

Agitation is one of Alzheimer’s most exhausting “bonus features” (0/10, do not recommend). It can look like pacing, restlessness, yelling, repeated questions, resistance to care, or sudden irritability. And it’s not just hard on the person living with Alzheimer’sit can drain caregivers faster than a phone with 1% battery.

Here’s the hopeful part: agitation is often a form of communication. When words get harder, the brain uses behaviors to say, “Something is wrong.” The most effective treatment usually starts by translating the messagethen adjusting the environment, routine, communication style, and (when truly needed) medication.

What Agitation Is (and What It Isn’t)

Agitation is a cluster of behaviors that signal emotional distress, excess motor activity, or difficulty tolerating a situation. It may include:

• Pacing, fidgeting, repetitive movements
• Verbal outbursts, shouting, crying, repeated requests
• Resistance during bathing, dressing, or toileting
• Anger, irritability, or “being on edge”

Agitation is not the same as “bad attitude.” Alzheimer’s changes how the brain processes sensation, stress, and language. Sometimes the person is overwhelmed, scared, in pain, or confusedeven if they can’t explain it. The goal is not to “win” the moment. The goal is to reduce distress and keep everyone safe.

Why Agitation Happens in Alzheimer’s

Agitation is often triggered by one (or several) of these categories:

1) Physical discomfort

Pain is a big oneespecially because Alzheimer’s can make it hard to report pain clearly. Hunger, thirst, constipation, urinary tract infections, dental problems, skin irritation, or medication side effects can all show up as agitation.

2) Environmental overload

Noise, glare, clutter, background TV, crowds, or too many people talking at once can overwhelm a brain that’s already working overtime. What feels “normal” to you can feel like a packed airport terminal to them.

3) Communication mismatch

If the person can’t understand instructions or express needs, frustration can spike fast. Complex questions (“What do you want for dinner?”) can feel like a pop quiz with no right answers.

4) Routine disruption and fatigue

Changes in schedule, unfamiliar settings, caregiver swaps, late-day tiredness, and “sundowning” (worsening confusion or agitation later in the day) can all contribute.

5) Emotional distress

Fear, loneliness, grief, depression, anxiety, or simply not recognizing where they are can trigger agitation. The feeling is realeven if the story behind it isn’t.

Step 1: Rule Out Medical Causes (Before You Treat the Behavior)

If agitation is new, suddenly worse, or out of character, think “body first.” A quick medical check can prevent weeks of misery (and unnecessary meds).

Red flags: call a clinician soon (or urgently)

• Sudden onset or rapid worsening over hours/days
• Fever, cough, urinary symptoms, dehydration signs
• New pain, falls, new confusion beyond baseline
• New medication or dose change (including OTC sleep aids)
• Hallucinations/delusions that are frightening or dangerous
• Any threat of harm to self/others, or inability to safely manage at home

A practical “comfort checklist” (fast and surprisingly effective)

• Pain: arthritis, headache, tooth pain, sore feet, pressure areas
• Bathroom: constipation, urinary urgency, accidents, discomfort
• Food/water: hunger, thirst, blood sugar dips
• Temperature: too hot/cold; sweaty clothing
• Fatigue: overstimulation, too many errands, too late in the day
• Sensory issues: hearing aids/glasses missing, too much noise/light

Caregiver tip: If you fix one thing and agitation improves, you didn’t “get lucky.” You ran a good experiment.

Step 2: Non-Drug Strategies That Actually Work (First-Line Treatment)

Major reviews and caregiver organizations consistently recommend nonpharmacologic (non-drug) approaches as the starting point for agitation in dementia. They can reduce episodes, shorten duration, and lower caregiver distresswithout medication risks.

Create a calm environment (less “input,” more comfort)

• Reduce noise and competing stimulation (TV as background music is still noise).
• Soften lighting; reduce glare and harsh shadows.
• Declutter high-traffic spaces; simplify the visual field.
• Use familiar objects and photos for reassurance.
• Keep items they need easy to find (bathroom signs, night lights).

Build a predictable routine (the brain loves fewer surprises)

• Keep wake, meals, and bedtime consistent.
• Schedule hard tasks (bathing, appointments) earlier in the day.
• Use short, repeatable rituals (tea after lunch, music before bed).

Upgrade communication (simple changes, big payoff)

• Approach from the front, make eye contact, and speak calmly.
• Use short sentences and one-step instructions.
• Offer two choices max (“blue shirt or green shirt?”).
• Validate feelings before redirecting (“That sounds scary. I’m here.”).
• Avoid arguing or correcting (“Actually, it’s 2026”)it rarely helps.

Use meaningful activity (purpose beats boredom)

Agitation often rises when the person has excess energy and nowhere to put it. Helpful options include:

• Light exercise: short walks, chair stretches, dancing in the kitchen
• Simple tasks: folding towels, sorting socks, wiping the table
• Reminiscence: photo albums, familiar stories, “tell me about…” prompts
• Music: playlists from their teens/20s (often a sweet spot)
• Outdoor time: fresh air and a change of scenery

Specific example: If your loved one paces every day at 5 p.m., try a 10–15 minute walk at 4:30, followed by a snack and calming music. You’re not “distracting them”you’re meeting a predictable need.

