What is Reyes syndrome?

Reye's syndrome is an emergency illness chiefly affecting children and teenagers. It almost always follows a viral illness such as a cold, the flu, or chicken pox. Reye's syndrome may affect all the organs of the body, but most seriously affects the brain and liver. Rapid development of severe neurological symptoms, including lethargy, confusion, seizures, and coma, make Reye's syndrome a life-threatening emergency. Reye's syndrome is a rare illness, even rarer now than when first described in the early 1970s. The incidence of the disorder peaked in 1980, with 555 cases reported. The number of cases declined rapidly thereafter due to decreased use of aspirin compounds for childhood fever, an important risk factor for Reye's syndrome development. Because of its rarity, it is often misdiagnosed as encephalitis, meningitis, diabetes, or poisoning, and the true incidence may be higher than the number of reported cases indicates.
