Mood swings, anger, yelling & agitation in dementia: what helps

The shouting is the illness talking, often about fear or pain. You can learn to calm the storm, keep everyone safe and be gentle with yourself afterwards.

By the numbers

How common agitation is, and how hard it is on families.

The person

97%of people with dementia in one large U.S. study had at least one change in behaviour or mood over five years (cited in Kales and colleagues, BMJ, 2015).
Over 50%of people with dementia will have agitation in the middle and later stages of the illness (Hoe and colleagues, BJPsych Open, 2017).
45%of care home residents with moderate or severe dementia had clinically significant agitation in an English study of 86 care homes (Livingston and colleagues, 2017).

The caregiver

59%of dementia caregivers report high or very high emotional stress (Alzheimer’s Association, 2026).
A major reasonAgitation is a major reason families feel unable to keep caring at home, which is why support for carers matters so much (Hoe and colleagues, 2017).

Why anger and agitation happen

It is not on purpose. Tap a card for what is going on inside.

Agitation can look like pacing, fidgeting, crying or repeating the same thing. Anger can be shouting, swearing, threats, pushing or hitting out. It can come out of nowhere, or after a frustrating moment.

The person is not doing this on purpose. Remembering that does not make it hurt less, but it can help you stay steady.
⚡ The brain’s alarm goes offFeeling under threat can trigger “fight or flight”.

Dementia makes it harder to manage strong feelings. If the person believes they are in danger, the part of the brain that handles fear and anger can take over. Their reaction may look out of proportion, but to them the threat feels real.

This is why arguing or explaining rarely works in the moment. Calming the body and the room comes first.

😣 Frustration and embarrassmentNot being understood, or needing help, can sting.
Read more
  • Feeling embarrassed about needing help with washing or the toilet
  • Losing independence, like no longer driving or handling money
  • Not being able to find the right words
  • Not understanding what other people are saying or doing

Anger is often a cover for shame or fear. Protecting the person’s dignity prevents many outbursts.

🫥 Confusion and fearA familiar room or face can suddenly feel strange.
Read more

Not recognising a person or place, or misreading what is happening, can be frightening. Some people also believe things that are not true, such as someone stealing from them, which can lead to angry accusations.

🧭 A need they can’t nameHunger, pain or needing the toilet can come out as anger.
Read more

Because dementia makes it hard to say what is wrong, the behaviour itself becomes the message. Finding the need behind it is often the fastest way to calm things down.

📜 Their life storyOld fears and hurts can surface.
Read more

Past experiences, including trauma such as having been hurt by someone, can shape what feels threatening now. Anniversaries of sad events, touchy topics or seeing someone they have a hard history with can also stir things up.

Knowing their story helps you understand their reactions. Ask relatives what used to frighten or upset them.

Common triggers: body, room and people

Most blow-ups have a trigger. Tap each card to check for it.

Experts say aggressive behaviour is more often caused by something else than by the dementia alone. Checking the body, the room and the way we are talking can uncover a lot.

🤕 PainOne of the most common and most missed causes.
Read more

People with dementia may not be able to say they hurt, so pain can come out as aggression. The next section, “Is it pain? Spotting hidden hurt”, shows the signs to look for.

🦠 Infection, constipation and thirstHidden body problems can change behaviour fast.
Read more
  • Chest infections and urinary tract infections (UTIs)
  • Constipation, which causes cramps and bloating
  • Not drinking enough
  • Wet or soiled underwear or pads
A UTI can cause sudden confusion, called delirium. A sudden change in behaviour needs the doctor quickly.
😴 Tiredness and late afternoonsBeing worn out lowers everyone’s fuse.
Read more

Poor sleep and being overtired make agitation more likely. Many people are calmest in the morning, so plan baths, outings and appointments then.

The Dementia: changes in behaviour guide has a full plan for sundowning and nights.

📢 Too much going onNoise, crowds and clutter can overwhelm.
Read more
  • A busy family gathering or a crowded shop
  • Clutter and glare
  • Loud TV, radio or several people talking at once
  • Unfamiliar people, even at home

Too little going on can be a trigger too. Boredom and having nothing to do can build restlessness.

