Caring for someone who is confused and agitated | CION Cancer Clinics
When someone with cirrhosis or liver cancer becomes confused, angry or stubborn, the liver is often the cause, and it is usually treatable. They are not going mad. This page explains what you may see at home, how to calm the moment, what to check, and the signs that mean going to hospital today rather than waiting for the morning. At CION Cancer Clinics, our team supports patients and families through symptoms, follow-up and life during and after treatment.

The short answer
Why is my father suddenly confused, angry or stubborn?
When someone with cirrhosis or liver cancer becomes confused, restless or unusually difficult, the cause is very often the liver, not the mind. A weak liver cannot clear certain toxins from the blood, and they reach the brain. Doctors call this hepatic encephalopathy, which simply means the brain is affected by the liver.
It is treatable, and it often reverses
This is the most important thing a family can know. Many people return to their usual selves once the trigger is found and treated. Families often say the person is "going mad" or "becoming stubborn", and take them to a psychiatrist or a neurologist first. The right first call is the doctor treating the liver or the cancer.
Who this page is for
This page is for the family member or carer at home. It covers what you may see, what to do in the moment, and when to go to hospital. If confusion has started for the first time and nobody has explained why, read why the liver affects the brain as well. It does not apply to confusion after a fall or head injury, which needs emergency care whatever the liver is doing.
The person is not choosing to behave this way. The behaviour is a symptom, in the same way jaundice is.What families notice
What does liver-related confusion look like at home?
It rarely arrives all at once. Families usually notice small changes first, and only later see that they were connected.
Sleep turns upside down
Dozing through the day and lying awake or wandering at night is one of the earliest signs. See sleeping all day and awake all night.
Mood and temper change
Irritability, suspicion, tearfulness or sudden anger at people they love. Some people become unusually quiet and flat instead.
Thinking slows down
- Forgetting what was said a minute ago
- Muddling dates, money or medicines
- Slow, slurred or rambling speech
- Handwriting becoming untidy
Physical signs
A shaking or flapping of the hands when the arms are held out, clumsiness, and a sweetish, musty smell on the breath. Increasing drowsiness is the sign to take most seriously.

When to go to hospital today
Go to hospital today if the person is hard to wake, cannot recognise family, is newly confused and has a fever, has vomited blood or passed black stools, has fluid in the abdomen with pain or fever, or has stopped eating and drinking. Do not wait to see if it settles by morning. Take the list of medicines and the latest reports with you. See when confusion needs hospital admission.
In the moment
What should I do when they are agitated and will not listen?
Keep your own voice low
Speak slowly, in short sentences, one request at a time. Arguing or correcting every wrong statement usually makes agitation worse. Agree where it does no harm.
Make the room calm and safe
Reduce noise and visitors. Keep a dim light on at night. Move sharp objects, gas knobs and vehicle keys out of reach. See driving, cooking and safety at home.
Check the bowels and the medicines
Constipation is a common trigger. Ask whether the person has passed stools today and whether lactulose doses were missed or refused. Do not give sleeping tablets or sedatives the doctor has not prescribed for this.
Call the treating team
Describe what has changed and since when. The team will tell you whether to adjust medicines at home or come in. If you cannot reach anyone and the person is getting drowsier, go to hospital.
Commonly believed
Four things families believe about liver confusion
"He has gone mad. We need a mental hospital."
The brain is being affected by toxins the liver cannot clear. This is a medical problem with medical treatment, and it is usually handled by the liver or cancer team. A psychiatrist is rarely the right first stop.
"Stop giving him protein, it is poisoning his brain."
This was old advice and it has changed. Most people with cirrhosis need enough protein to keep their muscles, and cutting it can do harm. Read should protein be reduced? and ask the team before changing the diet.
"The loose motions from lactulose mean it is not suiting her."
Soft, regular motions are how lactulose works. Stopping it because of the motions is one of the commonest reasons confusion comes back. Tell the doctor if the diarrhoea is heavy, rather than stopping on your own.
"Once the confusion starts, it only gets worse."
Many episodes have a clear trigger, such as an infection, constipation, bleeding or a new medicine. When the trigger is treated, the person often returns to how they were.
Leave a number, we will call you
One field. No form to fill in, and no charge for the call.
For the carer
How do I cope when the person I love does not seem like themselves?
It is painful to be shouted at, accused or not recognised by a parent or a spouse. Remind yourself that the illness is speaking, not the person. Most people remember little of what they said during an episode, and many are embarrassed when told.
Share the load
In joint families, one person often carries the nights alone. Make a simple rota, so somebody rested is always awake. Keep one written sheet on the fridge with the medicines, the treating doctor and the signs that mean hospital. An emergency plan for the fridge helps anyone who is on duty.
Ask for support early
At CION centres, supportive and symptom care is part of treatment, and the team can help you plan for episodes before they happen. Liver specialist care, including hepatology review, is coordinated through partner hospitals when it is needed. Carers who are exhausted make more mistakes with medicines, so asking for help is part of good care.
Feeling angry, tired or guilty as a carer is common. It does not mean you are failing.Being straight with you
What this page cannot tell you
It cannot tell you whether your relative's confusion is caused by the liver. Confusion can also come from infection, low sugar or low salt levels in the blood, a stroke, strong painkillers, or cancer that has reached the brain. Only an examination and blood tests can sort these out, and some need a scan.
It cannot set medicine doses
How much lactulose to give, and whether rifaximin should be added, are decisions for the treating doctor. They depend on the person's kidneys, their bowel pattern and their other medicines. Read rifaximin and when it is added for background, then ask.
Who this does not apply to
If the person has dementia that was diagnosed before any liver problem, or confusion that started after an injury, the advice here is only part of the picture. Tell the doctor about both conditions.
Questions we are asked
Common questions from carers
Will the confusion go away?
Often, yes. When the trigger is found and treated, many people return to how they were within a short time. Some have repeated episodes, especially if the liver is very weak. The team will try to prevent the next one with regular medicines and by watching for triggers.
Should we take him to a psychiatrist?
Not as the first step. Call the doctor treating the liver or the cancer, because liver-related confusion is treated with liver medicines and by fixing the trigger. If confusion persists after that, the team may suggest a specialist for memory or mood.
Can I give a sleeping tablet to calm her at night?
Only if the treating doctor has prescribed it for this purpose. Many sleeping tablets and sedatives are cleared by the liver and can make confusion much worse, or tip someone into deep drowsiness. Ask before giving anything from the family medicine box.
He refuses his lactulose. What can I do?
Try mixing it with juice or water, offering it at a calm moment, and explaining it simply. Do not force it if he might choke. Tell the treating team the same day, because missed doses can bring confusion back and there may be other ways to give treatment.
Is it safe for him to be left alone?
During an episode, no. Someone confused may leave the gas on, fall at night, take the wrong tablets or walk out of the house. Arrange for someone to stay with them until the doctor says the episode has settled.
Does the confusion mean the cancer has spread to the brain?
Usually not. In liver disease, the liver failing to clear toxins is a far more common cause. Spread to the brain is possible but less likely. The doctor will examine the person and decide whether a brain scan is needed.
Why is he angry with me and not with others?
The person closest to the patient often takes the brunt, simply because they are present most. It is not a judgement on you. Take short breaks when someone else can sit with him, and tell the team if the agitation is putting anyone at risk.
Who can we call when this happens again?
Call the treating team first, with a clear description of what has changed. CION's helpline can guide you to the right team and arrange a supportive care review. If the person is very drowsy, has a fever or is bleeding, go to hospital today instead.
