What is Reye's Syndrome

Reye's syndrome is an acute disorder which affects children when they seem to be recovering from a viral illness like 'flu', chickenpox or diarrhoea. The child has a change in his/her personality or becomes drowsy and develops frequent or persistent vomiting. Unless diagnosed and treated successfully, death or severe disability may result.

Abnormal accumulations of fat develop in the liver and some other organs of the body. There is swelling of the brain which can cause it injury. The disease affects children from infancy onwards, including teenagers and has been reported, albeit rarely, in adults. Children of both sexes and all races can be affected.