🛁 Personal careWashing and dressing are common flashpoints.
Read more

Being undressed or touched by someone, even a loved one, can feel frightening or shaming. Fear or distress during washing can also be a sign of pain.

What can help

  • Explain each step before you touch them
  • Keep them covered and warm with a towel
  • Let them do what they still can
  • Try again later if they refuse
🔄 Changes in routineNew places, people or plans can unsettle.
Read more

Travel, a hospital stay, houseguests, a new caregiver or a move can all bring on agitation. Even a change in the order of the day can throw someone off.

🗣️ How we talk to themThey pick up on our stress, even without words.
Read more

Too many questions at once, rushing, or a sharp or irritated tone can set off a reaction. People with dementia often read our faces and voices more than our words.

This is not about blame. Every caregiver gets tired and snappy. It just means one of the triggers is something you can change.

Is it pain? Spotting hidden hurt

People with dementia feel pain but may not be able to say so.

Some people believe people with dementia don’t feel pain. They do. They may just not be able to recognise it, describe it or point to where it is. Fear and confusion can even make pain feel worse.

Signs that may mean pain

  • Calling out, groaning or shouting, especially if this is new
  • Fear, distress or hitting out during washing or dressing
  • Fidgeting, restlessness or agitation
  • Grimacing, frowning or a tense face
  • Holding or guarding one part of the body
  • Not wanting to move, or showing discomfort when moving
  • Off their food, or sleeping more or less than usual
  • Seeming low, withdrawn or unusually quiet

How to check

  1. Ask simple, specific questions: “Does it hurt here? Is your arm aching? Does it sting?”
  2. Think back: how did they act when they were in pain before?
  3. Look for causes such as sore gums or teeth, stiff joints, a fall, constipation or a UTI.
  4. Write down when it happens, how often, and what seems to bring it on.
  5. Take your notes to the doctor or nurse.
A person may say “no” when asked if they are uncomfortable, even when they are. Or they may use the wrong word for what they feel. Watch their face and body as well as their answer.

Gentle movement through the day, good cushions and support in a chair, and a gentle hand massage can ease everyday aches. If you think they need pain relief, talk with their clinical provider.

In the moment: calm responses that help

What to do, how to stand and what to say when tempers rise.

When agitation starts to build

  1. Breathe. Slow your own body down first.
  2. Lower your voice. Speak slowly, softly and steadily, even if they are shouting.
  3. Respond to the feeling, not the facts: “You seem really upset.”
  4. Reassure: “You’re safe. I’m here to help.”
  5. Quickly check for a need: pain, toilet, hunger, thirst, too hot or cold.
  6. Make the room calmer: turn off the TV, ask others to step out.
  7. Offer something soothing, or give them space.
🧍 Your body languageLook calm and non-threatening.
Read more
  • Keep your arms loose and your hand movements small
  • Move slowly and stay where they can see you
  • Sit down if they sit, so you aren’t standing over them
  • Stand about an arm’s length away, turned slightly sideways
🚫 What to avoidThese tend to make things worse.
Read more
  • Arguing, correcting or trying to reason
  • Cornering, crowding or holding them back
  • Criticising or showing alarm or offence
  • Ignoring them, or making sudden moves
  • Matching their volume or tone
💬 Try saying…Short, warm phrases you can repeat.
Read more
  • “I can see this is upsetting. I’m here.”
  • “I’m sorry if I upset you. I’m here to help.”
  • “I will stay until you feel better.”
  • “Let’s take a break and have a cup of tea.”
  • “You’re safe here.”
Pick one or two phrases and use the same ones every time. Familiar words can be soothing in themselves.
⏸️ Giving them spaceSometimes stepping away is the kindest thing.
Read more

If the person is safe, leave the room and come back in 10 to 15 minutes to see how they are. A short break also gives you a moment to recover.

If they are upset because they don’t recognise someone, it may help for that “stranger” to leave the room for a while.