Track triggers with an ABC log (simple, nerdy, powerful)

Use the ABC method:

• A = Antecedent: What happened right before? (noise, bath time, hunger, visitors)
• B = Behavior: What did agitation look like? (yelling, pacing, pushing away)
• C = Consequence: What happened after? (they got attention, the task stopped, they ate)

Patterns show you what to change. If agitation reliably follows shower time, the “treatment” may be changing the shower approachnot adding a sedating medication.

Step 3: What to Do During an Agitation Episode (De-Escalation)

When agitation spikes, your job is to lower emotional temperature, not deliver a TED Talk. Think: calm, safe, simple.

De-escalation steps

1. Pause and breathe. Your nervous system is contagious.
2. Reduce stimulation. Turn off TV, lower lights, move to a quieter room.
3. Use a calm voice. Short phrases: “You’re safe. I’m here.”
4. Validate, then redirect. “You seem upset. Let’s sit and have some water.”
5. Offer comfort needs. Bathroom? Snack? Pain relief plan? Warmer sweater?
6. Give space. Too much “helping” can feel like pressure.

Do / Don’t list (print this in your brain)

• Do keep your face relaxed and your tone low.
• Do use reassuring touch only if it’s welcome.
• Do step back if the person feels cornered.
• Don’t argue, lecture, or demand explanations.
• Don’t take insults personally (Alzheimer’s is a rude editor).
• Don’t “trap” them with too many words or choices.

Mini-script: “It looks like something is bothering you. We can take a break. Let’s sit here together.”

Step 4: When Medication May Be Appropriate (and How to Think About It)

Medication is not “failure.” But because drugs for agitation can carry serious risksespecially in older adultsmost clinical guidance treats them as second-line, used when:

• Agitation causes danger (risk of injury to the person or others), or
• Agitation causes severe distress that does not improve with non-drug strategies, and
• Medical causes (pain, infection, medication side effects, delirium) have been addressed.

Medication principles that keep people safer:

• Use shared decision-making (benefits vs. risks).
• Start low, go slow, reassess often.
• Use the lowest effective dose for the shortest time possible.
• Plan for tapering when stable, when appropriate.
• Monitor for sedation, falls, blood pressure changes, movement symptoms, and metabolic effects.

Medication Options: What the Evidence Says

Brexpiprazole (Rexulti): an FDA-approved option for agitation in Alzheimer’s dementia

In 2023, the FDA approved brexpiprazole (Rexulti) as the first medication specifically indicated for treating agitation associated with dementia due to Alzheimer’s disease. Dosing is typically titrated upward over time (for example, starting at a low daily dose and increasing to a target dose based on response and tolerability).

Safety note: Like other antipsychotics, brexpiprazole carries a boxed warning about increased mortality in older adults with dementia-related psychosis. That doesn’t mean it can’t be usedbut it does mean it must be used thoughtfully, with careful monitoring and a clear reason for taking on the risk.

Other antipsychotics (often off-label): limited benefit, real risks

Clinicians sometimes use antipsychotics such as risperidone, olanzapine, quetiapine, or aripiprazole off-label for severe agitation or aggression. Evidence suggests they can help some people, but the average benefit is modestand risks include sedation, falls, stroke risk in some populations, movement disorders, and increased mortality (the reason for boxed warnings).

Professional guidance (including psychiatric practice guidance) generally recommends antipsychotics only when symptoms are severe, dangerous, or extremely distressing, after non-drug measures, and with ongoing reassessment and attempts to taper when appropriate.

SSRIs (like citalopram): may help some people, but dosing matters

The SSRI citalopram has evidence for reducing agitation in Alzheimer’s in a notable randomized trial, but higher doses were associated with concerns like QT interval prolongation (a heart rhythm risk) and cognitive side effects. In practice, if an SSRI is considered, clinicians typically weigh heart risks, other medications, and may use more conservative dosing and monitoring.

Dextromethorphan-quinidine: promising trial data, still a careful decision

A randomized clinical trial found that dextromethorphan-quinidine demonstrated clinically meaningful improvement in agitation over a short study period and was generally tolerated. However, it can interact with other medications and may not be appropriate for everyoneso it’s a clinician-guided decision, not a DIY fix.

Other medications sometimes used (evidence varies)

• Trazodone: sometimes used when insomnia and nighttime agitation overlap; sedation and fall risk matter.
• Gabapentin: occasionally used when pain/anxiety components are suspected; can cause dizziness/sedation.
• Benzodiazepines: generally avoided for ongoing agitation in dementia because they can worsen confusion and increase falls, though they may be used in specific short-term situations under medical supervision.

