Overview

Encephalitis is a swelling (inflammation) in the brain. It is usually caused by a virus. The normal blood flow to the brain changes. This can cause confusion, a high fever, and a severe headache. Your child also may be sleepy and sensitive to light and may have nausea and a stiff neck and back. In the most serious cases, a child may have seizures or tremors.

Your doctor may prescribe medicine to help your child's body get rid of the virus. Your child may have some symptoms for several weeks or longer while their body slowly heals. Your doctor may recommend physiotherapy to help your child get stronger and active again.

How can you care for your child at home?

• Ask your doctor if you can give your child acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) for pain and discomfort. Do not use ibuprofen if your child is less than 6 months old unless the doctor gave you instructions to use it. Be safe with medicines. Read and follow all instructions on the label. Do not give aspirin to anyone younger than 18. It has been linked to Reye syndrome, a serious illness.
• Do not give your child two or more pain medicines at the same time unless the doctor told you to. Many pain medicines have acetaminophen, which is Tylenol. Too much acetaminophen (Tylenol) can be harmful.
• Have your child drink plenty of fluids. If your child has to limit fluids because of a health problem, talk with your doctor before you increase how much your child drinks.
• Make sure your child eats a healthy, balanced diet and gets plenty of rest to help their body heal.
• Keep the lights dim if your child's eyes are sensitive to light.