When they yell, swear or call you names

Hurtful words from someone you love. How to respond and not take it in.

Verbal aggression, like shouting, swearing and name-calling, is one of the most common forms of aggression in dementia. Changes in the brain can loosen the filter a person had all their life, so they may say things they never would have before.

🛡️ It’s not really about youThe words come from distress, not their true feelings.
Read more

Insults often land on the closest person, which is usually the main caregiver. Try to hear the words as a sign of distress, the same way you would hear a cry.

Even knowing this, hurtful words still hurt. It is okay to feel shaken, and to talk to someone about it later.
❤️ Look for the feeling underneathFear, frustration, boredom or pain.
Read more

Instead of… try…

  • Instead of “Don’t talk to me like that!”, try “You sound really frustrated.”
  • Instead of “You know that’s not true”, try “That sounds frightening. Let’s sort it out together.”
  • Instead of “Calm down!”, try “I’m here. Let’s sit down a minute.”
🔁 Repeated shouting or calling outCheck for pain, boredom and fear.
Read more

Shouting or groaning that is new or getting worse can be a sign of pain. Calling out over and over can also come from boredom, loneliness or not knowing where you are.

Ideas to try

  • Leave a note or say where you’ll be: “I’m in the kitchen”
  • Offer company, a familiar voice or music
  • Offer something for their hands to do
👥 In public or with visitorsMove somewhere quieter and keep it simple.
Read more

Busy places and big gatherings can overwhelm. If an outburst starts, help the person move to a calmer spot. A quiet word to others, such as “My dad has dementia”, is usually enough.

Redirecting and calming activities

Gently steer attention to something soothing. Tap a card for ideas.

Once the person feels heard, gently move their attention to something pleasant. Family carers say familiar hobbies, music and simple tasks can head off agitation or interrupt it.

🎵 MusicFavourite songs can soothe fast.
Read more

Music, gentle massage and exercise are among the relaxing activities experts suggest when someone is upset. Play songs from their younger years, quietly.

🚶 A walk or fresh airMovement uses up restless energy.
Read more

A walk, time in the garden or sitting outside can release tension. Regular walks during the day help prevent restlessness later.

🧺 A simple, useful taskFeeling helpful can be calming.
Read more
  • Folding towels or socks
  • Sorting buttons, cards or photos
  • Watering plants
  • Wiping the table
🍪 A snack or drinkHunger and thirst are common hidden triggers.
Read more

Offering a favourite snack or a drink meets a possible need and gives a natural change of focus.

🧸 Comfort and touchA hand to hold or a familiar object.
Read more

Reassuring touch, affection and a comfort object can ease distress, even when you can’t find the cause. Only offer touch if they are calm enough to welcome it.

📺 A familiar show or photosFamiliar and gentle, not the news.
Read more

A favourite TV show or a photo album can help. Avoid the news or anything violent or upsetting, since it may seem to be happening in the room.

What works on Monday may not work on Tuesday. Keep a short list of three or four go-to ideas and rotate them.

Safety when it escalates

Keeping you, them and others safe, during and after an episode.

Sometimes, even with the best care, things get physical. Having a plan ahead of time helps you feel more in control and keeps everyone safer.

🏠 Make the home saferRemove what could be used to hurt.
Read more
  • Cover or remove mirrors if they mistake their reflection for an intruder
  • Keep exits and hallways clear of clutter
  • Lock away car keys, guns, knives, scissors and tools
🧭 During an episodeProtect yourself without making it worse.
Read more
  • Keep a clear path to the door, and stand nearest to it
  • Put a table or bed between you if you need a barrier
  • Stay an arm’s length away, turned slightly sideways
  • Step back to a safe distance until it passes
  • Don’t travel in the car with them until they are calm
If they are set on leaving the house, trying to stop them can lead to someone getting hurt. It is often safer to let them go and follow at a distance, or call a neighbour, relative or the police for help.
📱 Your personal safety planDecide now, so you don’t have to think later.
Read more
  • A code word for family and friends that means “I need help now”
  • A “go bag” with a spare key, phone charger, snacks and important numbers
  • A room you can go to and lock, such as the bathroom
  • A charged phone you can reach

Use the “My safety plan” worksheet to write this down.