Putting It Together: A Simple Treatment Plan Template

Week 1: Observe and stabilize

• Start an ABC log for 7 days.
• Run the comfort checklist twice daily (pain, bathroom, food/water, fatigue).
• Reduce environmental triggers (noise, glare, clutter).

Week 2: Add structured calming routines

• Daily movement (walk, stretching, dancing).
• Music routine (same playlist at the same time each day).
• Plan difficult care tasks earlier in the day; simplify steps.

Week 3: Target the biggest trigger

Pick the most predictable trigger from your log (bathing, evening hours, visitors, hunger) and redesign it. Example: switch to sponge baths, warm towels, and a two-step process; or limit visitors to one at a time for shorter visits.

Medication discussion (if needed)

If severe agitation persists despite solid non-drug work and medical causes have been addressed, discuss options with the clinician. Ask:

• What problem are we targeting (danger, distress, sleep, pain)?
• What’s the expected benefitand how soon?
• What are the key risks for this person (falls, stroke risk, heart rhythm, drug interactions)?
• How will we monitor and when will we reassess?
• What’s the taper/stop plan if stable?

Real-World Experiences: What Caregivers Often Notice

Caregivers often describe agitation as the symptom that “changes the whole house.” Not because the person becomes a different humanbut because everyone’s nervous system starts walking on eggshells. Across many families, a few patterns show up again and again.

1) “It’s always worse at the same time.”
One caregiver might notice agitation spikes around late afternoon: pacing, repetitive questions, and a tone that says, “I don’t know what I need, but I need it now.” What’s happening isn’t laziness or dramait’s often a mix of fatigue, changing light, hunger, and a brain that’s losing its ability to interpret shadows and noise. Families who do best here tend to treat 4–7 p.m. like a predictable weather event: they prepare. A snack at 3:30, a short walk at 4:30, brighter lighting as the sun drops, fewer visitors, and familiar music can take the edge off. It’s not magic. It’s planning.

2) Bathing is a common “agitation hotspot.”
Many people with Alzheimer’s become distressed during bathing. Caregivers often assume it’s stubbornness. But imagine someone you don’t fully recognize telling you to undress, step into a cold room, and let water hit your face while you’re confused. That’s not relaxingit’s a thriller movie. Small changes can help: warming the bathroom, using big towels, explaining each step in simple language, offering a choice (“wash face or hands first?”), and keeping a calm pace. Some caregivers switch from showers to sponge baths or reduce bathing frequency while maintaining hygiene with wipes and targeted cleaning. The win isn’t “perfect bath time.” The win is “less fear.”

3) Pain often hides behind the behavior.
Caregivers frequently report that agitation improved once they treated something physical: an infected tooth, constipation, a urinary infection, or arthritis pain that flared after a long day. The lesson many families learn the hard way: when speech fades, pain can show up as yelling, pushing away, or refusing care. Families who adopt a routine “pain check” (watching for grimacing, guarding a body part, changes in walking, or agitation during movement) often catch problems earlier. It’s one of the most practical ways to reduce agitation without adding psychiatric meds.

4) The caregiver’s tone matters more than the caregiver’s logic.
People living with Alzheimer’s may forget words, dates, and even facesbut they often remain sensitive to emotional cues. Caregivers commonly notice that when they speak faster, correct more, or show frustration, agitation escalates. When they slow down, soften their voice, and validate feelings first, episodes shorten. Many caregivers describe a mental shift: instead of trying to “fix the facts,” they try to “fix the feeling.” That doesn’t mean agreeing with delusions. It means responding to the emotion underneath: “That sounds scary. I’m with you.”

5) Small routines create big stability.
Caregivers often find that agitation decreases when the day becomes more predictable. A short morning walk, lunch at a consistent time, a familiar afternoon activity (folding towels, sorting cards, watering plants), then the same calming music before dinnerthese routines become anchors. When routines break (appointments, visitors, noisy repairs), agitation often rises. Families who plan “recovery time” after disruptionsquiet, snack, rest, familiar musicoften regain calm faster.

6) Medication can help, but it’s rarely the whole answer.
Some caregivers report meaningful improvement when a clinician carefully introduces or adjusts medicationespecially when agitation creates safety risks. But many also say that medication works best when paired with environment changes, routines, and better communication. The most realistic expectation is not “zero agitation forever.” It’s fewer episodes, lower intensity, and quicker recoveryplus safer days for everyone involved.

Caregiver reality check (and permission slip): You’re allowed to take breaks. Respite care, support groups, and rotating help aren’t luxuriesthey’re durability tools. Agitation is hard. A supported caregiver is a safer caregiver.

Conclusion

Treating agitation in Alzheimer’s disease works best when you treat it like a clue, not a character flaw. Start by ruling out medical causes like pain or infection, then reduce triggers through calmer environments, predictable routines, and simpler communication. Use de-escalation in the momentvalidate feelings, lower stimulation, and meet basic needs. Medication may be appropriate for severe distress or safety risks, but it should be chosen carefully, monitored closely, and paired with non-drug strategies whenever possible.
