stroke recovery in children

Overview

A stroke happens when blood flow to part of the brain is blocked or when a blood vessel in the brain bursts. This damages brain cells. When this happens in a child, it is called a childhood stroke or paediatric stroke. The brain can often rewire itself after injury, especially in children, so recovery is possible with the right care and support.

Stroke in children is rare. It affects about 1 in every 2,000 to 4,000 children each year, but the exact number is hard to know. It is much less common than stroke in adults.

It can affect newborn babies, infants, children, and teenagers. Very young children, especially in the first year of life, are the most likely group to have a stroke. It can happen in any child, including those who seem healthy until the stroke occurs.

Symptoms

Common symptoms

• Sudden weakness or numbness on one side of the body, face, or leg
• Trouble speaking, understanding, or swallowing
• Sudden severe headache, often with vomiting
• Loss of balance or coordination
• Sudden vision changes, like double vision or trouble seeing
• Confusion, dizziness, or a seizure

Symptoms in children

• In babies: seizures, unusual irritability or drowsiness, feeding difficulties, breathing pauses, or a tense/full soft spot on the top of the head.
• In older children: a sudden change in speech, movement, or behavior, weakness on one side, clumsiness, or a severe headache that is different from usual.
• Strokes in children can also cause learning problems or behavior changes that are noticed later.

Symptoms in older adults

• For older adults, the classic warning signs are the FAST signs: Face drooping, Arm weakness, Speech difficulty, and Time to call emergency services. These signs are less common but still possible in children.

Causes

Main causes

• In children, the most common causes include congenital heart problems (heart defects present at birth)
• Blood clotting disorders
• Infections that inflame blood vessels in the brain, such as meningitis
• Sickle cell disease
• Injury to the head or neck
• In newborns, strokes may occur during birth or in the first month of life due to blood vessel problems or blood clotting issues

Risk factors

• Heart defects
• Sickle cell disease
• Infections like meningitis
• Dehydration
• Head or neck trauma
• Blood clotting disorders
• A previous stroke in the family (though most childhood strokes are not inherited)

When to see a doctor

See a doctor urgently if:

• Call emergency services immediately if your child shows sudden limb weakness, facial drooping, severe headache, trouble speaking, confusion, or a seizure. Do not wait to see a doctor.

Book a routine appointment if:

• If your child has a known heart condition, sickle cell disease, or a blood clotting condition, keep all regular check-ups.
• Talk to your child's doctor if you notice new headaches, balance problems, or changes in behavior or school performance.

Diagnosis

A child who may have had a stroke will be examined promptly in a hospital. A specialist will ask about symptoms and do imaging tests to look at the brain. They may also test blood, the heart, and the blood vessels in the head and neck.

Tests that may be done

• Brain imaging (such as CT or MRI scan) — this is the main test to diagnose stroke.
• Magnetic resonance angiography (MRA) or CT angiography to look at blood vessels in the brain.
• Echocardiogram to check the heart's structure and function, since some strokes in children start from the heart.
• Blood tests, including tests for blood clotting problems.
• EEG (shows the brain's electrical activity) if the child has had a seizure.

What to expect at your appointment

The hospital team will explain each step. Imaging scans are painless and usually take less than an hour. Your child may need special medicine to keep still during a scan, especially if they are young or anxious. Blood tests are quick. You will be encouraged to stay close and ask questions.

Treatment

Treatment for a child's stroke focuses on stopping the stroke if it is happening, preventing another one, and helping the brain recover. The recovery plan will be tailored to your child, depending on the cause and how severe the stroke was.

Self-care at home

• Therapies at home and hospital—such as physical, speech, and occupational therapy—are part of daily life during recovery.
• Keep a routine for meals, sleep, and play to help your child feel safe.
• Use simple language and give your child extra time during conversations.
• Encourage small, enjoyable activities that build skills without frustration.

Medical treatments

Doctors may use medicines to reduce the risk of another stroke, such as blood-thinning medicines or medicines to control blood pressure, seizures, or underlying conditions like sickle cell disease. They will only be prescribed by a specialist. In some cases, the cause of the stroke is treated with a procedure to open a narrowed blood vessel or to repair a heart defect.

When is surgery considered?

Surgery may be considered if the stroke was caused by a heart defect, a weakened blood vessel (aneurysm), or an abnormal tangle of blood vessels in the brain (arteriovenous malformation). The decision to operate is made by a specialist team after detailed tests.

Living with this condition

Recovery from a childhood stroke is often a slow, gradual journey. Many children improve over months to years because their brains are still developing. You will work with a team of therapists, teachers, and doctors to make a plan for home, school, and community activities.

Lifestyle tips

• Help your child stay physically active in ways they enjoy, such as swimming, cycling, or playing in the park.
• Make sure your child gets enough sleep, as sleep helps the brain recover.
• Keep follow-up appointments with the stroke team, even when your child seems fine.
• Encourage social activities with friends and family to support mood and confidence.

Diet and exercise

A balanced diet helps support recovery and overall health. Include fruits, vegetables, whole grains, and foods rich in omega-3 fatty acids (such as oily fish). Unless your child's doctor says otherwise, aim for a healthy meal plan and regular physical activity that suits your child's abilities.

Mental health and emotional wellbeing

A stroke can affect the whole family. Children may feel frustrated, worried, or sad about their changes. Parents also often experience stress and fatigue. It is important to acknowledge these feelings and seek help if they become overwhelming.

Prevention

Many childhood strokes are not preventable because they happen for reasons that cannot be predicted. However, treating underlying conditions (such as sickle cell disease or heart defects) and responding quickly to symptoms can reduce the chance of a second stroke and improve recovery.

Vaccines

There is no vaccine to prevent stroke, but keeping up with routine childhood immunisations protects against infections like meningitis that can increase stroke risk.

Screening programmes

Children with known risk factors, such as heart disease or blood clotting disorders, are monitored regularly. There is no routine screening test for stroke in otherwise healthy children.

Complications

If left untreated

• If a stroke is not recognised quickly, brain damage may be more extensive, leading to lasting physical disability or learning difficulties.
• Untreated strokes can increase the risk of a second stroke.
• Delayed rehabilitation can make it harder for the brain to re-learn important skills, such as walking, talking, and using the hands.

Long-term outlook

With prompt treatment and a good rehabilitation plan, many children make strong recoveries. Some may have lasting weaknesses, but children's brains can adapt in amazing ways. Most children with a stroke go on to lead meaningful lives, learn, and make friends. Having the right support makes a big difference.