🌤️ AfterwardsLet things settle. Don’t replay it.
Read more
  • Check whether anyone is hurt and get medical help if needed
  • Keep the room calm and quiet, and your voice low
  • Give the person time. Stress hormones can take 20 to 30 minutes or more to settle
  • Expect them to be easily upset again for the next few hours
  • Don’t remind them what happened or tell them off. It rarely helps
  • Later, think about what set it off and what you can change
👧 If children live in the homeKeep them safe and let them talk.
Read more

Normal noisy play can sometimes trigger distress. Make sure another adult is close by if there is any risk, and teach children to move away to a safe room if they feel worried or frightened.

Let children tell you what they find hard, and let their school know what is happening. The Sharing dementia care: family, kids & care staff guide has more.

If anyone is in danger, call 911 and tell them the person has dementia, which can cause aggressive behaviour.

Preventing the next blow-up

A four-step way to find patterns and make a plan.

Dementia specialists use a step-by-step approach called DICE: Describe, Investigate, Create, Evaluate. Families can use the same steps at home, together with the care team.

DICE at home

  1. Describe: write down who, what, when and where. What happened just before? What upset the person, and you, the most?
  2. Investigate: look for causes you can change, like pain, infection, constipation, sleep, the room or how things were said.
  3. Create: make a plan with the care team, such as a new routine, simpler steps or a calmer space.
  4. Evaluate: after a week or two, ask what helped, what didn’t, and how you are coping.

Everyday habits that prevent outbursts

  • Break tasks into small steps and don’t rush
  • Explain what you’re about to do before you start
  • Keep a steady daily routine, with quiet times built in
  • Let them make as many choices as they can
  • Plan harder tasks for their best time of day, often the morning
  • Agree on one calm approach with everyone who helps care
The “Behaviour detective log” worksheet in the Dementia: changes in behaviour guide is a good way to do the Describe step. Use the “Our warning signs & calm-down plan” worksheet here for the Create step.

When you feel like yelling back

Your anger and guilt are human. Here is how to cope with them.

Being shouted at, blamed or hit by someone you love is exhausting. Many carers say agitation is the hardest part of caring, and some feel they can’t go on. Feeling angry, scared or resentful does not make you a bad person.

🌬️ In the heat of the momentCalm yourself first.
Read more
  • Count to 10 and take slow, deep breaths
  • Say to yourself: “This is the illness, not them.”
  • If they are safe, step out of the room for a few minutes
😔 If you snappedRepair, forgive yourself and learn.
Read more

Every carer loses their temper sometimes. Once things are calm, a simple “I’m sorry, I love you” is enough. The person may not remember, but the warmth helps you both.

If you notice you are snapping more often, treat it as a sign you need more rest and help, not as a failure.

🗨️ Talk to someone“Talk; the biggest advice: talk.”
Read more

That was one carer’s advice in a study of families coping with agitation at home. Carers found that friends, family, support groups and breaks made them calmer and better able to care.

If you often feel frustrated or angry, talk with a doctor, counsellor or trusted friend.

🛌 Get real breaksRest is part of good care.

If you ever fear you might hurt the person, or yourself, reach out now. Call or text 988, or text HOME to 741741. It is a sign of strength to ask for help.

When and where to get help

When to call the doctor, 911 or a helpline.

Call the doctor or care team soon if

  • Anger, agitation or aggression is new, sudden or getting worse
  • You see signs of pain, a fever or an infection
  • They seem much more confused than usual
  • There has been a recent change in their treatment
  • Your usual calming ideas have stopped working
Sudden confusion or a sudden change in behaviour, especially with a fever or infection, needs a doctor right away. It may be delirium, a medical problem that can often be treated.

Bring your notes. Ask the doctor to check for pain, infection, constipation and other body causes, and ask whether a dementia specialist team could help. Talk with the clinical provider about any treatment options.
