Anger and irritability in later life

Being "cranky" is not a normal part of getting older. In fact, problem anger is more common in younger adults than in older ones.¹ So when an older person becomes short-tempered, critical or easily upset, it is worth asking why.

Often there is a reason that can be found and helped, such as pain, hearing loss, a medicine, depression or the early changes of dementia. This page explains those causes, how anger and agitation show up in dementia, and how family caregivers can handle their own anger and guilt.

Is anger a normal part of aging?

No. In a national survey of more than 34,000 U.S. adults, anger that was out of place, very intense or poorly controlled was more common in younger adults.¹

Anger may also weigh more on health in very old age. A study of 226 adults aged 59 to 93 tracked their feelings for a week. In people 80 and older, more daily anger was linked with more inflammation (a sign of the immune system being on alert) and more chronic illness. This link did not appear in people aged 59 to 79, and sadness was not linked to either.² The authors suggested that anger may become more harmful when losses can no longer be undone. They also noted that therapy and education can help older adults cope with change.²

Common causes of irritability in later life

Pain

Long-term pain from arthritis, back problems or nerve damage can wear down anyone's patience. A review of 38 studies found that people with chronic pain who had more anger also tended to report more pain and disability. Feeling that the pain was unfair was strongly linked to worse outcomes.³ Treating pain well can make a real difference. See Chronic pain and mood.

Hearing loss

About 1 in 3 older adults has hearing loss.⁴ Missing what people say is frustrating and embarrassing. People with hearing loss may pull back from others, and others may wrongly think they are confused or uncooperative.⁴ That can feed irritability on both sides. A hearing test and hearing aids may help. See Hearing loss and loneliness and Hearing in later life.

Loss of independence

Giving up driving, moving out of a longtime home, or needing help with daily tasks can bring grief and anger. The National Institute on Aging lists a sense of loss, such as losing the freedom to drive, among the common triggers of agitation in people with dementia.⁸ Similar losses can upset anyone. See Moving and downsizing and Retirement and mental health.

Depression

Depression does not always look like sadness. It can show up as irritability, frustration and more anger than usual.⁷ Older adults with depression may also feel numb or flat rather than sad.⁷ Depression is treatable at any age. See Depression in later life.

Medicines

Many older adults take several medicines, and some can affect mood. For example, levetiracetam, a common seizure medicine, can cause irritability and aggression. Its patient information warns families to call the doctor right away about angry or violent behavior.⁵ Bring all your medicines, including over-the-counter products and supplements, to your doctor or pharmacist for a review. Talk with them before changing anything. See Medicines and mood.

A sudden change: delirium

Delirium is a sudden, severe state of confusion. It can come with anger, agitation, irritability or other personality changes, and alertness can swing from sleepy to agitated and back.⁶ Common causes include infections (such as urinary or lung infections), some medicines, alcohol, and surgery.⁶

Other causes

Poor sleep, alcohol, loneliness and early changes in the brain can also play a part. See Sleep in later life, Alcohol and older adults and Loneliness in later life. A big change in personality after age 60 should always be checked by a doctor.

Agitation and anger in dementia

People living with dementia may become restless, upset or aggressive. They may yell, curse, push or hit. Often this is how a person shows discomfort they cannot put into words.⁹ It is very hard on families.

Most of the time, agitation and aggression happen for a reason.⁸ Common causes include:^8,9

• Physical discomfort: pain, constipation, infections such as a urinary tract infection, hunger, thirst, tiredness or medicine side effects
• Surroundings: too much noise, clutter or too many people, or a sudden change in routine, place or caregiver
• Hard tasks: being pushed to do things that have become very hard, such as bathing
• Communication: complicated instructions, too many questions at once, or sensing a caregiver's stress
• Loss and loneliness: a sense of loss, such as no longer driving, or too little contact with others

What helps in the moment

• Stay calm. Speak slowly and softly, and reassure the person.⁹
• Focus on the feeling behind the words, not the facts. Do not argue.^8,9
• Check for pain and other needs, such as hunger or thirst.⁹
• Lower noise and clutter.⁸
• Shift to something soothing, such as music, a snack, a walk or a simple chore like folding laundry.⁸
• Take a break if the person is safe and you can step away.⁹

Preventing the next episode

Keep a steady daily routine, get daylight, stay active, and limit caffeine and long naps late in the day.⁸ Write down what happened just before each outburst to spot patterns.⁹ Our behavior diary can help. Ask the doctor for a medical exam to look for physical causes.⁸

Medicines for agitation

Talk with the doctor if aggressive behavior gets worse. Medicine may help in some cases.⁸ The FDA has approved medicine for agitation linked to Alzheimer's disease. In April 2026, it approved the first such medicine that is not an antipsychotic.¹⁰ Every option has risks. See Medicines for agitation in dementia.

Caregivers' own anger and guilt

If you care for a spouse or parent, you may feel angry, frustrated, guilty or resentful at times. These feelings are a normal part of caring for someone who needs help day after day.¹¹ Anger often rises when the person resists help, or when dementia makes them hard to reason with. Resentment can grow when other family members do not pitch in.¹¹

You are not alone. In a study of 220 family caregivers of people with dementia, about half said they had sometimes acted in ways that could count as abuse, mostly yelling, shouting or insulting. About 1 in 3 reported this at a level the researchers considered important. Physical abuse was rare.¹² Findings like these are a signal that caregivers need more support, not more blame.

The Family Caregiver Alliance suggests:¹¹

• Forgive yourself. Everyone loses patience sometimes.
• Take a time-out. Walk away for a few minutes when you feel anger rising, if the person is safe.
• Talk with someone who will listen without judging, such as a friend or support group.
• Think of guilt as regret. Hard choices are part of caregiving. Regret admits that without punishing yourself.
• Accept help and take regular breaks. Respite care and adult day programs restore patience and energy.
• Hold a family meeting to share the load.

Calming practices such as cyclic sighing and loving-kindness can help, too. See Caregiver stress in dementia, Caregiver burnout, Respite care and Adult day care.

What helps

• Get a checkup. Ask the doctor to look for pain, hearing or vision problems, infections, sleep problems, depression and medicine side effects.
• Treat what you find. Better pain care, hearing aids or a medicine change can ease irritability.
• Keep routines and connection. Regular meals, sleep, activity and contact with others steady mood.
• Learn anger skills. They can be learned at any age. See Self-help for anger and Treatment for anger problems.
• Find a specialist if needed. See Geriatric psychiatry.

Common questions

Is my father just getting grumpy with age?

Maybe not. Problem anger is less common in later life than in young adults.¹ A change in temper can be a sign of pain, hearing loss, depression, a medicine side effect or early dementia. A checkup is a good first step.

Should I correct my mother when she is wrong?

If she has dementia, arguing about facts usually makes things worse. Respond to the feeling instead. For example, "That sounds frightening. I am here."^8,9

When to get help

• Call the doctor the same day for a sudden change in behavior, confusion or alertness.⁶
• Make an appointment if irritability lasts more than a couple of weeks, or comes with low mood, poor sleep or memory problems.
• Call 911 if anyone is in danger.
• Call or text 988 if you or the person you care for has thoughts of suicide.
