Huntington's Disease Symptoms: A Guide for Care Teams

Huntington's disease symptoms fall into three groups: movement, thinking and mood. Early signs include small jerky movements the person can't control (chorea), clumsiness, difficulty concentrating or planning, memory problems, low mood, anxiety and irritability. Later, speaking and swallowing get harder, muscles stiffen, weight drops and mood changes become more severe. Symptoms usually start between 30 and 50, but can begin at any age.

What Huntington's disease is

Huntington's disease is an inherited condition that damages parts of the brain and gets worse over time. The NHS says there is currently no cure and no treatment that stops symptoms getting worse, but treatment and good care help people stay comfortable and independent for as long as possible. Most people live for many years after symptoms start, and eventually need help with daily living.

Treatment focuses on managing symptoms and supporting the person and their family. Research is active, so ask the person's specialist team about anything new.

You'll still hear the older name, Huntington's chorea. Chorea comes from the Greek word for dance and describes the jerky movements many people have. The name undersells it, though: the Huntington's Disease Association (HDA) notes that the emotional and psychological changes can be a bigger problem than the physical ones.

Huntington's disease symptoms

Symptoms vary widely, even between people in the same family. They usually affect three areas.

Movement

• Small twitches or jerks the person can't control (chorea)
• Clumsiness, stumbling and difficulty controlling muscles
• Later, stiff muscles, involuntary muscle contractions and slower, more effortful movement
• Changes in speech and difficulty swallowing

Thinking (cognitive symptoms)

• Difficulty concentrating
• Short-term memory lapses
• Difficulty organising and planning, including everyday tasks

Mood and behaviour (psychiatric symptoms)

• Low mood, depression and anxiety
• Irritability, impulsiveness and changes in personality
• Anger and frustration, which can become more intense as the condition progresses

On shift, early changes can look like something else: someone who seems short-tempered, forgets the plan you agreed an hour ago, or keeps dropping things. Many of these symptoms have other causes, so don't jump to conclusions. Record what you notice and pass it on to the person's GP or specialist team.

How Huntington's progresses

Huntington's progresses over many years. The HDA describes early, middle and later stages. Nobody moves through them on a timetable, and doctors can't predict exactly when symptoms will start.

• Early stage: chorea, clumsiness, poor concentration, memory lapses, irritability, depression and personality changes.
• Middle stage: muscle contractions, stiffness, slower movement, changes in speech, difficulty swallowing, and more intense anger, frustration or depression.
• Later stage: weight loss, greater difficulty with speech and swallowing, and communication difficulties. People need much more care and support.

Juvenile Huntington's disease

When symptoms start before the age of 20, it's called juvenile Huntington's disease. The HDA says it affects fewer than 10% of people with Huntington's, and that it often looks different from the adult form:

• Chorea is less common; stiffness and muscle contractions are more common.
• Epilepsy is more common, especially in younger children.
• The first signs are often changes in thinking or behaviour, such as trouble concentrating or following instructions, or a drop in school performance. These can be mistaken for laziness.
• Earlier onset generally means faster progression.

Because it's so rare, the HDA encourages families and schools to work closely together. Small changes help, such as more time to eat and frequent snacks.

The genetics in plain terms

Huntington's is caused by a fault in a gene called huntingtin (HTT). It's inherited, not caught. Every child conceived naturally to a parent with the faulty gene has a 50% chance of inheriting it, and it affects both men and women. Someone who inherits it can have no symptoms for years, but will develop the condition at some point.

The fault is a stretch of the gene's code, called a CAG repeat, that is longer than usual. The HDA explains that 40 or more repeats means a person will develop Huntington's, and very long repeats (more than 50) are strongly linked to juvenile onset. The repeat is less stable when passed on by a father: around 90% of people with more than 50 repeats inherited it from their father.

A predictive genetic test is available from age 18, with a genetic counsellor to help people decide whether they want to know. Some people you support will know their status and some won't, and relatives may be living with their own risk. Treat it as confidential.

What it means for care

A multidisciplinary team usually supports the person, which can include neurology, speech and language therapy, physiotherapy, occupational therapy and mental health support. Your team's job is to notice changes early and follow your local policy and the person's care plan.

Swallowing and nutrition

Swallowing problems (dysphagia) increase the risk of choking. At the same time, the HDA explains that involuntary movements use extra energy, so people often need noticeably more food than usual to keep their weight steady. Poor coordination, forgetting to eat and low mood can all reduce intake. Follow the speech and language therapist's recommendations exactly, weigh people as the care plan says, and report weight loss or coughing at mealtimes. See our dysphagia awareness training for staff who support people at mealtimes.

Falls and moving safely

Stumbling, clumsiness and involuntary movements raise the risk of falls. Keep walkways clear and review the falls risk assessment whenever movement changes. Falls prevention training helps the whole team spot risks in the same way.

Communication

Speech often becomes harder to understand, and following a conversation can take more effort. Give people time, ask one question at a time and don't finish their sentences. It helps to agree ways of communicating early, so record what works while speech is still clear.

Mood and mental health

Depression, anxiety and irritability are part of the condition, not a character flaw. Keep routines predictable, offer choices, and take any talk of hopelessness seriously: report it and follow your procedures. Families and carers often need support too.

Capacity and planning ahead

As Huntington's progresses, a person's capacity to make some decisions may change. In England and Wales, the Mental Capacity Act 2005 sets out how decisions are made with and for people who may lack capacity. So start conversations about future wishes, including end of life care, early, while the person can lead them. End of life care training supports staff through those later conversations.

How Kasorb can help

Kasorb's Huntington's disease awareness training helps care staff understand this inherited neurological condition, its genetics, symptoms and progression, and how to provide safe, person-centred care through to the end of life. The session covers how Huntington's presents across movement, thinking and mood, diagnosis and treatment, living with and caring for someone with Huntington's, and planning for end of life care.

It runs for half a day, on-site anywhere in the UK or live online, for up to 12 staff per session. Run two sessions in one day to train up to 24 staff, at one flat rate. Your trainer has used these skills for real, and can focus the session on someone you support if you share anonymised details in advance. Certificates are emailed the next day.

FAQs

What are the first signs of Huntington's disease?

Early signs often include small jerky movements the person can't control, clumsiness, difficulty concentrating or planning tasks, memory problems, low mood, anxiety and irritability or impulsiveness. Many of these signs are common and have other causes, so anyone worried about themselves or a relative should see their GP.

Is Huntington's chorea the same as Huntington's disease?

Yes. Huntington's chorea is an older name for the same condition. Chorea describes the jerky, dance-like movements many people have. Huntington's disease is the name the NHS and the Huntington's Disease Association use, and it reflects that the condition affects thinking, mood and behaviour as well as movement.

What age does Huntington's disease start?

Symptoms usually start between the ages of 30 and 50, but can begin at any age. When symptoms start before 20 it's called juvenile Huntington's disease, which the Huntington's Disease Association says affects fewer than 10% of people with the condition. Doctors can't predict exactly when symptoms will begin.

If a parent has Huntington's, will their child get it?

Not necessarily. Each child conceived naturally to a parent with the faulty gene has a 50% chance of inheriting it, and anyone who inherits it will develop Huntington's at some point. A predictive genetic test is available from age 18, with a genetic counsellor to help people decide whether they want to know.

How long do people live with Huntington's disease?

The NHS says Huntington's affects how long people live but gives no set figure, and most people live for many years after symptoms start. The condition progresses over many years, and eventually people need help with daily living. Planning ahead early helps people stay in control of their care.
