Reye’s Syndrome

Reye’s syndrome is a rare condition that causes your brain to swell and your liver to lose function after a viral illness or infection like the flu or chickenpox. It’s most common among children who take aspirin to treat symptoms during a viral infection or illness. The condition develops up to one week after the onset of a viral illness.

Who does Reye’s syndrome affect?

Reye’s syndrome is primarily a children’s disease, although it can occur at any age. Cases usually happen in the fall and winter seasons and are present in children younger than 18 years old.

How common is Reye’s syndrome?

An estimated two children per year in the United States develop Reye’s syndrome.

The frequency of Reye’s syndrome declined because of heightened awareness of the condition. If your child is sick, don’t give them aspirin to treat their symptoms. Vaccinations for the flu and chickenpox (varicella) are successful at preventing viral infections, which also contributes to a low number of cases each year.

How does Reye’s syndrome affect my child’s body?

After a viral illness or infection, like the flu or chickenpox, your child may show new symptoms up to one week after their primary illness or infection. It’s important that you don’t treat your child’s symptoms with aspirin, which could lead to Reye’s syndrome, without first consulting your healthcare provider.

Since Reye’s syndrome causes pressure to build in your child’s brain, their personality could change suddenly. Your happy child could show a lack of interest in their favorite activities or get angry or bothered by something that normally wouldn’t be a problem. Early signs of Reye’s syndrome, like changes to your child’s mental state, could lead to an early diagnosis and treatment, which leads to the best outcome for their health.
