Intracerebral haemorrhage awareness
Informed by recognized medical guidance
Overview
An intracerebral haemorrhage (say: in-trah-SER-ee-bral HEM-or-ij) is a type of stroke where a blood vessel inside the brain bursts and bleeds into the brain tissue. This can damage brain cells and cause serious symptoms.
Key facts
- Intracerebral haemorrhage is a medical emergency that needs immediate hospital care.
- It accounts for about 10–15% of all strokes, but it is often more severe than other types.
- Prompt treatment can reduce brain damage and improve chances of recovery.
Intracerebral haemorrhage is less common than the other main type of stroke (ischaemic stroke), but it is a serious condition that affects many people worldwide each year.
It can happen to anyone, but it is more common in older adults, people with high blood pressure, and those who take certain blood-thinning medicines. It can also occur in younger people due to underlying blood vessel problems or injuries.
Symptoms
- Sudden severe headache with no known cause
- One-sided weakness or numbness in the face, arm, or leg
- Sudden confusion, slurred speech, or trouble understanding
- Loss of balance or difficulty walking
- Sudden vision loss or double vision
- Seizure or loss of consciousness
- ⚠Headache that gets worse over minutes or hours
- ⚠Nausea or vomiting after a headache
- ⚠Any new or unusual neurological symptom that is not severe but does not improve
Common symptoms
- Sudden severe headache – often described as the worst headache of your life
- Weakness or numbness on one side of the face, arm, or leg
- Confusion, trouble speaking, or understanding speech
- Difficulty walking, loss of balance or coordination
- Vision problems in one or both eyes
- Nausea or vomiting without a clear cause
Symptoms in children
- Sudden headache that won't go away
- Seizures (convulsions or shaking)
- Extreme sleepiness or difficulty waking up
- Weakness on one side of the body
- Crying or fussiness that is unusual
Symptoms in older adults
- Sudden confusion or change in behaviour
- Fainting or loss of consciousness
- Uneven pupil size
- Trouble speaking or being understood
- Severe headache or neck stiffness
Causes
Main causes
- High blood pressure (the most common cause) – it weakens blood vessel walls over time.
- Bleeding from abnormal blood vessels in the brain, such as arteriovenous malformations or aneurysms.
- Head injury that damages a blood vessel.
- Bleeding disorders or use of blood-thinning medicines.
Risk factors
- Uncontrolled high blood pressure
- Age – risk increases after age 55
- Smoking and heavy alcohol use
- Use of anticoagulant or antiplatelet medicines
- Diabetes, high cholesterol, or a history of stroke
- Certain genetic conditions that affect blood vessels
When to see a doctor
See a doctor urgently if:
- If you or someone else has any of the emergency symptoms listed above, call your local emergency number (such as 999 in the UK, 911 in the US) immediately.
- Do not wait – every minute matters.
Book a routine appointment if:
- If you have high blood pressure or other risk factors, see your doctor regularly to manage them.
- If you experience sudden but mild symptoms that resolve quickly (like a brief weakness or speech difficulty), seek same-day medical advice – this could be a 'mini-stroke' (TIA).
Diagnosis
Diagnosis happens in a hospital emergency department. The doctor will ask about symptoms and medical history, do a neurological exam, and order brain imaging scans.
Tests that may be done
- CT scan (computed tomography) – a special X-ray that shows bleeding in the brain quickly.
- MRI scan (magnetic resonance imaging) – gives a more detailed picture of brain tissue.
- Blood tests – to check for bleeding disorders or other problems.
- Sometimes a cerebral angiogram – a dye test to look at blood vessels.
What to expect at your appointment
You will be asked to stay still for the scans. The process can be fast because time is critical. A team of doctors, nurses, and specialists will work together to decide the best next steps.
Treatment
Treatment focuses on stopping the bleeding, reducing pressure on the brain, and supporting recovery. This is done in a hospital, often in an intensive care unit (ICU) or stroke unit.
Self-care at home
- You cannot treat a brain bleed at home – emergency medical care is essential.
- After hospital, follow all advice from your healthcare team, including taking prescribed medicines as directed.
- Rest and avoid heavy lifting or straining until your doctor says it is safe.
Medical treatments
Doctors may give medicines to lower blood pressure and reduce swelling in the brain. Blood-thinning medicines may be stopped or reversed. You may receive oxygen or medicines to control seizures. Treatment is tailored to your individual situation.
When is surgery considered?
Surgery may be needed to remove the clot or relieve pressure on the brain. This depends on the size and location of the bleed and the person's overall health.
Living with this condition
Recovery from intracerebral haemorrhage takes time. You may need rehabilitation, including physical therapy, speech therapy, and occupational therapy. Many people improve gradually, but some may have lasting changes.
Lifestyle tips
- Keep blood pressure under control – take medicines as prescribed and monitor your blood pressure at home if advised.
- Avoid smoking and limit alcohol.
- Attend all follow-up appointments and therapy sessions.
- Make your home safe to prevent falls – remove loose rugs, install handrails.
Diet and exercise
A heart-healthy diet – low in salt, rich in fruits, vegetables, and whole grains – can help control blood pressure. Gentle exercise like walking, with your doctor's approval, can support recovery. Avoid heavy lifting or activities that might raise blood pressure suddenly.
Mental health and emotional wellbeing
It is common to feel anxious, depressed, or frustrated after a brain bleed. Emotional changes can be part of the injury itself. Talk to your healthcare team – they can offer support, counselling, or connect you with a psychologist.
Prevention
You cannot always prevent an intracerebral haemorrhage, but you can lower your risk by managing high blood pressure, not smoking, limiting alcohol, and treating any underlying blood vessel problems. If you take blood thinners, take them exactly as prescribed and have regular check-ups.
Complications
If left untreated
- Increased pressure on the brain, which can cause more damage.
- Loss of consciousness or coma.
- Permanent brain injury affecting movement, speech, or thinking.
- In severe cases, it can be life-threatening.
Long-term outlook
Outcomes vary widely. With fast treatment and rehabilitation, many people recover significantly. Some may have lasting disabilities, but support and therapy can improve quality of life. The best chances come from getting care immediately and following through with recovery plans.
