ICD-11 definition : Reye syndrome is sudden (acute) brain damage (encephalopathy) and liver function problems
of unknown cause. The syndrome has occurred with the use of aspirin to treat chickenpox
or the flu in children. However, it has become very uncommon since aspirin is no longer
recommended for routine use in children. Reye syndrome often begins with vomiting,
which lasts for many hours. The vomiting is quickly followed by irritable and aggressive
behavior. There is no specific treatment for this condition. The health care provider
will monitor the pressure in the brain, blood gases, and blood acid-base balance (pH).;
