Cerebellar Stroke
Overview
A cerebellar stroke happens when the blood supply to the cerebellum — the part of the brain at the back of the head that controls balance and coordination — is interrupted. This can be because a blood vessel is blocked by a clot or because a blood vessel bursts and bleeds into the brain. It is a medical emergency.
Key facts
- The cerebellum controls balance, coordination, and fine movement.
- Cerebellar strokes are less common than strokes in other parts of the brain, but they can be serious.
- They often cause sudden dizziness, vomiting, and trouble walking.
- Quick treatment can help prevent permanent disability and can even save your life.
Cerebellar strokes are relatively rare, making up about 1 in 10 of all strokes. But they are still a leading cause of balance problems and hospitalisation.
Anyone can have a cerebellar stroke, but they are more common in older adults, people with high blood pressure, diabetes, or heart disease, and those who smoke. Rarely, they can happen in children or young adults, sometimes due to a head injury or a problem with the blood vessels in the brain.
Symptoms
- Any sudden symptom, such as severe dizziness, loss of balance, trouble walking, vomiting, a sudden severe headache, difficulty speaking, or weakness or numbness on one side of the body — call your local emergency number right away.
- Never wait to see if symptoms get better. A stroke is a medical emergency and needs immediate hospital care.
- ⚠If you have brief or mild symptoms that go away on their own, such as a few minutes of dizziness, unsteadiness, or trouble speaking, you may have had a transient ischaemic attack (TIA, sometimes called a mini-stroke).
- ⚠This still needs a same-day urgent appointment with your doctor or hospital. Do not ignore it.
Common symptoms
- Sudden severe dizziness or vertigo (feeling like everything is spinning)
- Loss of balance or coordination
- Trouble walking or standing
- Vomiting or nausea
- Headache, especially at the back of the head
- Difficulty speaking or slurred speech
- Double vision or other vision changes
- Numbness or weakness on one side of the body (though this is less common than with other strokes)
Symptoms in children
- Sudden unsteadiness or clumsiness
- Headache
- Vomiting
- Unusual tiredness or irritability
- Refusing to walk or difficulty sitting up
- A possible head injury, as a cause
Symptoms in older adults
- Sudden loss of balance or a fall
- Severe dizziness
- Confusion or disorientation
- Headache
- Difficulty coordinating movements
- Sudden hearing loss or ringing in the ears
- Sometimes no other typical stroke signs, so it can be missed
Causes
Main causes
- A blood clot blocking a blood vessel in the cerebellum (ischaemic stroke)
- A blood vessel in the cerebellum bursting and bleeding (haemorrhagic stroke)
- Less commonly, a blood vessel that is temporarily narrowed, often due to a small blood clot, causing a transient ischaemic attack (TIA)
- In children, a blow to the head or a problem with blood vessels in the brain
Risk factors
- High blood pressure
- High cholesterol
- Diabetes
- Smoking
- Drinking too much alcohol
- Being overweight
- Heart problems, such as atrial fibrillation (an irregular heartbeat)
- A family history of stroke
- Being older (over 65)
- For women, using certain types of birth control pills or hormone replacement therapy, especially if you also smoke
When to see a doctor
See a doctor urgently if:
- Call emergency services if you or someone else shows any sudden signs of a stroke, such as severe dizziness, loss of balance, trouble walking, slurred speech, or a sudden severe headache.
- If you have had brief stroke-like symptoms that went away, get medical help the same day to be checked for a transient ischaemic attack (TIA).
Book a routine appointment if:
- If you have risk factors such as high blood pressure or diabetes, see your doctor regularly to keep them under control.
- If you have been having balance problems or persistent headaches, book a routine appointment to discuss them.
Diagnosis
A doctor will ask about your symptoms and medical history, perform a physical exam, and order imaging scans of your brain. They will also check your blood pressure, heart, and blood tests to help find the cause.
Tests that may be done
- Brain imaging scans, such as a CT scan or MRI scan, to look for blocked or bleeding blood vessels
- Blood tests to check for clotting problems, high cholesterol, or other risk factors
- An electrocardiogram (ECG) to check your heart rhythm
- Carotid ultrasound to see if the neck arteries are narrowed
- In some cases, a more detailed test of the blood vessels, such as an angiogram
What to expect at your appointment
You will be admitted to a specialist stroke unit in the hospital. The team will quickly run tests to confirm the diagnosis and start treatment. This may include nursing care, medication, and therapy to help you recover. Expect to stay in hospital for at least a few days, depending on your condition.
