The symptoms of Reye's syndrome usually begin a few days after a viral infection.
Persistent or continuous vomiting and/or:
Signs of cerebral oedema:-
- Loss of Energy
- Aggressive behaviour
- Irrational behaviour
Reye's syndrome should be suspected if a child displays all or part of this pattern of symptoms a few days after the onset of viral infection such as 'flu' or chickenpox. Fever is not usually present. Many diseases have similar features. Medical staff who do not have experience of Reye’s syndrome may initially suspect encephalitis, meningitis, poisoning, mental illness or even drug abuse. In infants the symptoms of Reye's syndrome may not follow a typical pattern; for example vomiting is less common. However, it should be emphasised that it is in infants that the "Reye-like syndromes" are most likely to occur.
