What is Reye’s syndrome?
Reye’s syndrome is a rare condition that affects the brain and liver. It often develops in young children after they’ve had a viral illness like flu or chickenpox. Symptoms typically appear 1 to 3 weeks after recovery and can progress rapidly.
Reye’s syndrome is a medical emergency, recognising symptoms quickly can help improve a child’s recovery.
The condition mostly affects children aged 5 to 14 years, but it can also happen in younger children and adults.
What causes Reye’s syndrome?
The exact cause of Reye’s syndrome is unknown, but it has been linked to the use of aspirin in treating viral infections in children. Because of this, aspirin is not recommended for children under 16 unless advised by a doctor.
Other possible causes include:
- Viral infections
- Some inherited metabolic conditions
- Certain medications
Reye’s syndrome is now very rare thanks to increased awareness of aspirin use in children.
What are the symptoms of Reye’s syndrome?
Symptoms often develop quickly and may include:
- Persistent vomiting that doesn’t improve
- Unusual drowsiness or low energy
- Confusion
- Changes in behaviour
- Changes in breathing or heart rate
- Seizures
- Loss of consciousness
Because Reye’s syndrome can worsen quickly, recognising the early signs and seeking medical help as soon as possible is important.
If your child has recently had a viral illness and develops persistent vomiting alongside confusion or unusual behaviour, contact a doctor without delay.