Treatment
Treatment for a cerebellar stroke aims to restore blood flow or stop bleeding quickly, prevent further damage, and then support your recovery. It will depend on the type of stroke, how serious it is, and how soon you get to hospital.
Self-care at home
- Follow your stroke team's advice on medicines and therapy
- Rest when you feel tired
- Get help at home for tasks you cannot do safely
- Ask about fall prevention if you have balance problems
- Gradually increase activity under the guidance of a physical therapist
- Seek support from family or a stroke support group for emotional issues
Medical treatments
For an ischaemic stroke (caused by a clot), the main treatment is a clot-busting medication given through a drip, if you are eligible and arrive soon after symptoms start. Sometimes, a procedure may be done to remove the clot. For a haemorrhagic stroke (caused by bleeding), the focus is on lowering blood pressure and managing bleeding risk. After the acute phase, you may be given medicines to prevent another stroke, such as antiplatelet or anticoagulant medication (to prevent clots), and medicines to control blood pressure and cholesterol. Your doctor will explain the right plan for you.
When is surgery considered?
Surgery is sometimes needed if bleeding is severe, a large clot is pressing on the brain, or there is swelling in the brain that threatens your life. This might involve draining the blood or a procedure to relieve pressure. Your care team will discuss this with you if it is needed.
Living with this condition
Recovery from a cerebellar stroke can be slow and take weeks or months. You might have trouble with balance, coordination, and fatigue. It is common to need help at home initially. With rehabilitation, many people improve a lot, though some may have long-term difficulties. A stroke team will help you set goals and adapt your daily routines to stay as independent as possible.
Lifestyle tips
- Take any prescribed medicine exactly as directed
- Go to all follow-up appointments
- Get support from a physiotherapist to improve balance and strength
- Work with an occupational therapist to adapt your home and routines
- Join a stroke support group or online community
- Ask for help with emotional or psychological difficulties
Diet and exercise
A healthy diet can help your recovery and lower your risk of another stroke. This includes eating plenty of fruits and vegetables, whole grains, and lean proteins, while limiting salt, sugar, and saturated fat. Your stroke team may refer you to a dietitian. Regular physical activity, such as walking or chair exercises, can help improve strength and balance, but only do exercises your physiotherapist or doctor approves, and start slowly.
Mental health and emotional wellbeing
A cerebellar stroke can be a frightening and life-changing event. It is normal to feel anxious, sad, or frustrated during recovery. These feelings are real and you are not alone. Talk to your care team about how you are feeling. Many hospitals have psychologists who specialise in stroke recovery. If you ever have thoughts of suicide, please seek urgent support from your local crisis helpline or emergency services.
Prevention
Most strokes are preventable if you manage your risk factors. The most important things are keeping your blood pressure under control, not smoking, being active, eating healthily, and taking your prescribed medicines. If you have a heart condition such as atrial fibrillation, treating it can greatly lower your stroke risk. Your doctor can help you create a personal prevention plan.
Vaccines
Some infections, such as flu and COVID-19, can increase the risk of stroke in people with existing health problems. Staying up to date with recommended vaccines is a simple way to protect yourself. Ask your doctor or pharmacist which vaccines are right for you.
Screening programmes
There is no routine screening test for stroke in the general population. But if you have high blood pressure, diabetes, or an irregular heartbeat, your doctor will monitor you regularly and may do tests to check your vascular health. This helps you and your team keep your risk factors in check.
Complications
If left untreated
- A cerebellar stroke can be fatal if not treated quickly, because swelling can press on the brain stem, which controls breathing and the heartbeat
- Bleeding can increase and lead to more brain damage
- There is a risk of blood clots in the lungs or another stroke
- Loss of balance and coordination, if left untreated, can lead to falls and further injury
- Some people may have long-term disability, such as trouble walking or speaking, if rehabilitation is delayed
Long-term outlook
The outlook after a cerebellar stroke is better than many people think. Many survivors improve significantly over the first few months, especially with prompt medical care and rehabilitation. Some people go on to live with little or no disability. Others may have lasting balance or coordination problems, but they can often learn to adapt and continue to live full lives. The most important thing is to get treatment fast, attend rehabilitation, and prevent another stroke. Your team will work with you, and progress often comes in small steps.
