Reye syndrome

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 behaviour. 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).
